BAK Battery’s new square 314Ah high-capacity energy storage cell redefines performance benchmarks with exceptional longevity, cost-effectiveness, and reliability. It delivers an ultra-long cycle life of 10,000 cycles, a high energy density of 190 Wh/kg, 2P high-power capability, and discharge efficiency surpassing 95%.

This cell performance breakthrough results from BAK’s sustained innovation in multi-material systems and structural design. The 10,000-cycle lifespan substantially lowers the full lifecycle cost per kilowatt-hour for energy storage systems, providing fundamental economic assurance for long-term operations. Furthermore, the cell has passed the industry’s most stringent nail penetration test, guaranteeing safety and reliability from the source.

In application, the 314Ah cell demonstrates wide adaptability. For home energy storage, its extended lifespan and high safety align perfectly with household demands for durability and peace of mind, supporting maximized solar self-consumption. In commercial and industrial energy storage, the cell’s high-power response and ultra-long cycle characteristics enable efficient peak shaving, load management, and significantly improved project ROI. It also serves as an ideal core component for large-scale applications, including generation-side paired storage and grid-side independent storage plants.

Today, competition in energy storage cells has evolved beyond capacity alone toward a holistic emphasis on full lifecycle cost, safety, and technological sophistication. Through continuous innovation, BAK Battery addresses core market needs for “cost reduction and efficiency improvement” together with “long-term reliability,” offering higher-value solutions for the global energy transition.
