摘要： A lithium secondary battery 1 including: an inner electrode member 6 having electrode plates (cathode plate 2, anode plate 3) of a metal foil as a constituting element, and being formed by winding or laminating electrode plates; and a battery case 10 for housing the inner electrode member 6. A gas release channel capable of releasing a gas to the outside of the battery case 10 is formed by deformation of the inner electrode member 6 by a function of a raised inner pressure when the inner pressure of the battery case 10 rises to a predetermined pressure or more due to the gas generated inside the inner electrode member 6. The lithium secondary battery can smoothly release the gas generated inside the inner electrode member without being retained therein before the gas reaches a pressure releasing mechanism; thus, it is superior in safety and has a high energy density.

摘要： A gas sensor for measuring NOx concentration in measurement gas based on sensor output depending on an amount of the detected oxygen includes an oxygen concentration control part for controlling oxygen concentration in the measurement gas. The oxygen concentration control part allows a control of oxygen concentration in the measurement gas to set at a designated value even after being mounted on an automobile, so that dependency of the sensor output with respect to oxygen concentration can be quantitatively detected. The sensor output for detecting NOx concentration is corrected by estimating an amount of a change accompanying the sensitivity degradation of the sensor output with respect to NOx concentration on the basis of a difference between oxygen output characteristics of the sensor output of an actually-used sensor and oxygen output characteristics of a sensor in the initial state, and correcting the sensor output in accordance with the amount of the change.
