Japanese researchers have developed a lithium-ion (Li-ion) capacitor with enhanced discharge properties and capacity.

Scientists from the graduate school of the Tokyo University of Agriculture and Technology claim the component's energy density of 45 Wh/L is four-and-a-half times higher than that produced by electronic double layer capacitors (EDLC) which use activated carbon, Tech-On reports.

Previous advances from the academic insitituion in Li-ion, whose negative electrodes are made from a combination of carbon nanofibre and lithium titanate, are set to reach the global electronics market.

Nippon Chemi-con has announced it will begin sending samples of the component, whose advantages include a lower likelihood of producing dendrite and lower temperature properties than EDLC's, during spring 2011.

Researchers at the university, part of the institution's vast Faculty of Technology, along with Nippon Chemi-con believe the capacitors can be incorporated into Li-ion rechargeable batteries used in many consumer electronics products such as laptop computers and camcorders.
