Electrode Sheets for Lithium-ion Battery Manufacturing
Electrode sheets contribute significantly to determining the overall performance of cells in lithium-ion battery manufacturing. Optimized for use in the latest EV and energy storage applications, our battery electrode sheet solutions can help reduce equipment costs and manufacturing time while consistently delivering exceptional battery performance.
About Our Anode and Cathode Sheets
Our anode and cathode electrode sheets are manufactured through a cost-efficient solid state synthesis approach. Offered in a standard 5″ x 10″ format and coated on one side, our copper & aluminum-foil based electrodes can be adapted to different materials compositions and particle morphologies. Our custom electrode sheet solutions are optimized according to the active material loading, coating thickness, binder solution, and current collector materials used in your battery project.
Cathode Electrode Sheet Solutions
Cell voltage, capacity, energy and power capabilities, cycle life, and temperature of operation are primary considerations when determining the best cathode option for a specific battery chemistry. Targray’s portfolio of cathode electrode sheets includes options for a wide range of applications:
|Lithium manganese oxide (LiMn2O4) is a cathode with a structure that allows the material to be discharged at high rates. LMO electrode sheet materials are a good fit for high rate applications.|
|Lithium nickel cobalt aluminum oxide (LiNi0.8Co0.15Al0.05O2) is a cathode that provides exceptional capacity. NCA electrode sheet materials are an excellent option for moderate rate applications that call for higher energy density.|
|Lithium manganese nickel oxide / spinel (LiMn1.5Ni0.5O4) is a cathode that can be charged at a higher voltage than comparable materials – up to 5V. The high energy density that LMNO electrode sheets provide makes them ideally suited for batteries used in high rate applications.|
Lithium Titanate (LTO) Anode Electrode Sheets
LTO, or Lithium titanate (Li4Ti5O12) is a highly stable anode material that is ideally suited for electrode sheets in batteries requiring high c-rates and long life cycles. Lithium Titanate-based batteries are typically safer than their counterparts, with a broader operating temperature range. LTO-based sheets feature a number of characteristics that make them highly suitable:
- High coulombic efficiency and specific capacity (mAh/g).
- Fast li-ion diffusion into anode and low first cycle irreversible loss.
- Structural consistency during charge and discharge.
- Solid electrolyte interface stability during cycling.
- Excellent ionic and electronic conductivity.
