摘要： A compact electrochemical gas sensor for detecting toxic gases is described which utilizes a fluted electrically-conducting feedthrough for making the electrical connection from outside the sensor with each electrode inside the sensor. Utilization of the fluted electrically-conducting feedthroughs significantly reduces the number of parts needed to make the sensor as well as reduces the likelihood of electrolyte leakage from the sensor. Additionally, the electrochemical toxic gas sensor may use a gas permeable membrane instead of a gas porous membrane.

摘要： Accordingly, the present invention provides an electrochemical sensor comprising at least two electrochemically active electrodes, a non-aqueous electrolyte system and a diffusion barrier membrane through which the analyte in its gas phase is mobile but through which the non-aqueous electrolyte system is substantially immobile. The diffusion barrier membrane thus allows an analyte in its gas phase to enter the sensor, while substantially preventing the non-aqueous electrolyte from exiting the sensor.

摘要： An active primary battery containing a lithium anode; an aprotic organic electrolyte; a separator; and a cathode made of silver (II) oxide, mercuric oxide, or a mixture of silver (II) oxide and mercuric oxide is described. The battery exhibits high open circuit and operating voltage under a wide range of current densities. The open circuit voltage of a lithium-silver (II) oxide battery of the present invention is almost double that obtained in a zinc-silver (II) oxide battery. The packaged capacity density, in amp-hrs/cc, is about twice that obtained in a lithium-manganese dioxide battery or a lithium-iodine battery. The packaged energy density, in watt-hours/cc, is also about twice that obtained in a zinc-silver (II) oxide battery, a lithium-manganese dioxide battery, and a lithium-iodine battery.
