# EV Batteries: CATL Dominates, China Accelerates in Solid-State > CATL is strengthening its dominance in the global electric vehicle battery market, while the combined share of the three Korean manufacturers declines. In China, automakers and suppliers are multiplying announcements and validations regarding solid-state and semi-solid-state batteries, with pilot production or small-series horizons around 2027, and several groups seeking to develop their own batteries while remaining linked to CATL. This trend applies to the entire market, with solid-state batteries presented as the next technological step for EV range and costs. Visible national differences mainly concern China, the driver of industrial announcements, and South Korea, whose manufacturers are experiencing a decline in their global market share. **In brief**:
