The invention provides a battery electrolyte for anacidity ionic state lithium accumulator, which comprises 40.0-60.0%(w / / v) of lithium salts, 0.5-0.8%(w / / v) of EDTA, 0.2-0.4%(v / v) of anti-aging agent 2-sulfhydryl benzimidazole allyl sulfide, 0.2-0.4% (w / v) of anti-oxidizing agent 2, 6-butylated hydroxytoluene, 30.0-35% (v / v) addition agent H3PO4 and distilled water. The accumulators employing the electrolyte can completely avoid the environmental contamination by sulfuric acid.
Description
Technical field [0001] The invention relates to an electrolyte for a storage battery, in particular to an electrolyte for an acid-free ion state lithium salt battery. Background technique [0002] Lead-acid batteries can be recharged after being discharged and used repeatedly. More than one hundred years have brought immeasurable convenience to the production economy and life of mankind. However, due to the large amount of sulfuric acid used in this type of battery, it pollutes the environment. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a method for effectively avoiding environmental pollution caused by sulfuric acid in the electrolyte of the original lead-acid battery without changing the working mechanism of the original lead-acid battery. Electrolyte for acid-free ionic lithium salt battery. [0004] In order to achieve the above objective, the technical solution adopt...
