Problems solved by technology

However, in the traditional lead-acid batteries currently on the market, the plates are mostly made of lead, mercury, and cadmium alloys. During the process, the specific energy is low, the self-discharge of the battery is large, the capacity of the low-temperature environment drops sharply, the water loss is serious, and there is a possibility of hydrogen evolution flash explosion at the same time, and the safety performance is poor.
At the same time, in order to prevent the vulcanization of battery plates, frequent maintenance is required, which will lead to acid corrosion and acid mist pollution, and mercury and cadmium poisonous pollution produced after vulcanization of plates can cause irreversible damage to personnel and the environment. It is not easy to recycle, and the lead sulfate in it will cause great pollution and damage to the soil and water environment

Description

technical field [0001] The invention relates to a storage battery, in particular to a novel silicate electrolyte storage battery. Background technique [0002] Since the advent of lead-acid batteries, they have been widely used due to their high electromotive force, small internal resistance, reliable performance and low price. However, in the traditional lead-acid batteries currently on the market, the plates are mostly made of lead, mercury, and cadmium alloys. During the process, the specific energy is low, the self-discharge of the battery is large, the capacity of the low-temperature environment drops sharply, the water loss is serious, and at the same time, there may be a flash explosion of hydrogen evolution, and the safety performance is poor. At the same time, in order to prevent the vulcanization of battery plates, frequent maintenance is required, which will lead to acid corrosion and acid mist pollution, and mercury and cadmium poisonous pollution produced after...
