NMC Linimncoo2 Powder For Lithium Battery
Dec 03, 2018

Lithium Nickel Manganese Cobalt Oxide Batteries

One of the most successful li-ion cathode formulas developed to date is obtained by combining nickel, manganese, and cobalt. Lithium-Nickel-Manganese-Cobalt-Oxide (LiNiMnCoO2), abbreviated as NMC, has become the go-to cathode powder to develop batteries for power tools, e-bikes and other electric powertrains. It delivers strong overall performance, excellent specific energy, and the lowest self-heating rate of all mainstream cathode powders, which makes it the preferred option for automotive batteries.

NMC

While NMC powder can refer to a variety of blends, the formula typically consists of 33% nickel, 33% manganese and 33% cobalt. This blend, sometimes referred to as 1-1-1, is a popular option for mass-produced cells in applications requiring frequent cycling (automotive, energy storage) due to the reduced material cost resulting from lower cobalt content.


Since their development in the early 1990’s, lithium-ion batteries have become an essential energy storage device for a wide range of applications, including electronic devices, stationary storage and electric vehicles. Using Lithium Nickel-Manganese-Cobalt Oxides (NMC, NCM or LiwNixMnyCozO2 ) in lithium-ion batteries provides high power and energy densities and thermal stability. NMC materials can be tailored to reach a wide range of charge and thus can be used in various types of batteries. According to Yole Développement, NMC materials will dominate the global lithium-ion battery market. They should reaching about 51% of the global cathode material market by 2022, driven by the increasing demand for electrical vehicle applications, according to Yole’s “Status of the Rechargeable Li-ion Battery Industry” report, published in July 2017. The multiple license agreements and the recent patent war between BASF/University of Chicago (Argonne) and Umicore indicate market maturity. The number of mergers and acquisitions, patent litigations and license agreements should increase due to the growing number of companies operating in NMC materials, especially Chinese companies. The number of enforceable patents is increasing worldwide, and several companies already stand out thanks to their strong IP position. Therefore, it is a critical time to understand the global competitive environment of NMC lithium-ion batteries from a patent perspective. In-depth patent analyses of key technologies and players can help anticipate changes, detect business opportunities, mitigate risks and make strategic decisions to strengthen one’s market position and maximize return on one’s IP portfolio. For this report, we investigated the global patent landscape of NMC Lithium-ion Batteries including precursor, material, electrode and battery manufacturing issues, and all types of NMC materials, whether unmodified, modified, core-shell, or mixed with other active or inactive materials.


1. What is a cathode material?

CaCathode Active Materials are the main elements dictating the differences in composition while building positive electrodes for battery cells. The cathode materials are comprised of cobalt, nickel and manganese in the crystal structure forming a multi-metal oxide material to which lithium is added.thode Active Materials are the main elements dictating the differences in composition while building positive electrodes for battery cells.

2. What materials make up a lithium ion battery?

State-of-the-art cathode materials include lithium-metal oxides [such as LiCoO2, LiMn2O4, and Li(NixMnyCoz)O2], vanadium oxides, olivines (such as LiFePO4), and rechargeable lithium oxides. Layered oxides containing cobalt and nickel are the most studied materials for lithium-ion batteries.


3. What is a NMC battery?

Category : LiNiMnCo (NMC) Batteries. Lithium Nickel Manganese Cobalt Oxide also lithium-mananese-cobalt-oxide (LiNiMnCo, NMC, NCM), Li[NiMnCo]O2 based Cathode & Graphite based Anode, is the newest generation Li-Ion rechargeablebattery for high power applications, such as EV car, E-scooter and E-bike.
