Solidion plans to expand production capacity of silicon-rich graphene composite materials

Solidion Technology, an advanced battery technology solutions provider, has announced its plan to begin expanding the production capacity of silicon-rich graphene composite materials in early 2025.

The amount of energy that a lithium-ion battery can supply to an electric vehicle (EV) is limited by the amount of charges stored in its anode and cathode materials. Although graphite has been the preferred anode material during the past 30 years, silicon oxide (SiOx) and silicon (Si) are two evolving anode materials capable of improving the energy density of EV batteries and extending the EV range by 20-40%. However, the higher-capacity gain of both silicon and silicon oxide is limited by the technical issue of large volume change-induced rapid capacity decay and processing difficulty. Solidion has targeted this technical obstacle and has established a Dayton, Ohio-based facility for manufacturing silicon oxide (SiOx) and silicon (Si). The Solidion team is ready to expand the production capacity for these two types of high-capacity anode materials.

Researchers show that trilayer graphene with a twist could speed up electrochemical reactions

Researchers from the University of Michigan, SLAC National Accelerator Laboratory, Carnegie Mellon University and Harvard University have shown that three layers of graphene, in a twisted stack, benefit from a similar high conductivity to "magic angle" bilayer graphene but with easier manufacturing—and faster electron transfer. The findings could improve nano electrochemical devices or electrocatalysts to advance energy storage or conversion.

Twisting two sheets of graphene at a 1.1° angle, dubbed the "magic angle," creates a "flat band" structure, meaning the electrons across a range of momentum values all have roughly the same energy. Because of this, there is a huge peak in the density of states, or the available energy levels for electrons to occupy, at the energy level of the flat band which enhances electrical conductivity. Recent work experimentally confirmed these flat bands can be harnessed to increase the charge transfer reactivity of twisted bilayer graphene when paired with an appropriate redox couple—a paired set of chemicals often used in energy storage to shuttle electrons between battery electrodes. Adding an additional layer of graphene to make twisted trilayer graphene yielded a faster electron transfer compared to bilayer graphene, according to the team's recent study, that created an electrochemical activity model.

Researchers develop graphene membranes with pyridinic-nitrogen at pore edges or high-performance CO2 capture

Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have developed advanced graphene membranes with pyridinic-nitrogen at pore edges, reportedly showing unprecedented performance in CO2 capture. This could mark a step towards more efficient carbon capture technologies.

Carbon capture, utilization, and storage (CCUS) is a technology that reduces carbon dioxide (CO2) emissions from hard-to-abate industrial sources such as power plants, cement factories, steel mills, and waste incinerators. But current capture methods rely on energy-intensive processes, which makes them costly and unsustainable. Researchers are working to develop membranes that can selectively capture CO2 with high efficiency, thereby reducing the energy and financial costs associated with CCUS. But even state-of-the-art membranes, such as polymer thin films, are limited in terms of CO2 permeance and selectivity, which limits their scalability. So, the challenge is to create membranes that can simultaneously offer high CO2 permeance and selectivity, crucial for effective carbon capture.

Chinese researchers discover naturally occurring few-layer graphene in the Chang’e-5 lunar samples for the first time

Chinese researchers have reportedly discovered naturally occurring few-layer graphene in the lunar samples brought back by the Chang’e-5 probe, which provides new insights into the moon’s geological activities, evolutionary history, and environmental characteristics, broadening understanding of the complex mineral composition of lunar soil and offering information on resource utilization on the moon.

According to the research team from Jilin University, it is estimated that approximately 1.9 percent of the total interstellar carbon exists in the form of graphene, whose morphology and properties are determined by a specific formation process. Therefore, natural graphene can provide important reference and information for the geological evolution of celestial bodies and the in-situ resource utilization on the moon.
