目前,鋰離子電池因為其高能量密度作為電動汽車動力電池而受熱捧,但自身也有不可回避的缺點,一個是安全問題,另一個是成本問題;而液流電池有一個好處就是可以把能量和功率分開,應用于大規模儲能時成本較低,安全性較高。為解決鋰離子電池的實際問題,陳永翀提出了鋰離子液流電池的概念,即結合兩種電池的優點,讓鋰離子電池固定的兩極流動起來。

在5月24日召開的北京國際儲能大會上,陳永翀首次公開介紹鋰離子液流電池的研究進展及突破。他指出,鋰離子液流電池有以下特點:第一,它的電極懸浮液粘度大,對于電池反應器的設計有特殊要求;第二,電化學反應在流體內部發生,不是在固定的電極表面,因此電極懸浮液可以間歇或連續流動;第三,提供了發揮嵌鋰材料優勢的一個獨特方式:只要材料晶格不坍塌,顆粒體積的反復膨脹與收縮導致材料粉化并不影響材料的循環性能;第四,目前電池的能量密度介于全釩液流電池和鋰離子電池之間,未來還有很大的提升空間;第五,電池可維護,可回收;第六,與大規模鋰電池組相比,安全性大大提高。
