Abstract

The invention discloses a high-capacity lithium titanate battery comprising a casing and a replacement casing. The replacement casing is fixedly connected to one side of the casing, the casing is internally provided with a first positive plate, and the replacement casing is internally provided with a second positive plate. A positive joint and a negative joint are symmetrically mounted at the upper end of the casing, the positive joint is in contact with a chute, the negative joint is connected with a negative plate disposed in the casing, the upper ends of the casing and the replacement casing are provided with an inner rail, the inner rail is sleeved with an outer rail, a sealing groove is arranged between the inner rail and the inner walls of the casing and the replacement casing, and the outer rail is disposed in the sealing groove. By adopting the two positive plates which can be alternated, the battery can avoid loss of the plates caused by repeated charge and discharge, and theuse capacity of the battery can be improved by using the different plates in the charge and discharge process, and the battery life is prolonged by combining a common lithium battery with the titanatebattery.

Description

Technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a high-capacity lithium titanate battery and a method of use thereof. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. Lithium ion battery does not contain metallic lithium and can be charged and discharged repeatedly. It is a commonly used battery in modern society. Among them, titanic acid Lithium battery capacity has the characteristics of good safety, long cycle life, and good rate. Lithium titanate battery is a kind of anode material for lithium ion battery-lithium titanate, which can be combined with lithium manganate, ternary material or lithium iron phosphate And other positive electrode materials form a 2.4V or 1.9V lithium ion secondary battery. [0003] The general lithium battery adopts a fixed structure, in which both the positive e...
