Provided is a charging method of a secondary battery capable of reducing the irreversible quantity in initial charge and discharge cycles after production of the battery and improving charge and discharge cycle characteristics. The secondary battery is at least comprised of an anode, a cathode, and an electrolyte and has a curve of anode potential or cathode potential against storage quantity, or an open-circuit voltage curve of battery against storage quantity. With inflection points. In carrying out a charging operation of the secondary battery in a predetermined waveform, before arrival at the charging quantity on the inflection point, at least until at least at the charging quantity on the inflection point, the charging current and/or charging voltage is charged during the charging. After passing the inflection point, until full charging state, the charging is performed in a different pattern from that before the inflection point.

摘要:
The object of the present invention is to provide a secondary battery that has a lamination of negative electrodes and positive electrodes with intervening separators that acquires a low battery internal impedance and excellent charging and discharging power by the sufficient compressing of the electrodes, and that is very safe and easy to recycle, and to provide a method for manufacturing such a battery. To achieve the above object, according to the present invention, in a battery wherein positive electrodes and negative electrodes are disposed with intervening separators, and are stored in a battery case with a solid electrolyte or an electrolytic solution, provided in the battery case is a member whose shape is changed at a predetermined temperature (first temperature), which is lower than the melting point of the separator and which falls outside the battery operating temperature range, that maintains the shape in the battery operating temperature range. By heating or cooling the member to the first temperature, pressure is applied to at least one part of the battery case or the applied pressure is released.
摘要:
A process for the formation of a functional deposited film as a thin semiconductor film constituted with the group IV element or a thin semiconductor film constituted with group IV element alloy, by introducing, into a film forming space (116), a compound as the film-forming raw material and, if required, a compound containing an element capable of controlling valence electrons for the deposited film as the constituent element each in a gaseous state, or in a state where at least one of the compounds is activated, while forming hydrogen atoms in an excited state causing chemical reaction with at least one of the compounds in the gaseous state or in the activated state in an activation space (114) different from the film forming space and introducing them into the film forming space, thereby forming a deposited film on a substrate (118), wherein the hydrogen atoms in the excited state are formed from a hydrogen gas or a gas mixture composed of a hydrogen gas and a rare gas by means of a microwave plasma generated in a plasma generation chamber disposed in a cavity resonator (101) integrated with two impedance matching circuits in a microwave circuit and the excited state of the hydrogen atoms is controlled.
