Graphene batteries: Introduction and Market News - Page 6

Researchers at China's Guilin University of Electronic Technology, China Nonferrous Metals (Guilin) Geology and Mining Co., Ltd., Dalian University of Technology and Reliability Physics and Application Technology of Electronic Component Key Laboratory have developed a method to enhance the energy storage performance of lithium-ion batteries, involving the modification of natural graphite through irradiation with a high-current pulsed electron beam (HCPEB).

The method relies on HCPEB to prepare self-supporting graphene without pollution irradiation. The team reported that graphite was instantaneously transformed into defective graphene structures and that the resulting graphene electrodes exhibited excellent lithium storage and cycling properties.

Skeleton Technologies recently closed a €108 million funding round that includes Siemens Financial Services (SFS), Marubeni Corporation and other investors. This funding will accelerate the development of next-generation products and finance the manufacturing expansion for supercapacitors and the company’s new high-power battery technology – the SuperBattery.

Skeleton Technologies’ CEO and Co-Founder, Taavi Madiberk, said: "Securing an investment from one of Europe's largest tech companies is a significant milestone for Skeleton. In addition to SFS’ investment, Siemens is also a key partner, supplier, and customer. Their expertise in industrialization and commercial partnerships will propel our growth and solidify our role in leading the energy transition”.

Researchers from China's Lanzhou University and Japan's Tokyo University of Science have harnessed the surface binding property and redox activity of platinum (Pt)-doped gold (Au) nanoclusters, Au₂₄Pt(PET)₁₈ (PET: phenylethanethiolate, SCH₂CH₂Ph), as a high-efficiency electrocatalyst in lithium–sulfur batteries (LSBs). 

Lithium–sulfur batteries (LSBs) can store three to five times more energy than traditional lithium-ion batteries and so they have emerged as a promising energy storage solution. LSBs use lithium as the anode and sulfur as the cathode, but this combination poses challenges. One significant issue is the “shuttle effect,” in which intermediate lithium polysulfide (LiPS) species formed during cycling migrate between the anode and cathode, resulting in capacity fading, low life cycle, and poor rate performance. Other problems include the expansion of the sulfur cathode during lithium-ion absorption and the formation of insulating lithium–sulfur species and lithium dendrites during battery operation.  While various strategies, such as cathode composites, electrolyte additives, and solid-state electrolytes, have been employed to address these challenges, they usually involve trade-offs and considerations that limit further development of LSBs.

Lyten has announced that it has signed a Memorandum of Understanding with Prime Minister Xavier Bettel, the Minister of Finance Yuriko Backes and the Minister of the Economy Franz Fayot to locate its European headquarters in Luxembourg. 

Lyten is also exploring opportunities to establish research and development capabilities in Luxembourg, including infrastructure to support collaboration with European customers on applications utilizing Lyten’s 3D Graphene platform. The facility would build on R&D in IoT sensing that Lyten already has ongoing in Luxembourg with an industry partner for the mobility sector.

Dreamfly Innovations, a graphene battery startup, has secured $300,000 in funding through a round led by Rebalance Angel Community, with participation from IIM Ahmedabad’s CIIE.CO (Center for Innovation Incubation and Entrepreneurship). 

The startup intends to utilize this capital for product commercialization and expanding its team. Dreamfly’s primary objective is to revolutionize the future of energy by employing software-defined battery (SDB) technology.

Graphene Manufacturing Group (GMG) has announced it has developed graphene aluminum ion (G+AI) battery prototype pouch cells with a storage capacity of more than 500 milliampere hours (mAh) and a nominal voltage of about 2 volts.

GMG sees this as a significant development because it demonstrates how it has matured its battery electro-chemistry and assembly techniques to produce pouch cells with more than 10 layers of graphene-coated cathode and aluminum foil anode. The next step is for the company to optimize the assembly techniques of the pouch cell prototypes to achieve repeatable storage capacity of more than 500 mAh cells for the purpose of conducting a variety of standard testing conditions for comparison purposes.

BASF, a global battery materials producer, and Nanotech Energy, a developer of graphene-based energy storage products, have agreed to partner to significantly reduce the CO₂ footprint of Nanotech’s lithium-ion batteries for the North American market. The agreement aims to close the loop for lithium-ion batteries in North America, with BASF producing cathode active materials from recycled metals in Battle Creek, Michigan, for the usage in lithium-ion battery cells produced by Nanotech Energy. Feeding recycled metals into the production of new lithium-ion batteries can reportedly reduce the CO₂ impact of batteries by about 25% compared to the use of primary metals from mines.

Both companies will additionally partner with American Battery Technology Company (ABTC), a lithium-ion battery recycling company in Reno, Nevada, and TODA Advanced Materials Inc. (TODA) with decades of experience in manufacturing specialized pCAM (precursor for Cathode Active Material) and metal hydroxide material located in Ontario, Canada, to establish such a localized battery value chain for the North American consumer electronics and automotive industries. Along that chain, battery scrap and off-spec material from Nanotech’s pilot operation in Chico, California, as well as from its planned commercial facility will be recycled by ABTC. The battery-grade metals as recovered by ABTC – such as nickel, cobalt, manganese, and lithium – will be subsequently used by TODA and BASF to produce new precursors and cathode active materials, respectively. Nanotech will then use these materials again in its battery cell production – overall, a truly circular economy in North America.

Lyten has announced it has raised $200 million as part of its over-subscribed Series B funding round, to scale manufacturing and commercialize its first three product lines: Lithium-Sulfur batteries, lightweight composites, and next generation IoT sensors.

The round is led by Prime Movers Lab, a venture capital firm focused on investments in breakthrough scientific startups and has $1.2B in assets under management. Prime Movers Lab is joined with significant participation from strategic investors and sector leaders Stellantis (previously announced), FedEx Corporation, Honeywell, and Walbridge Aldinger Company. Additional strategic, venture capital and individual investors make up the remainder of the round.

NanoXplore and its wholly owned subsidiary, VoltaXplore, a silicon-graphene-enhanced Li-ion battery manufacturer for the Electric Vehicle and grid storage markets, have announced that VoltaXplore has agreed on commercial terms for the supply of Li-ion battery cells with a well-known commercial vehicle OEM. 

The batteries include graphene in the anode (graphene-silicon additives) and battery cells will reportedly be produced in VoltaXplore’s gigafactory starting from 2026. The agreement is for 1 GWh per year for a duration of 10 years following a pricing formula that passes through raw material cost to the customer.
