fluorocarbon-lithium cell

On 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.

Increasing the Energy Output of the Fluorocarbon Cathode

Various features of creation of the lithium­-fluorocarbon power sources were considered. The electrochemical characteristics of the electrodes, which were manufactured using various compositions of fluorocarbon and silver vanadate, were studied. It was found that the electrodes based on the mass ratio CFx : SVO 82.5 : 7.5 show the best properties. The composite electrodes have significant advantages in discharge potential, capacity and stability compared with the fluorocarbon ones.

The Prospects of Use of the Fast-Tempered Materials in Current Sources

For the purpose of creation of a reliable current conductor for fluorocarbon-lithium cell with use of the fast-tempered materials the corrosion and electrochemical behavior of microcrystalline AV-86 alloy and also amorphous Ni81P19 and Fe70Cr10P13C7 alloys in electrolytes on a basis γ-butyrolactone (GBL) is studied. The high corrosion resistance and conductivity of amorphous materials do perspective their use as current conductor of current sources.
