High Power / High Energy

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 separator solutions utilizes an array of chemistry and coating options to deliver excellent long-term cycle performance and safety.

Chemistry

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 experts will work with you to develop the ideal combination for optimal performance in your product.

Energy Density

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 technology to meet your needs.

Coatings

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.

Form Factor

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 products will be developed to conform to your design requirements and to perform at the highest standards in the final product.

Ranges

Celgard has a broad portfolio of products available in a large range of properties. All Celgard® battery separators offer
excellent energy and power performance, dimensional integrity, and chemical and thermal stability in lithium battery applications.
