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.

Trans2Dchem project to develop improved graphene-based supercapacitors

TRANS2DCHEM, or “Transition of 2D chemistry-based supercapacitor electrode material from proof of concept to applications”, is a project that received € 2,485,717 from the EIC to create supercapacitors with increased energy density (above 50 Wh/L, which is about twice as much as the best components on the current market).  This will allow their widespread use in electric cars as well as a battery support in devices that need to be supplied with large amounts of energy in a very short time.

The researchers involved in the project utilize highly nitrogen doped graphene material (SC-GN3), offering energy density up to 200 Wh/L at a power of 2.6 kW/L, 170 Wh/L at 5.2 kW/L, and 143 Wh/L at 52 kW/L. The international team is developing supercapacitor prototypes, with manufacturing techniques that adhere to industry standards of leading supercapacitors manufacturers.

Researchers develop method for the fabrication of mesoporous graphene for energy storage systems

Researchers from South-Korea's Pohang University of Science and Technology (POSTECH), Kumoh National Institute of Technology, Sungkyunkwan University, Yeungnam University, Konkuk University and University of Seoul have proposed a simple strategy for the fabrication of mesoporous graphene with applications in high-performance energy storage systems like electric double-layer supercapacitors (EDLCs).

Conventional energy storage systems made of activated carbons (ACs) tend to have a poor power density due to the insufficient specific contact area, leading to inadequate creation of an electric double layer between electrode material and electrolyte. Therefore, an active material with a high specific contact area could help obtain high energy densities and meet the needs of various energy storage systems. Graphene's remarkable electrical conductance naturally makes it a logical candidate, but the high van der Waals contact between the graphene sheets makes stacking unavoidable, producing a limited available surface area.
