Solid battery shape have to pick? Korea Printed Battery Technology PRISS

Scientists at Ulsan University of Science and Technology (UNIST) in South Korea invented PRISS, a new solid state battery technology that can be printed in a variety of shapes and demonstrated the normal operation of solid state cells in the shape of letter, heart and paper glasses that are printed with this technology. Drive LED light. This technology can print solid state batteries into different shapes, embed different surfaces as needed and provide excellent endurance, at a very affordable cost.

Traditional batteries usually use electrolyte, chemical reaction occurs to damage the battery cathode. Replacing the electrolyte with a solid ionic conductor improves the stability and service life of the battery. The so-called "all-solid-state battery" is a battery that uses a solid electrode and a solid electrolyte and has many advantages over the liquid electrolyte battery. Researchers have eliminated the need for conventional separators to allow solid electrolytes that can be printed in a variety of shapes to act as a conducting medium.

Professor Sang-Young Lee of Ulsan University of Science and Technology said that "the new solid electrolyte can be cured under ultraviolet radiation and can replace the separator to achieve charge and discharge." Therefore, after the surface is printed with a layer of solid electrolyte, it is exposed to ultraviolet rays, No need to add diaphragm. The printed battery can be printed layer by layer on any surface and made in various shapes. The PRISS technology produced by solid-state battery performance are also in line with traditional batteries, charging and discharging process did not appear significant loss. Keep 90% of the battery power and achieve 30 cycles.

R & D personnel are planning to further increase the battery life, as well as increase its energy density. And research can be printed directly to the clothes on the battery. This technology will be heavily used in wearable electronics and IoT products.
