Skeleton Technologies secures €4 million investment for development of graphene supercapacitors

Jan 28, 2016

Skeleton Technologies logoSkeleton Technologies, the graphene-enhanced supercapacitor manufacturer, has received a €4 million investment from KIC InnoEnergy, an investment company dedicated to promoting sustainable innovation and entrepreneurship in Europe’s energy industry.

The €4m investment from KIC InnoEnergy will be used to further develop the competitive advantage of Skeleton Technologies’ supercapacitors. The company aims to reach the ambitious target of 20 Wh/kg energy density for its technology by 2020. The company will use the funds to further optimize electrode and cell design to allow for higher working voltages.

Rice University creates flexible and efficient solid-state microsupercapacitors

Dec 09, 2015

Rice University researchers have configured their previous invention of Laser Induced Graphene (LIG) into flexible, solid-state microsupercapacitors that rival current leading ones for energy storage and delivery.

The LIG microsupercapacitors reportedly charge 50 times faster than batteries, discharge more slowly than traditional capacitors and match commercial supercapacitors for both the amount of energy stored and power delivered. The devices are made by burning electrode patterns with a commercial laser into plastic sheets in room-temperature air, eliminating the complex fabrication conditions that have limited the widespread application of microsupercapacitors. 

Sunvault Energy and Edison Power Company to Kickstart graphene-based smartphone battery case prototype

Nov 30, 2015

Sunvault-logoSunvault Energy announced that it, in conjunction with the Edison Power Company, has completed the development of a graphene-enhanced Smartphone Battery Case that is built initially for the IPhone. Smartphone case designs for major brands such as LG and Samsung and other Smartphone manufactured devices are to follow shortly. The Company will be submitting this prototype for certification and verification.

The Battery Case will provide approximately 5000 mAh (milliamp hours) of energy to the first prototype IPhone model. The case will charge in roughly 3 minutes and will provide approximately 200% of additional power for most smartphones that are in the average 2400 mAh battery range. In addition to the fast charging, the case will not experience or generate any significant heat, and will have the unique attributes of both a battery and supercapacitor. Additional attributes will include superior cycles that will go far beyond the Lithium Ion spec of 500 cycles of charge / discharge before battery requires replacement. It will also be considerably lighter than current products on the market. The Company will start by focusing on the top Smartphone lines, which include: Samsung, Apple IPhone, Lenovo, LG, Huawei, Xiaomi and Sony.

Graphene 3D Lab Introduces a new product: Graphene Flex Foam

Nov 24, 2015

Graphene 3D Lab has announced Graphene Flex Foam, a new commercial product that will be available through Graphene Laboratories’ e-commerce site, Graphene Supermarket. The new product is described as a Multilayer Freestanding Flexible Graphene Foam, that brings together a conductive elastomer composite with ultra-light graphene foam.

The foam, a highly conductive 3D chemical vapor deposition (CVD), together with the composite, brings together the best of several worlds of graphene usage. As a flexible foam, the material is both lightweight and reconfigurable, adding to ease of use and handling, with a porous structure. The Graphene Flex Foam could be used in conjunction with other graphene-related materials–such as Graphene 3D Lab’s filament offerings–in the creation of electronics and other conductive products.

Graphene and metal nitrides create improved asymmetric supercapacitors

Nov 19, 2015

Researchers at A*STAR have developed an 'asymmetric' supercapacitor based on vertically aligned graphene nanosheets coated with iron nitride and titanium nitride as the anode and cathode, that could be a viable energy storage solution.

While traditional supercapacitors use the same material for both electrodes, the anode and cathode in an asymmetric supercapacitor are made up of different materials. Scientists initially used metal oxides as asymmetric supercapacitor electrodes, but as metal oxides do not have particularly high electrical conductivity and become unstable over long operating cycles, it was clear that a better alternative was needed. 

The Chinese CRRC develops graphene supercapacitors for public transportation

Oct 12, 2015

The CRRC, the Chinese state owned rolling stock manufacturer and the world's largest train builder, has developed graphene-based supercapacitors that can power electric buses with higher efficiency and for a longer period. 

The CRRC has reportedly produced two types of capacitors, a 2.8 Volt/30,000 F capacitor and 3 Volt/12,000 F one. The former is said to be able to power trolley buses for up to 10 km after a one-minute charge, compared with 6 km in the previous generation. The latter one can provide enough electricity to power a tram for 6 km with only 30 seconds of charging.In addition to improvements in performance, the new products are also more energy-saving and environmentally friendly. 

Skeleton Technologies' graphene supercapacitors to power Estonian unmanned ground vehicle

Sep 15, 2015

Skeleton Technologies is to supply graphene-based supercapacitors to Milrem's multipurpose UGV (unmanned ground vehicle) to be showcased at DSEI 2015. Milrem (Military Repair, Engineering and Maintenance) is an Estonian company whose mission is to be a partner in the defence and security sector, offering flexible product development solutions and full life cycle support for heavy vehicles. Milrem is also developing a mobile command post and an unmanned tracked vehicle for military purposes.
