Micro-supercapacitors are a promising alternative to micro-batteries because of their high power and long lifetime. They have been in development for about a decade but until now they have stored considerably less energy than micro-batteries, which has limited their application. Now researchers have developed an electrode material that means electrochemical capacitors produce results similar to batteries, yet retain their particular advantages.

With the development of on-board electronic systems and wireless technologies, the miniaturization of energy storage devices has become necessary...
