Panasonic has already suspended production at two lithium ion battery factories in Japan and will cancel expansion plans for a new plant, the paper said.

The company plans to ramp up production in China to 50 percent of total lithium ion batteries in three to four years from 10-20 percent currently, the Nikkei said.

Panasonic expects to slash up to 30 percent of production cost to help its battery business — which generates some 300 billion yen ($3.93 billion) in annual sales — compete with Korean companies that are rapidly expanding their market share, the paper reported.
