摘要

A rationally designed air chargeable energy storage device is demonstrated, which can be effectively charged by harvesting pervasive energy from the ambient environment. For an air chargeable zinc-ion capacitor system, the system simply consists of a flexible bifunctional U shaped electrode (with the functions of energy harvesting and storage), a zinc metal electrode in middle, and two different polyelectrolytes (polyacrylamide and sodium polyacrylate) sandwiched between the zinc metal and U shaped electrode. When the zinc-ion capacitor is exhausted, it can be quickly charged to 88% within 10 min by simply opening the sealing tape and allowing the air diffuse in. The capacitor exhausting-air charging processes are repeated 60 times and the whole system works well. When the external power supplier is available, both the zinc-ion capacitor and air charging component can be fully recovered. A large capacity (approximate to 1000 mAh) air chargeable zinc-vanadium battery is also demonstrated. The zinc-vanadium battery can be fully charged by air in 1 h. This work offers a usage scenario independent reliable self-chargeable power supply system as a promising approach to solve the intermittent and unpredictable nature of currently developed self-chargeable devices.
