Description

Detailed Description of the Invention

Industrial application fields

The present invention relates to rapid charging / discharging of secondary batteries and improvement of conversion efficiency of solar batteries.

In order to shorten the charging time of the conventional secondary battery and to improve the power generation efficiency of the solar battery, the inventors have not considered strengthening the internal electric field that brings about the improvement of ion and electron mobility.

Problems to be solved by the invention

Even with the highest performance battery charger, the required charging time is 20 to 30 minutes, which is too long compared to gasoline injection, and the improvement of the power generation efficiency of the solar cell is approaching its limit.

Means for solving the problem

In the secondary battery, solar battery, etc., an external electrode that is further insulated is provided on the outside of both conventional electrodes, and another DC static voltage is imposed on the external electrode to superimpose it on the conventional internal electric field. To improve the ability to shorten the charging time and increase the discharge current. In this case, the internal electrodes are opened in a lattice shape so that the superimposed external electric field can penetrate into the battery.
In order to significantly reduce the time required for charging the “A” secondary battery, in order to further increase the electric field to the conventional electric field (E1) due to the charging voltage, an insulating layer is formed on the outside of both electrode foils. New electrode foils (1) sandwiching (2) are provided, and the electric field (E2) is superimposed on (E1). (FIG. 1) For this purpose, both positive and negative electrode foils (3) of a conventional secondary battery are provided with a grid-like window so that an electric field is transmitted, and an insulating layer (2) is provided outside them. A new electrode foil (1) is overlaid, and an insulating layer (2 ') is further provided on the outer side thereof. A DC static voltage branched from a separate power source or charger is applied to both the outermost electrode foils (1). Further, a DC electric field is further superimposed from the outside on the movement of ions and the like in the electrolyte by the charging electric field, thereby greatly increasing the movement speed of the ions and shortening the charging time. These grid-like electrodes and the insulating layers of the openings are respectively made of a cathode-like active material (4) such as graphite for the grid-like negative electrode foil and an anode active material (such as a lithium superionic conductor) for the grid-like positive electrode foil. 7) Bonded and integrated. The insides of both of these lattice foils satisfy LiBH4 * LiI, Li2S, etc., which are solid polymer electrolytes, with a separator interposed therebetween. At the time of discharge, the polarity of the outermost electrode foil (1) is reversed to increase the discharge current and accelerate the speed of the electric vehicle or the like. In this way, the high-speed charger for charging the secondary battery is also quite inexpensive. In addition to the above, it can also be used for hybrid capacitors currently under development.
“B” An example of a silicon solar cell that aims to improve power generation efficiency among various types of solar cells will be described. (Fig. 2) The structure shows that the internal electric field generated near the boundary between the p-type and n-type semiconductors is further strengthened by applying an external acceleration field from the outside to superimpose the electrons generated by sunlight. A part of the holes stays in the battery, so that all of the holes cannot be taken out and become heat so that energy is lost. This is improved by increasing the moving speed. In order to improve the power generation efficiency, a non-reflective coating (8) is applied to the outermost part, a new transparent electrode layer (9) is provided so that electric power can be applied from the outside, and the upper electrode (11) is insulated inside. A transparent insulating layer (10) is provided. The inside is configured in the order of an n-type silicon layer (12), a p-type silicon layer (13), a lower electrode (14), and a base (15) in the same manner as the configuration of a conventional solar cell.

Action

When manufacturing lithium ion secondary batteries, etc., both conventional electrodes are made into grid-like window-permeable electrodes that transmit an electric field, an insulating layer is provided outside them, and a new electrode foil is further placed outside them, and in addition, outside of them. An insulating layer is provided. In this way, a DC static voltage or a DC static voltage branched from the charging power source for applying a new structure to the outermost layer electrode and superimposing it on the internal electric field is applied to the outermost layer electrode. Also in the solar cell, a transparent electrode layer (9) newly provided with an antireflection coating is newly provided on the outermost layer, and the comb-shaped window-shaped electrode is insulated by the transparent insulating layer (10) therein. A DC static voltage is imposed on the new transparent electrode layer (9), and the electric field is superimposed and strengthened on the conventional internal electric field.

effect

When the secondary battery has such a structure, charging can be performed in the shortest time only by applying a charger and a DC electrostatic voltage branched therefrom. Similarly, a reverse voltage can be applied during discharge to increase the discharge current, and the speed of the electric vehicle can be accelerated rapidly. This fast charger is also quite inexpensive. Even in a solar cell, this superimposed electric field improves the mobility of ions and electrons, reduces thermal energy loss due to their retention, and improves power generation efficiency.
