Abstract
The present invention provides a positive pole active substance composition of a closed lead-acid accumulator. The composition is characterized in that the present invention has favorable charge and discharge characteristics and the performance of preventing softening and falling, the electrochemical capacity of positive slab lattice is enlarged, and the service life of charge and discharge cycles is prolonged.
Description
Technical field: well-known, closed lead acid accumulator has become the important component part of international secondary cell, its market demand increases day by day, because the continuous expansion of application, battery quality is required to improve constantly, require closed lead acid accumulator to have higher performance, and one of performance methodology that improves closed lead acid accumulator is the novel battery positive electrode active material composition of development.This invention belongs to field of new.
Background technology: the disadvantage that closed lead acid accumulator and other secondary cell such as nickel-hydride battery, lithium ion battery are compared is that specific energy is low, improves the specific energy of closed lead acid accumulator for this reason, is the important topic of closed lead acid accumulator research always.The most direct way that improves the closed lead acid accumulator specific energy is to improve the discharge capacity of closed lead acid accumulator, the discharge capacity of closed lead acid accumulator is controlled by positive electrode active compound composition, and the positive electrode active compound composition of for this reason developing high power capacity has significant meaning.
Summary of the invention: the positive pole active matter composition of closed lead acid accumulator of anti-softening and shedding that the purpose of this invention is to provide a kind of high power capacity improves the specific energy of closed lead acid accumulator to improve the electrochemistry capacitance of closed lead acid accumulator.The object of the present invention is achieved like this, and its characteristic is that the composition of this positive active material is: 100kgPb powder+concentration is 63wt%H
