A thermal electrochemical cell having a LiAl anode with a salt additive in the range of 10% to 40%, a transition metal fluoride cathode and an alkali metal fluoride salt mixture electrolyte. Preferably, the cathode is CuF and the electrolyte is selected from the group consisting of LiF&mdash;KF, LiF&mdash;KF&mdash;NaF, LiF&mdash;RbF, LiF&mdash;KF&mdash;RbF, LiF&mdash;NaF&mdash;RbF, and LiF&mdash;KF&mdash;RbF.

Anode invention for lithium/transition metal fluoride molten salt cells and batteries

A solid state electrochemical cell comprising:

Thin film lithium polymer battery

In units comprising solid polymer electrolytes, the ionic conductivity of such electrolytes is increased by mechanically exciting the units. Such units can be solid state batteries or electrochromic devices or the like. Mechanical excitation may be provided by, for example, a piezoelectric transducer.

Fast ion conductors

Thionyl chloride cells are deactivated by introducing a solution of aluminum chloride in thionyl chloride into the cell.

Deactivation of thionyl chloride cells

A high rate rechargeable silver-zinc pile type battery including a plurality of bipolar electrodes which are assembled into a full scale multi-cell pile. Each of bipolar electrodes includes a positive side having a porous silver matrix attached to silver foil and a negative side having a porous zinc structure vapor deposited on silver foil. A separator including three different components in layers is disposed between the positive and negative sides of the bipolar electrode. An epoxy adhesive is used to position and retain a seal in its proper location to electrically isolate the individual electrodes and form a cavity for retention of the electrolyte. Intercell connectors of etched silver foil serve as the cell case and active material substrate as well as the series connection between individual cells for electrical continuity.
