POLYVINYLIDENE FLUORIDE BASED CATHODE PRODUCED BY ELECTROSPINNING OF THE LiFePO4 BASED ELECTRODES

The cathode is one of the key components in lithium batteries since its properties significantly affect the battery performance. Therefore, currently, the research in the field of cathode synthesis and modification is quite relevant. Among the various widely used strategies aimed at improving the electrochemical performance of batteries, the application of cathode surfaces is one of the extremely useful and widely used technologies. Electrospinning technology is one of the methods to produce porous electrodes out of a polymer solution by applying electrostatic forces to the solution. Polyvinylidene fluoride is one of the common polymer-binding agents in lithium-ion batteries. It is characterized by a useful combination of elasticity and mechanical strength that allows using it in the electrospinning method. The purpose of this work was the attempt to optimize the microstructure of the cathode coating by fabrication of the fiber cathode based on lithium-iron-phosphate with the help of the electrospinning technique using polyvinylidene fluoride.
