Lithium batteries are suitable for use in household appliances, and are for example recommended for use with computer mice.
Lithium-ion (Li-ion) cells are suitable for applications such as laptop computers as they are relatively light. Also the voltage of 3.6V is twice that of alternative rechargeable cells e.g. Ni-Cd and NiMH batteries. They have a very long shelf-life and can withstand a wide range of temperatures.
Lithium-ion polymer is a more recent development using a lithium ion and cobalt oxide cell with a polymer electrolyte which are formed into a flat sheet. These batteries offer a considerable reduction in space required over Li-ion batteries and are used in mobile phones.
Cobalt, is used in Lithium-Ion (Li-ion) batteries - a battery contains about 32 per cent cobalt compounds by weight. The critical factor for cobalt reuse is to get the used batteries returned for recycling - with consumers requiring availability of easy take-back options for electrical goods.
