How does a lithium battery work?

Lithium batteries are divided into lithium metal batteries and lithium ion batteries.

1, lithium metal battery

Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its alloy metal as the negative electrode material, and use non-aqueous electrolyte. The principle of discharge reaction is: Li+MnO2 = LiMn02.

2. Lithium-ion battery

Lithium-ion batteries generally use lithium alloy metal oxides as cathode materials, graphite as cathode materials, and non-aqueous electrolyte. The reaction on the anode is: licoo 2 = = Li (1-x) coo 2+xli+xe-(electron); The reaction on the negative electrode is 6c+xli++xe-= lixc6; Total reaction of rechargeable battery: licoo 2+6c = Li (1-x) coo 2+lixc 6.

Extended data:

Compared with the traditional energy supply mode based on fossil fuels, the appearance of lithium batteries has broken the previous carbon-based energy supply mode, reduced carbon emissions and provided a new path for sustainable development.

Since 1990s, lithium batteries have entered the market, and gradually become the power supply choice for electrical appliances and IT terminal equipment. Smaller size, more stable performance and better recyclability make lithium batteries gradually spread all over people's daily lives, helping mankind to take an important step towards a clean world.
