Problems solved by technology

However, the above-mentioned traditional physical methods cannot fundamentally solve the direct bonding fastness and dispersibility of the conductive medium and the colloid. Combined with the high price of the conductive glue, the conductive medium after gelling is easy to fall off from the surface of the colloid, or form a phenomenon of partial agglomeration , or silver migration will occur under DC electric field and moisture conditions, which will affect the conductivity of the finished material

Description

technical field [0001] The invention relates to the technical field of conductive glue, in particular to a low-temperature power battery based on conductive glue, a preparation method and application of the conductive glue. Background technique [0002] With the development of science and technology, electric vehicles are becoming more and more popular, and the state also has various preferential policies for this. As the core key component of electric vehicles, batteries have a decisive impact on the driving performance of electric vehicles. The traditional lithium battery has poor temperature adaptability, and there is no overcharge protection device, and its structure and function are relatively simple. [0003] In order to ensure the performance and safety of power batteries, on June 17, 2009, the Ministry of Industry and Information Technology issued the "New Energy Vehicle Manufacturers and Product Access Management Rules" (Industrial Industry [2009] No. 44) in July 2...
