Silicon glass spacing plate for accumulator as well as preparing technique thereof

Abstract

The invention discloses a silicon glass clapboard for a accumulator and preparation technique thereof. Weight ratios of the silicon glass clapboard are: 60-90 parts of micro-fiber glass wool; 20-50 parts of mixture of silicon dioxide particles and nano-stage gas-phase silicon dioxide; 1-10 parts of adhesive; and 1-10 parts of polymers and deposition resisting agent. The preparation technique includes: pulping raw material(the micro-fiber glass wool) by adding water and sulfuric acid; preparing pulp by adding the mixture of the silicon dioxide particles and the nano-stage gas-phase silicon dioxide, and the adhesive; coacervation(adding the polymers and the deposition resisting agent); removing slag; fetch the clapboard; drying; coiling; cutting; and packaging. The silicon glass clapboard is adapted for accumulator, in particular for energy-stored battery used for automobile, ship, train, electric motorcycle, wind energy, solar energy and electric network adjustment, and UPS power supply battery.

Description

technical field [0001] The invention relates to a novel electrolyte carrier, in particular to a silicon glass separator for storage battery and its manufacturing process. Background technique [0002] Fiber separators are an important part of sealed lead-acid batteries. Glass fiber separators have the advantages of strong acid resistance, high porosity, small pore size, high liquid absorption rate, and low resistance. The disadvantages are small specific surface area and apparent density. Small, such separators are expensive to manufacture, and the assembly of the battery also puts pressure on the pole group, which inevitably increases the cost of battery manufacturing. Assembling batteries with silicon glass separators is the key to improving the quality of batteries. Adding silicon powder to glass fiber separators can greatly improve the efficiency and service life of batteries. An unresolved problem that has been pursued. How to combine the two advantages of advanced gl...
