Description
Technical field
The present invention relates to storage battery production field, particularly a kind of superbattery is mended the charcoal method.
Background technology
In recent years, lead-acid battery is because of mature production technology, and is cheap, and advantages such as security reliability height have been widely used in the electric motor car industry, and this has also proposed requirements at the higher level to aspects such as its energy density and weight.To these problems, both at home and abroad the expert proposes in negative pole, to add active carbon material and improves lead-acid battery and also propose the notion of superbattery gradually as the application of electrokinetic cell and energy-storage battery, manufactures and designs the storage battery with ultracapacitor.Patent application before the applicant's the legal person, the patent No. is that " 2010102907180 " name of patent application is " superbattery mixing cathode lead plaster and preparation method thereof ", in cathode lead plaster, adds active carbon: 1 ~ 7; In this indication range, if the amount that adds is few, and cream; Stage such as change into because extruding and electric field force effect, after a large amount of losses of the charcoal amount on (especially on the surface), the performance index of negative plate then do not reach designing requirement in the lead plaster; If the amount that adds is big; Not only cause the wasting of resources, change into or charging process in can aggravation negative pole gassing, the air scour effect makes negative electrode active material form micropore; Cause the active material adhesion to descend, have a strong impact on the capacity and the life-span of superbattery.
Summary of the invention
The technical problem that the present invention will solve provides a kind of superbattery and mends the charcoal method; Can overcome and cream; Stage such as change into because extruding and electric field force effect, the problems of a large amount of losses of the charcoal on (especially on the surface) make the carbon content of negative plate not reach designing requirement in the lead plaster.
The present invention realizes through following technical scheme:
A kind of superbattery is mended the charcoal method, it is characterized in that may further comprise the steps:
(1) and cream: form cathode lead plaster, lead powder by following weight portion raw material: 100, sulfuric acid: 4 ~ 10, binding agent: 0.1 ~ 8; Barium sulfate: 0.1 ~ 2, the liberation of hydrogen inhibitor: 0.01 ~ 2, active carbon: 1 ~ 4, out-phase graphite: 0.1 ~ 2; Acetylene black: 0.05 ~ 0.5 (, please examine) with the adjustment that the patent of invention of former application is carried out, humic acid: 1 ~ 4, water: 12 ~ 21; Short fiber: 0.1 ~ 0.2, undertaken and cream by conventional method, and accomplish smear by conventional method;
(2) negative plate behind step (1) smear is solidified under 80 ℃, relative humidity 96% condition be no less than 60 hours;
(3) negative plate after will solidifying changes into, and the time of changing into was not less than 20 hours;
(4) by acid solution cumulative volume in the boric acid pond; In the boric acid pond, add and the identical raw material of wood-charcoal material 0.4 ~ 20% of step (1) cathode lead plaster raw material; After the washing of the negative plate after changing in the step (3), put into and pull out after 10 ~ 20min is soaked in the boric acid pond, send into the drying plant oven dry;
(5) negative plate that step (4) is obtained, the positive plate that makes with the conventional method battery case of packing into.
The further improvement project of the present invention is that said liberation of hydrogen inhibitor is a kind of or two kinds or the two or more mixing in indium oxide, bismuth oxide, stearic acid or the barium stearate.
The further improvement project of the present invention is that described binding agent is mixed by following raw materials in weight portion, organic additive: ethylene-vinyl acetate copolymer: polyvinyl alcohol: water=1:0.1 ~ 0.8:1 ~ 3:15 ~ 20; Said organic additive is a kind of or two kinds or the two or more mixing in polytetrafluoroethylene, butadiene-styrene rubber, the sodium carboxymethylcellulose.
The raw material of wood-charcoal material percentage by weight that step (4) adds is active carbon 60-90%: out-phase graphite 5-30%, acetylene black 1-5%.
The invention has the beneficial effects as follows:
The present invention is applicable to and makes high-powerly that big capacity and the super battery plate that has extended cycle life be as making automobile, and ship power is with pole plate and manufacturing solar energy storage plate of battery etc.Soaking the boric acid stage; In the boric acid pond, add 0.4% ~ 20% with the raw material of wood-charcoal material of paste formulation same size; The raw material of wood-charcoal material can successfully to get into pole plate inner or attached to polar board surface along with flowing of liquid when soaking boric acid; Thereby improve the carbon content of pole plate, be of value to the comprehensive raising of superbattery performance; Advantage of the present invention is in the superbattery cyclic process; The crystallization of negative plate sulfation further diminishes; Help in charging process lead sulfate to the conversion of negative pole spongy lead; Simultaneously tangible material with carbon element coating occurs, thereby make superbattery have higher energy density and longer cycle life at polar board surface.
