宁德时代

<p>宁德时代在固态电池开发方面取得了重大进展，获得了一项新专利并确保了大量铜箔供应。该专利专注于固态硫化物电解质，目标能量密度为 500 Wh/kg。宁德时代计划到 2027 年生产一小系列这些电池，目前已开始试生产。公司已预留 62.6 万吨铜箔用于未来的规模化生产，价值 84 亿欧元。此外，宁德时代还参与了一个财团，以加速固态电池在中国的商业化，强调了中国在电动汽车电池技术方面保持领先地位的承诺</p>

<p>For years, CATL has been working towards producing a small series of solid-state batteries by 2027. A new patent now reveals how the Chinese battery giant plans to achieve this. The document was published on 5 March 2026 by the World Intellectual Property Organisation (WIPO) and is titled ‘Positive Electrode Sheet, Solid-State Battery Cell, Battery Device, Electric Device, Positive Electrode Active Material and Preparation Method Therefor.’</p>

</div><p>The patent summary indicates that CATL is focusing on a solid sulfide electrolyte. The anode active material comprises layers of a substrate material, a cobalt-rich material, and a coating. The first two layers contain a transition metal oxide, while the coating includes an electrolyte salt. According to the portal Electrek, this salt is a fluorine-containing lithium salt, which offers high thermal stability and can react with the sulfide electrolyte to form lithium fluoride. This reaction is intended to create a protective layer for the battery anode, mitigating the known instability of sulfide electrolytes.</p>

</div><p>While the patent itself does not include a timeline, the portal <em>CarNewsChina</em> reports that CATL has already begun pilot production of solid-state batteries with an energy density of 500 Wh/kg. Furthermore, ‘technical data indicates the company is currently at technology maturity level 4 and aims to reach levels 7 or 8 by 2027. This level signifies the transition from laboratory prototypes to automotive-grade cells ready for pilot-scale vehicle integration,’ the portal states. This aligns with the company’s goal of launching a small series by 2027, as well as China’s announcement that it will publish its first national technical standard for solid-state batteries in July this year.</p>

</div><p>CATL plans to introduce its battery, named Ningde Shidai All-Solid-State, without delay. The company’s short-term goal is to progress from 20-Ah samples to 60-Ah automotive-grade prototypes. Ah stands for ampere-hour, a measure of charging capacity. Meanwhile, CATL appears to be securing supplier services for future scaling. <em>CarNewsChina</em> reports that CATL recently reserved a capacity of 626,000 tonnes of copper foil from Guangdong Jiayuan Technology for the period 2026–2028, valued at approximately €8.4 billion. The portal interprets this as a significant material stockpile for semi-solid and solid-state batteries.</p>

</div><p>However, in October 2025, CATL dialled down expectations, stating that ‘scientific challenges have been largely resolved,’ but technical hurdles remained. Cost was a primary concern. “Sulfide solid-state cells are currently 3–5 times more expensive than conventional lithium-ion,” according to <em>CarNewsChina</em>.</p>

</div><p>Speaking of collaborations: In early 2024, it was announced that a group of major Chinese battery and automotive manufacturers had joined forces to accelerate the commercialisation of solid-state batteries. CATL is among them. The alliance was initiated by the Chinese government, and the consortium, named the China All-Solid-State Battery Collaborative Innovation Platform (CASIP), aims to develop and produce competitive solid-state batteries and establish a supply chain by 2030.</p>
