Definitions
- the present invention relates to a method for producing an all-solid secondary battery.
- a secondary battery and a capacitor as a device having a power storage function.
- a secondary battery is a device utilizing a chemical reaction and is characterized by a large capacity.
- a capacitor is characterized in that it can be charged in a short time because it accumulates electric charges with an insulator sandwiched between electrodes.
- Secondary batteries include nickel / cadmium batteries and lithium ion secondary batteries.
- Examples of the capacitor include a super capacitor (also called an electric double layer capacitor) and a MOS capacitor.
- a lithium ion secondary battery which is a typical secondary battery, has a three-layer structure in which a separator is sandwiched between a positive electrode and a negative electrode, and these components are covered with an electrolyte that can flow lithium ions.
- the positive electrode and the negative electrode are materials capable of absorbing and releasing lithium ions and electrons, and charging / discharging is performed as lithium ions travel between the positive electrode and the negative electrode through the electrolyte inside the lithium ion battery.
- Patent Document 1 The structure disclosed in Patent Document 1 as a laminated structure of a solid lithium ion secondary battery includes a positive electrode layer having a positive electrode active material in and out of lithium ions, a negative electrode layer having a negative electrode active material in and out of lithium ions, and a positive electrode A solid electrolyte layer disposed between the layer and the negative electrode layer.
- the solid electrolyte layers of two adjacent stacked bodies are connected by an insulating layer. Furthermore, two adjacent laminated bodies are laminated so that the negative electrode layers constituting each laminated body or the positive electrode layers constituting each laminated body 4 are in contact with each other.
- Patent Document 2 discloses a quantum battery as a secondary battery based on a new principle. “Quantum battery” is the name given to the secondary battery disclosed in Patent Document 2.

Abstract
Description
その方法は、第一電極12、n型金属酸化物半導体層14、充電層16、中間絶縁層18、p型金属酸化物半導体層22と第二電極24とを、この順序に積層した後に、この積層体を35~65パーセント以内の湿度の環境内に配置させる。次に、第一電極12と第二電極24の間に、電圧源から正電圧と0Vのサイクル電圧繰り返し印加する方法、及び電圧源から正電圧と負電圧のサイクル電圧繰り返し印加する方法である。以下、混在層を電気的に形成する方法を詳細に説明する。
図2は、正と0Vのサイクル電圧印加前後の酸化物半導体二次電池10の構造を示す。
以下、混在層20を備える酸化物半導体二次電池10の製造方法を、フローチャートを用いて詳細に説明する。
図4は、サイクル電圧印加システムの実施回路の一例を示す。
図5は、正と0Vの電圧波形40-1の一例を示す。
酸化物半導体二次電池10の作製にあたっては、絶縁性物質であるガラスを基板とした。まず、第一電極12は、クロムをターゲットとしてスパッタデポジション法を用いて、100~300nmの膜厚で成膜した。製造装置としては、RFスパッタリング装置を用いた。なお、第一電極12は電流を流しやすくするため、例えば、100μΩ・cm以下の抵抗率を有する材料とすることが好ましい。
