Abstract: A method of estimating a maximum specific capacity of a composite electrode includes generating open circuit potential (OCP) crossover characteristics of the composite electrode comprising silicon and natural graphite, determining a composite electrode lithiation limit of the composite electrode based on a silicon lithiation limit of the silicon, predicting a composite electrode composition of the composite electrode based on the composite electrode lithiation limit, and estimating the maximum specific capacity of the composite electrode based on the composite electrode composition.

Abstract: A battery management system and method to control charging of a battery is provided. The system determines whether a current capacity of the battery is greater than a predetermined threshold percentage of an original rated capacity of the battery, in response to initiation of a charging cycle of the battery being detected, controls the battery to be charged with a first voltage, in response to the current capacity of the battery being determined to be greater than the predetermined threshold percentage of the original rated capacity of the battery, and controls the battery to be charged with a second voltage, in response to the current capacity of the battery being determined to be less than or equal to the predetermined threshold percentage of the original rated capacity of the battery.
