New energy industry including electric vehicles and large-scale energy storage in smart grids requires energy storage systems of good safety, high reliability, high energy density and low cost. Here a coated Li metal is used as anode for an aqueous rechargeable lithium battery (ARLB) combining LiMn2O4 as cathode and 0.5 mol l−1 Li2SO4 aqueous solution as electrolyte. Due to the “cross-over” effect of Li+ ions in the coating, this ARLB delivers an output voltage of about 4.0 V, a big breakthrough of the theoretic stable window of water, 1.229 V. Its cycling is very excellent with Coulomb efficiency of 100% except in the first cycle. Its energy density can be 446 Wh kg−1, about 80% higher than that for traditional lithium ion battery. Its power efficiency can be above 95%. Furthermore, its cost is low and safety is much reliable. It provides another chemistry for post lithium ion batteries.

原理没有说清。有点玄。

用什么设备和方法充电,能量守恒考虑没有,10秒钟内充60度电要多大容量,或者要消耗多少其它能源材料。

60度电, 10秒充电时间, 充电功率p=60x1000x3600J/10s=21.6MW, 在大学? 在电厂? 如何做实验证明? 每脑子!

 希望不是说一套,实际价值没有。因为我国学者发表在Nature, Science不少,有多少实际价值?

这样还能保护专利了吗????

希望能尽快投入生产
