Researchers develop deformable graphene-based liquid metal micro-supercapacitors

Researchers from Pohang University of Science and Technology (POSTECH), Korea Institute of Industrial Technology and Konkuk University have fabricated highly deformable graphene-based micro supercapacitors (MSCs) using liquid metal current collectors on an elastic polymer substrate.

The team used eutectic gallium-indium (EGaIn), a liquid metal alloy, as the current collector since a deformable current collector is needed in order to create a deformable MSC. Commonly used current collectors made of brittle materials like gold (Au) are not suitable in this case, so the team turned to 'liquid metal' that inherently possesses the properties of a liquid and metallic conductivity.

Lyten announces manufacturing milestone - producing Lithium-sulfur batteries at greater than 90% yield

Lyten recently announced it is consistently surpassing 90 percent yield from its automated battery production line, confirming the manufacturability of its lithium-sulfur battery utilizing a sulfur cathode and lithium metal anode.

The lithium-sulfur manufacturing performance has been achieved utilizing standard lithium-ion manufacturing equipment and processes. The conversion of lithium-ion equipment to produce lithium-sulfur batteries in Lyten’s pilot facility required 6 weeks and less than 2% of the total capital cost. This confirms Lyten’s ability to rapidly scale by converting existing Li-ion gigafactories to lithium-sulfur with minimal cost and time.

Versarien signs South American Graphinks agreements with Montana Química

Versarien has announced that it has, in line with its stated strategy to monetize intellectual property through licensing, entered into a manufacturing license agreement and a know-how license and technical assistance agreement with Montana Química ("Montana"). Montana is a Brazilian headquartered multinational business focused on the production and sale of paints, wood preservatives and other wood finishing products including stains and varnishes. The agreements cover the use of the Company's proprietary graphene and related material dispersions and formulations (Graphinks™) in products to be manufactured and sold by Montana in South America, together with Versarien providing further additional know-how, technical assistance and training to Montana.

Under the terms of these agreements, Versarien has granted a license to Montana, for an initial period of five years, to use certain intellectual property and know-how owned by the Company in their business in South America. Montana will pay Versarien initial fees of £50,000 in March 2024 in consideration of the know-how and technical assistance, including training, to be provided. Once Montana commences manufacturing under the agreement, a further payment of £25,000 will be due to the Company, together with an amount equal to 5% of the total sales revenue earned from products manufactured using Versarien's intellectual property and know-how, subject to minimum royalty payments of £25,000 per annum.

Archer Materials miniaturizes biochip gFET chip design

Archer Materials has designed a miniaturized version of its Biochip graphene field effect transistor ("gFET") chip for fabrication at a commercial foundry.

The Archer Biochip contains a sensing region of which the gFET is the core component. Each gFET chip contains multiple gFETs, each of which is a transistor, which acts as a sensor. Archer has miniaturized the total chip size by redesigning the layout of the circuits creating these gFET transistors. The new miniaturized design has been sent to a foundry partner for a whole-wafer fabrication of reduced size gFET chips, which Archer intends to integrate with other parts of the Biochip technology.
