Researchers develop customizable graphene e-textiles

A research team, led by Soongeun Kwon from the Department of Nano Manufacturing Technology at the Korea Institute of Machinery and Materials (KIMM) and Professor Young-Jin Kim from the Department of Mechanical Engineering at the Korea Advanced Institute of Science and Engineering (KAIST), has reported the development of customized graphene-based e-textiles.

Unlike most conventional methods that rely on toxic chemicals or optical masks for patterning, the research team used laser-direct patterning technology to create laser-induced graphene (LIG) on e-textiles. This approach led to the production of graphene-based e-textiles. The team converted raw Kevlar textiles to electrically conductive laser-induced graphene (LIG) via femtosecond laser pulses in ambient air.

Researchers develop rGO-enhanced structural supercapacitors

Researchers from the University of California San Diego and the University of Southern Mississippi recently designed a graphene-enhanced structural supercapacitor. Structural supercapacitors hold promise to expand the energy capacity of a system by integrating load-bearing and energy-storage functions in a multifunctional structure, resulting in weight savings and safety improvements. 

As a proof of concept, the researchers used their structural supercapacitor to build a miniature solar-powered boat. The supercapacitor was molded to form the boat’s hull and then fitted with a small motor and circuit. The circuit was connected to a solar cell. When exposed to sunlight, the solar cell charges the supercapacitor, which in turn powers the boat’s motor. In tests, the boat was able to cruise across the water, demonstrating the efficacy of this innovative energy storage solution.

Astra Energy announces agreement with Sustainable Energy Technologies for graphene/lithium-ion supercapacitors

Astra Energy has announced a strategic partnership agreement with Sustainable Energy Technologies (”SETI”) to supply Astra with the SETI Power Pack (SPP), the Company’s next generation energy storage solution that is a hybrid Graphene/Lithium-ion Supercapacitor intended to replace the need for traditional batteries.

In the PR, it was stated that: "When coupled with SETI Power Packs, the Holcomb Energy Systems (“HES”) In-Line Power Generator (“ILPG”) and the HES Self-Sustaining Power Plant in particular, are optimized to provide the end user with near continuous energy generation capability. Installing SPPs in series with an ILPG will enhance the overall effectiveness across the charge and discharge cycles, resulting in maximized operating efficiency of the HES Self-Sustaining Power Plant".

Skeleton & Martinrea to collaborate on batteries for refuse trucks

It was recently reported that Skeleton Technologies and the Canadian automotive supplier Martinrea International are cooperating to equip refuse collection vehicles for use in Paris and New York with Skeleton’s ‘SuperBattery’ technology.

Martinrea International develops and produces electric vehicle technologies for heavy-duty commercial vehicles through its subsidiary Effenco. The aim of the agreement with the Estonia-based Skeleton is to electrify fleets of refuse collection vehicles in Europe and North America, starting in New York City and Paris, and later to make the solution developed by both companies available worldwide. In autumn 2022, Shell had already become known as the first major customer for the graphene battery solution. Shell wants to use it to create electrification solutions for mining sites.

Researchers develop graphene/MoS2 micro-electrochemical capacitors for ultra-high charge storage

Researchers from the Indian Institute of Science have developed ultramicro-electrochemical capacitors with two-dimensional (2D) molybdenum disulphide (MoS2) and graphene-based electrodes. The development has great potential for wearables and implantable electronics as well as for sensors and miniature “smart” technology. 

The miniature energy storage device uses graphene Flakes and MoS2 alternately in each electrode - the cathode and anode. Gel was used as the electrolyte, which makes it possible to integrate micro-supercapacitors into chips. This would be difficult if not impossible with a water-soluble electrolyte. The capacitor showed a capacitance of 1.8 mF/cm2 for a single-layer structure (graphene-MoS2). The multilayer electrode structure, consisting of multiple alternating layers of graphene and molybdenum disulfide, gained 30 times greater capacitance, or 54 μF/cm2.

The Graphene Flagship's chief, Prof. Jari Kinaret, shares his views on the latest graphene development and the post-Flagship future

The Enlit Europe 2022 energy conference recently took place, and the Graphene Flagship participated, showing some of the latest energy-related graphene projects. We took the chance to discuss graphene with some of the flagship researchers, and we also talked to Prof. Jari Kinaret, the director of the flagship project, to learn of how he summarizes the last 10 years now that the flagship project will soon end.

Q: We understand that the Graphene Flagship is attending Enlit Europe 2022, showing some new graphene R&D projects. We'll be happy to get an overview of what will be displayed at the event.

At Enlit Europe, the Graphene Flagship exhibited innovations from its Spearhead Projects, which are industry-led initiatives working to move materials from research labs towards commercial applications. Among these initiatives are:

  • CircuitBreakers, led by ABB and developing first-of-their-kind grease-free, maintenance-free, low-voltage circuit breakers for fault protection in key parts of the electrical grid;
  • GRAPES, led by Enel Green Power and working on combining silicon solar cells with perovskite solar cells, paving the way for low-cost, highly efficient photovoltaic energy, surpassing the limits of silicon based cells.
