Lithium titanate battery current collector and preparation method and application thereof

The invention discloses a lithium titanate battery current collector. The lithium titanate battery current collector includes an aluminum foil substrate. At least one surface of the aluminum foil substrate is coated with a titanium carbide layer. The current collector of the invention is used to prepared positive and negative electrode sheets to effectively improve the conductivity of a lithium titanate material and strengthen the peeling force of the battery electrode sheets. According to the invention, a gravure printing method is used for coating, and so the uniformity of the coating layerin the current collector is effectively improve. The current collector of the invention is applied to a lithium ion battery so as to effectively reduce internal resistance of a lithium titanate battery and improve the cycle performance of the lithium titanate battery. 本发明公开了一种钛酸锂电池集流体，其包括铝箔基体，在所述铝箔基体的至少一个表面上涂覆碳化钛层。通过采用本发明集流体制备正、负极片，有效的提高了钛酸锂材料的导电性，加强了电池极片的剥离力；本发明通过采用凹版印刷的方法进行涂覆，有效的提高了集流体中涂覆层的均匀性；通过将本发明集流体应用于锂离子电池中，有效的减小钛酸
