Researchers from the University of Hyderabad (UoH) and the Tata Institute of Fundamental Research (TIFR) have developed electrode materials made of Tin antimony alloy based reduced graphene oxide composite which has the potential to enhance energy storage for sodium-ion batteries.

Sodium-ion batteries could offer enhanced energy efficiency, rapid charging capabilities, resilience to extreme temperatures, and safeguards against overheating or thermal runaway incidents. They exhibit reduced toxicity due to their lack of reliance on lithium, cobalt, copper, or nickel, which have the potential to emit environmentally harmful gases in the event of fire, according to a recent official release.

Researchers at Texas A&M University recently discovered that when charging a supercapacitor, it stores energy and responds by stretching and expanding. This insight could be help design new materials for flexible electronics or other devices that need to be both strong and store energy efficiently.

The team measured stresses that developed in graphene-based supercapacitor electrodes and correlated the stresses to how ions move in and out of the material. For example, when a capacitor is cycled, each electrode stores and releases ions that can cause it to swell and contract. According to the team, this repeated motion can cause the build-up of mechanical stresses, resulting in device failure. To combat this, the research looks to create an instrument that measures mechanical stresses and strains in energy storage materials as they charge and discharge.

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".

HydroGraph Clean Power, a manufacturer of graphene, has announced it is expanding its application development capabilities to meet growing global demand by establishing a partnership with the University of Manchester’s Graphene Engineering Innovation Center (GEIC) commencing in October of 2023. 

This strategic collaboration will aim to significantly enhance and ‘de-risk’ HydroGraph's application development capabilities. The GEIC, formed to commercialize graphene-related technologies and products, specializes in rapidly scaling up applications involving composites, building materials, membranes, inks, and coatings. To support their mission the £60 million GEIC facility was established with significant lab and engineering space that houses state-of-the-art testing and application development equipment, supported by experienced and knowledgeable team. Hydrograph will scale up this critical application development work by leveraging the resources at the GEIC with a team of commercially focused scientists and engineers to support industry adoption of its "99.8% pristine fractal graphene".

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/cm^2.

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.

The University of Manchester has entered a partnership with Abu Dhabi-based Khalifa University of Science and Technology, with the aim to deliver a funding boost to graphene innovation. Professor Dame Nancy Rothwell, President & Vice-Chancellor of The University of Manchester, and Professor Sir John O’Reilly, President of Khalifa University  officially signed a contract between the two institutions during a VIP visit by a Manchester delegation to the United Arab Emirates (UAE). 

This international partnership will further accelerate Manchester and Abu Dhabi’s research and innovation into graphene and other 2D materials. The Research & Innovation Center for Graphene and 2D Materials (RIC-2D), based in Khalifa University, is part of a strategic investment program supported by the Government of Abu Dhabi, UAE. This partnership will expedite the development of the RIC-2D at Khalifa University as well as help building capability in graphene and 2D materials in collaboration with Graphene@Manchester, a community that includes the academic–led National Graphene Institute (NGI) and the commercially-focused Graphene Engineering Innovation Centre (GEIC), a pioneering facility already backed by the Abu Dhabi-based renewable energy company Masdar.
