# Batteries: Chinese automakers accelerate integration and solid-state technologies > In China, several automakers are accelerating in-house battery development, disrupting the sector balance dominated by large manufacturers like CATL. Geely plans trials for semi-solid packs announced with up to 1,000 km of range and capable of supporting 1 MW charging, while GAC announces its first solid-state batteries before the end of the year and BYD reaches full production of its Blade batteries in Shaanxi. Strategies diverge, however: IM Motors strengthens its supply partnership, while one automaker faces difficulties with its in-house developed batteries, illustrating the risks of vertical integration. The available sub-events focus on China; coverage of the topic in Italy and Brazil provides no documented national difference. **In brief**: Ongoing story bringing together 10 events involving CATL, Geely, GAC Group and 4 more, in Chine, followed from 31 October 2026 to 3 November 2026. 18 articles from 6 sources (electric and batteries, plants, jobs and earnings);
