Abstract

The invention discloses a titanium-based titanium oxide plate and a manufacturing method thereof. The titanium-based titanium oxide plate comprises a titanium metal plate carrier and a titanium oxide film, wherein the titanium oxide film comprises main components of magneli phase (Ti4O7), titanium black (Ti5O9) and titanium oxide (Ti6O11), wherein the total content of Ti4O7, Ti5O9 and Ti6O11 is not less than 80 percent, and the content of the Ti4O7 is not less than 60 percent. The preparation of the titanium-based titanium oxide plate adopts a sol nano heat reduction technology, and the titanium oxide film is synthesized on situ at the high temperature on a titanium substrate by utilizing the reducibility of the titanium nano particles. The titanium-base titanium oxide plate has good conductivity, good corrosion resistance and good mechanical strength and can be used as an anode light grid of a high-energy lead storage battery, a polar plate of a bipolar battery and a collector body of other relevant chemical power supplies.

Description

technical field [0001] The invention relates to a titanium-based titanium suboxide plate and a manufacturing method thereof. The titanium-based titanium suboxide plate can be used as a current collector of a positive electrode light grid of a high-energy storage battery, a bipolar battery grid and other related chemical power sources. Background technique [0002] Titanium material has low density, high electrical conductivity, good machinability, and is very stable in sulfuric acid system. It is an ideal lightweight current collector for high-energy batteries. However, under acidic high potential conditions, the surface of titanium is easily oxidized to form a dense non-conductive oxide film. This "passivation" film will hinder the contact of electrons between the active material and the current collector, increasing the polarization. Deteriorate battery performance. In order to improve the surface conductivity and stability of the titanium plate, it is usually necessary t...
