A 3D printed li-ion battery

Posted on Updated on

I am concerned about writing anything related to Lithium. So I did research about it. I found out some favorable research about Lithium.
Please do the judgment for our reader’s.
According to Battery University, “Because of the inherent instability of lithium metal, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density, the lithium-ion system is safe, providing certain precautions are met when charging and discharging. Today, lithium-ion is one of the most successful and safe battery chemistries available. Two billion cells are produced every year”.

At the same time, according to Physics researchers at Virginia Commonwealth University,” they also found that the electrolytes in lithium-ion batteries (also known as Li-ion batteries) could be replaced with halogen-free electrolytes that are both nontoxic and environmentally friendly”.

According to Engadget,” A 3D printed li-ion battery is one of the challenges in creating smaller and smaller devices these days, such as wearables and phones, is that the batteries can take up a lot of room. Cases are often designed around standard battery sizes, and it often creates wasted space. Now, new research published in ACS Applied Energy Materials shows that it’s possible to 3D-print lithium-ion batteries into whatever shape you need”.

3D Print Metallic Glass

Posted on Updated on

 

Yale Professor Jan Schroers and his graduate students have developed some unique uses for metallic glasses, a particularly tough metallic alloy that can be molded into useful products (like cell phone cases) at relatively lower temperatures and pressures. According to Yale Professor Jan Schroers and his research team,” they used a new approach to 3D print objects from the metallic glass a relatively new material stronger than even the best metals, but with the pliability of plastic”.

3D printed active materials for robots

Posted on Updated on

3D printed active materials for robots, inspiration from invertebrates.

According to Dr. Ed Habtour, ARL researcher who specializes in nonlinear structural dynamics and lead author Ghazaleh Haghiashtiani, “Current military robots have two major limitations that restrict them from mimicking the locomotion of biological organisms. Unlike current 3-D printed DEAs, the new fabrication method does not require post-processing steps, such as assembly, drying or annealing. With the new 3-D printing method, the Solider can take advantage of the unique actuation properties of soft DEAs at the fundamental materials level with microscale resolution and complexity, with minimal prior expertise.”
