Embodiment 1

[0026] Example 1 Alkaline accumulator, comprising Ti positive plate, Ni negative plate and NaOH solution conductive liquid, the pH value of the conductive liquid is 8.50, the thickness of the Ti positive plate and Ni negative plate are respectively 0.8mm, positive plate, The volume ratio of negative plate and conductive liquid is 1:1:2.8.

[0027] This example alkaline storage battery is prepared like this:

[0028] After the Ti positive plate and the Ni negative plate with a thickness of 0.8mm and an area of ​​10×35mm are electroactivated, the asbestos separators are placed on both sides of the asbestos separators with a distance of 0.8mm, and then filled with NaOH with a pH of 8.5 Solution 784mL.

[0029] The capacity of the alkaline storage battery in this example is 200Ah, and the charging time is 1 hour and 10 minutes. The charging time is short and the charging speed is fast.

Embodiment 2

[0033] Examples 2-5 Alkaline storage battery, the area of ​​the Ti positive plate and the Ni negative plate are both 10×35 mm, and other parameters are shown in Table 1.

[0034] Table I

[0035]

[0036] In order to facilitate the test, the areas of the Ti positive plate and the Ni negative plate of the alkaline storage battery in Examples 1-5 are 10×35mm. In actual production, those of ordinary skill in the art can increase or decrease according to the needs of different battery capacities. The area of ​​the electrode plate is used to obtain an alkaline storage battery with a larger or smaller capacity.

Abstract

The invention discloses an alkaline storage battery, which comprises a positive plate, a negative plate and a conductive solution. The positive plate is a Ti positive plate, the negative plate is an Ni negative plate, and the conductive solution is an alkaline conductive solution. The alkaline storage battery disclosed in the invention adopts the Ti plate characterized by low electric potential, corrosion resistance and high conductivity as the positive plate, and takes Ni as the negative plate, thus increasing the potential difference between the positive electrode and the negative electrode, and improving the charging speed of the alkaline storage battery provided in the invention. The alkaline storage battery of the invention employs environment-friendly Ti as an electrode material, and solves the environmental protection problem that current nickel-cadmium alkaline storage batteries can cause cadmium pollution on the environment. Further, when conducting waste treatment on the alkaline storage battery of the invention, no complicated recycling operation is needed, and an electrode plate recovered material can be used as a soil fertilizer. The alkaline storage battery provided in the invention uses low cost Ti as the electrode plate so as to have a reduced production cost, which is reduced by about 40% compared with the current nickel-cadmium alkaline storage batteries.

Description

technical field [0001] The present invention relates to accumulators, in particular to alkaline accumulators. Background technique [0002] Nickel-cadmium alkaline storage battery is one of the most common storage batteries used in large quantities at present, mainly including Ni plate of positive electrode material, Cd plate of negative electrode material and NaOH solution of electrolyte. The existing nickel-cadmium alkaline storage battery has the disadvantage of slow charging speed because of the small potential difference between the positive and negative electrode materials; element, so that the nickel-cadmium alkaline storage battery has the disadvantage of not being environmentally friendly. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of slow charging speed and serious environmental pollution existing in the alkaline storage battery in the prior art, and provide an alkaline storage battery with a faster c...
