Problems solved by technology

Since the colloidal electrolyte is in direct contact with the plate, it may cover the pores of the active material on the plate, blocking the migration channel of the reactant, resulting in a decrease in electrode performance; With the prolongation of the infusion time, the viscosity continues to increase, gradually transforming into a solid state, and finally loses its fluidity completely, and the electrolyte cannot flow deep into the battery, resulting in uneven filling of the electrolyte and dissatisfaction. It cannot electrochemically react with all active substances, so that the battery capacity will decrease, generally lower than 20 ampere hours

Embodiment Construction

[0029] The present invention will be further described in conjunction with specific embodiments.

[0030] 1. To prepare liquid phase electrolyte, add 342ml concentrated sulfuric acid to 1000ml pure water to make a sulfuric acid solution with a density of 1.27-1.29.

[0031] 2. Prepare solid phase electrolyte in the form of thixotropic colloid,

[0032] (1) Prepare a sulfuric acid solution with a density of 1.54-1.59, and add 265ml of concentrated sulfuric acid to 235ml of pure water.

[0033] (2) Prepare the curing agent, take by weighing 120-400g of fumed silica with a particle size of 10-20nm, 1-20g of hydroxyethyl cellulose, and 250ml of pure water, all of which are poured into a stirrer and heated at 2000 rpm Stir at a speed of 1 / min, and then increase the speed to stir. After it is completely dissolved, add 250ml of pure water and stir evenly at high speed.

[0034] (3) To prepare the additive, first heat 5-12ml of pure water to 20-30°C, then add 6-12ml of glycerol, sti...

Abstract

This invention relates to a second battery with different electrolytes, which solves the problems of the solid storage battery with low capacity when entering the activity subject holes and capillary. The invention relates adopts abio-compound fiber material package electrode board as isolation board and filling the hydraulic electrolytes between the electrode and the isolation board. The invention overcomes the above shortcomings and has a battery with good quality and solid electrode board.

Description

technical field [0001] The invention relates to the field of methods and devices for the direct conversion of chemical energy into electrical energy, in particular secondary batteries containing two different electrolytes. Background technique [0002] In recent years, fully sealed maintenance-free batteries have appeared in the field of batteries, especially lead-acid batteries. The main improvement of this kind of fully sealed maintenance-free batteries is to change the liquid electrolyte to colloidal electrolyte, which not only improves the performance of the battery, but also greatly facilitates It has attracted users and has been rapidly promoted. The electrochemical reaction in the lead-acid battery shows that the smooth flow of the reaction path must be ensured to prevent blockage. For example, the oxygen produced by the positive electrode must reach the negative electrode smoothly and be absorbed by the negative electrode. Since the colloidal electrolyte is in direc...
