Abstract

The invention relates to a high-energy-density bag cadmium-nickel alkali accumulator with a new compound negative and positive electrode, which is made up of a positive electrode board, a negative electrode board, an isolating material, a battery capacitance and auxiliary parts, and electrolyte. The character is: the positive electrode is a bag type positive electrode board; the negative electrode board is a pulling dried negative board. The invention can maintain the merits of traditional bag cadmium-nickel alkali accumulator, and it can upgrades the energy-density of the accumulator, and it won't increase the manufacturing cost of the accumulator; the accumulator made up with the invention with the same volume, capacity and magnification, the liquid maintaining period of the accumulator is fives times to the traditional accumulator.

Description

technical field [0001] The invention belongs to a cadmium-nickel alkaline storage battery and relates to a high specific energy cadmium-nickel alkaline storage battery with a novel combination of positive and negative electrodes. This kind of battery not only has the characteristics and advantages of the traditional bag-type nickel-cadmium alkaline battery, but also has its own unique advantages, such as greatly improving the specific energy of the bag-type nickel-cadmium alkaline battery. Background technique [0002] The bag-type nickel-cadmium alkaline storage battery is a very important series of nickel-cadmium alkaline storage battery, which not only has a large output, but also has a wide range of applications. In addition to the electrolyte, the traditional bag-type cadmium-nickel alkaline battery generally has the following structures: (1) the positive and negative plates are the powdery positive and negative active materials wrapped in a flat perforated steel strip,...
