Embodiment Construction

[0033] The content of the present invention will be described below in conjunction with specific embodiments.

[0034] like figure 1 Shown is the SEM characterization diagram after formation of the negative plate of the start-stop battery according to the present invention. The negative plate of the start-stop battery of the present invention adopts a graphene formula, and graphene has a monoatomic layer structure with good toughness, and its specific surface area can reach 2600m 2 Above / g, its excellent characteristics determine that it can form an effective "surface-to-surface" contact mode with the electrode active material particles. In addition, graphene has excellent electrical conductivity, and is currently the world's smallest known resistivity. material, the resistivity of single-layer graphene is 0.01×10 -6 mΩ, so adding graphene to the electrode material can effectively improve the conductivity of the electrode, thereby increasing the utilization rate of the acti...

Abstract

The invention discloses a high-performance AGM start-stop battery based on a graphene functional material. The preparation method of the negative plate of the start-stop battery includes the followingsteps: S1, preparing graphene slurry; S2, preparing negative lead paste; and S3, and forming a plate by coating. The preparation method of the grid of the start-stop battery includes the following steps: S1, preparing graphene-based alloy; S2, making a lead strip; and S3, forming a grid by stamping. According to the high-performance AGM start-stop battery based on a graphene functional material in the invention, the negative plate and the positive grid are made of graphene. Graphene is of a monoatomic layer structure, and effective 'face-to-face' contact is formed between graphene and the active material particles of the electrodes, so that the conductivity of the electrodes is improved. Therefore, the utilization rate of active materials is increased, and the cycle life of the battery isprolonged.

Description

technical field [0001] The invention relates to an automobile AGM start-stop battery, especially a high-performance AGM start-stop battery based on graphene functional materials, including the pole plate, grid and high-strength AGM separator of the start-stop battery, etc., belonging to Automotive battery technology field. Background technique [0002] With the increasingly stringent national requirements on automobile exhaust emissions, automobile OEMs require the development of a start-stop system with micro-mixing function. Satisfied that the car can start or stop quickly when encountering traffic lights, and the starting frequency is 3-6 times higher than that of the previous engine. Existing batteries cannot meet the actual use requirements of OEMs. Contents of the invention [0003] The present invention aims at the deficiencies in the prior art, and proposes a high-performance AGM start-stop battery based on graphene functional materials. The purpose of the prese...
