丰田：2025年前量产固态电池 用30年以上保持9成性能

相较锂电池，新型固态电池存在诸多优势，因此被视作下一代动力电池的发展方向。目前，多家车企都在对固态电池进行技术攻关。丰田作为全球第一大车企，正在紧密布局。

　　早在去年 10 月东京车展开幕前夕，丰田执行总裁兼首席技术官寺岛茂树 Shigeki Terashi 就曾透露，丰田将在 2020 年东京奥运会时推出一款搭载固态电池的新能源车型，而这一车型的量产预计要到 2025 年才能实现。

　　不过，今年由于疫情冲击，东京奥运会延期到了明年，丰田的这一计划有所推迟。

　　据外媒报道， 丰田汽车动力总成公司执行副总裁兼电池业总经理 Keiji Kaita 表示，现在讨论固态电池的上市时间还太早，和很多前瞻性技术一样，起商业化同样面临多重障碍。

　　据了解，相比锂离子电池，固态电池的能量密度是其2-3 倍，且重量轻、寿命长，更加安全，也不容易受到温度对电池性能的影响。丰田的固态电池原型产品比锂离子电池充电速度也要快很多，从零到充满仅用 15 分钟。

　　Keiji Kaita 表示，丰田希望能在 2025 年前量产固态电池，初期由于成本和规模，起价格会高于锂离子电池。

　　丰田希望，其生产的固态电池可以使用 30 年以上，仍保持 90% 以上的性能。http://m.imdb.com/list/ls087039411
