For this blog, we focus entirely on lithium-ion (Li-ion) based batteries, the most widely deployed type of batteries used in stationary energy storage applications today. The International Energy Agency (IEA) reported that lithium-ion batteries accounted for more than 90% of the global investment in battery energy storage in 2020 and 2021.
Visually, battery terminals are pieces of metal. These pieces may be integrated within the battery structure or connected externally. Note that batteries, as well as battery terminals, come in a variety of shapes and sizes. Hence, there is no exact visual representation of a battery terminal.

DOE ExplainsBatteries. Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical

Batteries. A battery is an electrochemical cell or series of cells that produces an electric current. In principle, any galvanic cell could be used as a battery. An ideal battery would never run down, produce an unchanging voltage, and be capable of withstanding environmental extremes of heat and humidity.
To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery''s internal resistance. Quote: "The internal resistance of a battery is like the resistance of a water pipe. The larger
