# Solid-state batteries: China accelerates, CATL dominates global market > Chinese automakers and manufacturers are accelerating the development of solid-state and semi-solid batteries, with pilot production validations, announced ranges of up to 1,000 to 1,500 km and charging of up to 1 MW. CATL expects, according to an analysis note, small-series production of solid-state cells as early as 2027, while several Chinese automakers develop their own batteries while remaining dependent on CATL. Globally, CATL is strengthening its dominance of the electric vehicle battery market and the combined share of the three South Korean manufacturers is declining. Coverage of the dossier extends to Italy and Brazil, but the provided sub-events do not detail any national difference specific to these markets. **In brief**: Ongoing story bringing together 17
