Product Properties
The detection instrument tests the performance of graphitized battery felt by simulating the working principle of large battery energy storage equipment. At the same time, through further modification of the graphite felt, the energy efficiency is improved. When the current density is 100mA / cm2, the energy efficiency is greater than 85%; when the current density is 120mA / cm2, the energy efficiency is greater than 84%; when the current density is 160mA / cm2, the energy efficiency is greater than 85% When it is more than 82% and 240mA / cm2, it is more than 80%. The main technical parameters are coulomb efficiency, energy efficiency, voltage efficiency and so on.
