Graphene batteries: Introduction and Market News - Page 2

Grapherry, a Chicago-based clean-tech materials company, has announced that it is expanding partnerships with battery companies to evaluate its waste-derived graphene for use in battery anode materials. The ongoing collaborations focus on assessing performance, scalability, and manufacturability of graphene-enabled anodes for next-generation energy storage systems.

Grapherry produces high-quality, cost-effective graphene from carbon waste using an IP-protected, continuous manufacturing platform designed for scale. The company’s approach addresses key industry challenges related to graphene adoption in batteries, including material consistency, supply scalability, and cost control.

India-based energy-tech startup Dreamfly Innovations has raised almost US$328,000 in non-dilutive venture debt from SIDBI. The proceeds will be used to support working capital and expand manufacturing capacity as the company scales operations.

Backed by Avaana Capital, Dreamfly Innovations designs and manufactures advanced smart battery systems for drones, aviation, and aerospace applications. The firm focuses on lithium solid-state and graphene-based batteries, built to deliver higher energy density, improved safety, and better thermal performance.

At CES 2026, Japanese startup 3DC showcased a new 3D graphene nanomaterial designed to improve fast-charging and high-power battery performance. The material, called Graphene MesoSponge (GMS), uses a porous, nanoscale structure that allows electrons to move more freely inside battery electrodes. Unlike flat graphene sheets, GMS forms a connected internal network, which 3DC says reduces resistance and improves charging efficiency.

Founded in 2022, 3DC is commercializing research that began nearly a decade earlier at Tohoku University. The company is backed by Open Innovation funding from Hyundai and is currently operating at pilot scale while working with global battery manufacturers.

Graphene-Info is pleased to announce that registration is now open for Graphene-Connect 2026, our flagship two-day virtual event dedicated to graphene industrialization and innovation, taking place online on 11–12 March 2026, in collaboration with Techblick.

Graphene-Connect 2026, preliminary agenda

Graphene-Connect tickets start at our special early bird price of $400 (with discounts available for group passes).

Event overview

Graphene-Connect 2026 is the must-attend worldwide meeting place for the graphene industry, bringing together the full value chain from material producers to end users. The live online format combines a curated technical program with advanced networking tools and virtual exhibition spaces, designed to make remote participation feel as close as possible to an in‑person conference.

World-class agenda

The agenda is jointly curated by Graphene-Info and Techblick, with talks spanning graphene materials, production processes, electronics, energy storage, composites, sensors, filtration, anti-corrosion coatings, concrete, textiles, neural interfaces and more. The program mixes visionary keynotes, industrial case studies, metrology and standards updates, as well as deep-dive technical talks, ensuring relevance for both R&D experts and commercial decision-makers.

Global Graphene Group has made a small sale of its shares in Solidion Technology, but it still holds a stake in the company. While the moves are worth noting, they do not seem to look like an exit or a loss of confidence by a major owner.

Global Graphene Group, which owns more than 10% of Solidion Technology (ticker: STI), sold a total of 1,318 shares in two small transactions earlier this month. These sales brought in about 10,374 dollars at prices around 7.87 dollars per share. After the sales, the group still holds about 1.74 million shares, so the sale is small compared with its overall position.

Graphene Manufacturing Group (GMG) has announced new test results for its graphene aluminium-ion battery, which the company says can recharge in roughly six minutes. GMG said the technology, known as the Graphene Aluminium-Ion Battery (G+AI), is being developed with the University of Queensland under a joint development agreement with Rio Tinto, with testing support from the Battery Innovation Center of Indiana in the US.

GMG reported that third-party testing by the Battery Innovation Center showed its current G+AI pouch cells achieved an energy density of 58 watt-hours per kilogram when charged in one hour and 26 watt-hours per kilogram when charged in six minutes. During six-minute fast charging, the cells reached 62% of capacity in 3.2 minutes and maintained performance over hundreds of cycles, according to the company. The cells had a nominal voltage of approximately 3.0 volts.

Talga Group has announced the successful completion of a A$14.5 million (around US$10 million) share placement to institutional and sophisticated investors, along with the launch of a Share Purchase Plan (SPP) offering eligible shareholders in Australia, New Zealand, and Singapore the opportunity to participate and raise up to an additional A$5 million (about US$3.3 million).

The funds raised will be used to progress engineering work for a staged expansion to 5,000 tonnes per year of anode production, supported by Talga’s recently awarded A$13.35 million (almost US$9 million) Industriklivet grant from Sweden.

Solidion Technology has announced that it is in the process of commercializing a pouch cell for specific use in industrial and military drones.

These pouch cells are said to have high power stability (a 9.5Ah pouch cell retains approximately 95% of capacity at 10c), which the Company says give sit a competitive edge, as most pouch cells on the market retain 78% of capacity at 5c, it claims.
