Toyota's Solid-State Battery Prototype Could Be an EV Game Changer

Imagine an electric car battery that provides more than 300 miles of range, charges in approximately ten minutes, requires no bulky heating and cooling systems, maintains 80 percent of its charge capacity for 800 cycles (about 240,000 miles), and isn't prone to spontaneous combustion. Such is the promise of the solid-state car battery, a holy grail that automakers and manufacturers are racing to find. Now, Toyota announced it'll have a running prototype with a solid-state battery ready by next year.

Toyota is far from the sole entrant in this race, nor is it the only company making headlines. Last week, a California company called QuantumScape, which has a strategic partnership with Volkswagen, announced promising test results for its own solid-state cell. Toyota's announcement of its upcoming Euro-market electric SUV included the note that the company plans to have solid-state battery technology in its production vehicles by 2025.

Needless to say, other companies are well into the race. Samsung has developed a solid-state battery using silver-carbon instead of lithium. This prototype battery has the potential for 500 miles of range in a pack half the size of a modern lithium-ion battery. Additionally, Colorado-based Solid Power is partnering with Ford and BMW to develop battery tech, while Mercedes is working with Hydro-Québec in Canada.

The race to develop a solid-state battery for electric vehicles is on, and if Toyota's plans to produce a running prototype in 2021 come to fruition, then we could very well be looking at the dominant automotive technology of the future within the next year.
