This <a href=\"https:\/\/www.pcmag.com\/news\/samsung-to-mass-produce-solid-state-batteries-for-super-premium-evs-by\" target=\"_blank\" rel=\"noreferrer noopener\">next-generation battery<\/a> is set to redefine the <a href=\"https:\/\/greyb.com\/blog\/electric-vehicle-companies\/\" target=\"_blank\" rel=\"noreferrer noopener\">electric vehicle (EV) market,<\/a> offering an unprecedented range of up to 965 kilometers on a single charge and recharging in just 9 minutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These state-of-the-art solid-state batteries also have a life span of 20 years. Testing batches of these batteries have already been shipped to major automotive manufacturers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Solid-state batteries (SSBs) present a compelling alternative to traditional lithium-ion (Li-ion) batteries. SSBs offer advantages in terms of size, weight, safety, capacity, and recharging speed. Because they lack a liquid electrolyte, they can be smaller and lighter, making them ideal for applications such as electric vehicles (EVs).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, SSBs boast faster charging times, with claims of reaching 80% charge in as little as 10-15 minutes, <a href=\"https:\/\/greyb.com\/blog\/redox-flow-batteries-lithium-alternative\/\" target=\"_blank\" rel=\"noreferrer noopener\">compared to Li-ion batteries,<\/a> which can take longer to charge. SSBs can also offer a higher energy density per cell, typically between 300 Wh and 400 Wh, compared with traditional batteries. Moreover, SSBs offer greater energy density, enabling longer driving ranges on a single charge.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/solid-state-lithium-metal-batteries.png\" alt=\"solid-state-lithium-metal-batteries\" class=\"wp-image-43247\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">With their enhanced safety features, higher thermal stability, and potential for lower carbon footprints, SSBs represent a significant advancement in battery technology and could revolutionize various industries. Properties like these attracted many EVs and <a href=\"https:\/\/greyb.com\/blog\/battery-energy-storage-companies\/\" target=\"_blank\" rel=\"noreferrer noopener\">energy storage systems (ESS) players<\/a> to Solid State Batteries (SSB).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite these advantages, SSBs still face significant challenges. For instance, the new Samsung batteries have high production costs and are expected to be available for high-end EVs for the initial phase.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We have discussed those challenges in detail later in this article. However, if companies (like yours) solve these issues, it would be a <a href=\"https:\/\/greyb.com\/blog\/ev-battery-startups\/\" target=\"_blank\" rel=\"noreferrer noopener\">massive step for the EV <\/a>and Energy Storage industries.<\/p>\n\n\n<div class=\"hubspot-form-container\" id=\"hsf\"><div class=\"hubspot-form-pictures\"><img decoding=\"async\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2024\/08\/Energy-storage-trends-mockup.png\" \/><\/div><text><script charset='ecutf-8' type='text\/javascript' src='\/\/js.hsforms.net\/forms\/embed\/v2.js'><\/script><script >hbspt.forms.create({region: \"na1\",portalId: \"1791848\",formId: \"0361278d-ca51-44dc-a6f1-5f7869eeb542\"});<\/script><\/text><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Here are 10 solid state battery companies leading the research:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Toyota<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Toyota has been building <a href=\"https:\/\/greyb.com\/blog\/toyota-solid-state-battery\/\">its solid-state battery<\/a> research program since 2010, and with nearly 2,000 patents filed and commercial production targeted for 2026, its IP and materials science work offers some of the richest data points in the field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Toyota&#8217;s most-cited research milestone came in 2011, when its team, in partnership with the Tokyo Institute of Technology, developed the world&#8217;s first lithium superionic conductor. It was capable of conducting lithium ions more effectively at room temperature in the solid state than in the liquid state. This material doubled the ionic conductivity of existing lithium-ion conductors.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By 2016, the team improved on this with Li\u2089.\u2085\u2084Si\u2081.\u2087\u2084P\u2081.\u2084\u2084S\u2081\u2081.\u2087Cl\u2080.\u2083, demonstrating an exceptionally high conductivity of 25 mS cm\u207b\u00b9 and a near-zero voltage against lithium metal, indicating high electrochemical stability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A January 2025 study published in the <em>Journal of the American Chemical Society<\/em>, conducted in collaboration with Toyota, identified copper nitride (Cu\u2083N) as a high-performance cathode material for all-solid-state fluoride-ion batteries (FIBs).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cu\u2083N exhibits a reversible capacity of approximately 550 mAh\/g \u2014 three times the volumetric capacity and twice the gravimetric capacity of conventional lithium-ion cathodes. This could potentially double EV driving range from 600 km to 1,200 km.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">R&amp;D Focus Areas as per Patents<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Toyota&#8217;s ~2,000 SSB patents target four core technical problems:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Charging speed \u2014 Patent <a href=\"https:\/\/slate.greyb.com\/engage\/US20230387412A1\">US20230387412A1<\/a> uses graphite particles with a sulfide solid electrolyte to reduce ion transport resistance; <a href=\"https:\/\/slate.greyb.com\/engage\/US20240021797A1\">US20240021797A1<\/a> deploys a fluorine-phosphorus composite coating to cut resistance under high voltage.<\/li>\n\n\n\n<li>Battery longevity \u2014 Patent <a href=\"https:\/\/slate.greyb.com\/engage\/US20240038972A1\">US20240038972A1<\/a> uses alternating fluoride-sulfide electrolyte layers to reduce resistance degradation over charge cycles.<\/li>\n\n\n\n<li>Energy density \u2014 Patent <a href=\"https:\/\/slate.greyb.com\/engage\/US20230299337A1\">US20230299337A1<\/a> achieves stable performance at low restraint pressure (\u22640.5 MPa) using sulfide electrolyte-coated composite particles; <a href=\"https:\/\/slate.greyb.com\/engage\/US20220328815A1\">US20220328815A1<\/a> addresses Si-anode volume expansion during cycling<\/li>\n\n\n\n<li>Compact cell design \u2014 Patent <a href=\"https:\/\/slate.greyb.com\/engage\/US20220200057A1\">US20220200057A1<\/a> details a metal-case enclosure with welded current collector layers to eliminate welding clearance and maximize energy density<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Technology Roadmap<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Toyota plans to begin SSB production in 2026 and launch SSB-powered vehicles in 2027, targeting a 10-minute fast charge (10\u201380%) and up to 745 miles of range. The company intends to introduce SSBs in a hybrid vehicle before moving to full BEVs, and aims to sell 3.5 million EVs annually across 30 Toyota and Lexus model lines by 2030.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"624\" height=\"283\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-19.png\" alt=\"image\" class=\"wp-image-111380\" srcset=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-19.png 624w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-19-300x136.png 300w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-19-150x68.png 150w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/><figcaption class=\"wp-element-caption\">Source: Toyota<\/figcaption><\/figure>\n\n\n<div class=\"related-articles-container\"><h4 class =\"related-articles-container-title\">Toyota&#039;s Complete Research Analysis in Solid State Batteries<\/h4><div class=\"related-article\"><div class=\"related-article-thumbnail-container\"><img decoding=\"async\" width=\"792\" height=\"302\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/toyota-solid-state-battery-fi-1.jpg\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image\" alt=\"Toyota Solid State Battery Research\" srcset=\"https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/toyota-solid-state-battery-fi-1.jpg 792w, https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/toyota-solid-state-battery-fi-1-300x114.jpg 300w, https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/toyota-solid-state-battery-fi-1-150x57.jpg 150w, https:\/\/greyb.com\/wp-content\/uploads\/2024\/12\/toyota-solid-state-battery-fi-1-768x293.jpg 768w\" sizes=\"(max-width: 792px) 100vw, 792px\" \/><\/div><div class=\"related-article-content-container\"><div class=\"related-article-title\"><a href=\"https:\/\/greyb.com\/blog\/toyota-solid-state-battery\/\">Toyota to Revolutionize EVs with its Disruptive Solid-State Batteries<\/a><\/div><a href=\"https:\/\/greyb.com\/blog\/toyota-solid-state-battery\/\" class=\"button-read-post\">Read Post <i class=\"arrow-right teenyicon ti-arrow-right\"><\/i><\/a><\/div><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">2. Samsung SDI<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Samsung SDI holds over 1,100 patents related to all-solid-state battery technology, which the company <a href=\"https:\/\/www.thestar.com.my\/business\/business-news\/2026\/03\/13\/lg-energy-samsung-sdi-flex-patent-muscle\">reaffirmed<\/a> at InterBattery 2026 in Seoul. Samsung further revealed a new name for its all-solid-state battery technology, SolidStack.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With mass production targeted for 2027 and a robots-first commercialization strategy, Samsung SDI&#8217;s R&amp;D trajectory is both technically deep and commercially deliberate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Samsung SDI&#8217;s influential research milestone was <a href=\"https:\/\/www.nature.com\/articles\/s41560-020-0575-z\">published<\/a> in Nature Energy (2020), where researchers proposed using a silver-carbon (Ag-C) composite layer as the anode in an all-solid-state pouch cell, a first in the field. The Ag-C nanocomposite layer, just 5 \u00b5m thick, enabled the team to reduce the anode volume, increase the energy density to up to 900 Wh\/L, and make the prototype approximately 50% smaller in volume than a conventional lithium-ion battery.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This design also directly addresses dendrite formation, which is one of the most persistent failure modes in lithium metal batteries. As a result, it extends cycle life to over 1,000 full charges without significant capacity degradation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Samsung SDI&#8217;s current ASB (All-Solid-State Battery) development uses a proprietary solid electrolyte material combined with anode-less technology, which removes the anode layer volume entirely to accommodate more cathode material.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"860\" height=\"538\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-21.png\" alt=\"image\" class=\"wp-image-111382\" srcset=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-21.png 860w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-21-300x188.png 300w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-21-150x94.png 150w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-21-768x480.png 768w\" sizes=\"(max-width: 860px) 100vw, 860px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This design removes the need for a separator, further increasing volumetric energy density. The company has already demonstrated a 900 Wh\/L target under laboratory conditions. It nearly doubles the energy density of mainstream EV batteries, which are approximately 500 Wh\/kg.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Electrolyte Breakthrough<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In February 2026, Samsung SDI, in collaboration with SDI R&amp;D America and Columbia University, <a href=\"https:\/\/www.samsungsdi.com\/sdi-now\/sdi-news\/4742.html\">announced<\/a> a breakthrough in lithium-metal battery technology. The battery system uses a fluorine-based gel polymer electrolyte that effectively suppresses dendrite formation, extends battery lifespan, and improves safety. This hybrid electrolyte approach bridges the gap between liquid and solid electrolytes and may serve as the critical enabling step toward the commercialization of next-generation lithium-metal cells.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>\u201cThis study represents a major improvement in lithium-ion battery performance through a new electrolyte formulation and brings commercialization of next-generation batteries one step closer,\u201d<\/em> said Professor Yuan Yang of Columbia University.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Commercialization Timeline<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Samsung SDI plans to complete mass production preparations for all-solid-state batteries by 2027. It targets the <a href=\"https:\/\/www.mk.co.kr\/en\/economy\/11986326\">robotics market<\/a> rather than EVs for its solid-state batteries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>&#8220;All-solid battery is an innovative solution that can increase the robot&#8217;s operating time by up to eight hours with high capacity,&#8221;<\/em> said Samsung SDI&#8217;s strategic marketing executive director Lim Sang-seok, at the Interbattery 2026 conference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. CATL<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CATL is the world&#8217;s largest EV battery manufacturer, with nearly 40% of the global market share. It <a href=\"https:\/\/insights.greyb.com\/catl-patents\/\">holds<\/a> more than 32,000 patents globally. Its solid-state battery program, internally called &#8220;Ningde Shidai All-Solid-State,&#8221; is one of the most well-funded and patent-active SSB R&amp;D programs in the world, backed by $2.59 billion in R&amp;D spending in 2024.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike Toyota&#8217;s LGPS-based and Samsung SDI&#8217;s Ag-C approaches, CATL has doubled down on sulfide-based solid electrolytes, specifically argyrodite-type crystal structures, which offer superior ionic conductivity at room temperature.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CATL&#8217;s latest international patent (PCT\/CN2025\/086345, published March 5, 2026) details a fluorine-containing lithium salt combined with sulfide solid-state electrolyte materials.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fluorine-based additive provides high-temperature stability and, upon decomposition, generates lithium fluoride (LiF), which forms an in situ protective solid-electrolyte interphase (SEI) layer on the cathode\u2014acting as a shield to stabilize the electrolyte, suppress dendrite growth, and extend cycle life.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lithium Metal Battery Breakthrough<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In 2025, CATL&#8217;s dedicated next-generation research unit, the 21C Lab, <a href=\"https:\/\/www.nature.com\/articles\/s41565-025-01935-y\">published<\/a> a breakthrough in lithium-metal battery electrolyte formulation. By introducing a lower-molecular-weight diluent and increasing the LiFSI (lithium bis(fluorosulfonyl)imide) salt mass fraction, the team simultaneously improved ionic conductivity and reduced electrolyte viscosity.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"685\" height=\"736\" src=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-22.png\" alt=\"image\" class=\"wp-image-111383\" srcset=\"https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-22.png 685w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-22-279x300.png 279w, https:\/\/greyb.com\/wp-content\/uploads\/2026\/01\/image-22-140x150.png 140w\" sizes=\"(max-width: 685px) 100vw, 685px\" \/><figcaption class=\"wp-element-caption\">Source: Nature<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The resulting prototype achieved 483 charge-discharge cycles, which is double the lifespan of the previous iteration.
