Abstract
Description
technical field
[0001] The invention relates to a lithium titanate battery, and in particular provides a hydrothermal method for increasing the capacity of a lithium titanate single battery. Background technique
[0002] In the 1990s, lithium titanate Li 4 Ti 5 o 12 Appearing as the anode material of a new type of lithium battery, it has been valued due to its high safety, high stability, long life and green environmental protection. As far as the currently used lithium titanate battery is concerned, lithium titanate is used as the negative electrode material instead of graphite, and it can be combined with lithium manganate, ternary materials or lithium iron phosphate and other positive electrode materials to form a 2.4V or 1.9V lithium ion secondary battery. Lithium titanate battery has obvious advantages, but its shortcomings are also obvious, such as relatively low energy density and weak battery life, which is largely determined by the voltage of the single battery. ...
