Abstract
The utility model belongs to the technical field of nickel-metal hydride batteries and provides a cylindrical nickel-metal hydride battery and a cathode thereof. The cylindrical nickel-metal hydride battery comprises an anode, the cathode and a cylindrical casing, one surface of a substrate of the cathode is provided with a blank area without adsorbing active substances, and the blank area clings to the inner wall of the cylindrical casing. The cylindrical nickel-metal hydride battery and the cathode thereof increase utilization rate of active substances, save battery cost and battery inner space, reduce batter inner voltage, decrease contact inner resistance between the cathode and the steel casing, and enhance battery charging and discharging property.
Description
Technical field
The utility model relates to Ni-MH battery, relates in particular to a kind of cylinder Ni-MH battery and negative pole thereof.
Background technology
Traditional ni-mh negative pole is all enclosed active material, such negative plate on the whole substrate, two kinds of defectives are arranged, the one, to reel behind the shell, negative pole is close to the active material of box hat, outside not bag is anodal, directly touches box hat, and this part active material is not utilized substantially; The 2nd, have the gap between the active material, between the active material with box hat to contact internal resistance big, increase the polarization of electrode reaction, be unfavorable for battery charging and discharging.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cylinder Ni-MH battery and negative plate thereof that improves the cell active materials utilance and improve the battery charging and discharging performance is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cylinder Ni-MH battery comprises positive pole, negative pole and cylindrical shell, and the one side of the matrix of described negative pole is provided with the not white space of attached active material, and this white space and cylindrical shell inwall are close to.
The length of described white space equates with the interior girth of described cylindrical shell.
On the other hand, the utility model also provides a kind of negative pole of cylinder Ni-MH battery, and the one side of its matrix is provided with the not white space of attached active material.
The length of described white space equates with the interior girth of described cylindrical shell.
The utility model negative pole manufacture method can be when negative pole be enclosed active material, and powder mould in the adjusting realizes that the segmentation of negative pole matrix part encloses active material.Also can after enclose active material, the negative pole matrix active material of corresponding matrix section be wiped off realize again.
The beneficial effects of the utility model: improve active material utilization, the conserve batteries cost, the conserve batteries inner space reduces inner pressure of battery, reduces the internal resistance that contacts of negative pole and box hat, the charge-discharge performance of raising battery.
Description of drawings
Fig. 1 is the cutaway view according to the negative pole of the cylinder Ni-MH battery of the utility model preferred embodiment.
Fig. 2 is the utmost point group coiling schematic diagram according to the cylinder Ni-MH battery of the utility model preferred embodiment.
Embodiment
Embodiment 1
Referring to Fig. 1 and Fig. 2, a kind of negative pole comprises matrix 2 and appended active material layer 1 thereof, is provided with the not white space 3 of attached active material on the one side of matrix 2, and the length of white space 3 is L1.
Use above negative pole to make the 50AA2300 size battery, shell is the cylinder box hat.Box hat internal diameter 13.8mm, the negative pole matrix length L 1=13.8mm*3.14=43.3mm of attached active material not, negative pole size 125mm*44mm*0.30, negative pole enclose the amount 9.8g/ sheet of active material.Behind the active material of one side through the matrix of wiping 43.3mm length off, the actual amount 8.1g/ sheet of enclosing active material of negative pole, the amount of active material reduces=(9.8-8.1/9.8) * 100%=17.3%.Matrix adopting punching nickel plated steel strip after the negative pole starching, before the oven dry, is wiped the active material of the one side of the matrix of 43.3mm length off, and through oven dry, section rolls, and is made into negative plate.The positive pole of appropriate mix, barrier film and some are assisted a ruler in governing a country material, are made into the 50AA2300 size battery, and white space 3 is close to the box hat inwall.
Embodiment 2
Use traditional handicraft to make the 50AA2300 size battery.
Battery steel shell internal diameter 13.8mm, negative pole size 125mm*44mm*0.30, negative pole enclose the amount 9.8g/ sheet of active material.
Use the negative pole wet processing, matrix adopting punching nickel plated steel strip is made into negative plate.The positive pole of appropriate mix, barrier film and some are assisted a ruler in governing a country material, are made into the 50AA2300 size battery.
Adopt this area conventional method, the battery of embodiment 1 and embodiment 2 is done contrast test, test result is as shown in table 1.
Table 1
From above contrast test result, use battery of the present utility model, save negative pole amount 17.3%, inner pressure of battery is lower, and internal resistance is lower, and discharge platform is higher.Other electrical property is more or less the same.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, do not breaking away under the prerequisite of the utility model design, make concrete change or change and all belong to protection range of the present utility model.
