Week 1 Understanding Different Battery Chemistry

EV LIVE BATCH -16:

1.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..?

SOLUTION:

• Lithium -ion cell,is their most common form ,consists of a graphite anode , and alithium metal oxide cathode and an electrolyte of a lithium salt and a organic solvent
• Lithium is a good choice for an electrochemical cell due to its large standard electrode potential
• it is a high operating voltage

TYPES OF LITHIUM-ION CELLS :

1) Lithium cobalt oxide (LCO) battery:

• LCO (Lithium Cobalt oxide) was invented in the year 1991.
• its anode material is Liac6, the cathode material is Libcoo2 and the carrier is Li+
• its used in various application from elecronic devices to all laptop and phone batteries.

2) Lithium -ion manganese oxide (LM0) Battery:

• A lithium -ion manganese oxide battery (LMO) is lithium ion cell that uses manganese dioxide ,Mno2, as the cathode material
• They function through the same intercalation \de-intercalation mechanism as other commercalized secondary battery technlogies,such as LicoO2

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

• Lithium nickel cobalt aluminium oxide battery or NCA has been around since 1999 for special application
• high specific energy
• reasonably good specific power and long life span

4) Lithium nickel manganese cobalt oxide(NMC) batery:

• They are sometimes known as lithium manganese cobalt oxide batteries
• NMC batteries have a high specific energy or power

5)Lithium iron phosphate (LFP)battery :

• LFP batteries stand for Lithium iron phosphate (Lifepo4) batteries which is known as li-phosphate batteries as well
• low resistance properties
• 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 advantages of being faster to charger than other lithium-ion batteries
• but the disadvantage of having a much lower energy density
