PURPOSE:To meet the recent social requirements for such as global embironmental protection, no pollution, etc., by forming a battery with compositions that are harmless and safe to human body. CONSTITUTION:An electrolyte 12 stored in a storing device 11 is composed mainly of a solution made by mixing glycol system organic matter (such as triethylene glycol, polyethylene glycol, etc.) with water, and a salt to give ion conductivity (such as lithium chloride) is added to the solution. The mixing ratio of the water contained in the electrolyte 12 is preferably 40 to 80%. Also a positive pole 13 formed with a graphite plate and a zinc plate negative pole 15 laminated on both sides of the positive pole 13 through a spacer 14 of nylon net are immersed in the electrolyte 12. A battery thus obtained plays a role for the water in the electrolyte 12 to promote electrode reaction so as to increase current, and also plays a role for the glycol organic matter to enable charging. Then it can be used as a secondary battery. |
