Bite the battery to get electricity?
The general zinc-manganese battery is a chemical reaction, no electrons are emitted after the reaction, and when you bite the battery, the reaction area will be enlarged, then the remaining electrons inside the battery will be released, and naturally there will be electricity.
But not all batteries are like this. It depends on the properties of the battery.
However, Janon does not recommend the use of this method, because most of the rechargeable AA batteries are nickel-cadmium batteries and nickel-metal hydride batteries, and the cadmium component is harmful to the human body.
