Negative lead paste and electrolyte additives for reducing sulfation of lead-acid batteries

The invention discloses a negative lead paste and electrolyte additives for reducing sulfation of lead-acid batteries, wherein the additional components are metered and added according to the mass percentage. 0.5 to 0.7 percent of benzyl benzoate is added into that negative electrode lead paste on the basis of maintaining the conventional components, and EDTA-Na2 can be added or not added in the matching electrolyte.. Alternatively, no benzyl benzoate can be added to the negative electrode paste, so the electrolyte must be mixed with one of benzyl benzoate and EDTA-Na2.. The addition of benzylbenzoate inhibits the recrystallization of lead sulfate and prevents the crystal growth. Adding EDTA-Na2 to the electrolyte to improve the activity of the built-in active substances, is conducive tothe decomposition of lead sulfate crystals, so as to enhance the conductivity, enhance the battery charge acceptance, play a role in reducing sulfation of lead acid battery, and achieve the purpose ofimproving the battery cycle life.
