General description

Lithium manganese nickel oxide (LMNO) 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

LMNO is a spinel cathode material that has a storage capacity greater than 200 mAhg−1 at a voltage around 4.7 V. It has a high irreversible capacity due to its inherent property to self-discharge. LMNO can be used in the fabrication of high-performance lithium-ion batteries.
LMNO is cathode material with good electrochemical performance for high power and high energy density Lithium ion batteries. LMNO can can intercalate Li reversibly at a high voltages.

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