最近，动力电池悄悄进入了"尴尬期"，具体表现为产品的进步越来越难取悦消费者。 就拿今年年初新能源汽车行业再次掀起的"超高速充电"来说，通过应用一系列新技术，一批全容量充电倍率 4C～5C、高效区间充电速率7～8C的产品开始亮相（多家企业推出在即），意味着车辆可以在十多二十分 钟内完成完整充电。 与此前的全容量2C，高效区间4C～5C的动力电池（相当于半小时以上充满，高效区间十多二十分钟充好） 相比，充电速率提升了50%～70%，将新能源车的补能速度提升到接近燃油车的水平。 但随着时间的流逝，数字大幅提升带来的兴奋感很快就消失不见。消费者实际面对的，仍是快充设施普及 率低、商业快充成本高等问题，绝大部分用户继续每晚用自己7kW家充桩补能，甚至还要定时充上晚上12 点最便宜的"峰谷电"。 想要革新动力电池的"技术路线"，首先肯定要找到问题出现在哪里。但很多人肯定想不到，这口"锅"只能由 电化学的基础物理特性背。 就拿目前市占率最高的磷酸铁锂来说，常规的石墨负极构型下，其理论能量密度极限就是200Wh/kg左右， 目前量产的产品已经做到了205Wh/kg，在不改变构型的情况下，潜力基本已经穷尽。 又因为目前乘用车留 ...
