Produced more than 35 GWh of green energy

Battery energy storage is by far one of the most proven forms of energy storage technologies. Batteries have found various end-market applications ranging from consumer electronics like laptops and cell phones, storage applications in vehicles to applications such as backup power for grid and off-grid applications. Ever since the first battery technology was invented in 1800, there have been many different types of batteries that have been developed — each with its specific end market application.

Historical Timeline

1st century AD

The Baghdad Battery, sometimes referred to as the Parthian Battery, is the common name for a number of artifacts created in Mesopotamia, possibly during the Parthian or Sassanid period (the early centuries AD), and probably discovered in 1936 in the village of Khuyut Rabbou’a, near Baghdad, Iraq.



Italian physicist Alessandro Volta makes the first battery. His “voltaic pile” - as it comes to be?known - consists of stacks of zinc, acid-moistened cardboard and copper.



Gaston Plante invents the lead-acid battery used in cars up to this day.


German scientist Dr. Carl Gassner invents the “dry cell”. His battery is similar to the carbon-zinc batteries of today.


Thomas Alva Edison improves the car battery. His other battery improvements make their way into trains, and mines.


Miniature silver-oxide batteries or “button batteries” are developed for hearing aides and watches. The first nickel-cadmium rechargeable battery system is developed by Waldmar Junger in Sweden.


The first lithium batteries are commercially available. These are the most powerful AA-size batteries on the market.


Innovations in rechargeable technology introduce products such as Nickel-Metal hydride rechargeable batteries, Titanium high-performance batteries, Sodium-Sulfur (NAS) batteries or Vanadium Redox batteries. Even though these new technologies have been proven to work, they are not widely used due to their higher price and safety concerns.
