BMW partners with Solid Power on solid-state batteries
BMW is partnering with US battery developer Solid Power to utilise its knowledge of solid-state cells as the German automaker develops its electric vehicles. Solid-state batteries offer greater energy density in comparison with lithium-ion batteries, meaning increased driving range, accelerated charging rates and increased safety.
BMW is jumping into the solid-state battery game and it's doing so by teaming up with battery-developer Solid Power. The company is a spin-out from the University of Colorado Boulder and has been developing solid-state rechargeable batteries since 2012. BMW is partnering with Solid Power to bring its battery technology to electric vehicles. "Since the company's inception, the Solid Power team has worked to develop and scale a competitive solid-state battery paying special attention to safety, performance and cost," Doug Campbell, founder and CEO of Solid Power, said in a statement. "Collaborating with BMW is further validation that solid-state battery innovations will continue to improve electric vehicles."

Solid-state batteries offer a few advantages over the lithium-ion batteries largely in use today including greater energy density and, therefore, increased driving range when used in EVs, less chance of fire or explosion and rapid recharging. The benefits of solid-state batteries are why so many companies, including Fisker, Toyota and Google, are looking to develop the technology and ultimately incorporate them into their products.

Batteries that limit EVs' driving ranges will certainly keep these types of vehicles from becoming mainstream. So technology that can stretch those driving distances and make EVs as convenient as traditional gas-powered cars will be a must when it comes to expanding their use and, therefore, the environmental benefits they afford.
