Charge and Discharge
During discharge, lithium ions Li+ carry the current from the negative to the positive electrode, through the non-aqueous electrolyte and separator diaphragm.
During charging, an external electrical power source (the charging circuit) applies an over-voltage (a higher voltage but of the same polarity) than that produced by the battery, forcing the current to pass in the reverse direction. The lithium ions then migrate from the positive to the negative electrode, where they become embedded in the porous electrode material in a process known as intercalation.

Famous quotes containing the words charge and/or discharge:
“Today I love myself as I love my god: who could charge me with a sin today? I know only sins against my god; but who knows my god?”
—Friedrich Nietzsche (1844–1900)
“Foul whisp’rings are abroad. Unnatural deeds
