Introduction to cathode materials and cathode materials for cylindrical batteries

Cathode material for cylindrical batteries

At present, the mainstream commercial cathode materials for cylindrical batteries mainly include lithium cobaltate (LiCoO2), lithium manganate (LiMn2O4), terpolymer (NMC), lithium iron phosphate (LiFePO4), etc. Batteries with different material systems have different characteristics, which are compared as follows:

Cathode material for cylindrical batteries

Lithium cobaltate:

Advantages: Small battery

Disadvantages: stable charge and discharge, simple production process, expensive cobalt, low cycle life

Lithium nickel cobalt manganese ternary (LiNiCoMnO2):

Advantages: Stable electrochemical performance, good cycling performance

Cons: Cobalt is expensive

Lithium nickel cobalt manganese ternary (LiNiCoMnO2):

Advantages: Rich manganese resources, low price, good safety performance

Disadvantages: Low energy density, poor electrolyte compatibility

Lithium iron phosphate (LiFePO4):

Advantages: High reliability, environmental protection, long life

Disadvantages: low temperature performance is poor, low discharge current

Cylindrical battery anode material:

Cylindrical battery anode materials are roughly divided into six kinds: carbon anode materials, alloy anode materials, tin based anode materials, lithium transition metal nitride anode materials, nanoscale materials, nano-anode materials.

● Carbon nanoscale materials Anode materials: Currently, the anode materials that have been actually used for lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc.

● Alloy anode materials: including tin base alloy, silicon base alloy, germanium base alloy, aluminum base alloy, antimony base alloy, magnesium base alloy and other alloys, there are no commercial products at present.

● Tin base anode material: Tin base anode material can be divided into tin oxide and tin base composite oxide two kinds. Oxide refers to oxides of various valence metal tin. There are currently no commercial products.

● Lithium transition metal nitride anode material, there is no commercial product.

● Nano-scale materials: nano-carbon tube, nano-alloy materials.

● Nano anode material: nano oxide material

The above is the introduction of positive and negative electrode materials for cylindrical batteries. I believe you have a certain understanding. For more disposable lithium manganese batteries, please contact Hongli lithium battery manufacturers.
