Background of the invention
In 1799, the scientist Volta (Volta) used a wet rag containing salt water, sandwiched between silver and zinc circular plates, and piled them into a cylindrical shape to create the earliest one-volt battery.
The working principle of the salt water vehicle experiment magnesium air salt water battery is a type of chemical reaction device that converts the chemical energy of the magnesium alloy plate and the electrolyte (salt concentration 10% ± 10) into electrical energy. The system is mainly composed of air anode, neutral salt electrolyte and metal magnesium plate cathode. The air anode sucks in the oxygen in the air to undergo a reduction reaction, while the magnesium alloy plate and the electrolyte undergo an oxidation reaction to generate electricity. After the magnesium alloy plate is consumed as a fuel, it can be replaced with a new plate to continue generating electricity.
Cathode (-):MG+2OH- Mg(OH)2 +2e
Anode (+):O2+2H20+4e 4OH-
Overall reaction:2Mg+O2+2H2O 2Mg(OH)2
The potential difference between the two poles:E=2.23V
