时光倒流至上世纪九十年代，那是日本电池工业的辉煌岁月。 1991年，索尼发布了人类历史上第一款商用锂电池，拉开了现代电池产业的序幕，开启了消费电子的新纪元。随后的十年间，日本企业几乎垄断了全球锂电 池市场，松下、索尼、三洋组成的"三巨头"掌控着锂电市场近90%的份额。 进入21世纪，韩国企业开始崭露头角。LG化学（后更名为LG新能源）、三星SDI、SK On等韩国巨头凭借技术积累和国际化布局，迅速打开欧美市场。2011 年左右，韩国首次超过日本成为全球锂电池最大生产国。 那时的日韩企业，如同电池江湖中的武林盟主，睥睨天下。中国电池产业还处于萌芽阶段，核心材料和设备完全依赖进口，技术水平落后日韩至少十年。然 而当电动车出现后，中国电池厂商异军突起，一举超越日韩企业，这当中究竟发生了什么？ 01 也许有人还记得特斯拉问世时，拆解Model S的电池包，里面一颗颗密密麻麻排列的18650圆柱电池。 2003年，特斯拉横空出世，当时市面上的电动车主要采用的是铅酸/镍氢电池方案，能量密度低、容量小，且寿命短，根本无法满足特斯拉的要求和标准。 而特斯拉作为一个初创企业，自己又无力建设电池产线。 立志要用高性能电动车改写市 ...
