Binders and separators: With its Solef® PVDF grades, Solvay Solexis meets industry requirements for lithium battery binders and separators. Thanks to its properties, Solef® guarantees safe operation of the battery, stability and a long cycle life. It is suitable for the preparation of ink for electrodes coating, allows an easy diffusion of Li-ions and avoids capacity fade due to its good adhesion to metallic collectors.
Solef® with its brand new PVDF binder grade, Solef® 5130, provides increased adhesion, allowing for a reduction of the binder content on the battery electrodes, thus increasing the energy capacity while providing longer cycle life.
