G3 and Lanka Graphite enter agreement to develop graphene-enhanced products

Apr 19, 2017

Global Graphene Group (G3), a holding company for subsidiaries like Angstron Materials, has signed Heads of Agreement with Lanka Graphite, a graphite exploration company. The joint venture entity (LGR 50%, G3 50%) will develop a range of commercial graphene projects.

G3 is reportedly scaling a broad range of commercial platforms of graphene applications in several , areas like energy storage, coatings, and thermal management. Lanka Graphite will supply vein graphite product into the joint venture in addition to assisting with sourcing investment, marketing and administration. G3 proposes to supply its experience in developing IP and research grants, commercialization planning and manufacturing infrastructure.

A new graphene oxide coating to improve the performance of lithium-sulfur batteries

Mar 21, 2017

Researchers at Yale University have developed an ultra-thin coating material, based on graphene oxide, that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries. The newly developed material is a dendrimer-graphene oxide composite film, that can be applied to any sulfur cathode.

The researchers state that sulfur cathodes coated with the material can be stably discharged and recharged for more than 1,000 cycles, enhancing the battery’s efficiency and number of cycles. In addition, they said “the developed film is so thin and light it will not affect the overall size or weight of the battery, and thus it will function without compromising the energy and power density of the device”.

Grafoid unveils GPURE graphene membrane for Li-ion batteries

Mar 15, 2017

Grafoid logoGrafoid, the Canadian graphene R&D, investment and technology company, announced the development of its GPURE Graphene Polymer nano-porous membrane intended for next generation Li-Ion battery applications.

The GPURE graphene polymer membrane (GPM) was developed as a chemically inert, freestanding membrane using graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi permeable membrane in a Li-ion battery structure. By protecting the sensitive electrode materials from unwanted chemical species GPURE GPM diffuses only energy harvesting monovalent ions such as Li+, Na+ etc.

China's Chowei Power announces graphene-enhanced lead-acid battery

Mar 09, 2017

Update: Our sources in china say that it is highly unlikely that this battery actually has any graphene materials in it...

Chinese battery manufacturer Chaowei Power launched a new version of its Black Gold battery — a lead-acid battery that reportedly uses graphene as an additive. The company states that the battery resistance is reduced by 52% and that performance of the battery in low temperature operations has been greatly improved.

Chowei's graphene batteries

Chaowei makes lithium and lead acid automotive batteries under the Chilwee brand. Its Black Gold high-energy VRLA series was launched in February 29, 2016, when it reportedly first applied graphene technology to a commercial, mass-produced rechargeable lead battery.
