Solidion Technology, an advanced battery technology solutions developer, began trading on NASDAQ (ticker symbol “STI”) on February 5, 2024. Solidion is the merged entity between Honeycomb Battery Company (HBC, Dayton, Ohio) and Nubia Brand International Co., a special purpose acquisition company (SPAC), based in Dallas, Texas.

Some see electric vertical takeoff and landing (eVTOL) aircraft as the next urban transportation technology breakthrough. At the heart of an eVTOL aircraft is a heavy battery pack. The amount of energy that can be stored in a battery pack with a reduced mass must be significantly increased before the eVTOL industry can literally take off. It is estimated that eVTOL aircraft needs a battery system with a gravimetric energy density > 400 Wh/kg. For an air taxi to carry more passengers, a battery cell energy density higher than 450 or even 500 Wh/kg will be required.

Graphene Manufacturing Group (GMG) reported its financial results for the Q4 2023 - with revenues of around $36,000 USD and a net loss of around $1.88 million. The company has about $2.35 million in cash and equivalents.

The company recently provided a progress update on its Graphene Aluminum-Ion Battery technology project, and also on the commercialization of Nu-Calgon's product, powered by GMG Graphene.

HydroGraph Clean Power has announced that it has closed the second tranche of its non-brokered private placement for aggregate gross proceeds of C$962,600 (about USD$712,200). 

HydroGraph intends to use the proceeds for application development, business development and general working capital purposes. The Company looks forward to closing the final tranche of the offering by the end of February and is confident the aggregate proceeds will exceed the CAD$2,000,000 (around USD$1,479,000) target.

Last year, Global Graphene Group (G3) announced plans for its subsidiary, Honeycomb Battery, to merge with a SPAC company (Nubia Brand International Corp.) in a deal worth $925 million. Earlier this month, it was announced that this business combination was completed.

Upon the completion of the business combination, the combined company was renamed Solidion Technology. Beginning on Monday, February 5, 2024, Solidion’s common stock was expected to begin trading on the NASDAQ Global Market under the new ticker symbol “STI.”

According to a recent press release, Rimere, a company specializing in climate solutions, has closed a $10 million strategic investment from Clean Energy Fuels Corp., aimed at advancing the development and field testing of its proprietary plasma technology. This technology is designed to reduce emissions from natural gas infrastructure and facilitate the production of clean hydrogen and graphene.

The investment will accelerate the deployment of Rimere’s two devices, the Reformer and the Mitigator. The Reformer employs a sequential hybrid plasma process to convert natural gas into hydrogen and high-quality graphene, a process that remarkably does not produce CO₂ emissions. In particular, when renewable natural gas is utilized, the hydrogen generated can achieve a negative carbon intensity rating.

Canada-based Evercloak, that aims to turn the theoretical potential of membrane-based dehumidification into a viable commercial option with its method of manufacturing graphene composite membranes at scale, has announced that it has raised CAD$2 Million (around USD$1,475,000) in an oversubscribed seed round of investment, driven by interest in its HVAC technology. 

By reducing the amount of electricity required to dehumidify air — the most energy-intensive part of cooling — Evercloak’s membrane-based solution can cut the energy demands of air conditioning in half.

Today we published a new edition of our Graphene Investment Guide, with all the latest information and financial updates from public graphene companies. The recent year has been very challenging for many graphene companies - and also for graphene investors. Almost all the 23 public graphene companies we track show their share price decline in the previous year. 

It is a time of consolidation in the industry - and investors should be careful when looking at early stage graphene companies. Most graphene companies struggle to generate meaningful revenues, and we expect consolidation and liquidation to continue,.

The Graphene Investment Guide includes:

• An introduction to graphene
• An overview of graphene's most exciting applications
• An analysis of graphene's potential
• Market forecasts from leading analysts
• Detailed descriptions and financials of all public graphene companies
• Over 80 financial reports and company presentations (premium edition only)
• Graphene-Info's own investment thesis and action plan

Any technology-driven investor that wishes to stay current on the most promising new nanotechnology should look into this report. The report includes extensive data and information needed to launch a successful strategic graphene investment portfolio.

Directa Plus reported its preliminary financial results for 2023, saying that revenue grew to about €11 million and its loss reduced by about 20% from 2022.

Directa Plus says that it has made strong progress in 2023, as it secured new contracts across key geographies and in all verticals, including a €5.5 million three-year deal with Liberty Galati.

Lyten has announced it has secured a $4 million grant from the U.S. Department of Energy (DoE) to accelerate the manufacturing of its advanced lithium-sulfur battery technology. This grant (awarded by the DoE’s Energy Efficiency and Renewable Energy / Vehicle Technologies Office) specifically targets lithium-sulfur technologies that can alleviate offshore supply chain risk for EV batteries and increase EV driving range.

Lithium-sulfur is a chemistry known for decades to potentially hold 2 to 3 times the energy density of lithium-ion but was not envisioned to come into the market until the 2030s due to material science challenges. Lyten set out to accelerate this timeline by using its 3D Graphene material to develop a sulfur-graphene composite cathode. In June 2023, Lyten opened a semi-automated lithium-sulfur pilot line producing pouch and cylindrical cells on its 145,000-square-foot campus in Silicon Valley and will begin to deliver non-EV cells commercially in 2024.

University of Massachusetts Amherst researchers have received an award to develop a graphene-based sweat monitor tattoos that can be applied to the skin just like a temporary tattoo and assess the molecules present, such as cortisol. The tattoos will aim to give users better insight into their health and serve as a tool for researchers to discover new early indications of diseases.

“There are a lot of vital biomolecules that are present in sweat that we need to measure to really understand overall human performance and correlation to different diseases,” says research lead and assistant professor of biomedical engineering, Dmitry Kireev.
