Energy storage systems (ESS) are technologies capable of storing energy from an external source and releasing this energy later. As the population grows and energy requirements continue to increase, a stable and continuous supply of energy becomes critical in both front-of-the-meter and behind-the-meter applications.
High battery capacity and fast charge and discharge rates make lithium-ion batteries ideal for ESS requirements.
Celgard has a broad range of products available to improve safety and enhance battery cell performance in these high energy applications.
Front-of-the-meter energy storage systems refer to utility-scale or grid-scale battery storage. These systems can be connected to distribution/transmission networks or to power generation assets like wind turbines or solar farms.
Lithium-ion batteries are the most prevalent and mature technology used in utility-scale storage systems. Batteries used in these front-of-the-meter systems withstand heavy cycling with frequent charging and discharging, which may degrade the battery over time.
Depending on the battery cell chemistry, coated or non-coated Celgard® separators are available – with features that improve safety and battery life, lower costs, and minimize the degradation of the system over time.
