6 FAQs about [Technical agreement for battery separators]
What is senior material Europe's Lithium-ion battery separator agreement?
Under the agreement, from 2025 to 2032, Senior Material Europe will supply approximately 2.09 billion square meters of wet-process coated lithium-ion battery separators. This large-scale commitment demonstrates the company’s capability to support high-volume production and sustainable innovation in battery technology.
What is a battery separator?
A battery separator is a permeable membrane that keeps the anode and cathode, the battery’s electrodes, apart to avoid an electrical short circuit. It is a critical component. The anode is the positive electrode, and the cathode is the negative electrode.
Why do EV batteries need separators?
The continuous market demand for more autonomy and fl exibility of the EV batteries encourage manufacturers to keep developing new designs and innovative materials. Separators are thin permeable polymeric membranes that sit between the anode and cathode of a lithium-ion battery to prevent them from coming into contact – a potential fi re hazard.
How do battery separators improve battery performance?
In recent years separators have benefi tted from a number of innovations that improve their structures and properties, directly impacting battery performance in areas such as energy and power densities, cycle life, and safety.
How does a Lithium Ion Separator work?
Positively charged lithium-ions pass from the cathode, through the separator and into the anode where it is stored. When no more ions flow to the anode the battery is fully charged. Negatively charged lithium-ions travel back through the separator and into the cathode. When no more ions flow to the cathode the battery is fully discharged.
Will Entek & britishvolt co-locate a battery separator site in Northumberland?
ENTEK and Britishvolt have signed a non-binding MoU to develop battery separator technologies, with future plans to co-locate at a site in Northumberland.
