Lithium Nickel Cobalt Oxide (LiNiCoO2), commonly referred to as NCO or LCO (though LCO is also used for Lithium Cobalt Oxide), is a lithium-ion battery cathode material valued for its high energy density and moderate cycle life. Unlike lithium nickel manganese cobalt oxide (NMC), which includes manganese, NCO contains only nickel and cobalt alongside lithium and oxygen. The lack of manganese means that NCO is typically used where high energy density is prioritized over thermal stability, making it popular in consumer electronics but less common in high-power applications like electric vehicles.
Formula: LiNiCoO2.
Common Ratios: Often formulated with a high percentage of nickel relative to cobalt, as higher nickel content enhances energy density.
Appearance: Fine black or gray powder, depending on purity and processing.
Crystal Structure: Layered structure similar to NMC and LCO materials, allowing efficient lithium-ion intercalation.
Density: Approximately 4.8 g/cm³, although it can vary based on specific compositions.
Energy Density: High energy density, making it ideal for applications needing compact, high-capacity power sources.
Voltage Range: Operates within a typical voltage window of 3.0 to 4.2 volts per cell.
Cycle Life: Moderate cycle life, generally not as long-lasting as other cathode materials like lithium iron phosphate (LFP).
Thermal Stability: Limited thermal stability compared to materials with manganese or iron content, which adds some safety concerns at elevated temperatures.
Consumer Electronics: Commonly used in batteries for smartphones, laptops, and tablets due to its compact size and high energy capacity.
Medical Devices: LiNiCoO2 used in small medical devices where compact size and high energy density are needed.
Specialized Equipment: Can be found in some aerospace and defense applications that prioritize energy density over safety, although these often require additional protective measures.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
