Battery sector charges ahead for superior tech

China’s power battery sector is expanding rapidly, driven by strong demand for new energy vehicles (NEVs). In 2023, the country installed 387 gigawatt-hours of batteries, over half of the global total, with CATL, BYD, and CALB as the top three suppliers. From January to April 2024, installations grew 32.6% year-on-year to 120.6 GWh, while NEV production is projected to rise 31.9% to 10.83 million units, with battery installations expected to hit 527 GWh—a 35.9% increase. A key factor in China’s success is its dual approach to battery technology, developing both lithium iron phosphate (LFP) and ternary lithium batteries. LFP batteries dominated first-quarter installations at 79.8 GWh (66.1% share), up 28.6%, while ternary batteries grew 41.2% to 40.8 GWh. CATL’s Shenxing Plus LFP battery, unveiled at the Beijing auto show, offers 1,000 km range or 600 km after a 10-minute charge. Solid-state batteries are seen as the next breakthrough, offering higher energy density, safety, and longevity. Gotion High-Tech plans small-scale production by 2027 and mass production by 2030 for its all-solid-state battery. Meanwhile, semi-solid-state batteries are already in use, such as in SAIC’s IM Motors L6 sedan, which achieves 400 km range in 12 minutes with a 400 kW charging system. Industry experts, including academician Ouyang Minggao, highlight solid-state batteries as critical for next-gen competition. Challenges in durability and safety remain, but semi-solid-state solutions like Nio’s ET7—tested for 1,044 km on a single charge—demonstrate progress. China’s dual-track strategy and technological advancements position it to lead the global battery market.
