Schematics of the Inside of a Lithium Rechargeable Battery

Caption

Electrolytes (blue elipse) surround lithium ions (green circles), forming the so-called 'solvation shell' or 'solvation sheath'. These shells move from the positive to the negative pole of the battery, when the battery is charging, and vice-versa when the battery is in use. It is believed that lithium ions associate mainly with ethylene carbonate (EC), while dimethyl carbonate (DMC) and diethyl carbonate (DEC) are just enhancing the movement of these shells between the batteries' poles, like 'lubricants'. This study showed that this theory is not completely true.
