Korean EV Battery Makers Lose Ground to Chinese Rivals.

Korea's three major eectric-car battery makers are losing ground to their Chinese rivals such as BYD and CATL.

Their combined share of the global EV battery market fell about nine percentage points on-year from January to May.

Korean battery makers' global sales grew from last year, with LG Energy Solution selling 22.6 gigawatt-hours of batteries in the first five months, up 7.9 percent on-year

SK On sold 10.8 GWh of batteries, more than doubling from 4.7 GWh, and Samsung SDI 6.9 GWh, up from 5.2 GWh.

But their market share dropped

because Chinese companies are growing so rapidly.

CATL's EV battery sales more than doubled from 25.1 GWh a year ago to 53.5 GWh

BYD's sales grew from 6.1 GWh to  19 GWh.
