РусскийOn the Issue of Heat Emissions in Lithium-fluorocarbon Cells
The power sources of the lithium-fluorinated carbon electrochemical system often fail to withstand forced discharges because of greater heat emission due to ohmic and polarizing losses, which leads to heating at the best, and to destruction of the element and failure of the equipment at the worst. Heat emission from the cells of the lithium manganese–dioxide system at forced discharges is 2–3 times less than from the similar cells of the lithium–fluorinated carbon system. Therefore, adding some amount of manganese dioxide to the carbon fluoridebased cathode material, it is possible to achieve the necessary reduction in heat emission without substantially reducing the capacity. Some reduction of heat emission is also possible due to rational choice of electrolyte. Keywords: fluorocarbonlithium cell, manganese–dioxide, discharge characteristics of the cells.
