Abstract

The invention discloses a lead acid storage battery electrode. The lead acid storage battery electrode comprises a current collector and an active substance, wherein the electrode is provided with at least one stable void which is not filled with the active substance and runs through or does not run through the interior of the electrode, the size of the stable void in a direction perpendicular to the surface of the electrode and penetrating into the electrode is greater than one tenths of the thickness of a flat electrode, a winded electrode and a bipolar electrode, or greater than one tenths of a radial length of a tubular electrode and a columnar electrode, the total area of the stable void contacting the surface of the active substance is greater than the total area of the stable void not contacting the surface of the active substance, and a minimum appearance size of the stable void is greater than an average aperture of the porous active substance of the electrode. The invention also discloses a lead acid storage battery comprising the electrode, and a manufacturing method, component and device of the electrode. By adopting the lead acid storage battery electrode, the performances of the lead acid storage battery electrode and the battery such as the specific surface area, specific energy and the like are remarkably improved.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to an electrode of a lead-acid battery and related manufacturing methods, components and equipment. Background technique [0002] According to different electrode structures, lead-acid batteries generally include flat lead-acid batteries, tubular lead-acid batteries, wound lead-acid batteries, bipolar lead-acid batteries, horizontal lead-cloth lead-acid batteries, and foam grid lead-acid batteries. Acid batteries, formed lead-acid batteries, and column electrode lead-acid batteries, etc. Among them, flat-plate, tubular, and wound lead-acid batteries are currently the most widely used. Lead-acid batteries have many advantages: cheap and easy to obtain, high performance / price ratio, safe and stable, and recyclable. However, lead-acid batteries also have obvious shortcomings. One of them is that its battery specific energy is low. Living activities are increasingly developed and improved today, ...
