AIM:- To understand different Battery chemistry.

OBJECTIVES:-

1)Prepare a table that includes materials & chemical reactions occurring at the anode and cathode of different types of lithium-ion cells.

2)Comparing the differences between each type of Li+ion battery based on their characteristics.

Q1.Prepare a table which includes materials & chemical reactions occurring at the anode and cathode of LCO, LMO, NCA, NMC, LFP and LTO type of lithium ion cells.Give your detailed explanation on it:-

introduction :-

Lithium ion cell is most commen form of consist an garphite is anode and lithium metal oxide is cathode and the electrolyte is lithium salt and organic solvent Lithium is a good choice for an electrochemical cell due to its large standard electrode potential (–3.04 V) resulting in a high operating voltage

1)Lithium cobalt oxide(LCO) battery

LCO (Lithium cobalt oxide) was invented in the year 1991. Its anode material is LiaC6,and the cathode material is LibCoO2 and the carrier is Li+.It is used in various applications ranging from electronic devices to all laptops and phone batteries. The majority of lithium-ion batteries for portable devices are cobalt-based. The system contains a cobalt oxide cathode (positive electrode) and graphite carbon anode (negative electrode).

2)Lithium-ion manganese oxide (LMO)battery:-

lithium ion cell that uses manganese dioxide, MnO2, as the cathode material. They function through the same intercelection de-intercalation mechanism as other commercialized secondary battery technologies, such as LicoO2. Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.

3)Lithium nickel cobalt aluminium oxides (NCA) battery:-

Lithium nickel cobalt aluminum oxide battery, or NCA, has been around since 1999 for special applications. It shares similarities with NMC by offering high specific energy, reasonably good specific power and a long life span.

4)Lithium Nickel Manganese Cobalt Oxide (NMC) battery:-

In short, NMC batteries offer a combination of Nickel, Manganese and Cobalt. They are sometimes known as Lithium Manganese Cobalt Oxide batteries. NMC batteries have a high specific energy or power.

5)Lithium iron phosphate battery(LFP) batteries:-

LFP batteries stands for Lithium iron phosphate(LiFePO₄) batteries, which is known as li-phosphate batteries as well. They use phosphate as cathode material. In addition, they benefit from the low resistance properties that enhance their thermal stability and safety.

6)Lithium-titanate-oxide(LTO) battery:-

The lithium-titanate-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge than other lithium-ion batteries, but the disadvantage of having a much lower energy density.

Q2.Compare the differences between each type of Li+ion batteries based on their characteristics:-

Types	Chemical name	Cathode material	Chemical Reaction at the cathode(discharge)	Anode material	Chemical Reaction at the anode(discharge)	Overall reaction
Lithium Cobalt Oxide (LCO)	LiCoO₂	Lithium Cobalt Oxide		Graphite carbon
Lithium-ion manganese oxide battery (LMO)	LiMn₂O₄	Lithium manganese oxide		Graphite carbon
Lithium nickel cobalt aluminium oxides (NCA)	LiNiCoAlO₂	Lithium Nickel Cobalt Aluminum Oxide		Graphite carbon
Lithium Nickel Manganese Cobalt Oxide (NMC)	LiNiMnCoO₂	Lithium Nickel Manganese Cobalt Oxide		Graphite carbon
Lithium iron phosphate battery(LFP)	LiFePO₄	Lithium iron phosphate		Graphite carbon
Lithium-titanate-oxide (LTO) battery	Li₂TiO₃	Manganese oxide		Lithium titanium oxide
