Batteries are a non-renewable form of energy but when rechargeable batteries store energy from renewable energy sources they can help reduce our use of fossil fuels and cut down carbon dioxide and greenhouse gas production. Find out why batteries may have a key role to play in making our energy supply greener.
“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity,” says Antoine Allanore, a postdoctoral associate at MIT’s Department of Materials Science and Engineering.
Only some of these can be recharged, which scientists call “secondary cells” – but for others, like most AA and AAA batteries, using the stored energy is a one-way street. Didi - Whether a battery is rechargeable or not depends on what the positive and negative electrodes are made of.
Batteries convert chemical energy directly to electrical energy. In many cases, the electrical energy released is the difference in the cohesive [ 17 ] or bond energies of the metals, oxides, or molecules undergoing the electrochemical reaction.
If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes). These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed.
Batteries were invented in 1800, but their complex chemical processes are still being studied. Scientists are using new tools to better understand the electrical and chemical processes in batteries to produce a new generation of highly efficient, electrical energy storage.

Electric battery
Thus converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. [3]

Batteries: Advantages and Importance in the Energy Transition
For batteries, there is a specific parameter that indicates the condition of the battery, called state of health (SOH). SOH indicates the level of performance of the storage system, based on voltage, self-discharge, and internal resistance. This parameter varies in the range 0–1, and an SOH equal to 1 indicates a battery at the beginning of its useful life, in …
