Patent ID: 8119276

Claim:
An electrochemical power system, which consists of: a) a first primary cell comprising: i) a first casing; ii) an anode comprising lithium; iii) a cathode current collector; and iv) a catholyte comprising an inorganic depolarizer solvent provided with a halogen or an interhalogen dissolved therein to activate the anode and cathode current collector housed inside the first casing; b) a second lithium ion cell comprising: i) a second casing; ii) a negative electrode of an anode material that intercalates and deintercalates with lithium and is contacted to an anode current collector; iii) a positive electrode comprising a cathode active material that intercalates and deintercalates with lithium and that is contacted to a cathode current collector; and iv) an electrolyte activating the negative and positive electrodes of the second rechargeable cell, housed inside the second casing; and c) wherein the first and second cells are electrically connected in parallel, and d) wherein a first open circuit voltage of the first primary cell in a freshly built state is greater than a second open circuit voltage of the second lithium ion cell in a fully charged state.
