Battery Energy Storage: How it works, and why it''s important
Battery energy storage systems manage energy charging and discharging, often with intelligent and sophisticated control systems, to provide power when needed or most cost-effective.
How do batteries store and discharge electricity?
There are two fundamental types of chemical storage batteries: the rechargeable, or secondary cell, and the non-rechargeable, or primary cell.
Battery Storage and Recharge
Dispose of batteries if the maximum charge times are exceeded. Long-term storage of lithium batteries will cause capacity loss. The longer the storage duration, the greater the capacity loss. Batteries may fail the discharge acceptance tests when their capacity after storage is less than 100% of the rated capacity.

How to Discharge a Battery?
The steps to perform a controlled battery discharge test are as follows: Connect the battery to the discharge tester. Set the discharge rate and time. Start the discharge test. Monitor the battery voltage during the discharge test. Stop the discharge test when the battery voltage reaches the cutoff voltage.

Energy Storage
Say you have a battery with a round-trip efficiency of 80%. HOMER assumes the charge efficiency is equal to the discharge efficiency, meaning they are both equal to the square root of 80%, which is 0.894. So if you put 100 kWh of DC electricity into the battery (assuming it could absorb it all) then the energy level in the battery would

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.
