They are available in a variety of sizes, from very small button cells for hearing aids to the large batteries used in film cameras.
This battery finds application in high-drain devices due to its high capacity and energy density. They are generally used as an alternative because they have a slightly lower but generally compatible cell voltage.
It is also known as a rechargeable battery because it can be recharged after the battery’s energy is depleted. They are used as inverters for power supply as well as standalone power sources.
LFP batteries also contain phosphorus, which is used in food production. If all batteries today were LFP, they would account for nearly 1% of current agricultural phosphorus use by mass, suggesting that conflicting demands for phosphorus may arise in the future as battery demand increases.
As new materials are discovered or the properties of traditional ones improved, however, the typical performance of even older battery systems sometimes increases by large percentages.
In the 2000s, developments include batteries with embedded electronics such as USBCELL, which allows charging an AA battery through a USB connector, nanoball batteries that allow for a discharge rate about 100x greater than current batteries, and smart battery packs with state-of-charge monitors and battery protection circuits that prevent damage on over-discharge. Low self-discharge (LSD) allows secondary cells to be charged prior to shipping.
Benjamin Franklin first used the term "battery" in 1749 when he was doing experiments with electricity using a set of linked Leyden jar capacitors. [4] Franklin grouped a number of the jars into what he described as a "battery", using the military term for weapons functioning together.
If this kind of battery is over-discharged, the reagents can emerge through the cardboard and plastic that form the remainder of the container. The active chemical leakage can then damage or disable the equipment that the batteries power. For this reason, many electronic device manufacturers recommend removing the batteries from devices that will not be used for extended periods of time.

Leak-damaged alkaline battery Many battery chemicals are corrosive, poisonous or both. If leakage occurs, either spontaneously or through accident, the chemicals released may be dangerous. For example, disposable batteries often use a zinc "can" both as a reactant and as the container to hold the other reagents.
Lithium-ion: Li-ion batteries are commonly used in portable electronics and electric vehicles—but they also represent about 97 percent of the grid energy storage market.
Secondary cells are made in very large sizes; very large batteries can power a submarine or stabilize an electrical grid and help level out peak loads.
The outer case or bottom of the battery is commonly referred to as the negative terminals. Both terminals are very common in all types of batteries. The chemicals that surround these terminals and the battery together form the power cell.
