Pembuatan Lembaran Katoda LiFe0.9Ni0.1PO4/C dengan Variasi Suhu Pengeringan

Abstract

A research on the preparation of LiFe0,9Ni0,1PO4/C cathode sheets wich will be used as cathode of lihium battery has been conducted. The materials are active material powders of LiFe0,9Ni0,1PO4/C as filler, the polymer material PVdF as matriks, and conduvtive additives are acetylene black. The technique of making a sheet is using doctor blade methode. Research has been done to get optimum drying temperature in the fabrication of cathode sheets by doing a variety of drying temperature is 60oC, 80oC, and 100oC. Identification phase from the active material powder of cathode was done by XRD. Morphological structure sheet with SEM. The research showed that the LiFe0,9Ni0,1PO4/C cathode sheets has a highest conductivity was 1,8 x 10-5 S/cm. Battery performance was analyzed by charge/ discharge capacity test. The drying temperature of 80oC showed discharge specific capacity of LiFe0,9Ni0,1PO4/C is 28,3 mAh/g in accprdance with the result of CV.
