JAKARTA - A battery manufacturer from China, Contemporary Amperex Technology Co. Limited (CATL), confirmed its position as an absolute leader in the global electric vehicle (EV) battery market.

According to the latest data from South Korean market research firm SNE Research, quoted from CnEVPost, Tuesday, December 2, in the period January to October 2025, CATL managed to reap a market share of 38.1 percent. This figure further increases their dominance, making CATL the only battery supplier that has managed to surpass 30 percent of the world's market share.

Global EV battery market performance itself shows significant growth. The total global EV battery installations reached 933.5 GWh during the first 10 months of 2025. This figure jumped sharply, up by 35.2 percent compared to the same period last year which was recorded at 690.7 GWh. CATL personally also recorded impressive installation growth of 36.6 percent year-on-year, reaching 355.2 GWh.

In second place, fellow Chinese giant BYD helped strengthen the country's hegemony by controlling 16.9 percent of the market share. Together, CATL and BYD have collectively installed 513.1 GWh EV batteries, meaning they control more than half of the market, to be precise 55.0 percent of the global total. However, BYD's market share declined slightly from the January-September 2025 period which reached 17.9 percent, although their installation grew 36.1 percent on an annual basis.

Competition outside the top two shows an interesting turmoil. South Korea's LG Energy Solution, which is a key player, managed to maintain its third position even though its market share continued to be depressed, down to 9.3 percent (from 11.1 percent the previous year). Meanwhile, another Chinese company, CALB, occupies fourth place with 4.7 percent market share. The most significant change was seen in fifth place, where Higher-tech managed to overtake SK On South Korea, securing 4.1 percent share, driven by strong growth.

With total battery installations soaring more than a third, the global EV market continues to be a major battleground for East Asian battery suppliers. China's dominance, led by CATL and BYD, looks even stronger and threatens the position of Korean and Japanese producers in the market. The dynamic shift in rankings, particularly in the top 5-10 lineup, indicates that innovation and aggressive strategies are key to surviving and developing in this rapidly evolving industry.
