All About Lithium Ion Battery Technology

Lithium Batteries Fall under 2 Goups

In spite of the various chemical variations, lithium-ion batteries can generally be separated into two groups: lithium iron phosphate (LFP, LiFePO4) and metal oxides (NCM, NCA, Cobalt, Manganese). Table 1outlines the differences between the two chemistry classes on a cell level. The values in the table reflect average values as there is variation in each class.

All lithium-ion cells are “deep cycle” meaning that they have the ability to be fully charged and discharged. The life of the battery will significantly increase if the depth of each discharge is limited to 80% of the rated capacity.
