Abstract
The invention discloses a nano-silicon colloid electrolyte which, except for sulphuric acid electrolyte, comprises some other chemical constituents like phosphoric acid, sodium silicate, sodium sulfate, ethanol, deionized water and so on. The involvement of catalysts improves the velocity of ion migration so that a high-performance nano-silicon colloid electrolyte can be achieved, the inner resistance is reduced, and the capacity is enhanced. The sodium silicate used in the invention is processed by specific techniques, the particle size of silicon dioxide is controlled between 1 nm to 100 nm, the gelling time of the colloid can be manually controlled, avoiding the drawback that the properties thereof are difficult to be developed due to the perfusion after gelling. The inclusiveness of the colloid resolves the persistent ailment that electrolyte stratification negatively influences service life of storage batteries, prolongs thereby cycle life of storage batteries, and enhances the performance in resistance to low temperature.
Description
Technical field
The present invention relates to a kind of power lead acid battery that is used for, be particularly useful for a kind of manufacture of colloidal electrolyte technology of AGM dividing plate storage battery assembling.
Background technology
In recent years, the valve controlled sealed lead-acid accumulator technical development is rapid, and it is widely used in emergency power supply, UPS, solar energy storage battery, wind power generation energy-storage battery, mine lamp, electric tool, Moped Scooter etc..Especially Moped Scooter series of products, want that cube is little, capacity is big, the charging interval is short, discharge time is long, the depth of discharge that circulates deeply will reach 70%～100%, discharge time 〉=350 time, foolproof by bike, the unordered formula of charging of people, power of motor increase this three-in-one of formula in addition, battery industry is had higher requirement, the generation of colloid storage battery technology makes the realization of above requirement become possibility.
But existing colloid storage battery technology, no matter be to adopt sodium metasilicate or aerosil to do raw material (colloid solidification agent), have all that internal resistance is big, capacity is low, discharge performance decline, thermal runaway, the distortion of battery charge bulging, blast, cycle life has only about 300 times phenomenons such as (standard 〉=350 time), existing colloidal electrolyte can not satisfy the requirement of Moped Scooter storage battery, also is not suitable for using on the storage battery of AGM dividing plate assembling.
Summary of the invention
The purpose of this invention is to provide a kind of nano silica gel body electrolyte, it is fit to use the AGM dividing plate to assemble valve-regulated sealed colloid storage battery, and the problem that existing colloid storage battery is existed obtains the solution of essence.
