| 摘要 |
A primary electrochemical cell having a capacity in excess of 0.5 AHr and a high energy density anode comprised of a metal selected from lithium, sodium, potassium, calcium and manganese and a cathode active material, wherein the discharge capacity of the anode is at least substantially equal to or in excess of the discharge capacity of the cathode active material, and wherein said cell further comprises a voltage monitor and cell circuit cut-off whereby when the voltage monitor senses a discharge voltage of about 1.6 or lower, said circuit cut-off are actuated to cut off the cell circuit to thereby prevent hazardous conditions of cell reversal or anode metal plating.
