Abstract
The invention provides a negative plate for battery and a battery containing the same. A traditional lead carbon battery negative plate has severe hydrogen evolution phenomenon and the lead carbon battery has poor cycle life. The negative plate provided by the invention consists of a grid and a negative electrode material filled on the grid. The negative electrode material includes 55-60 wt.% of lead, 35-38 wt.% of high specific surface area carbon, and 0.6-2 wt.% of an additive. The blended paste paints on both sides of the grid, and sulfuric acid immerses for mixed curing; the cured negative plate is put into sulfuric acid for exteriorization; and the prepared negative plate and a PbO2 positive electrode are assembled into a lead carbon battery. The specific surface area of carbon material provided by the invention is greatly improved, so that conductive network forms on the surface of the negative plate and the cycle life of the electrode plate is greatly improved.
Description
Technical field
The present invention relates to a kind of plumbous carbon battery, relate in particular to a kind of electrokinetic cell of new energy vehicle, belong to electrochemical kinetics technical field.
Background technology
In recent years, plumbous carbon battery applies to new energy vehicle, as fields such as hybrid vehicle, electric bicycles, has simplified the circuit of electrokinetic cell.So-called plumbous carbon battery, a kind of difunctional energy-storage battery that had not only there is capacitance characteristic but also there is battery behavior that is that in Asymmetric Supercapacitor and lead-acid battery are adopted, parallel way is combined, by the Carbon Materials with capacitance characteristic, discharged or received current, suppress " the negative pole sulfation " of traditional lead acid batteries.
Visible common plumbous carbon battery, when the addition of material with carbon element is 0.2%～2%, does not also have the effect of super capacitor, and the membership that adds of material with carbon element aggravates negative pole liberation of hydrogen problem, makes storage battery dehydration serious, reduces the cycle life of plumbous carbon battery.Industry expectation is a kind of to be had compared with the appearance of the plumbous carbon battery of long circulation life.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of plumbous carbon battery and negative plate thereof, to solve the poor problem of serious, the plumbous carbon battery cycle life of negative plate hydrogen evolution phenomenon.
For achieving the above object, the invention provides a kind of negative plate of battery, by grid and full-filling, the negative material on described grid forms, it is characterized in that, described negative material is included as 55% ~ 60%(percentage by weight) lead, 35% ~ 38%(percentage by weight) high surface area carbon, 0.6% ~ 2%(percentage by weight) additive.
Preferably, above-mentioned additive is 2%(percentage by weight) conductive black XC72.
According to another aspect of the present invention, provide a kind of battery.This battery comprises above-mentioned negative plate.
Preferably, above-mentioned battery is plumbous carbon battery.
Embodiment
1, the preparation of the present invention and negative plate thereof
By 60% lead, 38% high surface area carbon, 2% conductive black XC72 mix, utilize the mode of manual pasting to be coated in grid two sides the lotion of becoming reconciled, the sulfuric acid that immerses density 1.26g/cm3 is mixing cured under certain process conditions, and all negative plates that solidified are changed into 18 h at home and abroad at the sulfuric acid of 1.06 g/cm3.Make the negative plate of plumbous carbon battery.
The negative plate making is anodal with PbO2 again, according to factory technics, is assembled into the plumbous carbon battery of 6V4.5Ah.
2, overall performance test of the present invention
(1) charge acceptance test
The charge acceptance test program that this experiment adopts is as follows:
(a) complete completely charged storage battery is under the condition of 25+5 ℃, with Ia current discharge 5 h (Ia=Ca/10 (A)); Ca is the maximum in capacity test;
(b) after electric discharge finishes, immediately storage battery is put into temperature and is low temperature chamber 20～25 h of 0 ± 1 ℃;
(c) storage battery takes out in 1 min in low temperature chamber, with constant voltage 14.4+ 0.1 V charging, after 10 min, records charging current value In;
(d) ratio of charging current In and discharging current Ia should be not less than 2.0.
Its test result demonstration, the carbon black adding in negative electrode active material can form good conductive network in lead/lead sulfate particle, thereby can improve the charge acceptance of battery.
(2) cycle life test
Constant current 2.5C, final voltage is 4.8 V, carries out cycle life test at 25 ℃.Can find out, plumbous carbon battery cycle life reaches 1200 times, and when visible the present invention brings up to 3 times of basic consumption and 10 times by content of carbon black in common lead carbon battery negative plate, negative plate hydrogen evolution phenomenon is effectively alleviated.
The specific area of Carbon Materials of the present invention improves greatly, makes the surface of negative plate form good conductive network, and pole plate cycle life obtains larger raising.
