3D printing unlocks freedom in mobile electronic device design
Energy storage is an integral part of mobile electronics. As mobile electronic devices become smaller and smaller, and their functions are gradually enhanced, the demand for batteries in mobile electronic devices is also increasing.
At present, mobile electronic device manufacturers still need to design their devices according to the size and shape of commercially available batteries. Most of the batteries are cylindrical or rectangular. These batteries occupy most of the space of modern electronic devices, limiting the Design freedom, especially for the next generation of flexible electronic devices, battery limitations have become a design issue.
The application of 3D printing technology in battery manufacturing is expected to solve this problem and produce "arbitrary" shaped batteries and supercapacitors. Not only that, the application of 3D printing technology will also improve the electrochemical performance of batteries. A review article from the journal Advanced Functional Materials-"Additive Manufacturing of Batteries" provides an overview of batteries implemented through different types of 3D printing technology and addresses the challenges that still exist in the industrial application of 3D printed batteries discuss.
The main 3D printing technologies for manufacturing batteries include: stereolithography (SLA), template-assisted electrodeposition-based 3D printing (TAE), inkjet printing (IJP), direct ink writing (DIW) ), Fused deposition forming (FDM) and aerosol jet printing (AJP). Materials include printed electrode materials graphene, carbon nanotubes, carbon nanofibers and LTO / LFP, as well as electrolyte materials.
3D printing, as an advanced manufacturing technology, produces complex 3D objects through digitally controlled deposition of phase change and reactive materials and solvent-based inks.
Good workability, low density, good corrosion resistance, good thermal performance, low weight. Titanium alloy has high strength and low density, good mechanical properties, and good toughness and corrosion resistance. In addition, the titanium alloy has poor processability and is difficult to cut, and it is very easy to absorb impurities such as hydrogen, nitrogen, nitrogen and carbon during hot working.
HP nylon PA12 is a kind of material that has very high strength and good heat resistance. HP has accumulated in the printing industry for a long time, which makes the multi-jet melt 3D printing technology using HP patented technology very suitable for small batch production. The polyamide PA12 molecular backbone contains a large number of polar amide groups, which causes a strong force between polyamide molecules and can form hydrogen bonds(the greater the density of hydrogen bonds, the better the mechanical strength, the more carbon atoms, the worse the strength), At the same time, the polyamide PA12 molecules are arranged neatly and crystalline; The polyamide PA12 molecular main chain section also contains methylene, which makes the polyamide PA12 flexible and can affect the polyamide PA12 melting point and vitrification temperature.
Good toughness, high hardness, production of hard functional components, production of high-quality components at very low unit cost, materials imported from the United States, with FDM certification (accessible food-grade materials). PA12GB and PA12 belong to engineering plastics. PA12GB has higher mechanical properties, dimensional stability, heat resistance and aging resistance.
