Description

Battery device with discharge site and charge site separated

The present invention relates to a battery system in which charge and discharge sites are completely separated. More particularly, the present invention relates to an apparatus capable of completely separating a charging site from a discharge site to make an electrolyte and an active material charged and then supplying the discharge site.

Large secondary batteries are needed to store power during off-demand times such as at night and use it when power demand is high, or to store power generated by solar cell power generation. Redox polo cells or circulating metal-air cells have been developed. They have separated the charge site from the discharge site to enable large scale charge discharge. However, the redox polo battery or the circulating metal air battery is bulky and heavy, which causes inconveniences and obstacles in transportation.

With the development of batteries, the development of nickel-hydrogen batteries and lithium secondary batteries has made the use of cordless portable devices even more convenient. These batteries are currently used in electric vehicles. However, charging of electric vehicles takes time, which is a limiting factor in the spread of electric vehicles.

The present invention provides a battery in which the discharge site and the charge site are completely separated, not by circulation.

The effect of the present invention is to completely separate the charge site and the discharge site, thereby reducing the weight of using only one site, compared to using both.

Another effect of the present invention is to prepare the electrolyte and the active material in advance in the charging site and to prepare the supply to the discharge site to the electrolyte and the active material it is possible to save the time required to charge the side that needs to be discharged.

Another effect of the present invention is to prepare and store the active material and the electrolyte of the charge site in advance, and economically by calculating the amount of energy obtained from unstable and rough power such as wind power, tidal power, wave power, temperature difference generation, night power, etc. It is to provide a means that can be used equivalently for interchange.
