High-heat-dissipation graphene lithium power battery

Abstract

The invention discloses a high-heat-dissipation graphene lithium power battery comprising a slide rail. A first fixing plate and a second fixing plate are respectively fixedly mounted on the left andright sides of the top of the slide rail. The top of the slide rail is slidably connected with the left and right sides of the bottom of the battery body through slide blocks. The high-heat-dissipation graphene lithium power battery has a simple structure, convenient operation and low cost, and the heat dissipated by the battery body is rapidly absorbed by the evaporation tube section so that thehot air is cooled into water droplets by the adiabatic pipe section and the condensing pipe section, the cooling efficiency can be improved, then the high-heat-dissipation graphene lithium power battery can rapidly dissipate heat during charging, the high-heat-dissipation graphene lithium power battery can be assisted to reduce the heat of production in time, the purpose of reducing the energy loss can be achieved and finally waste of a large amount of energy can be avoided. Meanwhile, the damage of the heat to the battery can be reduced and the service life of the battery can be improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a graphene lithium power battery with high heat dissipation. Background technique [0002] Graphene is the thinnest known material, only one carbon atom thick, and it is also the thermal conductor with the best thermal conductivity. [0003] The theoretical battery weight of this material is half that of traditional lithium-ion batteries, the thickness will be greatly reduced, and the storage capacity is several times higher. According to the estimates of researchers at Rensselaer Polytechnic Institute in the United States, graphene anode materials are more expensive than those commonly used in lithium-ion batteries. The charging and discharging speed of graphite anode is 10 times faster. According to reports, if used in electric vehicles, one charge can be completed in 8 minutes, and the driving range can reach 1000 kilometers. [0004] Graphene has been listed as an importan...

AI Technical Summary

Problems solved by technology

After testing, the attenuation rate of graphene battery is within 15% after 2000 times of charging and discharging, which is about 40~80% compared with that of ordinary lithium battery. It can be fully charged in half an hour with a charging speed of 5000 mAh. If the circuit design is appropriate, it can theoretically be within 5 seconds. It is fully charged, but high-speed charging causes a lot of battery energy to be wasted, and a large amount of heat causes great damage to the battery, seriously affecting the service life of the battery
