Recently, Guangzhou Automobile Group said on the interactive platform of Shanghai Stock Exchange that the research and development of graphene battery is continuing. It is expected that this technology will be put into mass production testing by the end of this year, and whether it can be mass-produced still needs to wait for the verification results of real vehicles. Relevant information will be released according to the progress of the project.
Guangzhou Automobile Group said that the specific principle of graphene battery research and development is to add graphene with three-dimensional structure as an additive to the anode and cathode of the battery to improve the charging performance of the battery. At present, the company's related graphene technology has been patented, covering graphene preparation, supercapacitors, fast charging batteries and other technical fields.
It is understood that GAC's graphene technology was announced at GAC Science and Technology Day in July this year. According to the official, based on the excellent conductivity and special three-dimensional structure of graphene, a super-fast rechargeable battery has been developed, which can fully charge 80% of the electricity in 8 minutes, realize charging 10 minute, and last for 200-300 kilometers, with charging speed comparable to refueling.
At present, GAC has preliminarily verified graphene technology from multiple levels of battery, module and vehicle.
Graphene materials are mainly used in many fields, such as fast-charging lithium-ion batteries, supercapacitors, lithium-sulfur batteries, lightweight body materials and so on. However, high cost has always been an obstacle to large-scale production and application.
On 20 14, Guangzhou Automobile Group responded to the call of national policy and started the research and development of graphene technology. After six years of exploration, we have gradually mastered the preparation and application technology of three-dimensional graphene (3DG) with independent intellectual property rights. 20 19, 1 1, the "super rechargeable battery" based on 3D graphene (3DG) material independently developed by GAC was officially announced. At the end of this year, the research and development of graphene battery mass production has finally moved from the laboratory to the real vehicle, and the Guangzhou Automobile Aian model will be equipped with relevant technical achievements.
165438+1On October 20th, at the press conference of Guangzhou Automobile Group in 2020, Feng Xingya, general manager of Guangzhou Automobile Group, announced that the "Guangzhou Automobile Aian" brand would operate independently and build a high-end technology brand in an all-round way. Subsequently, Gu Huinan, general manager of GAC Aian, officially announced that the company was renamed as "GAC Aian New Energy Automobile Co., Ltd." and "GAC Aian" would be positioned as a high-end intelligent electric vehicle brand.
Guangzhou Automobile Aian 1 1 sold 7,200 vehicles, up 20% year-on-year; From 1 to 1 1, the cumulative sales volume reached 53,000 units, a year-on-year increase of 62%.
