Abstract

A flexible and wearable lithium-oxygen (air) battery inspired by Chinese bamboo slips is constructed. In this novel battery, cathodes and anodes are woven without an air diffusion layer and any outer packaging; besides, the woven structure allows oxygen to access the cathodes from both sides freely, endowing the battery with a record energy density of over 523 W h kg<sup>-1</sup> .
