Chinese companies are green. Everyone else is red. The gap isn’t narrowing — it’s accelerating.
2. CATL: Pulling Away
CATL’s 40.2% is up from 38.0% YoY. Growing 22.9% in a 16.3% market — defying the rule that leaders grow slower. Annualized ~450 GWh, more than LG + BYD + CALB combined. The strategy: dominate production → own the standards with BMW, Google, Xiaomi → license the tech to Ford in Michigan.
3. BYD: The Anomaly
Share dropped 16.7%→14.4%. Installations +0.4%. Paradox: world’s second-largest battery maker, also a CATL customer (buying batteries for export models). Facing the same domestic market slowdown as everyone else. The gap with CATL widened from 21.3pp to 25.8pp.
4. The Real Story: China’s Tier 2
CALB +36.3%. Gotion +37.0%. Eve +35.2%. Svolt +35.3%. Their combined 84.4 GWh exceeds LG + SK On (56.8 GWh). Not startups — CALB supplies XPeng/Nio/Leapmotor, Gotion backed by VW.
Meanwhile: Panasonic -8.5% (3.2% vs 4.1% a year ago). SK On -5.8%. The Korean and Japanese industry isn’t losing to CATL alone — it’s being surrounded by a wave of Chinese Tier 2 growing at 35%+.
Author’s Take: Four years ago, LG briefly led CATL. Today, CATL is 4.6x larger. Three years ago, Panasonic was top 3. Today, eighth and shrinking. Chinese Tier 2 growing 35%+ while rivals flat or contracting. This is not a race. It’s a rout. China already controls the global battery industry. The question is whether anyone outside China can survive.
The Bottom Line
Global EV battery market share: CATL 40.2% and widening. Seven Chinese firms at 72.6%. All three non-Chinese top-10 names lost share. Chinese Tier 2 growing 35-37%. The combined Chinese share will cross 80% within two years.
[…] Japan and South Korea still hold strong core patents, particularly Toyota, with roughly 1,800 patent families in the field. Toyota’s commercialization has slipped repeatedly, but the intellectual-property position means China leads on volume and standards while rivals retain leverage on foundational chemistry.
