2024年上汽集团宣布其与固态电池生产商清陶能源共同研发的第一代固态电池已在排产宣布，旗下的智己，飞凡等等车型都会搭载固态电池，实现量产。2025年将会达到十万辆级规模的目标。 7月11号，大众汽车集团旗下的电池公司 PowerCo 和美国的固态锂电池生产商 QuantumScape (NYSE: QS) 宣布，双方已达成一项开创性协议，将 QuantumScape 的下一代固态锂金属电池技术工业化。 这期我们来聊聊固态电池的新进展。我用上市公司美国的 QuantumScape 和 2024 胡润全球独角兽中国的清陶能源举例。 数据显示，在一辆电动汽车中, 电池会占到整车成本的30%~40%。而动力电池铁三角–快充，续航能力和安全性，一直是新能源汽车消费者最关心的问题。 目前市面上用的锂离子电池，在正负极之间有一种液态电解质，这样锂离子在电池充电时就能朝一个方向流动，而在电池耗电时则朝另一个方向流动。传统的锂离子电池正在逼近容量上的物理极限，所以全球很多厂商都在专注研发固态电池。固态电池顾名思义，就是用固体材料代替液体，其中使用的固体材料包括陶瓷和硫化物等等。 固态电池并不新鲜，迈克尔 法拉第早在 19 世纪就发明了固态电解质。但是之所以不能量产，QuantumScape 的联合创始人 Jagdeep Singh 总结了四个方面的原因： 它们需要高电流密度，这样才能快速充电。如今的固态设计只能在低电流密度下工作， 充电速度不够快。 内置的锂不能过多。过多的锂会导致储存的能量减少。 需要持久耐用。有些固态设计在充放电几百次后就会失效。这些电池需要经过数十万英里的行驶才能发挥商业价值。 …
