Talga Resources has announced receiving firm commitments from investors to raise gross proceeds of A$10.0 Million (around USD$7.2 Million).

Talga shared that it sees the strongly supported placement as reflecting significant investor interest as the Company progresses development of its facility in Sweden to produce ultra-low emission coated anode for greener lithium-ion batteries.

NanoGraf, an advanced battery material company, has announced that it has partnered with the U.S. Department of Defense to develop a longer-lasting lithium-ion battery, designed to provide U.S. military personnel with better portable power for the equipment they rely on to operate safely and effectively. Nanograf's graphene-wrapped silicon anode cells are hoped to significantly improve equipment runtime in the field.

The Department of Defense will provide NanoGraf with $1.65 million to develop silicon anode-based lithium-ion technology in a format compatible with all portable batteries, with a goal of enabling a 50-100 percent increase in runtime when compared to traditional graphite anode lithium-ion cells.

Rice University scientists led by Prof. James Tour have turned adhesive tape into a silicon oxide film (mixed with laser-induced graphene) which replaces troublesome anodes in lithium metal batteries.

The researchers used an infrared laser cutter to convert the silicone-based adhesive of commercial tape into the porous silicon oxide coating, mixed with a small amount of laser-induced graphene from the tape’s polyimide backing. The protective silicon oxide layer forms directly on the current collector of the battery.

Scientists at EPFL have recently published a research that could open up new pathways to boosting the capacity of sodium-ion batteries. Lithium is becoming a critical material as it is used extensively in cell-phones and car batteries, while, in principle, sodium could be a much cheaper, more abundant alternative, says Ferenc Simon, a visiting scientist in the group of László Forró at EPFL. This motivated our quest for a new battery architecture: sodium doped graphene.

Since sodium is far more abundant than lithium, and the risk of fire is much lower with this battery chemistry, it is considered a potentially viable replacement to current lithium-ion technology. But sodium also has much lower energy density than lithium, which has so far limited uptake, particularly in the electric vehicle and consumer electronics segments, where the physical size of the battery is a deciding factor. EPFL's new work uses graphene to address this issue.

A team of Brown University researchers has found a way to double the toughness of a ceramic material used to make solid-state lithium ion batteries. The new strategy could be useful in bringing solid-state batteries to the mass market.

There’s huge interest in replacing the liquid electrolytes in current batteries with ceramic materials because they’re safer and can provide higher energy density, said Christos Athanasiou, a postdoctoral researcher in Brown’s School of Engineering and lead author of the research. So far, research on solid electrolytes has focused on optimizing their chemical properties. With this work, we’re focusing on the mechanical properties, in the hope of making them safer and more practical for widespread use.

Sweden-based 2D fab has recently closed a new share issue of approximately €700,000. The capital will primarily be used for developing the organization and for commercializing the Company's graphene products.

The share issue was directed to a limited number of investors, having received the offer either via the company's executive management or via G&W Fondkommission. Through this transaction 2D fab received eleven new owners, among them Malmö based Polynom Investment.

NanoGraf Technologies is a U.S-based battery material startup formerly known as SiNode Systems, established in 2012 to commercialize a novel graphene-enhanced silicon-based anode tech for lithium-ion batteries originally conceived at Northwestern University.

In light of the rising interest in graphene-enhanced batteries, and Nanograf's advances in this field, Graphene-Info was glad to exchange a few words with Dr. Francis Wang, Nanograf's CEO, to get a better image of the company's tech and future plans. Dr. Wang has accumulated over 20 years of experience in technology innovation and commercialization in the energy storage and clean energy spaces. Prior to NanoGraf Technologies, Wang was a founder and Director of Energy Storage Center at the National Institute of Clean Energy in Beijing, China. He has held positions in some of the world's largest battery, consumer products and energy companies, including Duracell, Procter & Gamble, Gillette, Boston Scientific and the Shenhua Group.

Australia-based battery graphene anode producer Talga has entered an agreement with European lithium-ion battery giant Farasis Energy Europe (Farasis). Talga will supply coated anode products for evaluation in Farasis batteries.

Talga sources its graphene and graphite in the north of Sweden, from where the company produces coated ‘active’ anode products which it will now, according to their agreement, supply to Farasis.

Researchers at the Graphene Integrated Functional Technologies (GIFT) Research Cluster at Queen’s University in Canada have developed a novel graphene-based flexible hybrid batterysupercapacitor device.

The device consists of high specific surface area electrodes paired with an electrolyte, which contains a redox species that can exist in more than two oxidation states. The two initially equal half-cells of the device consist of a reduced graphene oxide hydrogel which encapsulates vanadium ions, synthesized with a single-step method.
