As we all know, at present, pure electric vehicles mainly use lithium-ion batteries, which need liquid electrolyte solution, but this technology may reach its limit in the current development. In contrast, the core of solid-state battery is solid electrolyte, which greatly reduces the fire risk, doubles the energy density, is not easily affected by extreme temperature, and has the advantages of lighter weight and longer service life.
The announcement that Toyota will release solid-state batteries seems well prepared. It is reported that Toyota has more than 65,438+0,000 patents in the field of solid-state batteries, ranking among the top in the world. Other Japanese car companies also have this layout. It is reported that Nissan also plans to build its own solid-state battery car, hoping to launch a real car before 2028. Toyota plans to become the first company in the world to sell solid-state battery cars in the early 1920s.
However, according to Toyota insiders, at present, the durability and safety of solid-state batteries still need to be improved, and of course the cost will be high. Toyota engineers are adjusting anodes and other materials, especially solid electrolytes. At the same time, we hope to solve the cost problem of solid-state batteries before 2025, and the future cost needs to be lower than 100 USD/kWh to compete with fuel engines.
At the same time, Toyota hopes to produce solid-state batteries that can be used for more than 30 years and still maintain more than 90% initial performance. In the future, Toyota will promote the development of solid-state battery business through Taixing, a joint venture with Panasonic.
