Protection device for safe use of lithium battery

Abstract

The utility model relates to the technical field of lithium battery discloses protection device of safe use of lithium battery, including shell, the inside of shell has the inner chamber of accommodating lithium battery and the guide channel of guiding lithium battery energy (heat and the energy such as gas / flame produced along with) orderly release, and the inner end of guide channel communicates with the inner chamber, and the outer end of guide channel penetrates the outer periphery of shell, forms the guide opening, when lithium battery breaks down or is destroyed, energy can be orderly released from the inner chamber to the outside of shell through the guide channel, thereby avoided the disorderly eruption of energy, effectively solved the problem of the uncontrollable fire and personnel casualty accident caused by the disorderly energy release of lithium battery.

Claims

1. A protective device for the safe use of lithium batteries, characterized in that, The device includes a housing, the interior of which has an inner cavity for accommodating a lithium battery and a guide channel for guiding the orderly release of energy from the lithium battery. The inner end of the guide channel is connected to the inner cavity, and the outer end of the guide channel penetrates the outer periphery of the housing to form a guide opening.

2. The protection device for the safe use of lithium batteries as described in claim 1, characterized in that, The housing has one or more guide channels, and the outer periphery of the housing has one or more guide openings.

3. The protection device for the safe use of lithium batteries as described in claim 1, characterized in that, The guide openings are arranged in a flat strip shape.

4. The protection device for the safe use of lithium batteries as described in claim 1, characterized in that, The outer casing has a wrapping portion in the middle that surrounds and wraps around the periphery of the lithium battery. The wrapping portion encloses and forms the inner cavity. One end of the inner cavity is open to form an end opening. Each end of the outer shell has a guide portion, which encloses to form a guide channel. The inner end of the guide portion is connected to the end of the wrapping portion. The inner end of the guide channel is connected to the inner cavity through an end opening. The outer end of the guide portion encloses to form the guide opening.

5. The protection device for the safe use of lithium batteries as described in claim 1, characterized in that, The guide opening extends outward to form a guide tube section, which has a cavity through which the lithium battery releases energy in an orderly manner, and the cavity is connected to the guide channel.

6. The protection device for the safe use of lithium batteries as described in any one of claims 1-5, characterized in that, The outer shell includes an inner layer and an outer layer wrapped around the inner layer. The inner layer is made of silicon carbide composite material, and the outer layer is made of carbon fiber material.
