What is LFP & NMC cell

Two of the more commonly used lithium-ion chemistries--Nickel Manganese Cobalt (NMC) and Lithium Iron Phosphate (LFP)--are considered in detail here. Lithium-ion batteries are used in a variety of ways, from electric vehicles to residential batteries to grid-scale applications.

LFP  Cell lithium iron phosphate battery (LiFePO4) 
The   movement of the lithium ions creates free electrons in the anode and as a result, electrons will flow through an external circuit to the cathode i.e. positive terminal, and accordingly, a current will flow from the positive terminal to the negative terminal when an electric load is connected across the battery 

NMC Cell Lithium-Nickel-Manganese-Cobalt-Oxide (LiNiMnCoO2

NMC batteries offer a combination of Nickel, Manganese and Cobalt. They are sometimes known as Lithium Manganese Cobalt Oxide batteries. NMC batteries have a high specific energy or power. This limitation of either 'energy' or 'power' makes them more common for use in power tools or electric vehicles.
