Researchers have found that partially carbonised carbon fibres can act as both mechanical reinforcement and battery electrodes. By adjusting carbonisation temperatures between 800 and 1100 degrees Celsius, they improved both the stiffness and the electrochemical capacity of the material. These findings suggest that structural batteries can achieve up to 40 percent better performance than those using conventional intermediate modulus fibres. This development helps reduce overall vehicle weight by allowing the chassis or body to store energy.
