South Korean battery professional Park Chul-wan reported the picture may perhaps hint at “silicon nanowire anode,” a breakthrough technology which can perhaps improve the two battery vitality density and battery life sharply.

Panasonic Corp earlier explained to Reuters that it options to increase the electrical power density of the first “2170” battery cells it materials to Tesla by 20% in 5 a long time.
