preparation example Construction

[0046] The present invention also provides a method for preparing the above-mentioned lead-carbon battery for motorcycles, comprising the steps of:

[0047] (1) Grid casting: Heat and melt the positive grid alloy and negative grid alloy at 480-510°C, and cast them with positive and negative grid casting machines. The cast grids need to be age-hardened for more than 72 hours Only then can it be used for coating; among them, the thickness ratio of the positive and negative grids is 1:0.80, which ensures that the amount of active materials on the positive and negative plates is scientifically and reasonably matched;

[0048] (2) Preparation of lead paste:

[0049] Preparation of positive lead paste

[0050] Take the lead powder, short fiber and high-purity graphite in the above parts by weight, pour them into the positive electrode and paste machine, add pure water after dry mixing for 3-5 minutes, stir for 2-3 minutes, and then slowly add dilute Sulfuric acid, control to add d...

Abstract

The invention discloses a lead-carbon battery for a motorcycle. The lead-carbon battery comprises positive grid, a positive lead plaster coated on the positive grid, a negative grid and negative lead plaster coated on the negative grid, wherein the positive lead plaster is prepared from the following raw materials in parts by weight: 100 parts of lead powder, 9-10 parts of dilute sulfuric acid which is 1.400 in density, 0.02-0.03 part of short fiber, 0.15-0.3 part of graphite and 13-14 parts of purified water; and the negative lead plaster is prepared from the following raw materials in parts by weight: 100 parts of lead powder, 0.95-1.15 parts of expanding agent, 1-4 parts of complex carbon material, 7-8 parts of dilute sulfuric acid which is 1.400 in density, 0.015-0.025 part of short fiber and 11-14 parts of purified water. The positive and negative active substance utilization ratio of the prepared lead-carbon battery for the motorcycle is increased by 15-25 percent in comparison to a conventional battery. When the battery is started for discharging at large current at the multiplying power of 8-10 times, the output power is stable.

Description

technical field [0001] The invention relates to the field of chemical power sources, in particular to a lead-carbon battery for motorcycles and a preparation method thereof. Background technique [0002] For more than 100 years, lead-acid batteries have occupied an absolute position in the field of secondary power sources for a long time due to their stable performance, low price and recyclable metal resources. The ion battery challenge. Lead-carbon super battery is a new type of power source introduced by Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO) and Japan's Furukawa Corporation for the first time in the world. It combines the technical advantages of batteries and super capacitors, making the ratio of lead-acid batteries Energy and cycle life have been improved breakthrough. This kind of lead-carbon super battery has achieved great success as a power battery test on electric vehicles. The industry agrees that lead-carbon super batter...
