Abstract

The invention discloses a high-capacity lithium titanate battery, which comprises a casing and a replacement casing, the replacement casing is fixedly connected to one side of the casing, a first positive plate is arranged in the casing, and a second positive plate is arranged in the replacement casing. Two positive plates, the upper end of the housing is symmetrically equipped with a positive joint and a negative joint, the positive joint is in contact with the chute, the negative joint is connected with a negative plate, the negative plate is arranged in the shell, and the shell and the replacement The upper end of the shell is provided with an inner track, and an outer track is sleeved on the inner track, and a sealing groove is arranged between the inner track and the inner wall of the outer shell and the replacement shell, and the outer track is arranged in the sealing groove. The present invention can avoid the problem of loss of the plates due to repeated charge and discharge through the two positive plates that can be alternated, and the use of different plates in the charging and discharging process can increase the service capacity of the battery. The battery is combined with a lithium titanate battery to improve battery life.

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 for using the same. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Lithium ion battery does not contain metallic lithium and can be repeatedly charged and discharged. 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 performance. Lithium titanate battery is a negative electrode material for lithium ion batteries-lithium titanate, which can be used 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. [0003] The general lithium battery adopts a fixed struc...
