Lithium-ion battery is a superterm for a huge nummber of battery versions. Electrodes and electrolytes require a lot of different materials in a variety of combinations. Through these new cell types have emerged and are emerging which makes a summary about the different lithium-ion batteries impossible.
A few examples for different lithium-ion batteries are: lithium titanate batteries (LTO), lithium- cobaltdioxid batteries (LCO), lithium-manganese batteries(LMO, LNMO), lithium-polymer batteries, lithium-iron phosphate batteries (LFP), lithium-air batteries or tin-sulphur-lithium-ion batteries.
The positive electrode of a lithium-ion battery usallay consists of lithium alloys or lithium-metal oxides. The negative electrode consists of graphite, silicon or lithium-titanates.
Electrolytes are liquid and often organic. They can also exist in a (nearly) solid state through gelation. Since lithium is rather reactive with water aqueous electrolytes cannot be used.
Li-ion batteries are mainly used for portable divices with a high demand for energy like laptops, cameras, mobile phones etc. They are also used in the field of electromobility for pedelecs, e-cars or hybrid cars.
