''Similar to Li-manganeseLMO, these systems can be tailored to serve as Energy Cells or Power Cells. For example, NMC in an 18650 cell for moderate load condition has a capacity of about 2,800mAh 2800 mAh and can deliver 4A 4 A to 5A5 A; NMC in the same cell optimized for specific power has a capacity of only about 2,000mWh 2000 mWh but delivers a continuous discharge current of 20A20 A. A silicon-based anode will go to 4,000mAh 4000 mAh and higher but at reduced loading capability and shorter cycle life. Silicon added to graphite has the drawback that the anode grows and shrinks with charge and discharge, making the cell mechanically unstable.''

''NMC is the battery of choice for power tools, e-bikes and other electric powertrains. The cathode combination is typically one-third nickel, one-third manganese and one-third cobalt, also known as 1-1-1. This offers a unique blend that also lowers the raw material cost due to reduced cobalt content. Another successful combination is NCM NMC with 5 parts nickel, 3 parts cobalt and 2 parts manganese. Further combinations using various amounts of cathode materials are possible. New electrolytes and additives enable charging to 4.4V4 V/cell and higher to boost capacity''
