Li-Ion:

It is type of rechargable battery which uses reversible reduction of lithium Ions.

It is used wide applications such as aircraft,military.

As shown in the above figure anode(-) and cathode(+) between seperator when discharging electrons will move from anode to cathode. when cahrging electrons move from cathode to anode.

Types of Li-ion:

Lithium Cobalt Oxide(LCO):

This type of cathode has stable capacities but lower capacites.Issues with thermal stability.If this battery is overcharging or

above 130 degree temperature which generates oxygen.

Lithium Manganese Oxide(LMO):

In this type anode as a graphite and cathode as a manganese oxide.

Its applications are memory backup devices.

Nickel Cobalt Aluminium Oxide(NCA):

This type is nomial voltage of 3.6 volts. It ranges from 3V to 4.2V.It can use as a fast cahrger.

Life cycle is 500. It can used in telsa Motors.

Lithium Iron Phosphate(LFP):

In this type of battery anode as graphite and cathode as a Iron phosphate. It is lower Energy density compare to other li-ion battries. Lower voltage

In this type cost to manufacture is low.better life cycles,alternative to lead-acid battery.
