Whether your battery designs require long battery life, high discharge rates, or something in between, it’s critical to have the correct combination of components to address these issues. Celgard’s family of battery separator technology solutions utilizes an array of chemistry and coating options to deliver excellent long-term cycle performance and safety.
Today’s battery requirements are constantly changing, with chemistries ranging from lower voltage LFP to higher voltage LCO, NMC and NCA. Your battery not only requires a separator with excellent electrical performance and dimensional integrity, but it also requires a material selection that is compatible with your electrochemical cell components. Celgard’s battery separator technology experts will work with you to develop the ideal combination for optimal performance in your product.
As demand for thinner batteries and higher capacities increase, higher energy density is needed to support those trends. Whether your application requires voltages between 4.25 to 4.35 or more, Celgard is committed to providing the right battery separator technology to meet your needs.
You may require a coated separator for low shrinkage, low moisture content, better adhesion, increased life cycle, or increased safety. Celgard offers several coating options from 2 to 5 μm thickness, including ceramic, which provides enhanced short prevention and excellent structural integrity at high temperatures.
Size criteria and cost considerations of cells are what drive you to decide the ultimate form factors of your battery. From lightweight prismatic pouch cells, cost-effective high density cylindrical cells, or button cells for smaller applications, Celgard’s battery separator technologies are developed to conform to your design requirements and to perform at the highest standards in the final product.
Celgard has a broad portfolio of products available in a large range of properties. All Celgard® battery separator technologies offer
excellent energy and power performance, dimensional integrity, and chemical and thermal stability in lithium battery applications.
