From March 10 to 12, BTR New Material Group, a global leader in anode materials, showcased its innovations at The Battery Show Asia 2026 in Hong Kong. Meanwhile, BTR released two ultra-fast charging graphite anode products, including the 6C ultra-fast charging synthetic graphite T-Max and the 6C ultra-fast charging natural graphite T-Pro.
These two new products are designed to fully charge within 10 minutes. Building on this capability, they further enhance performance and service life under high and low-temperature conditions, overcoming the limitations extreme climates impose on fast-charging batteries.
At the launch event, BTR explained that its 6C ultra-fast charging anode, T-Max, utilizes customized modification of the coke raw material in synthetic graphite. Its disordered anode structure creates ultra-high-speed channels for lithium ions, resulting in less heat generation during fast charging and improved structural stability. Meanwhile, T-Pro is the industry's first natural graphite anode material to achieve 6C ultra-fast charging, while also delivering a high energy density of 365 mAh/g and excellent performance in ultra-low temperatures.
In terms of performance, the second-generation T-Max boasts a 12% improvement in high-temperature fast-charging cycle retention and an 18% enhancement in high-temperature storage performance compared to the first generation. This means fast-charging batteries equipped with this material will not lose charge when parked in summer and can be used reliably in tropical regions. T-Pro, through the synergistic optimization of its intrinsic structure and interface, effectively suppresses side reactions and controls cell expansion. Its low-temperature fast-charging performance in a -20°C environment has been improved by 10% compared to the first generation, enabling efficient fast charging and reduced energy loss in freezing conditions.
