Week 1 Understanding Different Battery Chemistry
LCO :- Stands for Lithium Cobalt Oxide ,it has a chemical symbol which is LiCoO2 and is abbreviated as LCO
LCO (Lithium cob.alt oxide) was invented in the year 1991 , it anode material is LiaC6 & Cathod material is LibCoO2 the ion is Li+.
The positive electrode ( cathode contains Cobalt oxide & Anode Contains graphite carbon ) & Al & Cu i.e. Aluminium & Cupper as a current collector on Cathode & Anode respectively.
Separator protects the short circuit & allow ions to move from Cathode to anode & anode to catode in Charge & discharge cycle respectively.
LMO :- Lithium Ion Manganeses Oxide :- Is a Cathode material (LiMn2O4) & a spinel structure family. invented in 1996 & Neagtive electrode is graphite Carbon as similar in LCO.
The three dimensions structure of spinel will imrove the ion flow on electorods. other advatages of spinel structure is thermal stability and safety. But life cycle is limited.
NCA :-Lithium Nickel Cobalt Aluminium Oxide ( LiNiCoAlO2)
LiNiCoAlO2 cathode & Graphite is Anode material. These type of chemistry has high power density & high cost & low safety are negative points.
It has higher energy density than other technology
NMC :- Lithium Nickel Manganese Cobalt Oxide ( LiNiMnCoO2)
The Cathode is made up of Three Material Nickel Manganese & Cobalt . & Anode is similar to other Li Chemistry Graphite Carbon.
The Charge & Discharge recation in similar as other Li Chemisty.Li-manganese batteries blend with lithium nickel manganese cobalt oxide (NMC) to improve the specific energy and incresae the life cycles.
LFP :- Lithium Iron Phosphate ( LiFePO4)
Lithium Iron Phospahate in Natural Mineral of Olivine family. LiFePO4 is a cathode material & Graphite carbon is an anode electorde. The main drop back of LiFePO4 energy density is low. But it offers an higher life cycles as compare to other Li Ion Chemistry. The Charge & Discharge chemical reactions ion & electron flow is similar to other Lithium Ion Chemistry.
LTO :- Lithium Titanate ( Li2 TiO3)
Lithium Titanate has replaced the negative electode material of graphite to Lithium Titanate to from spinel Structure. The cathode material can be NMC. The life cycel is higher than the other Li Technology. Li Titanate is very safe & low temp.discharge characteristics ( -30 degree C).
(Li4Ti5O12) This has high thermal stability on higher temp as well .
But the specific energy & cost is also big challenges in this thchnology.
