Abstract: An electrochemical cell having a lithium or lithium alloy anode, a solid cathode, and a nonaqueous, liquid electrolyte, includes an amount of a potassium salt which is effective to lower the open circuit voltage of the cell without causing any significant detrimental effects such as corrosion of the anode or self discharge of the cell. More specifically, the electrolyte comprises one or more organic solvents, an electrochemically active amount of one or more primary salts, and more than about 0.001 mol/l of one or more potassium salt additives which achieve the desired open circuit voltage without any harmful effects on the cell. The potassium salt additives have also been found to enhance load voltage on the first 50% depth of discharge, indicating improved rate performance.

Abstract: A rechargeable flashlight is provided comprising in combination a tubular housing open at one end and closed at an opposite end. An integral lamp assembly and power supply circuit are slidably received within the tubular housing. An electrical connector is provided at the closed end of the tubular housing to selectively interconnect the power supply circuit to an external electrical power source, such as an AC socket, to recharge the battery. In a second position, the electrical connector is disconnected from the power supply circuit, and power is provided by the rechargeable battery. The open end of the tubular housing is closed by a removable lens assembly, concentrically receiving a lamp extending from the integral lamp assembly, for organizing the light produced by the lamp into a beam.
