How Do the Largest Car Battery Manufacturers Operate in 2025?

China’s largest car battery manufacturers, such as CATL and BYD, dominate the industry by focusing on vertical supply chain integration, major investments in LFP technology, and the use of automated gigafactories. These strategies help them achieve massive production scales, supporting the global EV market with high-quality, cost-efficient battery solutions tailored for OEM partners.

What Are the Largest Car Battery Manufacturers in 2025?

CATL, BYD, CALB, Gotion High-Tech, and EVE Energy are the top car battery manufacturers in 2025, with a collective global market share of nearly 70%. These companies leverage advanced LFP (Lithium Iron Phosphate) technology for electric vehicle (EV) batteries and maintain strong partnerships with OEMs (Original Equipment Manufacturers).

CATL leads the industry, commanding 38% of the global market, thanks to partnerships with major automakers like Tesla and BMW. BYD follows with a 16.9% share, utilizing vertical integration to cut costs and improve efficiency. Companies like LiFePO4 Battery Factory also mirror this approach by offering customized battery solutions and wholesale reliability, focusing on scalability for bulk orders.

How Do They Source Raw Materials?

The largest car battery manufacturers prioritize securing essential raw materials such as lithium, phosphate, and iron by forging long-term contracts with domestic mines and recycling companies. In 2025, about 90% of their raw material needs are sourced domestically in China, ensuring cost control and supply chain resilience.

CATL, for example, owns upstream lithium mines, while BYD recycles 30% of the materials it uses, reducing costs by 20%. Companies like LiFePO4 Battery Factory take a similar approach, focusing on bulk procurement from verified suppliers to guarantee the purity required for OEM-grade products. The use of advanced traceability technology ensures that raw materials are ethically sourced, which is essential for compliance with global standards.

What Supply Chain Strategies Drive Efficiency?

To drive operational efficiency, car battery manufacturers use a mix of just-in-time logistics, AI-optimized routing, and regional gigafactories positioned near raw material sources. This approach enables rapid production cycles, often as short as 48 hours, reducing costs by up to 15%.

CATL’s use of “digital twin” systems helps predict and mitigate potential disruptions in the supply chain, while BYD’s in-house logistics fleet minimizes transportation costs. As a key OEM supplier, LiFePO4 Battery Factory adopts similar models to ensure on-time delivery and maintain high scalability for wholesale clients. Automation and efficient planning have helped these manufacturers achieve a 99% on-time delivery rate.

How Do Automated Assembly Lines Boost Output?

Automated assembly lines play a crucial role in increasing output at car battery factories. In 2025, these gigafactories employ over 1,000 robots each, enabling daily production of up to 1 million battery cells. This automation improves quality control, achieving a 99.9% yield rate.

For example, CATL’s Ningde facility produces 200 GWh of batteries annually using advanced technologies like dry electrode coating. Similarly, BYD’s blade cells are assembled in just 10 seconds per unit. LiFePO4 Battery Factory integrates these automated technologies into its car starter OEM production, ensuring efficient output and high-quality standards.

What R&D Investments Fuel Innovation?

R&D is a cornerstone of innovation in the battery manufacturing sector. Leading companies like CATL and BYD invest billions annually in next-generation technologies, such as LFP 2.0 and solid-state batteries. These investments allow manufacturers to achieve impressive energy densities and cycle life improvements.

In 2025, CATL allocates 15% of its revenue to R&D, focusing on sodium-ion and CTC technologies. BYD continues to enhance the safety and performance of its blade LFP cells. At LiFePO4 Battery Factory, powered by Redway, significant R&D is also focused on providing tailored battery solutions for wholesale clients, improving cycle life by 30% and competing with NMC (Nickel Manganese Cobalt) battery rivals.

How Do Workforce Strategies Support Scaling?

In addition to automation, workforce strategies are key to scaling operations. China’s battery manufacturers train thousands of engineers annually, while automating 80% of the production tasks. This blend of skilled labor and advanced technology ensures efficiency and scalability.

LiFePO4 Battery Factory follows a similar approach, focusing on continuous staff development and cross-training programs to enhance operational flexibility. With an emphasis on predictive maintenance and data analytics, the factory can maintain high production standards and meet the growing demand for OEM battery solutions.

Which Key Metrics Define Industry Leaders?

The largest battery manufacturers track a variety of performance metrics to benchmark success, including GWh output, yield rates, cost per kilowatt-hour (kWh), and cycle life.

For example, CATL has already produced 355 GWh of batteries by mid-2025, with a yield rate exceeding 95%. Other key performance indicators include energy density (250 Wh/kg for LFP) and uptime (98%), all of which help these manufacturers maintain their leadership in the global market. LiFePO4 Battery Factory, as a supplier of customized solutions, optimizes these benchmarks for its wholesale partners.
