Flexible lithium–oxygen battery based on a recoverable cathode
Although flexible power sources are crucial for the realization next-generation flexible electronics, their application in such devices is hindered by their low theoretical energy density. Rechargeable lithium–oxygen (Li–O(2)) batteries can provide extremely high specific energies, while the convent...

description | Although flexible power sources are crucial for the realization next-generation flexible electronics, their application in such devices is hindered by their low theoretical energy density. Rechargeable lithium–oxygen (Li–O(2)) batteries can provide extremely high specific energies, while the conventional Li–O(2) battery is bulky, inflexible and limited by the absence of effective components and an adjustable cell configuration. Here we show that a flexible Li–O(2) battery can be fabricated using unique TiO(2) nanowire arrays grown onto carbon textiles (NAs/CT) as a free-standing cathode and that superior electrochemical performances can be obtained even under stringent bending and twisting conditions. Furthermore, the TiO(2) NAs/CT cathode features excellent recoverability, which significantly extends the cycle life of the Li–O(2) battery and lowers its life cycle cost. |
