Graphene batteries: Introduction and Market News - Page 15

Canada-based NEO Battery Materials, focused on battery metals and materials, recently stated its plan to use graphene in its batteries.

Neo Battery Materials said in a recent announcement that it "intends to implement graphene as a conductive additive when manufacturing the silicon anode materials and as a potential candidate as a nanocoating layer to enhance cycling durability. The conductive additive improves the electrical conductivity of the active material (i.e., silicon and/or graphite) and is an essential component along with the binder and active material to fabricate the end-product anode".

U.S-based graphene batteries developer Nanotech Energy is reportedly planning to expand its facilities and develop a 517-acre campus within the Tahoe Reno Industrial Center. The first building is slated to open in Q4 2022.

The high-volume facility will significantly increase Nanotech Energy’s manufacturing capacity to produce and scale its patented, non-flammable Graphene-Organolyte batteries and other graphene-powered products, including EMI (electromagnetic interference) shielding, transparent conducting electrodes, conductive inks, conductive adhesives and silver nanowires.

Three companies in China recently launched graphene-enhanced lead-acid batteries, and they claim the graphene materials boost the performance of the batteries. While it is hard to verify the exact content and composition of these batteries, it seems as if graphene is finally starting to enter the battery market.

First up is Tianneng battery, which offers its TNEH Series Deep Cycle Black Gold Battery. The company says that the graphene expands the cycle life of the batteries and improves the performance at low temperatures. The TNEH series offers a 20% longer cycle life compared to the company's non-graphene batteries. The same battery also offers a 5% increase in capacity at low temperatures.

California-based company Lyten has developed a graphene-enhanced lithium-sulfur battery for electric vehicles. The battery reportedly achieved a higher gravimetric energy density than traditional lithium-ion and solid-state technologies. Lyten is said to have has previous collaborations with the US government for military projects.

The product was named LytCell EV and was designed to deliver three times the energy density of conventional lithium-ion batteries. The company reported 900 Wh/kg, precisely three times as much as the batteries in circulation today. Lyten Sulfur Caging is the name of the technology used in LytCell batteries to unlock the performance potential of sulfur by halting the advance of polysulfide, a cycle-life compromising factor that has so far prevented the practical use of Li-S in electric vehicles battery powered. Based on testing, a LytCell prototype reportedly proved to withstand more than 1,400 cycles very well.

Graphene Manufacturing Group (GMG) has announced that it has signed a non-binding Letter of Intent, with the aim to agree on the terms of binding agreements, with Robert Bosch Australia ("BOSCH"). The idea is for BOSCH to design and deliver a Graphene Aluminium Ion Battery ("G+AI Battery") manufacturing plant.

Robert Bosch Australia is a subsidiary of the BOSCH Group, a global provider of integrated production line solutions, automation, robotics and testing equipment. BOSCH will support GMG in learning and developing the automation of the battery assembly process and use the results from the GMG G+AI Battery pilot plant to support the scaling of these into fully automated plants. The parties' intent is for BOSCH to become GMG's engineering, design and construction contractor for GMG's near and long-term battery cell manufacturing facility needs (both coin cell and pouch pack).

Electric two-wheeler brand Yadea recently unveiled a number of products and innovations at its New Tech Launching Event, held in Wuxi, China. Among the achievements on display were Yadea’s Graphene 3.0 Battery, which the Company aims to to use to advance its electric two-wheeler technology.

Yadea’s Graphene 3.0 Battery reportedly boasts ultra-low temperature resistance, improved battery capacity and a high level of durability. The Company explained that it has added antifreeze electrolyte into the battery, which can dynamically adapt to different environmental conditions, adjust the battery temperature, and ensure that electric vehicle mileage doesn’t decline in winter. At the same time, the battery is said to be resistant to extreme temperatures and can handle ranges from -20°C to 55°C.

Foxconn has signed an agreement with Appear Inc to scale up Appear's fast charging graphene battery technology, for both consumer products and electric vehicles.

The two companies will collaborate, and Foxconn will provide its smart manufacturing and product development capabilities while Appear will provide the battery technology and IP.

Researchers from Chalmers University of Technology, Sweden, Accurion GmbH, Germany and Institute of Organic Synthesis and Photoreactivity (ISOF) at the National Research Council of Italy have presented a novel concept for fabricating high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world's most common and cheap metal ions sodium. The results of their study show that the capacity can match today’s lithium-ion batteries.

Sodium, unlike lithium, is an abundant low-cost metal, and a main ingredient in seawater. This makes sodium-ion batteries an interesting and sustainable alternative for reducing our need for critical raw materials. However, one major challenge is increasing the capacity. At the current level of performance, sodium-ion batteries cannot compete with lithium-ion cells. One limiting factor is the graphite, which is used as the anode in today’s lithium-ion batteries.

lithium ion batteries used in extreme heat or cold can be prone to malfunctions and low performance. Purdue University engineers have developed a solution: a "thermal switch" made of compressible graphene foam, that dynamically adjusts to temperatures both inside and outside the device to maintain consistent thermal management.

As electronic devices get smaller and more powerful, managing heat becomes a more crucial issue, said Xiulin Ruan, professor of mechanical engineering, who studies nanoscale heat transfer and sustainable energy. Most devices use passive thermal management, such as conduction and convection, to move excess heat. But this system isn’t tunable or adjustable, and doesn’t help at all in cold conditions.
