  1. Industry status, market demand and application scenarios<\/li><\/ol>

    During the battery preparation process, the conductivity of the positive and negative electrodes has a great influence on the final battery performance. The current common method is to add a certain proportion of conductive agent to the formula of the positive and negative electrodes to improve the power, capacity and other performance of the battery. However, the conductive agent itself cannot produce capacity. If the proportion is too large, the energy density of the battery will be reduced. This project uses an electric pulse method to process the powder particles, so that the effective contact area between the powders is increased and the conductivity between the particles is improved. In this way, the conductivity of the pole piece is improved without adding additional conductive agents.<\/p>

    1. Potential market size;<\/li><\/ol>

      Almost all automotive battery companies and power tool battery companies can apply this technology to improve the quality of batteries. Based on the annual shipment of 500 devices and the price of each device of 100,000 yuan, the annual output value is about 50 million.<\/p>

      1. Core competitiveness<\/li><\/ol>

        This patent adopts a new method to improve the power performance of the battery. Compared with the traditional method, there is no need to add additional conductive agents, reduce the battery energy density, and improve the power performance of the battery at the same time.<\/p>

        1. Potential benefits of application<\/li><\/ol>

          After adopting the method of this patent, the power performance of the battery is improved, the amount of conductive agent used can be appropriately reduced, and the energy density of the battery is increased. At the same time, after the power performance of the battery is improved, the temperature of the battery rises slowly during operation, which improves the safety performance of the battery and reduces the probability of fire and explosion.<\/p>

          1. Promotion of social value<\/li><\/ol>

            This project adopts a new method to improve the power performance of the battery, and can be organically combined with the existing battery production process. An electric pulse treatment process is added to the later stage of the battery coating process. The efficiency is synchronized with the coating, and it can achieve fully automatic processing. No additional labor is required, and the efficiency of the electrode production is not reduced. At the same time, the power performance and safety of the battery are improved, especially in the field of new energy vehicles, which has a high social value.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
