An electrochemical cell comprises a cathode, a Li anode, a thionyl chloride depolariser and an electrolyte salt. The cathode is carbon mixed with a polymeric Co phthalocyanine complex and is heat treated at a temp. of at least 500 deg.C. Pref. the amt. of complex used is 0.5-20 esp. 2-10 wt.% w.r.t. carbon and the cathode consists primarily of carbon esp. Shawinigan C-black. The cell is pref. made by heating the mixt. at a temp. of at least 500 deg.C for at least 2 hrs., cooling, forming a slurry with a non-aq. liq., and shaping into a cathode. The slurry pref. contains a binder esp. 'Teflon' (RTM) powder or emulsion. The cell has higher voltage at large discharge currents and low temps. The specific cathode capacity was improved esp. at low temp. discharge. |
