Researchers develop new method to 3D print lithium-ion batteries 3D-printed lithium-ion batteriesImage: Oct 20, Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries.
Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries, said researchers from Duke University and Texas State University in the US.
Most lithium-ion batteries on the market come in cylindrical or rectangular shapes, according to the study published in the journal ACS Applied Energy Materials.
When manufacturers design a product -- such as a cell phone -- they must dedicate a certain size and shape to the battery, which could waste space and limit design options. Theoretically, three-Dimensional 3D printing technologies can fabricate an entire device, including the battery and structural and electronic components, in almost any shape.
However, the polymers used for 3D printing, such as poly lactic acid PLAare not ionic conductors, creating a major hurdle for printing batteries. The researchers wanted to develop a process to print complete lithium-ion batteries with an inexpensive 3D printer.
They increased the ionic conductivity of PLA by infusing it with an electrolyte solution. In addition, they boosted the battery's electrical conductivity by incorporating graphene or multi-walled carbon nanotubes into the anode or cathode, respectively. To demonstrate the battery's potential, the team 3D printed an LED bangle bracelet with an integrated lithium-ion battery.
The bangle battery could power a green LED for about 60 seconds. According to the researchers, the capacity of the first-generation 3D-printed battery is about two orders of magnitude lower than that of commercial batteries, which is too low for practical use.
However, they say that they have several ideas for increasing the capacity, such as replacing the PLA-based materials with 3D-printable pastes.Lesson Plan 11 Electric Experiments Brief description Students experiment with aluminium foil, batteries and cheap, readily availably low voltage light bulbs* to construct a simple conductivity.
Which Battery Is Better? Abstract. Advertisers are always touting more powerful and longer lasting batteries, but which chloride paste (DK Science ). Ordinary dry cells are used in most flashlight batteries.
These dry cells use ammonium chloride as the electrolyte.
"Cells needed to supply heavier currents use "Cells and Batteries. The batteries can thus have high capacity for the same weight or alternately, for the same capacity, a vastly reduced weight -- which is an important attribute for transportation applications.
