CATL Leads Global ESS Battery Market as Non-China Regions Gain Ground
In the first half of 2026, CATL maintained its leadership in the global energy storage system (ESS) battery market with a 27.1% share, according to SNE Research. The market is witnessing a shift as non-China regions, including North America and Europe, are overtaking China in terms of market share. Residential storage saw the fastest growth, with shipments increasing by 128% to 47.7 GWh. The report highlights that supply chain stability, local production capacity, and regulatory compliance are becoming crucial factors in supplier selection, alongside price competitiveness. This shift is driven by tightening tariffs and supply chain rules on Chinese-made batteries in North America and Europe.
