Optimization of Lithium-ion Cell Positive Electrode for Maximization of Energy Capacity

Abstract

Design expert software is employed for optimization of significant electrochemical materials to enhance low energy capacity of
lithium-ion cell that operates variety of consumer electronics devices, electric vehicles and energy storage systems. The design
expert experiment, particularly the response methodology effectively explored the variable percentage weight ratio of cathode
electrode material composition for adaptability between the predicted and actual experiments. The three optimized samples
parameters in the ratio of active material, conductive additive and binder demonstrated significant outputs. Cell sample C with a
composition ratio, 92:5:3 displays maximum capacity with high efficiency of design expert response methodology. The outstanding
responses from various runs implies substantial effect on the response by each of the factors. The ANOVA analysis and model
fitting result indicates non-significant lack of fit. The increment in the percentage weight of binder and active material improves
the battery capacity. All the optimized parameters of the three samples have results closely in agreement with the experimental
maximum capacity. The compatibility of the responses and analysis implies that the Design expert software is promising for
optimization expedient for enhancement of energy capacity of lithium-ion cells.
