Cell Materials

Li Metal for Anode:

	Extrusion	Rolling
Thickness	0.1-3.0mm	20-90 μm
Width	15-100mm	30-55 μm

Alloy foil is available too. (Mg, In, Al…)

Perforated Foils:

• Thick Coating (Higher energy density)

  • Thicker coating to be easier due to its binding capability improvement.

• Cycle Performance (Longer life)

  • The adhesion between a foil and electrode gets very high. 

• C-Rate Performance (Lower resistance)

  • V shaped cracks retain electrolytes well, improve its permeability to the deep and expand the reaction area.

Safety
Cycle Life

• High Voltage (LFP Alternative)

  • 4.0V System with high safety and cycle performance

• Blending Effect（blended with NMC）

  1. Thermal Stability
     • High-Ni Cell to be more thermally stabilized.
  2. C-Rate Performance
     • Small particles of LMFP to fill the gaps of active materials.
  3. Cycle Performance
     
     • Reliable olivine structure of LMFP improves the cell’s cycle performance.
