Lithium Polymer Battery with PVDF-based Electrolyte Doped with Copper Oxide Nanoparticles: Manufacturing Technology and Properties

Abstract

An overview of electrolyte materials for lithium polymer batteries and the prospects for adding metal oxide nanoparticles to the electrolyte are presented in this paper. A procedure for the synthesis of a gel polymer electrolyte based on polyvinylidene fluoride doped with copper oxide nanoparticles is also described, and the ionic conductivity is measured by the electrochemical impedance spectroscopy. Cells with the synthesized electrolyte and LiFePO4 electrode have been assembled and cycled at different currents. Stable cycling and high capacity have been exhibited by the cell with electrolyte doped with copper oxide nanoparticle (wt. 0.1%).

Review of Materials for Electrodes and Electrolytes of Lithium Batteries

“…Dorogov et al [89] studied the effect of the concentration of CuO nanoparticles (< 50 nm) in a PVDF-based electrolyte on battery performance. Specific ionic conductivity for a sample containing 0.1 wt.% CuO nanoparticles was 5.85•10 -3 S/cm, which is a high conductivity comparable to that of liquid electrolytes.…”

Titanium Dioxide for Hydrogen Economy: a Brief Review

“…The addition of semiconductor nanoparticles such as CuO, TiO2, Ga2O3 is one of the promising ways to improve the properties of materials used in hydrogen production and storage devices. Nanoscale materials have many special properties that differ from the bulk properties of the same materials [13][14][15][16][17][18]. For example, titanium dioxide is a fairly cheap and widespread material known for its excellent photocatalytic properties [19][20][21][22][23][24].…”
