Abstract
In a metal negative cell in which the negative electrode mainly comprises a metal such as aluminum, magnesium, zinc, lithium, etc., self discharge readily occurs when the negative electrode and an electrolytic solution are in contact, and the problem of large capacity loss of the cell readily occurs. The metal negative cell is provided with a metal negative cell in which the self-discharge amount is reduced, and the capacity loss of the cell is reduced during use or storage, whereby the metal negative cell varies the cell output according to demand.
Claims17
A metal negative electrode cell having a positive electrode, a metal negative electrode, and an electrolytic solution, the metal negative cell comprising:
- an immersion means for controlling the area of the metal negative electrode immersed in the electrolytic solution at the time of use, by means of which the metal negative electrode is extruded from or pushed back toward the electrolytic solution, or by means of which the liquid level of the electrolytic solution of the metal negative electrode is raised or lowered, varies the immersion length of the metal negative electrode according to demand,
- a separator that separates the electrolytic solution into a positive electrode side electrolytic solution and a negative electrode side electrolytic solution, and
- an electrolyte delivery mechanism for delivering a negative electrode electrolyte to the negative electrode electrolytic solution and/or an electrolyte delivery mechanism for delivering a positive electrolyte to the positive electrolytic solution, whereby the concentration of the negative and/or positive electrolyte solution is controlled.
A metal negative electrode cell having a positive electrode, a metal negative electrode, and an electrolytic solution,
- the metal negative electrode cell comprising:
- means for extruding from or pushing back the metal negative electrode linearly towards the electrolytic solution for controlling the area of the metal negative electrode immersed in the electrolytic solution at the time of use according to demand.
