In recent years, the lithium battery industry has developed rapidly, with various large-scale new production lines and technologies constantly emerging, both in terms of investment quotas and technological innovation. Governments of various countries have also provided sufficient support to this industry.

　　Recently, there has been a new breakthrough in 3D printed lithium battery technology. Jennifer, a materials scientist at Harvard University? Lewis has developed a new type of functional ink. This type of ink is basically a colloidal suspension of the target material nanoparticles - the ink material is determined based on the object to be printed, for example: if you want to print lithium batteries, use lithium, and if you want to print wires, use silver.

　　The principle is that the high-pressure extruder squeezes ink to the predetermined position at room temperature. Ink solidifies during the printing process and quickly forms components, so simple batteries can be manufactured in just a few minutes.

　　Additionally, it is reported that the lithium-ion battery she printed is only 1 square millimeter in size, but its performance is on par with commercial batteries because Lewis can handle microstructures with an accuracy of up to 100 nanometers, and the structure is the same as larger batteries. In other words, this type of battery can not only replace traditional batteries, but also have a much smaller size. Considering the proportion of batteries in many devices nowadays, this news is undoubtedly a blessing for most custom lithium battery manufacturers and consumers.
