我国新能源汽车产业的狂飙突进，将动力电池与燃料电池推至车用动力变革的前沿。从材料实验室的微观突破到整车系统的集成革命，一场围 绕能量密度、安全边界与成本效率的技术竞逐正在重塑产业格局。在第五届车用动力系统国际论坛动力电池及燃料电池分会场中，与会专家学者针 对动力电池与燃料电池的技术革新与未来发展，进行了系统阐释和剖析。 动力电池能量密度与安全性全面提升 新能源汽车对续航里程需求提升，提高动力电池能量密度成为关键因素。当前锂离子电池虽占主流，但其能量密度接近理论极限，而富锂锰基正极材料 因高比容量和低成本优势，成为提升电池能量密度的优质材料。"富锂正极材料能够实现300mAh/g的比能量。如果用于固态电池，电池能量密度能达到 600~700Wh/kg甚至更高，为电池发展注入新的动力。"北京大学教授夏定国说。 据介绍，富锂锰基材料通过优化电池结构有望大幅提升能量密度，但面临循环稳定性和电压衰退问题。夏定国带领团队通过系统研究，解决了这些问 题，实现富锂材料在保持高倍率的同时不产生电压衰退。 中国汽车工程学会科技创新部总监曲婧瑶则从电气架构角度提出支撑方案："高功率负载（如主动悬架/旋转座椅）需48V架构支撑（欧姆 ...
