No, that is incorrect PANASONIC Corp. is the market leader in the manufacturing of batteries, BYD comes close second
(I say close since the BYD electric bus battery operation is not in the graph). Buffet invested because at that time the SP was HK$ 13 in Dec 2008 when he took the 10% position, which still is over its current Graham Nr. of HK$ 7,69. BYD's SP is currrently HK$ 44,6 meaning that it is extremly overvalued.

As of 2013 commercial specific energies for supercapacitators range from around 0.5 to 15 Wh/kg. For comparison, an aluminum electrolytic capacitor stores typically 0.01 to 0.3 Wh/kg, while a conventional
lead-acid battery stores typically 30 to 40 Wh/kg and modern
lithium-ion batteries 100 to 265 Wh/kg. Supercapacitors can therefore store 10 to 100 times more energy than electrolytic capacitors, but only one tenth as much as batteries. The supercapacitators in the 10-15 Wh/kg are Li-Ion capacitators.
