Battery 3D printing -SEL technology introduction

￮ SEL slurry extrusion lamination technology is a subversive electrode preparation process, through the precision print nozzle uniform extrusion of battery anode and cathode or electrolyte materials, with micron-level high-precision motion control system to achieve precision molding of electrode structure. SEL process is widely applicable to a variety of battery material systems, and can realize the preparation of positive and negative battery electrodes with unique structural design, as well as ultra-thin, stepped all-solid-state battery electrolyte layer, and can efficiently complete the preparation of all-solid-state batteries and other small energy storage devices.

￮ As an innovative process scheme, SEL slurry extrusion stacking technology not only provides a new idea for advanced battery manufacturing, but also provides an innovative technical means for battery preparation in different application scenarios, and opens a new possibility for customized battery manufacturing.

Technological advantage

￮ High precision, high design freedom: can manufacture micro batteries, can manufacture complex structure batteries such as ring batteries, shape batteries, etc.

￮ High energy density: Continuous microporous thick electrodes reduce the use of fluid collectors and diaphragms, increasing the battery energy density.

￮ High power density: 3D continuous microchannel electrodes can provide a wider ion diffusion channel to improve battery power density.

￮ Low cost, low energy consumption: Thick electrodes can reduce the use of fluid collection and diaphragm, dry method can reduce solvent consumption.

￮ Multi-material, multi-application: 3D printing process can adapt to a variety of battery materials, and can manufacture multiple types of new batteries. Such as flexible batteries, solid state lithium-ion batteries, wearable batteries, implantable medical batteries, fuel cells, perovskite thin film batteries and so on.

￮ Manufacturing structural batteries: Allows the design of the battery to fit the product, making the battery part of the product structure.
