Researchers develop graphene composite materials for efficient thermal management of Li-ion batteries

Researchers from China's Zhejiang University have developed a new thermal management system to prevent thermal runaway of Li-ion battery (LIB) cells, using hyperbolic graphene phase change composites. This addresses the safety concerns of LIB cells, mainly caused by thermal runaway. While phase change material systems already exist, the unresolved trade-off between high power and energy density greatly limits its practical applications.
