General description

Lithium nickel cobalt aluminium oxide (NCA) is a class of electrode material that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

NCA is Aluminum doped Lithium nickel cobalt oxide (LNCO). Al doping is found very effective to suppress the cell impedance rise by stabilizing the charge-transfer impedance on the cathode side besides increasing the thermal stability of the material. NCA shows excellent electrochemical performance.

The NCA casted electrode sheets can be cut into appropriate size and is ready to be used in lithium ion batteries.

Other Notes

Crystal Structure: Rhombohedral

Operating Condiditons:
  • Recommended maximum charge voltage: 4.3 V vs Li/Li+
  • Recommended maximum charge current: 4C
  • Recommended cut-off voltage for discharge: 3.0 V vs Li/Li+
  • Recommended charge method: constant current - constant voltage

Professor Qiao’s laboratory lays out recent advances in conversion type lithium metal fluoride batteries. This review explores key concepts in developing electrochemically stable microstructures for wide Li-ion insertion channels.

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.

Lithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance.
