Researchers at Duke University and Texas State University say manufacturers have so far had to design their devices around the size and shape of commercial batteries. Most lithium-
According to research published in the Journal of ACS applied energy materials, ion batteries on the market are cylindrical or rectangular.
When the manufacturer designs the product-
For example, a mobile phone-
They have to provide a certain size and shape for the battery, which can waste space and limit the design options.
In theory, three
Size (3D) printing technology can make an entire device in almost any shape, including batteries, structures, and electronic components.
However, polymers used for 3D printing, such as PLA (PLA), are not ion conductors, creating a major obstacle for printing batteries.
Researchers hope to develop a way to print complete lithium
Ion battery with cheap 3D printer.
They improve the ion conductivity of PLA by injecting PLA with electrolyte solution.
In addition, they increase the conductivity of the battery by adding graphene or polygraphene
The wall carbon nanotubes enter the anode or cathode respectively.
To demonstrate the potential of the battery, the 3D team printed an LED bracelet with integrated lithiumion battery.
The bracelet battery can power the green LED for about 60 seconds.
According to the researchers, firstgeneration 3D-
The printed battery is about two orders of magnitude lower than the commercial one, which is too low for actual use.
However, they say they have several ideas for increasing capacity, such as replacing the PLA
