Graphene batteries

Solidion Technology, an advanced battery technology solutions provider, has announced that it has entered into a securities purchase agreement with a new institutional investor for the purchase and sale of 2,333,000 shares of common stock (or common stock equivalents) in a private placement priced above market under Nasdaq rules. The offering is expected to result in gross proceeds of $35 million, before deducting offering expenses. 

The Company intends to use the net proceeds from the offering to support the commercialization of its patented Extreme-Climate Battery technology, fulfill customer demand, expand inventory, advance the building and testing of prototypes, and for working capital and general corporate purposes.

Global Graphene Group has reported another sale of Solidion Technology shares, continuing a series of insider transactions involving the graphene-linked battery materials company. The latest filing shows the company sold 175,000 shares on June 4, 2026.

Following the sale, Global Graphene Group still held 1,569,695 shares of Solidion Technology.

Solidion Technology has announced a 'patented breakthrough' in extreme-climate battery technology and its strategic positioning within the rapidly expanding space and lunar economy. As commercial space activity accelerates, Solidion's Generation Extreme-Climate Battery (Gen-ECB) platform is engineered to deliver reliable, high-performance power storage for satellites, Low Earth Orbit (LEO)-based AI data centers, crewed spacecraft, and future lunar infrastructure.

Protected by multiple patents, Solidion's Gen-ECB harnesses the exceptional thermal conductivity and radiation resistance of graphene to actively regulate temperature within battery cells - rapidly dissipating heat to prevent thermal runaway and, when needed, drawing warmth from external sources such as solar panels to maintain stable operations in extreme cold. The result is a battery system proven to operate reliably from −80°C to +60°C, with ongoing development targeting even broader temperature ranges for deep-space missions.

Solidion Technology  recently reported its first-ever quarterly revenue in its Q1 2026 results, marking a step in the company’s transition from R&D-focused operations toward commercialization. The company recorded $85,426 in revenue, primarily from government grants and initial deliveries of its silicon anode materials.

While still operating at a loss, Solidion reduced its net loss to $1.4 million for the quarter, supported in part by lower operating expenses and a non-cash gain related to derivative liabilities. The company also reported a $1.8 million loss from continuing operations, reflecting ongoing investments in product development and commercialization.

Volt Carbon Technologies has provided an update on its operations, highlighting ongoing commercialization efforts and expanded activities in graphene-related materials.

Over the past three years, Volt has generated modest revenues through mineral processing services and advanced materials development programs, as reported in its Management’s Discussion and Analysis filings. While these revenues have not been material, they have helped offset a portion of operating costs as the company continues to prioritize process development and commercial readiness.

Solidion Technology, an advanced battery technology solutions provider, has announced that it has entered into an agreement with the IP Services Practice of Hilco Global to monetize its foundational energy portfolio and enforce its patent rights. 

Hilco has analyzed the Solidion patent portfolio to identify high value assets and the patent data suggest that a significant number of global companies will likely require a license to the Solidion portfolio. In the energy storage segment in particular, virtually all the major players in the industry have technology that overlaps with the Solidion portfolio and the same appears to be true in semiconductors, consumer electronics and aerospace.

Graphene Manufacturing Group (GMG) has provided a progress update on its Graphene Aluminium-Ion Battery technology (“G+A CELLS”) being developed by GMG and the University of Queensland (“UQ”) under a Joint Development Agreement with Rio Tinto, one of the world’s largest metals and mining groups, and with the support of the Battery Innovation Center of Indiana (“BIC”) in the United States of America.

The GMG G+A CELLS have reportedly demonstrated superior performance characteristics when compared to a representative market leading ultra-fast charging batteries, the Lithium Titanate Oxide (“LTO”) batteries, which can be sold at a premium price of up to US$1200/kWh.

The Graphene Flagship project GRAPHERGIA has launched the piloting phase of its three demonstration cases implementing graphene-based technologies for energy harvesting and storage in real-life applications.

The demonstrators' development began in March 2026 and aims to validate cutting-edge solutions in smart self-charging textiles and next-generation lithium-ion batteries for applications in healthcare, aerospace, mobility, and wearable electronics.

Grapherry has entered a collaboration with the University of Illinois Chicago to advance scalable graphene manufacturing for industry.

A key part of this partnership revolves around testing the quality of the graphene produced at Grapherry for application-specific properties such as electrical conductivity and structural characteristics. The goal is to work together to accelerate materials validation, application development, and pathways to industrial deployment across sectors such as energy storage, construction, agriculture, and advanced composites.

Researchers at Israel's Tel Aviv University recently demonstrated a single-step laser process that simultaneously fabricates and prelithiates silicon-graphene anodes under ambient conditions, delivering virtually zero capacity decay over thousands of high‑rate cycles. The method directly addresses two key problems of silicon anodes - large volume changes and first‑cycle lithium loss - without relying on reactive lithium metal, moisture‑sensitive reagents, or multi‑step ex situ prelithiation.

The process starts from a ternary blend of phenolic resin, silicon nanoparticles (SiNPs), and a common lithium salt such as LiOH, Li₂CO₃, LiNO₃, LiF, or LiClO₄. Low‑power laser irradiation under ambient atmosphere generates localized temperatures above 2000 K and pressures exceeding 1 GPa, converting the resin into a porous, conductive laser‑induced graphene (LIG) matrix while driving solid‑state reactions that prelithiate the silicon surface and form stable interfacial phases. The result is a self‑standing, additive‑free SiNP/LIG film in which each nanoparticle retains a crystalline Si core for high capacity, wrapped by a ~10 nm lithium silicate shell that compensates first‑cycle lithium losses and chemically anchors the particles to the graphene scaffold.
