It is a type of rechargeable battery that is charged and discharged by lithium ions moving between the negative and positive electrodes. The batteries that can be charged and discharged repeatedly are called secondary batteries and disposable batteries are called primary batteries. The lithium ion batteries are suitable for storing high capacity power; they can be used for a wide range of applications including consumer electronics such as smartphones and PCs, industrial robots, production equipment, and automobiles.
Lithium ion batteries are extremely sensitive to high temperatures and inherently flammable. These battery packs tend to degrade much faster than they normally would, due to heat. The lithium ion battery pack fails, it will burst into flames and can cause widespread damage.
The lithium ion battery disadvantage includes the protection required. The lithium ion cells and battery are not as robust as some other rechargeable technologies. They only required protection from being overcharged and discharged too far. They need to have the current maintained to the safe limits. The minimum lifespan of lithium batteries is around 5 years and at least 2000 charging cycles. The well cared for and used in proper conditions lithium ion batteries can last as long as 3000 cycles.
The life of a lithium battery is about two to three years and 300 to 500 charge cycles wherever occurs first. The lithium ion battery continues to slowly discharge when not in use and while in storage. Routinely check the battery charges.
It is dangerous to open the battery in an uncontrolled condition by a novice. They might have built up internal pressure which gets suddenly released and may cause injury. The electrolyte is corrosive and spilled with damaged materials around and injured skin and eyes if exposed.
