How to determine the operating voltage of an electrode material for Lithium-ion batteries

The operating voltage of an electrode material is not always easily determined  from the discharge curve. It is best determined from a cyclic voltammogram (CV) or a dQ/dV plot in which all plateaus are tranformed into peaks. As shown in the CV below, NMC operates at ~3.7 V vs Li/Li+.

How to calculate the theoretical capacity of battery electrode materials

How to calculate the theoretical capacity of battery electrode materials The theoretical capacity of a battery electrode material can be estimated using the relation:¬† xFM where F is the Faraday constant, x is the number of faradays involved in the reaction, and M is the molar mass of the material. Hence, according to Eq.1, the […]

State-of-the-art cathode materials for Lithium-ion batteries

State-of-the-art cathode materials for Lithium-ion batteries i) 1st generation cathode: LCO The first cathode material developed for Li-ion batteries is LiCoO2¬†(abbreviated as LCO). It has a layered (hexagonal) structure with space group R-3M. The structure consisting of Li-O-Co-O-Li layers along the c axis is shown in Figure 1. Both Co and Li occupy alternating octahedral […]
