摘要： A method for improving the environmental stability of cathode materials used in lithium-based batteries. Most currently used cathode active materials are acutely sensitive to environmental conditions, e.g. leading to moisture and CO2 pickup, that cause problems for material handling especially during electrode preparation and to gassing during charge and discharge cycles. Binder materials used for making cathodes, such as PVDF and PTFE, are mixed with and/or coated on the cathode materials to improve the environmental sensitivity of the cathode materials.
