Web1.Introduction. Cylindrical lithium-ion batteries are widely used due to the advantages of high performance and stable uniformity [1].When the battery is operating, self-generated heat accumulates [2].Because of the multi-layer winding structure inside the cylindrical battery, the radial thermal conductivity of the battery is much smaller than the axial … WebAn ionization chamber with parallel flat electrodes (disks) is the simplest type. The diameter of the disk is several times greater than the distance between the electrodes. In a cylindrical ionization chamber the electrodes are two coaxial cylinders, one of which is grounded and serves as the housing of the ionization chamber (Figure 1).
