Abstract
The invention relates to an internal formation process of a super battery. The internal formation process comprises the following major steps: pouring a certain volume of acid solution with certain concentration into a super battery by use of a vacuum method first before formation, standing for 2-4 hours, and carrying out internal formation of the battery in a manner of four charge times and three discharge times with short time and multiple periods by adopting fixed current. Due to the multi-cycle charge-discharge manner, the porosity of a polar plate and the utilization rate of active substances are greatly increased, the influence on concentration polarization and electrochemical polarization is effectively alleviated, the capacitive character of a carbon material in the polar plate can be effectively activated, and therefore, the large current charge-discharge and cycle life properties of the super battery are improved.
Description
Technical field
The present invention relates to plumbic acid and hold chemical synthesis technology, relate in particular to the internal formation process of super accumulator, belong to power vehicle and use battery technology field.
Background technology
Container formation and channelization become to compare, and have many advantages, and its technological process has been simplified pole plate washing, dry and battery and supplemented load that electricity and slot type change into, welds, gets the operations such as sheet.Therefore can save a large amount of man-hours and the energy, need not purchase electrolytic bath equipment and acid-mist equipment, battery becomes instinct to obtain certain reduction.And, pole plate is difficult for being polluted by impurity, can reduce self-discharge of battery, battery quality also can be controlled better, therefore, current most of storage battery producer all starts the Primary Study being internalized into and is suitable for, but battery chemical synthesis technology is not also very ripe, also there are a lot of problems in being internalized into of common lead acid accumulator, for example, is internalized into the time long, active material low conversion rate, combo difficulty etc.
Application number is 201110309249.7 " chemical synthesis technology that a kind of power lead acid battery is internalized into ", this patent is internalized into and total time reaches 100h, become the time suitable with channelization, have a strong impact on production efficiency, in addition, this internal formation process has just solved conversion ratio and the positive plate quality problems of positive plate active matter, does not consider that the quality of negative plate and active material transform situation.
Application number is 200510110534.0 " electric boosted automobile-used container formation process for lead acid storage battery ", this patent is internalized into and total time also reaches 85h, although charging stage current value strengthens the active material problem that comes off that solved gradually in addition, restriction charging voltage has solved liberation of hydrogen and acid mist problem, but this formation charging affects the high rate during charging-discharging of finished product battery, and battery actual capacity do not reach rated capacity, cause battery defective.
Therefore,, if adopt the internal formation process of common batteries to be applied to being internalized into of superbattery, tend to cause change into not exclusively positive/negative plate active material low conversion rate, the problem that battery performance is poor.
