China Mar Power Battery Installations Flat as Production Surges 50%

Key Takeaways

• March installations 56.5 GWh, flat YoY but +115% MoM
• Production hit 177.7 GWh, up 50% YoY
• LFP batteries 81% of installs, still dominant
• Energy‑storage sales surged 116% YoY, boosting exports
• Exports rose to 36.1 GWh, +57% YoY

Pulse Analysis

China’s battery sector entered March with a paradox: installations barely moved, yet production exploded. The 177.7 GWh output—up 50% year‑over‑year—reflects aggressive capacity expansions by CATL, BYD and a wave of new entrants responding to supportive government subsidies and the accelerating rollout of electric vehicles. While domestic demand momentarily plateaued after the February holiday lull, manufacturers leveraged the excess capacity to stockpile inventory and fulfill burgeoning overseas orders, cushioning the market from a potential supply crunch.

Lithium‑iron‑phosphate (LFP) remains the chemistry of choice, accounting for 81% of March installations. Its safety profile, lower cost and compatibility with Chinese automakers’ vehicle platforms keep it ahead of ternary lithium, which grew modestly but showed a healthy 7% year‑over‑year increase. The chemistry mix signals a strategic tilt toward cost‑effective, long‑life solutions for both passenger EVs and grid‑scale storage, while premium models continue to demand higher‑energy ternary cells. This balance influences raw‑material demand, with lithium‑iron‑phosphate’s iron and phosphate needs rising faster than cobalt‑rich ternary supplies.

Export momentum amplified China’s global footprint: March shipments reached 36.1 GWh, a 57% jump, and now represent over one‑fifth of domestic sales. The surge bolsters CATL’s 42% share of the worldwide market and BYD’s 13% stake, together holding more than half of global capacity. As Western automakers scramble for reliable supply, China’s ability to scale production while keeping costs low could reshape pricing benchmarks and accelerate the transition to electric mobility worldwide.
