To present our breakthrough in developing a biochar‑based composite phase change material that simultaneously achieves high thermal storage and high thermal conductivity for power battery thermal management. Emphasise the cost‑effective, sustainable route using agricultural waste, and demonstrate experimental evidence that overcomes the traditional trade‑off between loading capacity and heat transfer. End with a clear vision of how this material can be integrated into battery cooling systems, aiming to attract collaboration or industrial interest from the audience.
