Rechargeable batteries power devices the same way that disposable batteries do — by chemical reactions at the positive and negative electrodes. Those reactions allow positively charged ions to move from one electrode to the other inside the battery, and negative electrons to move through the wires in the circuit, producing a current.
It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network.
The electric input and output of a battery determine its capacity to provide power to the device and to receive power during charging. Charging and discharging are the two main processes that occur in a battery’s input/output cycle. During the charging process, the battery receives electric input from an external power supply or charging cable.
Scientists study processes in rechargeable batteries because they do not completely reverse as the battery is charged and discharged. Over time, the lack of a complete reversal can change the chemistry and structure of battery materials, which can reduce battery performance and safety.
Unlike primary batteries, secondary batteries can be recharged by applying an external electrical current that reverses the chemical reactions within the battery. This allows the battery to restore its energy capacity and be reused.
One of the most effective solutions for providing backup power is a battery system that supports efficient input and output. When it comes to batteries, the input refers to the process of charging, while the output refers to the process of discharging.

DOE Explains...Batteries | Department of Energy
To accept and release energy, a battery is coupled to an external circuit. Electrons move through the circuit, while simultaneously ions (atoms or molecules with an electric charge) move through the electrolyte. In a rechargeable battery, electrons and ions can move either direction through the circuit and electrolyte.
