Scientists all over the world are arduous at work on solid-state batteries, which may provide important technical and security benefits over present lithium-ion designs. Nonetheless, whereas micro-solid-state batteries are already in business use in some purposes, most specialists consider that large-scale automotive solid-state batteries are nonetheless years away from commercialization.
Apparently, Mercedes didn’t get the memo, as a result of the corporate is already utilizing solid-state battery tech in a brand new model of its eCitaro electrical transit bus.
“Typically, autos with solid-state batteries as customary weren’t anticipated till the center of this decade,” says the corporate. “Mercedes-Benz is quicker: the brand new eCitaro G is the primary collection manufacturing metropolis bus in its class wherever on the planet to be outfitted with solid-state batteries.”
Mercedes will make its articulated eCitaro G buses out there with optionally available solid-state batteries as a substitute for conventional lithium-ion batteries. The corporate says the solid-state batteries ship an extended service life and a 25% enchancment in power density in comparison with the newest Li-ion cells.
Within the eCitaro G, the solid-state cells make up a battery pack (divided into 5 roof-mounted modules) with a capability of 441 kWh, in comparison with 396 kWh for a lithium-ion pack. Vary is estimated at 136 miles in common situations, or 105 miles in winter with the heater operating, an enchancment of roughly 10 p.c in comparison with the Li-ion choice. The solid-state pack can also be anticipated to have an extended lifespan—Mercedes warranties the solid-state battery pack for 10 years, or 280 MWh of power throughput.
There’s a trade-off, nevertheless. In line with Mercedes, its solid-state batteries are “restricted of their fast-charging capability” in comparison with its Li-ion battery pack choice.
