Energy Storage Manufacturers in China: The Global Powerhouse Driving ESS Innovation

As the world accelerates toward renewable energy adoption, China has emerged as the undisputed leader in energy storage manufacturing, accounting for 63% of global ESS production capacity in Q1 2025. At Voltsmile, we’ve collaborated with China’s top-tier manufacturers to deliver cutting-edge solutions that combine scale, innovation, and cost-efficiency.

1. China’s Dominance in Energy Storage Manufacturing

Unmatched Production Capacity

China’s energy storage manufacturing ecosystem now boasts:

• 14 GWh/month lithium-ion battery production (58% global share)
• $2.8 billion quarterly investment in new production lines
• 92% vertical integration rate from raw materials to finished systems

Technological Leadership

Chinese manufacturers are pioneering:
Sodium-ion batteries (mass production since Q3 2024)
300Ah+ megacells for utility-scale applications
AI-driven battery management with real-time degradation monitoring
