Solid-state battery technology is increasingly being touted as the next big step in the development of electric vehicles, but the latest estimates indicate that its market penetration will be much slower than expected.
According to Ouyang Minggao, an academician of the Chinese Academy of Sciences and a professor at Tsinghua University, this technology will take between five and ten years to reach just 1% market share.
The battery with a solid electrolyte is just entering the application phase
Although it is expected that the first installation in vehicles will begin around 2027, this does not mean rapid commercialization. Test vehicles with this technology should appear already at the end of 2026 or during 2027, but mass production depends on further development and an increase in production capacity.
The key advantage of batteries with a solid electrolyte lies in their higher energy density compared to classic lithium-ion batteries, which currently reach around 300 Wh/kg. Some manufacturers are already announcing significantly higher values, but the technology is still not ready for widespread use.
Major companies such as Toyota and Nissan are developing their own solutions in parallel, with Toyota targeting lower production around 2026 and higher volume after 2030.
The main problems are still of a technical nature: high contact resistance between solid materials, formation of lithium dendrites and a limited number of charge and discharge cycles. In addition, the cost of production remains high, and without a large volume of production, there is no significant drop in costs.
Although often presented as a revolutionary solution, the battery with a solid electrolyte is still in the early stages of development. Getting into vehicles is just the first step, while the actual market breakthrough will obviously take much longer, reports CarNewsChina.
