CATL Approaches 30% Market Share Outside China as Korean Battery Makers Drop 6.8% Points

Chinese secondary battery company CATL has achieved a market share of nearly 30% in the global electric vehicle battery market outside of China. Although domestic battery companies also recorded growth, their combined market share fell by 6.8 percentage points.

According to SNE Research, a secondary battery market research firm, the total battery usage installed in global electric vehicles (excluding China)-including battery electric vehicles, plug-in hybrid vehicles, and hybrid vehicles-sold from January to November 2025 reached approximately 415.1 GWh (gigawatt-hours), representing a 26.4% increase compared to the same period the previous year.

During this period, the combined market share of the three major domestic battery companies-LG Energy Solution, SK On, and Samsung SDI-fell by 6.8 percentage points year-on-year to 37.2%.

LG Energy Solution maintained its second-place position with 7.7% growth year-on-year, but its market share declined by 3.7 percentage points to 20.9%. SK On retained third place with a market share of 9.7%. In contrast, Samsung SDI saw its battery installation volume decrease by 4.9%, and its market share dropped to sixth place.

In the global market excluding China, CATL maintained its top position with 37.5% year-on-year growth. Its market share reached 29.2%, approaching the 30% mark. BYD ranked fifth, recording a growth rate of 138.0% in markets outside China.

SNE Research stated, "In North America, the slowdown in electric vehicle growth is leading automakers to strengthen long-term procurement contracts and restructure local supply chains. While energy storage systems (ESS) will partially offset this, the transition of ternary facilities to prismatic lithium iron phosphate (LFP) will be influenced by cost and time factors."
