A very light, rechargeable battery commonly used in notebook computers, cell phones and camcorders. As one of the newer batteries out today, this battery can give 40% more capacity than a comparable sized NiCd battery.
This battery is a rechargeable battery in which lithium ions move back and forth from the negative electrode to the positive electrode. Commonly found in portable electronics, these batteries are very light weight and have no memory effect (the phenomena that causes a battery to hold less of a charge than it’s capable of gradually losing capacity if repeatedly recharged after being only partially discharged).
There are 3 main components of a Lithium-Ion battery. The anode is generally made of carbon, the cathode of metal oxide and the electrolyte of lithium salt in an organic solution. These batteries can be found in a variety of shapes and sizes and have a very low self discharge rate.
