Batteries are used in all energy storage systems, however not all batteries are the same. There are numerous types of batteries used in battery storage systems, and new battery types are constantly being brought to the market.

Fremont, CA: One of the fastest-growing technologies in the sustainable energy business is battery energy storage systems. Energy storage systems have gained widespread acceptance as cost-effective means to reduce dependency on fossil fuels and, in some cases, unreliable electricity sources. A battery energy storage system is an excellent way to take advantage of renewable energy sources such as solar. Energy storage systems are becoming more popular in a range of industries, and they use a variety of batteries.

The main types of batteries used in battery energy storage systems are:

Lithium ion battery

Lithium-ion batteries are the most popular form of battery used in energy storage systems. Lithium-ion batteries, in fact, account for 90 percent of the global grid battery storage industry. The type of battery people are most likely to be familiar with is a Lithium ion battery. Cell phones and laptops both use lithium-ion batteries. A lithium ion battery is small and light, but it is also more costly than some of the other possibilities.

Lead acid batteries

Lead acid batteries have been used in energy storage devices for decades and are the most frequently utilized rechargeable battery technology on the planet. Since lead acid batteries are the most common type of automotive battery, one may be familiar with them. They have a shorter life expectancy than other battery types, but they are the cheapest. The most extensively recycled batteries are lead acid batteries, which have a well-established recycling mechanism.

Redox flow batteries

Chemical and oxidation reactions in redox flow batteries aid in the storage of energy in liquid electrolyte solutions that flow through a battery of electrochemical cells during charge and discharge. Redox flow batteries reduce environmental risk while improving demand response time.

Sodium-sulfur batteries

Molten sulfur and molten sodium create sodium-sulfur batteries, with the sulfur serving as the positive and the sodium serving as the negative. Since sodium is plentiful in the earth's crust, sodium-based batteries are more environmentally friendly than lithium-ion batteries.

Zinc-bromine flow battery

A hybrid redox flow battery, the zinc-bromine battery is made up of zinc and bromine. The majority of the energy in these batteries is stored by plating zinc metal as a solid onto anode plates in the electrochemical stack during charge, according to the Energy Storage Association.
