Types of Li-Ion Batteries
Li-Ion battery is a type which is commanly used in most of the industries because of its rechargeable purpose and for its easy to use purpose and for less cost the Li-Ion batteries are 5 types
1)Lithium-Nickel manganese cobalt (LiNiMnCoO2)
Lithium nickel manganese cobalt oxide (NMC) batteries combine the benefits of the three main elements used in the cathode: nickel, manganese, and cobalt. Nickel on its own has high specific energy but is not stable. Manganese is exceptionally stable but has a low specific energy. Combining them yields a stable chemistry with a high specific energy
Material Properties
.Its a combination of one-third nickel, one-third manganese, one third cobalt
2)Lithium – Nickel cobalt aluminium (LiNiCoAIO2)
NCA batteries, or lithium nickel cobalt aluminum oxide batteries, are making their way in electric vehicles and grid storage.
Although NCA batteries are not widely used in consumer electronics, they have great potential in the automobile industry. NCA batteries offer a high-energy choice with a long lifespan, but they are less safe than other lithium-ion battery types and are rather expensive. To ensure driver safety, NCA batteries must be accompanied by monitoring systems
Material Properties
It consists aluminium as addition to the lithium like other models.
3) Lithium-Manganese Spinal ( LiMn2O4)
Lithium manganese oxide batteries are sometimes known as lithium manganate or lithium-ion manganese batteries, or li-manganese or manganese spinel batteries. The technology for this sort of battery was initially discovered in the 1980s, with the first publication in the Materials Research Bulletin in 1983.
Material Properties
It uses manganese as cathode
4) Lithium Titanium Oxide (Li2TiO3)
Li-titanate batteries are being employed by makers of electric vehicles and bicycles, and this type of battery has the potential to be used in electric buses for public transit. However, these batteries have a lower intrinsic voltage or energy density than other lithium-ion battery types, which might cause problems when it comes to efficiently power automobiles. Despite this, lithium titanate batteries have a higher density than non-lithium-ion batteries, which is a benefit.
Material Properties
Li-titanate used as anode and Li-manganese used as cathode
5) Lithium-Ion Phosphate (LiFePO4)
Phosphate was identified as a cathode material for rechargeable lithium batteries in 1996 by the University of Texas (and other collaborators). Li-phosphate has a low resistance and strong electrochemical performance. The nano-scale phosphate cathode material allows for this. The high current rating and long cycle life, as well as strong thermal stability, increased safety, and tolerance if mistreated, are the main advantages.
Material Properties
Lithium and Phosphate as cathode
6)Lithium Cobalt Oxide (LiCoO2)
Lithium cobalt oxide (LCO) batteries have high specific energy but low specific power. This means that they do not perform well in high-load applications, but they can deliver power over a long period
Material Properties
.It has Graphite carbon anode and a cobalt oxide cathode
