Batteries That Last Far Longer Than Today’s Batteries
But Not for EVs This Year, Nor Next, Nor the Year After…
Colorado’s Solid Power is developing solid-state lithium batteries with the potential for energy density nearly double that of the batteries available today. Just don’t expect them anytime soon.
The potential is for batteries able to store 350 or even 500 watt-hours of electricity per kilogram, says Solid Power CEO Doug Campbell up from about 270 watt-hours per kilo today.
“We want to revolutionize the market,” he says.
Cheaper, Lighter, All of That
Faced today with trading performance for safety, “Solid-state batteries are the answer that manufacturers like General Motors and Hyundai are looking for,” says a Solid Power spokesman. “Solid-state batteries can hold more energy in smaller, lighter packages – cutting the cost and weight of EVs in addition to being far less flammable.”
“Our technology,” says the company, “is based on combining an exceptionally high capacity cathode with a high capacity lithium metal anode and in combination with a high ionic conductivity solid separator.
Simpler Battery Systems
“Our battery materials are 100% inorganic and possess no flammable or volatile components,” the firm adds.
They offer two to three times the energy capacity of conventional lithium ion batteries, “while also enabling lower cost systems due to the potential for eliminating many of the costly safety features typically associated with lithium ion systems.”
But, “We’re still a number of years away from the technology being integrated into a vehicle,” says CEO Campbell.
‘A Five- to Ten-Year Horizon’
“This is a about a five- to ten-year horizon,” he says.
But “the value proposition is so strong,” Campbell told F&F, that “auto OEMs are getting involved today.”
