Synthesis and analysis of chitosan-lithium battery cell in various charge/discharge currents

摘要

Electricity is a form of energy that can be easily transformed into other energy forms. The purpose of this study is to analyze the chitosan-lithium battery cells. It is found that the energy of chitosan-lithium battery cells will give decreases with the decreasing of given discharge current at a very small percentage value. The greatest energy efficiency given by battery cell with charge current at 1C and discharge current at 0.2C is 12.55%. The conductivity of chitosan-lithium membrane found to be 1.25 × 10 S.cm after charge/discharge test. At charge currents 1C, high discharge (2C and 1C) current gave higher resistances compared to lower currents (0.5C and 0.3C). R value tends to decrease with decreasing discharge currents is given. However, charge current 0.7C and discharge current 0.2C did not show any significant difference between the low discharge currents and the high discharge currents.
