Lithium Manganese Oxide Battery. A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.. The cathode is made of a composite material (an intercalated lithium compound)
Electrochemical charging mechanism of Lithium-rich manganese-base lithium-ion batteries cathodes has often been split into two stages: below 4.45 V and over 4.45 V , lithium-rich manganese-based cathode materials of first charge/discharge graphs and the differential plots of capacitance against voltage in Fig. 3 a and b .

Among various Mn-dominant (Mn has the highest number of atoms among all TM elements in the chemical formula) cathode materials, lithium-manganese-based oxides (LMO), particularly lithium-manganese-based layered oxides (LMLOs), had been investigated as potential cathode materials for a long period.
For instance, Lithium Manganese Oxide (LMO) represents one of the most promising electrode materials due to its high theoretical capacity (148 mAh·g –1) and operating voltage, thus achieving high energy and power density properties .
