关注 「电动车公社」 和我们一起重新思考汽车 大家好，我是电动车公社的社长。 而 小米这次公开的固态电池专利， 正是聚合物电解质路线！ 那么，小米为什么要选择 三种固态电解质中， 距离量产落地进度相对较慢的技术路线？又究竟是通过什么方式、优化了哪些问题的？ 今天我们就借此机会，来聊聊聚合物电解质前世今生。 01. 一门让塑料导电的学问 在具体讲小米全固态电池之前，我们先对聚合物电解质来一个初步的了解。 所谓 聚合物 ，其实就是小学二年级 专门学过的 有机高分子材料 ，是由一种或几种有机分子团，通过共价键连接聚合成的大分子非金属材料。 前段时 间，这篇关于固态电池的文章 《全固态电池上车，就差临门一脚了？》 收获了不少小伙伴的留言，足以看出大家对前沿技术的关注度。 但没想到，评论区竟然因为 "小米已经研发出固态电池并申请专利" ，引起了大家广泛的讨论。 你说这事巧不巧？ 上一篇固态电池的内容受限于篇幅，只和大家聊了聊呼声最高的 硫化物 电解质，另外两种技术路线 氧化物 和 聚合 物 电解质则是挖了个坑，打算以后有机 会再讲。 通俗点来说，咱们平时生活中看得见摸 得着的 塑料袋、轮胎橡胶、水路白色管道、尼龙线 等 ...
