What is an Energy Storage System

Need help? Ask the expert

What is a battery energy storage system?

A battery energy storage system is a sub-set of energy storage systems, using an electro-chemical solution. In other words, a battery energy storage system is an easy way to capture energy and store it for use later, for instance, to supply power to an off-grid application, or to complement a peak in demand. They are usually not used to replace grid power completely but instead used to offer short-term solutions in applications where access to grid power is intermittent or the use of a generator is unsuitable due to noise or pollution concerns. Energy storage systems are also often used to manage energy generated from intermittent sources, such as solar panels. 

A variety of different battery technologies is available for use in battery energy storage systems. However, in recent years solutions using Lithium-Ion batteries have grown in popularity, driven by their long working life, wide operational strange, lightweight structure, high energy-efficiency, and, crucially, the falling cost of the technology . These, combined with the low total cost of ownership and sustainability, make them attractive for several applications. 

How does a battery energy storage system work?

A Li-ion battery comprises:

  • Cathode (+): A lithium compound with different ions coming from different raw materials such as iron, phosphate, and cobalt.
  • Anode (-): Usually, graphite that also contains lithium
  • Separator: The separator allows the ions to flow, controlling the charge so it is not discharged all at once.
how does a battery work
In a Li-ion battery, the electrolytes carry positively charged lithium ions between the anodes and the cathodes through the separator. As the lithium ions move, the movement creates free electrons in the anode, creating a charge at the positive current collector. This enables the electrical current to flow on from the current collector, through the device being powered, and back to the negative current collector.
how does a battery work
When the battery is powering a device, such as a generator, the anode releases lithium ions to the cathode, effectively creating a flow of electrons from one side to the other. In rechargeable batteries, this flow is reversed when the battery charges, as the lithium ions are released by the cathode and received by the anode .

Atlas Copco’s ZenergiZe range is a good example of how the high-density li-ion batteries can be leveraged to enable a new level of sustainability, flexibility, and usability, without compromising on power.
