Toyota is preparing a new generation of solid-state batteries, which will be rebuilt this year


Solid-state batteries are said to be the successor to today’s Li-ion batteries.

Solid-state batteries of a new generation have to bring shorter charging time, longer range and higher energy density. Toyota reportedly plans to present the premiere of a prototype of such a battery later this year.

However, it is uncertain whether this will really happen. Toyota has long avoided battery electromobility. She announced in 2022 that she would introduce an electric car with solid-state batteries even in 2017. Only a year later, however, she began to claim that solid-state batteries were still 10 years away.

According to studies, the breakthrough technology of solid electrolyte batteries has the potential to revolutionize the automotive industry. In electric cars, it is to replace today’s lithium-ion batteries.

The change will bring numerous benefits to users. Charging is speeded up, the range is extended and the battery should also be safer. That is why other carmakers are investing in solid-state batteries.

Volkswagen has invested considerable money in the QuantumScape start-up supported by Bill Gates. Ford and BMW again invested in Solid Power.

However, the information that solid-state batteries are also used in practice is absolutely crucial. This is in the Mercedes-Benz eCitaro G articulated electric bus. This is the second generation of NMC (Nickel-Manganese-Cobalt) batteries.

In these batteries, the anode is made of graphite with pure lithium and the cathode of lithium iron phosphate (LiFePO4). Thanks to higher energy density The MB eCitaro G electric bus can have a battery capacity of up to 441 kWh (7 x 63 kWh).
