China’s Lithium-Ion Battery Output Tops 1,240 GWh in First Half as Exports Climb 37%

China's lithium-ion battery industry continued to expand in the first half of 2026, with total output exceeding 1,240 gigawatt-hours and export value rising 37% year on year, according to figures released by the Ministry of Industry and Information Technology.

The ministry's September 15 industry report said national lithium-ion battery production increased 44% from a year earlier. The figures cover batteries used in consumer products, energy storage systems and electric vehicles, placing the industry at the center of China's wider manufacturing and clean-energy strategy.

The data show that power batteries accounted for the largest share of output. China produced 785 GWh of power batteries in the first half, while energy-storage batteries reached 420 GWh and consumer batteries totaled 40 GWh. These categories serve different markets, but together they reflect the expanding range of applications for lithium-ion technology.

Power batteries are essential to electric vehicles, including passenger cars, commercial vehicles and other electrified transport. Energy-storage batteries are increasingly used to store electricity for later use, helping grids manage fluctuations in renewable power generation and supporting commercial and residential energy systems. Consumer batteries serve products such as phones, computers and other portable electronics.

The ministry also reported that China's lithium-ion battery exports reached 337 billion yuan in value during the first half, up 37% year on year. Export growth underlines the importance of overseas markets for Chinese battery manufacturers, which supply global vehicle producers, energy developers and electronics companies.

China has built a substantial battery manufacturing ecosystem covering materials, cell production, battery packs and downstream applications. The sector's scale can help manufacturers benefit from integrated supply chains and large production volumes. It also gives China a central role in the global transition toward electric transport and renewable energy.

However, rapid expansion presents challenges. Battery producers must balance manufacturing capacity with actual demand, while customers increasingly focus on performance, safety, durability and total cost of ownership. If supply expands faster than demand in particular segments, manufacturers may face pressure on prices and profit margins.

The industry's raw-material supply chain is another important consideration. Lithium, graphite, nickel and other materials can be affected by changes in mining output, processing capacity, trade policy and international demand. Fluctuations in material prices can influence production costs and the economics of battery projects.

Technology remains a key competitive factor. Companies are investing in battery chemistry, energy density, charging performance, safety systems and manufacturing efficiency. Improvements in these areas can help lower costs and extend the range of electric vehicles, while energy-storage systems may benefit from longer operating life and improved safety.

Yet output growth alone does not establish whether the sector is becoming more profitable or whether every new factory will operate at full capacity. Production volume, export value, prices and corporate earnings measure different aspects of the industry. Investors and policymakers must examine them separately to assess the sector's long-term health.

The international market also brings regulatory and trade risks. Governments are reviewing supply-chain dependencies and the competitiveness of domestic battery industries, while companies are exploring production facilities outside China to serve overseas customers and manage logistics or policy uncertainty. These developments could reshape where batteries and their components are manufactured.

For China, the challenge is to convert its manufacturing scale into durable advantages in technology, quality and global customer relationships. Producers must continue improving products while avoiding a race based solely on lower prices and excess capacity.

The latest figures confirm that China's battery sector remains a major force in the global energy and transport transition. Its future performance will depend on the sustainability of demand, the pace of technological improvement and the ability of manufacturers to manage competition in both domestic and overseas markets.
