British scientists have invented a "urine battery" that can charge a smartphone for three hours with just 0.5 liters of urine. Under normal circumstances, the normal person's 24-hour urine output is about 1.5 liters, which can continuously charge the mobile phone for 6 hours. The principle of power generation of "urine battery": The power generation device contains microorganisms that decompose the chemical substances in the urine, and the energy released during the decomposition process is stored in the internal capacitor of the microbial fuel cell in the form of electric energy.
