Embodiment 1

[0021] A lead-acid storage battery is internally formed into a composite paste. The percentages of each chemical component in the positive electrode composite paste to the mass of the positive electrode composite paste lead powder are: 8%~9% of dilute sulfuric acid with a concentration of 35%~43%, and 11%~ of deionized water. 13%, tin oxide or stannous sulfate 0.05%~0.4%, colloidal graphite or conductive graphite 0.15%~0.4%, short fiber or polyester fiber 0.04%~0.1%, basic lead sulfate powder 1%~2%, sulfuric acid Lead powder 1%~2%; the percentages of the chemical components in the negative electrode paste to the mass of the negative electrode paste lead powder are: 7.5%~9% of dilute sulfuric acid with a concentration of 35%~43%, and 10%~12% of deionized water , acetylene carbon black 2%~4%, sodium lignosulfonate 2%~4%, barium sulfate 8%~14%, short fiber or polyester fiber 0.04%~0.1%, humic acid 2%~4%, Magnesium sulfate 0.1%~0.2%.

Abstract

The invention provides a composite paste for an inner formation of a lead-acid storage battery. Positive composite paste lead powder comprises the following chemical components of a positive composite paste in percentage by mass: 8%-9% of 35%-43% dilute sulphuric acid, 11%-13% of deionized water, 0.05%-0.4% of tin oxide or stannous mono-sulphate, 0.15%-0.4% of colloidal graphite or conductive graphite, 0.04%-0.1% of a short fiber or polyester fiber, 1%-2% of basic lead sulphate powder and 1%-2% of lead sulfate powder; and negative composite paste lead powder comprises the following chemical components of a negative composite paste in percentage by mass: 7.5%-9% of 35%-43% dilute sulphuric acid, 10%-12% of deionized water, 2%-4% of acetylene carbon black, 2%-4% of sodium lignosulphonate, 8%-14% of barium sulfate, 0.04%-0.1% of the short fiber or polyester fiber, 2%-4% of humic acid and 0.1%-0.2% of magnesium sulfate. By the technical scheme, the initial capacity of the lead-acid storage battery can be significantly improved; and the lifetime of the battery can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries, and in particular relates to a lead-acid storage battery internally forming a composite paste. Background technique [0002] With the increasing number of electric bicycles, electric tricycles and electric vehicles on the market, the demand for batteries of various types of electric vehicles has also increased. The batteries can be divided into internal and external batteries. The grids used in external batteries contain antimony and cadmium. , internalized into the grid used contains calcium. Nowadays, the voice of banning cadmium is increasing day by day. The government has also formulated a ban on cadmium until the end of 2013 and strict requirements for the production of lead-acid batteries. Therefore, lead-acid batteries must be transformed from external to internal. Containing cadmium, however, the existing internalized lead-acid batteries on the market have problems su...
