Abstract

The invention provides a large-capacity graphene battery capable of rapidly charging, and relates to the technical field of batteries. The large-capacity graphene battery capable of rapidly charging,fabricated by the invention, comprises a positive pole plate, a negative pole plate, a separator, an electrolyte and a battery shell, the phenomena of small storage capacity and slow charging speed ofan existing graphene battery are solved, meanwhile, the corrosion resistance of the battery is improved, the service lifetime is prolonged, the large-capacity graphene battery is relatively good in stability, and no harm to a human body and an environment is generated; and compared with a traditional market graphene battery, it is verified that the charging time is obviously shortened by 34.94% under the same charging condition, and the charge-discharge efficiency of the battery can reach 87.73%.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular, to a large-capacity fast-charging graphene battery. Background technique [0002] Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional honeycomb lattice, and is the basic building block of graphite materials in all other dimensions, which has the thinnest, largest specific surface area, hardest, most tensile, etc. Many unique properties such as the strongest properties in history, high-performance sensor functions, and catalyst-like functions. The emergence of graphene is expected to trigger a material revolution in many fields such as structural materials and functional materials for electronic devices. Due to its many special properties, many scholars call graphene "the material that will change the 21st century" and predict that "the 21st century will be the era of carbon (C)". Compared with existing materials, graphene has many "best in history...
