Understanding Batteries and Battery Charging
When a battery is connected to an external load, such as lights, pumps, inverters, etc. the chemical energy stored within the battery changes into electrical energy resulting in an electrical DC current flowing out of the battery and into the connected external circuit. Thus when discharging, a battery converts chemical energy into electrical energy.
How Lithium-ion Batteries Work | Department of Energy
The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
