Lithium ion batteries are one of the best energy storage systems due to their inherent safety, higher capacity and lower weight. These batteries find applications in various sectors like telecommunication, transportation and different portable electrical devices. Other advantages of lithium ion battery include their

(a) light weight
(b) high open circuit voltage
(c) low discharge rate

The low cost and environment friendly carbon coated lithium iron phosphate (LiFePO₄) and lithium titanate (Li₄Ti₅O₁₂) are the futuristic electrodes for Li ion battery.

1. These materials are presently imported by battery makers.
2. Indian entrepreneurs can directly use these materials for battery production.
3. Synthesized from readily available raw material sourced from local market.

1. These materials are electrodes materials to be used in Lithium- ion battery.
2. These batteries have applications in large scale industries like transport system, telecommunication etc.
3. These batteries are useful in small scale industries like power tools, portable electrical devices etc.

Lithium-ion batteries are one of the best energy storage systems due to their inherent safety, higher capacity and lower weight. In a lithium-ion battery, lithium ions migrate from the negative electrode to the positive electrode during discharge, and back on re-charging. These batteries have several advantages as:

1. Lithium has very high electrochemical potential
2. Lithium is a lighter element than other elements
3. These batteries has high open circuit voltage & very low discharge rate ( 5-10% )

At present lithium cobalt oxide (LiCoO₂) is used as cathode. This cathode is costly and also it has environment impact. The carbon coated lithium iron phosphate (LiFePO₄) is better choice as cathode because of its low cost, thermal stability and environment friendliness.

At present carbon is used as anode material. However, large amount of materials is required as well as carbon become stresses upon electrochemical cycling. The lithium titanate (Li₄Ti₅O₁₂) is stress free anode to be used in modern lithium ion batteries.

These two cost effective materials are useful for making electrodes in lithium ion battery.

1. Carbon coated lithium iron phosphate (LiFePO₄) is black in color.
2. The particle size of powder is in nanometer range.
3. The electronic conductivity of this material is in the range of 10^-3-10^-4 Ohm^-1cm^-1
4. Lithium titanate (Li₄Ti₅O₁₂) is white in color and very stable in dry atmosphere.
5. Particle size of these lithium titanate is in nanometer range.

1. These materials are presently imported by battery makers.
2. Indian entrepreneurs can directly use these materials for battery production.
3. Synthesized from readily available raw material sourced from local market.

1. These materials are electrodes materials to be used in Lithium- ion battery.
2. These batteries can be very much useful in large scale industries like telecommunication, transport etc.
3. These batteries would also be useful in other devices produced by small scale industries like power tools, portable electrical devices etc.

1. The raw materials are easily available in local market.

1. A chemical laboratory having a fume hood (500 m³/h) & furnace with special atmosphere facility is sufficient for production of these materials. Hot plates, magnetic stirrers, common glass wares, nitrogen gas, Ar+H₂ gas mixture are required.

1. Two chemists (B.Sc. in Chemistry) are required for the production.
