Battery production with 3D printing coating technology

Discover how the TOPEM20 revolutionizes the production process of Solid-State Batteries with its advanced 3D printing coating technology. Learn about its key features and benefits, and how it enhances efficiency and precision in battery manufacturing.


TOPEM20 is a four-nozzles integrated battery 3D printing equipment with 10碌m level ultra-high manufacturing precision.



The TOPEM20 3D printer utilizes slurry extrusion lamination technology (SEL) to print battery slurry. It is capable for a wide range of printing materials, including:

  • lithium cobalt oxide LiCoO2 cathode slurry
  • lithium iron phosphate LiFePO4 cathode slurry
  • high nickel ternary cathode NCM8 11
  • graphite anode slurry
  • polymer solid electrolyte
  • polymer
  • oxide composite solid electrolyte
  • others


The TOPEM20 3D printer boasts ultra-high manufacturing precision of 10碌m. Equipped with intelligent integrated micron-level laser sensors and an automatic leveling system, it can achieve high-precision printing of complex-structured electrode layers and electrolyte layers while ensuring the integrity of each layer. It enables the rapid printing of special thick electrodes with continuous microchannel and microporous structures using positive and negative electrode materials. This capability plays a crucial role in enhancing battery performance and provides a broader scope for innovation.
