As global warming and climate change caused by fossil fuel grew to be a public concern, find a clean and sustainable substitute energy had become a scientific hotspot. Urea is a hydrogen carrier which makes it a feasible energy source. The urea-rich wastewater or urine which normally contains 0.33 M urea were used as fuels, which can generate electricity while processing wastewater to reduce water pollution and others. Moreover, It is considered to have a great application in aerospace to recycle the urine produced by astronauts.

Lithium-ion batteries (LIBs) have played an important role as the main source of power for various industries such as electric vehicles (EV) and solar energy storage tanks. LIBs have many advantages such as long cycle life, high power density and relatively low discharge speed. As the electric vehicles (EV) is growing massively in China and USA, however, the storage capacity has limited the driving range greatly.
