摘要:
A method for detecting the charged state of a battery based on the measurements of open circuit voltage in which the charged state of a battery can be detected precisely regardless of the degradation state of the battery. Internal impedance of a battery is measured, voltage of the battery is measured under stable state, measurement of the battery voltage under stable state is subjected to raising correction depending on the measurement of internal impedance, and then charged state of the battery is determined based on the corrected value of battery voltage under stable state.

A graphite substrate is processed to have surface unevenness in a range of 1 μm to 8 μm. Thereby, a semiconductor film to be laminated on the graphite substrate has a stable film quality, and thus adhesion of the graphite substrate and the semiconductor layer can be enhanced. When an electron blocking layer is interposed between the graphite substrate and the semiconductor layer, the electron blocking layer is thin and thus the surface unevenness of the graphite substrate is transferred onto the electron blocking layer. Consequently, the electron blocking layer also has surface unevenness approximately in such range. Thus, almost the same effect as a configuration in which the semiconductor layer is directly connected to the graphite substrate can be produced.
