New Courier: In the field of electric vehicles, the upgrade demand for battery thermal management is increasingly prominent. On March 19th, on the largest exhibition in the battery industry, DuPont brought the breakthrough solution to the battery pack fever management problem - Betatech™Polyurethane hot interface material. This material is used to bond the modules and cooling plates of the battery pack, which has excellent advantages of rapid glue, fast bonding, maintaining thermal conductivity, long operating time.
Car electricity tide is faster than expected. my country's auto industry association data shows that even in 2020 affected by new crown epidemics, my country's new energy automotive production and sales have completed 1366 million and 13.67 million, up 7.
5% and 10.9%, respectively. At the same time, to 2020, my country's accumulated sales reached 55.
577 million, and 5 million goals have exceeded. Looking forward to the future, according to the "New Energy Automotive Industry Development Plan (2021-12035)", until 2025, the sales volume of new energy vehicles will reach 20% of the total sales of automobile new cars; to 2035, electric transformation will be basically realized. The development space of new energy vehicles is extremely huge, but new energy vehicles are facing problems in safety in development, and the life is not enough to have high cost.
In order to help new energy vehicles develop faster and more steadily, the innovator in the field of materials science - DuPont brought a solution. DuPont cooperates with Nissan E.dams to speed up the automotive electrical innovation of the international automobile alliance (FIA), representing the development direction of the future automobile industry, and acting as an accelerating electric vehicle research and development.
DuPont has announced the establishment of technical partnerships in February 2021, and jointly explores the top electrical engineering design to accelerate the development of new automotive electrical technology, improve motor performance and battery safety. DuPont said that a key task in cooperation with Nissan E.dams is to use racing sports to test new technologies, and explore these technologies in future commercial electric vehicles.
DuPont cooperates with Alpinef1 to solve the mixing and pure electric car challenge to point out that cooperation with Nissan E.DAMS Electric Formula is a technical project that DuPont and Alpinef1 team (the original Renault F1 team). The cooperation between DuPont and Alpinef1 fleet is started in March 2019.
The engineers at the current two sides are working closely. In the harsh racing environment, the application of materials in the passenger car is solved in the development of mixing and pure electric vehicles. The most severe challenges, including battery and battery packaging, thermal management, power electronics, chassis light weight and durability, etc.
, thereby accelerating these solutions from racing tests to large-scale applications of road vehicles. Technical cooperation between the two sides has played a key use in the battery life, thermal management, security, durability, NVH performance, interconnection, and automotive structures, battery pack components, electric motors, and electronic components. DuPont New Products Betatech™Ultramoxide thermal interface material debut in CIBF2021 March 19-201, in the world's largest exhibition - the 14th my country International Battery Technology Exhibition / Exhibition (CIBF2021), DuPont as an adhesive and seal Technical market leadership brings breakthrough solutions to solve battery heat management problems - Betatech™Polyurethane thermal interface material.
As shown, Betatech™Excellent physical properties of polyurethane thermal interface materials: Betatech™The polyurethane thermal interface material maintains viscosity in a larger operating temperature range, which is essential to the integrity of the long-time maintenance material: Betatech™The polyurethane thermal interface material has a single component or a two-component product to be available, and is applied to the battery module and the liquid-cooled plate. Its ease of use has improved production efficiency and implements repeatable process operations in high yield assembly environments. The material advantage includes: formula: non-abrasive formulation, will not cause wear on equipment; glue: Flexible, can be compatible with two major processes; rapid bonding: The module is low in force; keep the thermal conductivity: It can realize good and no gap between the cell and the cooling plate, not a gap in the vertical aging test; operating time: reserved for 60 minutes; reliability: no physical changes during aging, vertical aging test Repairability: Repeated operation can be achieved due to small drawing force.
Betatech™Polyurethane thermal interface materials can also be hand-coated or automatically rubpting to achieve high yield production: It is reported that Betatech is preferred™Batch production test for several OEM electric vehicles currently is being carried out.
