Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a lithium battery and a battery case thereof. The battery case comprises an inner case and an outer case which are concentrically arranged, two cover plates and two electrodeassemblies. The inner case is accommodated in the outer case, the two cover plates are in sealed connection with edges of openings at two ends of the outer case to seal the openings at the two ends ofthe outer case, and the inner case is clamped between the two cover plates. A cell of the lithium battery adopts an annular structure and sleeves the inner case, and when the lithium battery works, the heat in the hollow cell can be significantly reduced. Besides, the inner case is contacted with the inside of the cell, so that a heat conducting role can be played. Therefore, heat produced duringworking of the cell can be quickly conducted to the cover plates at two ends through the inner case and further emitted. The lithium battery can reduce heat in the cell on one hand and accelerate emission of heat in the cell on the other hand. Thus, the heat dissipation of the lithium battery and the battery case thereof is effectively improved.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a lithium battery and a battery casing thereof. Background technique [0002] Lithium batteries are widely used in work and life. Lithium batteries have better power storage and discharge performance and are welcomed by most people. With the rapid development of lithium battery technology and the increasing requirements for lithium batteries in new energy applications such as electric vehicles, the capacity and power of lithium batteries are also increasing. [0003] With the increase of battery capacity and power, the calorific value of the lithium battery in the working state also increases. If the heat is not dissipated in time, it will cause the internal temperature of the battery to rise, and eventually lead to deformation of the battery, affect the quality of battery charging and discharging, and even cause an explosion. [0004] However, common lithium b...
