　　Innovation of power battery drying process under high nickel system

　　When power battery companies introduce high-energy-density materials, drying equipment companies should provide customers with more consistent and faster drying products starting from the material end, and then to the cell drying before liquid injection to form a high degree of cooperation.

The large-scale market application of high-nickel system power batteries is entering the countdown. From the perspective of car companies, the BMW X1 (parameter|picture) PHEV equipped with Ningde era 811 battery system has been launched, and many models that are about to be mass-produced, including Geely Geometry A, Weilai ES6, GAC New Energy AiON.S, etc. Announced supporting high-nickel batteries. From the perspective of power battery companies, in addition to CATL, the second-tier companies are also accelerating product development, manufacturing, and testing and verification of high-nickel systems. In this context, due to the extremely stringent requirements for moisture and environment in the production and manufacture of high-nickel system power batteries, higher requirements are also put forward for the core drying process. At the 12th High-tech Lithium Battery Industry Summit Forum to be held on June 21, Long Guobin, Manager of Leiyu Technology R&D and Manufacturing Center, will give a keynote speech entitled "Innovation of Drying Process for Power Batteries under High Nickel System". When power battery companies introduce high-energy-density materials, drying equipment companies should provide customers with more consistent and faster drying products starting from the material end, and then to the cell drying before liquid injection to form a high degree of cooperation. In terms of materials, from the previous NCM523 to NCM811, with the higher energy density of ternary materials, Radium Technology began to carry out related research and development and layout for the drying of materials. At present, the powder drying automation system launched by Leiyu Technology to the market has the functions of automatic shaking and weighing, continuous feeding and discharging, and realizes unmanned production; powder contact heating, high temperature consistency, making powder powder in each area The body is evenly heated and fully dried; low energy consumption, which can be reduced by 50%-60% under the same production capacity; high maintainability, which can realize quick changeover production. In terms of cell drying, in order to solve the problem of drying consistency, Leiyu Technology has launched an open-roll drying product - pole piece bakingrolltoRoll high vacuum pole roll drying system. It is reported that the main features of this product are: the drying speed can reach 120m/min, and the width is 900mm; there is no risk of broken belt, no pole ear wrinkling, and complete isolation of harmful substances; sufficient vacuum drying, good drying effect, high production capacity, low energy consumption, The energy consumption is lower than 8 times of the relative production capacity; the compatibility is stronger, the drying consistency is 99.99%, and the drying effect is far superior to the current drying equipment; the stress of the pole roll is effectively released; it will not cause powder removal and the toughness of the pole piece is reduced. The contact drying technology has matured day by day, with prominent advantages, and has been accepted by battery manufacturers. Facing the innovation of high-capacity materials such as high-nickel, conventional drying technologies such as ordinary air transport type and ordinary tunnel type can basically not meet the requirements. Powder drying-electrode drying-cell drying needs to use contact drying technology. drying technique. Because technology is always innovating, the upstream and downstream of the supply chain should maintain close communication, continuous sharing, and continuous investment in research and development.
