In general, vehicles with solid-state batteries as standard were not expected until the middle of this decade. Mercedes-Benz is faster: the new eCitaro G is the first series production city bus in its category anywhere in the world to be equipped with solid-state batteries. They have a very high energy density which is around 25 percent greater than the coming generation of traditional lithium-ion batteries with liquid electrolyte. The result is an impressive energy content of 441 kWh for the new eCitaro G. This battery technology is also free of the chemical element cobalt and therefore especially environmentally friendly in the manufacture of the components.

The long life of the solid-state batteries is particularly striking. Therefore, when purchasing an eCitaro with solid-state batteries, a basic guarantee for the high-voltage battery for up to 10 years or up to 280 MWh energy throughput per battery pack is standard.
