China develops micro flexible capacitors with high performance, safety

SHENYANG - Chinese researchers have developed new micro capacitors with high energy storage density and excellent thermal stability, according to Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

The lithium ion micro-capacitors (LIMCs) are mechanically flexible without performance degradation under repeated bending, and can operate safely even at temperatures of 80 degrees Celsius.

The ever-increasing boom in smart, miniaturized electronics has led to an urgent need for on-chip energy storage systems that exhibit high performance, safety, flexibility and robust integration.

The solid-state planar LIMCs can boost high voltage and capacitance and their high cycling stability allows them to maintain almost 99 percent of their capacitance after 6,000 electric cycles.

The micro devices are expected to be commercially available in 2022.
