Problems solved by technology

In order to improve the safety of lithium batteries, explosion-proof wires are usually installed on the casing. When the internal pressure of the lithium battery is too high, the explosion-proof wires rupture to release gas and prevent the danger of lithium battery explosion. The application of such explosion-proof wires will cause the casing to If the bo

Abstract

The present invention discloses an efficient lithium battery, which comprises a housing, a positive electrode, a negative electrode and a pressure limitation plate, wherein the pressure limitation plate is arranged on the middle-upper portion inside the housing, the positive electrode and the negative electrode are sequentially arranged below the pressure limitation plate from top to bottom, and are sponge-like porous electrodes, and the housing above the pressure limitation plate is provided with a gas exhaust hole. The technical problem solved by the present invention is to improve the safety of the lithium battery. According to the efficient lithium battery, the pressure limitation plate provided for pressure limitation breaking and arranged inside the housing and the sponge-like porous electrodes are arranged, such that the pressure limitation plate is self-damaged and releases gas when the inner pressure is too high so as to ensure the safety of the lithium battery, effectively avoid breaking of the lithium battery housing, and prevent liquid leakage and generation of corrosion, environmental pollution and other incidents; and the specific surface area of the electrode is improved with the arranged porous electrodes so as to effectively improve the capacity of the battery.

Description

[0001] technical field [0002] The invention relates to a battery, in particular to a high-efficiency lithium battery. Background technique [0003] Lithium battery refers to a battery containing lithium (including metal lithium, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries usually come in two shapes: cylindrical and square. The inside of the battery adopts a spiral wound structure, and a very fine and highly permeable polyethylene film separator material is used to space the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganese oxide, lithium ...
