Solid-state batteries are becoming a technological high ground for various car companies.
In the field of solid-state batteries, Toyota has a globally recognized leading advantage. Public information shows that Toyota currently has more than 1,000 patents related to solid-state batteries.
Recently, according to media reports, Toyota Motor will launch a solid-state battery in 2021, which can provide 500 kilometers of battery life.
Solid-state batteries are very different from lithium-ion batteries. Solid-state batteries are batteries that use solid electrodes and solid electrolytes. The energy density is twice that of lithium-ion batteries.
According to Toyota officials, the solid-state battery is expected to be a viable alternative to lithium-ion batteries using aqueous electrolyte solutions. This battery can be charged from empty to full within 10 minutes, and has minimal safety hazards. The charging speed is close to that of traditional fuel vehicles.
Toyota officials stated that for electric vehicles that use traditional lithium-ion batteries, this technology is a potential universal solution that can greatly reduce the time required for a full charge.
Market participants believe that if the solid-state battery is safe enough, its safety should be emphasized. Regarding fast charging, this is not the bright spot that solid-state batteries should have, and the battery life of 500 kilometers is not excellent.
In terms of supporting new energy vehicles, Although Toyota announced the solid-state battery this year, prototype vehicles equipped with the solid-state battery will not be launched until 2022. And, according to Toyota’s It is planned that its mass production time will be around 2025.
In the current domestic market, NIO has also announced that it will mass-produce semi-solid batteries, and the vehicle life will exceed 1,000 kilometers. However, at present, the battery is also a futures product, and it will be released in the fourth quarter of 2022 at the earliest.
