Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a colloidal electrolyte storage battery, and also relates to a manufacturing method of the colloidal electrolyte storage battery. Background technique [0002] In the prior art, the batteries currently used are still mainly ordinary lead-acid batteries, because the configuration method is simple and the cost is low. However, when lead-acid batteries use lead-acid electrolytes during charging or leakage, etc., acid mist is precipitated, which is harmful to human health and pollutes the environment; lead-acid electrolytes are corrosive and will corrode equipment; and because lead-acid electrolytes have Volatility will cause the active material and acid reaction ability of the positive and negative plates to decrease, resulting in short storage period when charged, serious self-discharge and other problems. [0003] In order to adapt to higher environmental protection req...
