Technical field

Embodiments of the present invention relate generally to electrode material for battery and battery substrate, battery, color using it Plain sensitized solar cell, capacitor, Li ion secondary battery.

Background technique

It is gazed at using the solar battery of sunlight as clean electric energy.As solar battery, monocrystalline is used The solar battery of silicon substrate or polycrystalline silicon substrate is mainly used because its generating efficiency is excellent.In addition, in order to reduce Cost is also being inquired into and is being used the film-form amorphous silicon of silicon substrate filming.In addition, as the solar energy other than these silicon systems Battery, it is also well-known using the group compound semiconductor system solar battery of gallium, arsenic, phosphorus, germanium, indium etc..

The synthesis technology of the enlargement or compound of silicon substrate of the solar battery so far because receiving sunlight Complicated and high production cost, so there are problems that being not easy to carry out universal etc.On the other hand, to reduce production cost as mesh , it is promoting on light absorbing layer (photoelectric conversion layer) using the exploitation of the organic system solar battery of organic compound.In In organic system solar battery, the exploitation of the dye-sensitized solar cell using pigment is being expected.

In addition, the electricity generation systems such as thermal power generation, wind-power electricity generation, nuclear electric power generation can make headed by solar battery Electricity, but electric power cannot be stored.Therefore, promote constructing for the system for capableing of electric power storage critically important.One as the system for capableing of electric power storage A example has the various examples such as Li ion secondary battery, capacitor.For example, in special open 2006-261008 bulletin In (patent document 1), various metal oxides are used for positive electrode or negative electrode material.Li ion secondary battery etc. using Li from The material that the battery of son is awarded in positive electrode or negative electrode material using that can carry out Li ion.

Summary of the invention

Problems to be solved by the invention

Dye-sensitized solar cell, Li ion secondary battery etc. it is common be Li ion.That is, as electrode for cell material Material, it is desirable that effectively carry out the material that Li ion is awarded.But material so far characteristically not necessarily meets, just It is requiring further to improve.

Project to be solved by this invention is, provides electrode material for battery, as electrode material for battery, Li by Ability height is awarded, Li ion exchange can be effectively performed, so can reduce internal resistance.
