In 2026, as the robotics industry accelerates its expansion, bottlenecks in battery life and power urgently need breakthroughs! BAK Battery introduces the N21700CX-65E high-capacity cylindrical cell. Empowered by a high-nickel core material, it achieves an ultra-large single-cell capacity of 6500mAh, with exceptionally high energy densities of 928Wh/L and 315Wh/kg. From now on, robots no longer need to sacrifice compact design to possess long-lasting, robust power—say goodbye to range anxiety!
Furthermore, with an internal resistance below 8mΩ and support for up to 4C maximum discharge rate, the cell is well-suited for high-intensity operations. It also features a broad operating temperature range from -30°C to 60°C, adapting to all climate conditions. This ensures stable and powerful energy output for robots in high-demand scenarios such as rapid movement and heavy-load operations, achieving a dual breakthrough in both energy density and safety.
From core technological advancement to empowering full-scenario applications, this "Energy Capsule" will enhance performance across various robots—including humanoid, cleaning, and security robots—solving endurance challenges and helping intelligent devices enter more scenarios, ultimately enabling "long-lasting companionship."
