A team of scientists from the University of Manchester has gained new understanding of lithium-ion storage within the thinnest possible battery anode - composed of just two layers of carbon atoms. Their work shows an unexpected ‘in-plane staging’ process during lithium intercalation in bilayer graphene, which could pave the way for advancements in energy storage technologies.
Lithium-ion batteries, which power everything from smartphones and laptops to electric vehicles, store energy through a process known as ion intercalation. This involves lithium ions slipping between layers of graphite - a material traditionally used in battery anodes, when a battery is charged. The more lithium ions that can be inserted and later extracted, the more energy the battery can store and release. While this process is well-known, the microscopic details have remained unclear. The Manchester team’s discovery sheds new light on these processes by focusing on bilayer graphene, the smallest possible battery anode material.

Researchers at the National Graphene Institute and their collaborators have gained understanding into how electric field effects can selectively accelerate coupled electrochemical processes in graphene. Electrochemical processes are essential in renewable energy technologies like batteries, fuel cells, and electrolysers. However, their efficiency is often hindered by slow reactions and unwanted side effects. Traditional approaches have focused on new materials, yet significant challenges remain.
The Manchester team, led by Dr. Marcelo Lozada-Hidalgo, has taken a novel approach. They have successfully decoupled the inseparable link between charge and electric field within graphene electrodes, enabling unprecedented control over electrochemical processes in this material. The breakthrough challenges previous assumptions and opens new avenues for energy technologies.
Researchers from Pohang University of Science and Technology (POSTECH), Korea Institute of Industrial Technology and Konkuk University have reported the development of a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling.

Micro supercapacitors (MSCs) have emerged as a promising candidate for deformable energy storage, due to high-power density, rapid charging, and long cycle life. However, the fabrication of interdigitated electrode patterns capable of maintaining the energy storage performance under repeated stretching and twisting has remained a great challenge, because brittle materials like gold (Au) have been commonly used as an electrode.

University of Arkansas physics professor Paul Thibado received a commitment of $904,000 from the WoodNext Foundation, administered by the Greater Houston Community Foundation. The five-year grant will support Thibado’s development of graphene energy harvesters.
“We have successfully developed a process for building graphene energy harvesting device structures,” Thibado said, “but current structures do not harvest enough power. This proposal will allow us to optimize these structures to harvest nanowatts of power, which is enough energy to run sensors.”
Researchers from the University of Hyderabad (UoH) and the Tata Institute of Fundamental Research (TIFR) have developed electrode materials made of Tin antimony alloy based reduced graphene oxide composite which has the potential to enhance energy storage for sodium-ion batteries.
Sodium-ion batteries could offer enhanced energy efficiency, rapid charging capabilities, resilience to extreme temperatures, and safeguards against overheating or thermal runaway incidents. They exhibit reduced toxicity due to their lack of reliance on lithium, cobalt, copper, or nickel, which have the potential to emit environmentally harmful gases in the event of fire, according to a recent official release.
Researchers at Texas A&M University recently discovered that when charging a supercapacitor, it stores energy and responds by stretching and expanding. This insight could be help design new materials for flexible electronics or other devices that need to be both strong and store energy efficiently.
The team measured stresses that developed in graphene-based supercapacitor electrodes and correlated the stresses to how ions move in and out of the material. For example, when a capacitor is cycled, each electrode stores and releases ions that can cause it to swell and contract. According to the team, this repeated motion can cause the build-up of mechanical stresses, resulting in device failure. To combat this, the research looks to create an instrument that measures mechanical stresses and strains in energy storage materials as they charge and discharge.
