Week 1 Understanding Different Battery Chemistry

Que.2:- six types of Lithium ion batteries

Specific energy: This defines the battery capacity in weight (Wh/kg). The capacity relates to the runtime. Products requiring long runtimes at moderate load are optimized for high specific energy.

Specific power: It's the ability to deliver high current and indicates loading capability. Batteries for power tools are made for high specific power and come with reduced specific energy

Performance: This measures how well the battery works over a wide range of temperature. Most batteries are sensitive to heat and cold and require climate control. Heat reduces the life, and cold lowers the performance temporarily.

Lifespan: This reflects cycle life and longevity and is related to factors such as temperature, depth of discharge and load. Hot climates accelerate capacity loss.

Safety: This relates to factors such as the thermal stability of the materials used in the batteries. The materials should have the ability to sustain high temperatures before becoming unstable. Instability can lead to thermal runaway in which flaming gases are vented.

Cost: Demand for electric vehicles has generally been lower than anticipated and this is mainly due to the cost of lithium-ion batteries. Hence cost is a huge factor when selecting the type of lithium-ion battery.

The basis for the comparison of our six types of lithium-ion batteries. The characteristics are rated as either high moderate or low where H, M and L stand for high, moderate and low respectively.

LCO;- LM0;- NMC:-

LFP:- NCA:- LTO:-

1. LCO: Lithium cobalt oxide is one of the most common Lithium-ions it has a chemical symbol which is LiCoO2, and is abbreviated as LCO. Cobalt is the core active that defines the character of the battery.

LCO batteries technology and applications

LCO (Lithium cobalt oxide) was invented in the year 1991. 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)

LMO: Lithium manganese oxide batteries which are commonly referred to as lithium-ion manganese batteries or manganese spinel. This battery was discovered in the 1980s the first commercial lithium-ion battery made with a cathode material made from lithium manganese.

2.LMO batteries technology and applications

Lithium magnesium oxide was invented in the year 1996. Its anode material is LiaC6, the cathode material is LibMn2O4 and the carrier is Li+. It is used in different applications like power tools and electric cars. LMO batteries have the ability to deliver a lot of energy in a short period of time, which makes them extremely useful for use in power tools like drills. Magnese oxide was first used as a cathode material. A three-dimensional spinel structure was formed by this structure,

3.NCA: Lithium nickel cobalt aluminum oxide-based battery (LiNiCoAlO₂). NCA batteries are becoming more and more important in in-grid storage and electrical power terrain applications.

NCA battery technology and applications

Lithium nickel cobalt aluminum oxide battery was invented in the year 1999. Its anode material is LiaC6, the cathode material is LibNi0.8Co0.15Al0.05O2 and the carrier is Li+. It is used in different applications like power grid applications, medical devices, and electric cars.

4.NMC: Lithium Nickel Manganese Cobalt Oxide battery. (LiNiMnCoO2) The cathode combination of nickel-manganese-cobalt is among the most successful Li-ion systems. The NMC systems can serve as a Power Cell or an Energy Cell.

NMC batteries technology and applications

Nickel Manganese Cobalt Oxide battery was invented in the year 2008. Its cathode material is LibNi1–x–yCoxMnyO2, and anode material is LiaC6, the carrier is Li+. They commonly use it in different applications like Energy Systems and electric cars. Nickel has high specific energy but poor stability, manganese can form a spinel structure so as to achieve low internal resistance yet provides low specific energy. NMC batteries are widely used for power tools, energy storage systems (EES) which need frequent cycling, and electrical power trains like automotives. The cathode combination typically used is 1-1-1 which means one-third nickel, one-third manganese, and one-third cobalt.

5.LFP: Lithium iron phosphate(LiFePO₄) batteries, which are 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.

LFP batteries technology and applications

Lithium iron phosphate was invented in the year 1996. Its anode material is LiaC6, the cathode material is LibFePO4 and the carrier is Li+. They use electric cars, electric buses, and electric trucks. The LFP is use in electric trucks or buses as volume or weight cheaper to manufacture than other Li-ion batteries types. In addition, they use LFP batteries in other applications like electric motorcycles which need a longer life cycle and increased safety. LFP provides good electrochemical performance with lower resistance. This is enabled by the nano-scale phosphate cathode material.

6.LTO: LTO batteries are lithium titanate (Li₂TiO₃) or li-titanate batteries, which is a class of batteries that is used in a growing number of applications. They are high-power batteries, so they are perfect for use in fast-charging stations.

LTO batteries technology and applications

Lithium tintate was invented in the year 2008. Its anode material is Li4+aTi5O12, the cathode material is LibFePO4 and the carrier is Li+. They use it in different applications like UPS, electrical power trains, solar-powered street lights, fast-charge stations, and forklifts. Other applications for LTO batteries include aerospace and military uses, and more importantly wind and solar energy storage and smart grids creation. Li-titanate is used instead of the graphite in the anode of a common lithium-ion battery and the material is formed into a spinel structure. The cathode material is either LMO or NMC. LTO batteries have lower energy density than other Li-ion battery types, which can be a disadvantage in efficiently powering vehicles.
