A solid-state cathode for a solid-state electrochemical cell includes an electrochemically active cathode material and one or more elemental dopant residing in grain boundaries of the electrochemically active cathode material. The grain boundaries contain at least 0.2 wt % of the one or more elemental dopant and the one or more elemental dopant is less than 10 wt % of the solid-state cathode. The solid-state cathode does not have liquid, gel and polymer materials.

A gas monitor apparatus includes a sorbent material that adsorbs a target gas based on a concentration of the target gas in a monitored environment and a reference material that does not respond to the target gas. The gas monitor also includes a first thermistor disposed within the sorbent material and a second thermistor disposed within the reference material, the first thermistor to provide a first indication of a first temperature of the sorbent material and the second thermistor to provide a second indication of a second temperature of the reference material. A processing device determines a concentration of the target gas based at least in part on a differential measurement between the first temperature and the second temperature.

Gas sensors for the detection of rare events consume very little or no power. The sensors include materials that interact with a target gas. Accumulation of the target gas on the sensor materials leads to a change in electrical properties of the sensor. The sensors may have high gain, meaning that a large electrical change is induced upon gas accumulation. The sensor might change from an extremely high resistance (open circuit) to a measurably low resistance, or it might change from a relatively low capacitance to a high capacitance. The gas sensors are connected to electronics that can transmit an alarm signal after gas has been detected. The electronics may be in a low power sleep mode until awakened by a signal from the sensor.
