Geely developed a battery that can ensure driving of one million kilometers

Zhejiang Geely Holding Group, commonly known as Geely Holding, has produced a battery that can ensure driving of one million kilometers with minimal impact on range, and retains more than 90 percent of its capacity at temperatures below -30 degrees Celsius. It is an LFP (lithium-iron-phosphate) battery with a density of 192 Wh/kg.

The new battery charges faster and takes 17 minutes and 4 seconds to charge from 10 to 80 percent. It also manages to retain 90.54 percent of its capacity at a temperature of -30 degrees Celsius, and can be charged up to 3,500 times. The secret is in its construction. It contains doped electrode materials in its composition in order to reduce the speed of the internal chemical reaction.

Geely tested the battery with a large number of tests, including the extreme ones. They pierced the battery with eight 5 mm steel needles and left it in that condition for an hour. Next, a 5.8 mm round was fired into the battery and failed to ignite it. After that, it was submerged in seawater, thrown into a fire, and even run over with a 26-ton roller. None of the tests caused significant damage.

This would definitely be a revolution in the development of batteries, and the company did not announce when production would start.
