固态电池和现在的锂电池有什么区别?
Zhong Guo Zhi Liang Xin Wen Wang· 2025-10-10 08:42
但是因为这个结构,特别是电解液的存在,会使电池逐渐衰减并且存在安全隐患。如车辆发生碰 撞,电池受外力挤压,电池内的电解液就会流出并造成热量堆积、气体散发,在极端条件下可能燃烧并 释放大量有毒气体。 小到手机,大到飞机,数以亿万的锂离子电池推动着社会的运行,也给人类带来无尽的益处,现代 社会的运转,已经完全离不开锂电池。在汽车领域,目前几乎市面上所有的新能源汽车都搭载锂电池 ——不管是三元锂还是磷酸铁锂。 2019年10月9日,瑞典皇家科学院宣布,将2019年诺贝尔化学奖授予约翰·B·古迪纳夫(John B. Goodenough)、M·斯坦利·威廷汉(M. Stanley Whittingham )、吉野彰(Akira Yoshino),以表彰他们 为发展锂离子电池而作的贡献。 锂电池的安全 可充电的锂离子电池诞生至今已超过50年,仅此一款产品的全球销售额每年逾450亿美元,未来10 年预计超过1000亿美元。1972年,埃克森公司的M.斯坦利·惠廷汉姆(M. Stanley Whittingham)开发了 初代版本的锂离子电池,以二硫化钛作为阴极,使用锂离子作为电解液。 惠廷汉姆电池的工作原理是将离子插入电 ...
