CATL chairman Robin Zeng warned at the 2026 World Power Battery Conference in Yibin on September 3, 2026 that China's compressed vehicle development schedules and intense price competition are contributing to batch-level power battery quality failures. Zeng said more than 600 new vehicle models have launched in China in 2026, roughly three a day, and argued that conventional parts-per-million defect tolerances are no longer adequate at that volume, citing CATL's own internal target of one defect per billion cells. He did not name the affected automakers or battery suppliers.
