A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of technology that uses a group of in the grid to store. Battery storage is the fastest responding on , and it is used to stabilise those grids, as battery storage can transition from standby to full power in u.

A lithium-ion battery or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li ions into electronically conducting solids to store energy. One of the earliest examples of research into lithium-ion batteries is a CuF 2/Li battery developed by in 1965. The lifespan of a lithium-ion battery is typically defined as the number of full charge-discharge cycles to reach a failure threshold in terms of capacity loss or impedance rise.

A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy. Most of the BESS systems are composed of securely sealed , which are electronically monitored and replaced once their performance falls.

Today, the most common battery storage systems use 3-phase inverters based on the actively switched B6 topology or 3-level inverters. Such battery storage systems achieve efficiencies of about 97 percent due to high DC voltages with high frequencies and subsequent filtering. If one would implement a device with the same performance with a B6 bridge, for example, one would use SiC. As already mentioned, the h-bridge multi-level topology has incomparable advantages, which are multiplied by the factor of the number of modules.

Ein Natrium-Schwefel-Akkumulator, abgekürzt NaS-Akku, NaS-Batterie ist ein Akkumulator, eine sogenannte Sekundärzelle mit einer Spannung von 1,8 bis 2 Volt. Gegenüber anderen Akkumulatortypen werden statt eines flüssigen Elektrolyten ein fester Elektrolyt und flüssige Elektroden eingesetzt und für den Betrieb. Die besteht aus geschmolzenem , die aus einem mit flüssigem getränkten Graphitgewebe.
