We're expecting traditional lithium-ion batteries to pave the way for a transition to solid-state in EVs during the next couple of years, but before then it seems that a new type of chemistry within the traditional battery framework has a lot more to give.
FAW Group (through a range of Chinese media), one of China's largest automotive manufacturers, have presented a new lithium-manganese chemistry, which isn't truly solid-state, but still apparently manages to give a specific prototype over 1,000 kilometres of range.
This was tested in a Honqi crossover, and in this particular vehicle there are some wild stats. We're talking a 142 kilowatt battery, which manages a density of 500 watt-hours per kilogram on the battery cell-level.
The more realistic range estimates would probably be lower, as this is just the rated WLTP of the battery, not the car, but it's still impressive stuff.
