Nokia BL-4C 950mAh Li-ion Battery

Product Information

The new LFP battery will enable up to 434 miles (700 km) range. CATL claims its new innovation is the world’s first LFP battery to support 4C charging, as well as a “battery for everyone.” For those that don’t know, the “C” refers to the charging multiplier of the battery. Hence 4C can charge in a quarter of an hour.

Note – Batteries with a higher C rating will usually be slightly heavier, than others with the same voltage and capacity. CATL says its new fast-charging battery solves these issues. It’s new LFP battery “embodies the perfect balance of long range and easy refueling.” Cheeseman, H. Fast-charging Li-metal batteries. ARPA-E https://arpa-e.energy.gov/open-2021/webinars (2021). The company chose the name Shenxing (an ancient Chinese phrase praising speed) to represent its goal of creating value for ordinary people as it strives to bring it to market at extreme speed.

So if they can do 4C it's only for the first few minutes. Existing EVs, e.g. Model 3/Y and Lucid Air can do ~3C for a few minutes. This is an improvement, but not a quantum leap.
