Embodiment Construction

[0045] The invention discloses a mixed glass fiber accumulator diaphragm and a method for manufacturing the diaphragm. The constituent components of the mixed glass fiber accumulator diaphragm include superfine glass fiber cotton, hydrophobic fiber material and gas phase silicon dioxide. When manufacturing the diaphragm, the discharge capacity of the battery is improved by adding hydrophobic fiber substances to the hydrophilic glass fiber, and the tensile strength and liquid absorption of the diaphragm are enhanced, thereby improving the cycle life of the battery. By adding an appropriate amount of fumed silicon dioxide, the puncture resistance and tensile strength of the separator in dry and wet states are increased, and the production efficiency and performance of the battery are improved at the same time.

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of...

Abstract

The invention discloses a hybrid glass fiber diaphragm for a storage battery as well as a method and system for manufacturing the hybrid glass fiber diaphragm. The hybrid glass fiber diaphragm for the storage battery mainly comprises superfine glass fiber cotton, a hydrophobic fiber substance and aerosol, wherein according to the hybrid glass fiber diaphragm, the hydrophobic fiber substance is added in a hydrophilic glass fiber, so that the discharge capacity of the storage battery is increased, the tensile strength of the diaphragm is enhanced, the electrolyte absorbing quantity of the diaphragm is increased and further the cycle service life of the storage battery is prolonged; and due to the addition of a proper amount of aerosol, the pierce resisting strength and the tensile strength of the diaphragm in a dry state and a wet state are enhanced. Therefore, the performances of the diaphragm are improved; and meanwhile, the production efficiency and performances of the battery are improved.

Description

technical field [0001] The invention relates to the field of accumulator manufacturing, in particular to a hybrid glass fiber accumulator diaphragm, a diaphragm manufacturing method and a system. Background technique [0002] At present, ultra-fine glass fiber diaphragms are widely used in lead-acid batteries in China and are an important part of batteries. Such as figure 1 Shown is a structural diagram of the battery electrode group, including a pole plate 11 and a diaphragm 12, wherein the pole plate 11 includes a positive pole plate and a negative pole plate, and the positive pole plate and the negative pole plate are arranged at intervals in the structure, and the diaphragm 12 separates them. [0003] The material of the diaphragm itself is an electronic insulator, which is resistant to chemical and electrochemical corrosion. Its main function is to prevent the short circuit of the positive and negative electrodes, but it cannot significantly increase the internal resis...
