固态电池通过将液体电解质替换为固体陶瓷或聚合物材料，相比传统锂离子电池实现了更快充电、更长续航和更高安全性能 1。这一新一代电池技术正在由全球多家企业推进商业化进程。
QuantumScape在2025年宣布了固态电池陶瓷电解质的大规模专有制造方法，将烧制时间从数天缩短至数分钟 1。丰田与Idemitsu Kosan合作试点工厂，承诺电动汽车充电10分钟内可行驶745英里 1。CATL在2024年向固态电池研发项目投入近26亿美元 1。梅赛德斯在去年秋季为EQS轿车配备固态电池，续航750英里后仍有剩余范围 1。
行业预期固态电池成本将在2030年代中期与锂离子电池相当 1，这将大幅提升其在消费市场的竞争力。
Solid-state batteries are advancing toward mass production as leading automotive and battery manufacturers pursue commercialization of the technology, which replaces liquid electrolytes with solid ceramic or polymer materials to achieve faster charging, extended range, and improved safety compared to conventional lithium-ion batteries 1.
QuantumScape announced in 2025 a proprietary large-scale manufacturing method for solid-state battery ceramic electrolytes, reducing firing time from several days to just minutes 1. Toyota and Idemitsu Kosan are operating a pilot factory with the goal of enabling electric vehicles to travel 745 miles on a 10-minute charge 1. Mercedes-Benz equipped the EQS sedan with solid-state batteries last autumn, with testing showing remaining range even after 750 miles of driving 1. CATL invested nearly $2.6 billion in solid-state battery research and development in 2024, a significant commitment from the company that controls approximately 40 percent of the global battery market 1.
Industry projections indicate that solid-state battery costs will reach parity with lithium-ion batteries by the mid-2030s 1.
