Lithium Battery Electrode Materials

Posted by Chia-yu Chen on

Lithium-ion battery performance depends on the composition and morphology of electrode which is influenced by properties of electrode materials and the electrode preparation process. Electrode materials include active materials (AM), conductive additives (CA) and binders. Factors such as shape and size of AM/CA, AM/CA/binder ratio and slurry preparation process can affect energy, power and cycle life performance of a cell.

MSE Supplies offers various active materials, conductive additives and binders.

Active materials- Anode

Lithium metal

MSE Supplies offers lithium foils with different dimensions for anode active materials as well as lithium chips for coin cells.

 

Lithium Titanate

Lithium Titanate has been considered as one of the most promising anode powders for next-generation large scale power lithium-ion batteries. Instead of traditional carbon coating method, a unique micro spherical structure is introduced in this product which exhibits a high power density, good temperature performance and rate capability.

Graphite

Graphite is a conventional anode material. MSE Supplies offers natural graphite and high performance artificial graphite powder.

  

Active materials- Cathode

MSE Supplies also offers various cathode powders.

    

LCO

NMC

LFP

LNMO

Lithium cobalt oxide

NMC424, NMC532, NMC622, NMC111, NMC811

Lithium ion phosphate

Lithium nickel manganese oxide

 

Conductive Additives

Conductive additives are used to improve electrical conductivity of active materials. The common conductive additives are shown in the following table.

    

Carbon Black

Graphene

CNTs

CNFs

SUPER P, SUPER C45, SUPER C65, Ketjenblack, Acetylene Black

 

Carbon nanotubes

Carbon nanofibers

 

Binders

Binders have multiple tasks. They need to hold the coating particles together. They also act as surfactants to increase wetting of AM/CA and help particle dispersion.

MSE Supplies offers both solvent-based and water-based binders.

       

PVDF

PTFE

CMC

SBR

Poly(vinylidene fluoride)

Polytetrafluoroethylene

 

Carboxymethyl Cellulose

Styrene-Butadiene Rubber

Solvent based

Water based

Water based

Water based
