Graphenemex and the Future of Energy Storage:
Scientific Evidence from the Autonomous University of Chihuahua
The development of advanced materials for energy storage has become a global priority. More efficient batteries, long-lasting supercapacitors, and flexible electronic devices require materials capable of conducting electricity, withstanding electrochemical cycles, and maintaining structural stability at the nanoscale.
In this context, various investigations led by Dr. Claudia Georgina Nava-Dino from the Autonomous University of Chihuahua (UACH), in collaboration with CIMAV and other national research centers, have evaluated the performance of Graphenemex® exfoliated graphene and graphene oxide (GO) in applications related to energy storage systems and advanced electrochemistry.
In general terms, these nanomaterials have demonstrated important properties for such systems due to their combination of:
- high surface area,
- electrical conductivity,
- electrochemical stability,
- nanometric lamellar structure,
- ability to interact with lithium, titanates, and metal alloys,
- and favorable behavior under mechanical milling processes and electrochemical cycles.
Below is a timeline of research led by Dr. Claudia Nava-Dino, where the potential of Graphenemex® exfoliated graphene and graphene oxide for applications related to batteries, supercapacitors, and advanced energy storage has been studied.
2018 — Digital Signal Analysis of Electrochemical Signals of Graphene Oxides for Display Devices.
The work published in Cambridge University Press in 2018 explored the electrochemical behavior of GO combined with lithium titanate oxide through high-energy mechanical milling, observing that the material could maintain distinguishable and structurally stable electrochemical signals even under current and potential perturbation analysis.
For the research, in addition to graphenic materials, electrochemical analysis techniques and digital signal processing were used to study their stability and response under complex electrochemical conditions.
“Lithium titanate is one of the most promising materials for fast-charging batteries, long-life systems, and safe electrochemical storage. Therefore, the incorporation of a graphenic material in this type of system seeks to improve conductivity, stabilize interfaces, and facilitate electron transfer between active particles.”
One of the most important findings was that the electrochemical signals obtained from the material could be analyzed and stabilized using FFT (Fast Fourier Transform), allowing the identification of information that is normally not visible in conventional analysis. That is, the GO demonstrated good electrochemical stability, reproducible electrical responses, and a favorable interaction with lithium-based active materials.
GO with a stable nanometric structure.
This study also reported TEM images showing the characteristic hexagonal flakes of a well-exfoliated material. Which is relevant for fast electron transfer, electrical conduction between particles, and the reduction of internal resistances in electrodes, which in real applications translates into more efficient batteries, lower energy loss, and more stable electrodes during charge and discharge cycles.
Flexible electronics and portable devices .
Another relevant aspect of the 2018 work was the evaluation of electrochemical stability against mechanical deformations such as bending and twisting in portable electronic devices, which is especially relevant because many conductive materials lose connectivity when mechanically deformed. Pleasantly, the GO used presented good structural integrity and conductive connectivity even in mechanically demanding configurations. Identifying potential for the development of conductive screens, flexible devices, OLEDs, touch screens, and portable electronics.
2023 – Within the framework of the International Materials Congress, held in Cancun, Quintana Roo, the work “Benefits of Exfoliated Graphene on Lithium Titanate by Ball Milling” was presented, in which the compatibility of Graphenemex® exfoliated graphene with lithium titanate was evaluated ; the study was carried out in Li/Na systems using high-energy mechanical alloying, observing benefits associated with milling time and the structural interaction between graphene and the active storage phases.
2024 — Graphene-reduced Mg-Ni electrode for energy storage by mechanical alloying.
During the Congress of the Mexican Electrochemical Society (SMEQ), held in the City of Campeche, Camp., the research group presented new results related to graphene-reduced Mg-Ni electrodes for energy storage. In this work, the GO was incorporated through mechanical alloying at different milling times, followed by thermal treatments and electrochemical polarization and voltammetry tests.
In practical terms, the result was that the graphenic material helped maintain stability during repeated charge and discharge processes, one of the most important properties in supercapacitors, hybrid batteries, and advanced electrodes.
Compatibility with high-energy processes
The investigations also showed that graphenic materials possess sufficient structural stability to withstand intense mechanical impacts, energetic mixing, thermal treatments, and subsequent electrochemical processes without completely losing their functional properties, and consequently can be integrated into severe manufacturing processes such as:
- high-energy mechanical milling,
- thermal treatments,
- mixing with metal salts,
- and advanced electrochemical synthesis.
This is important because many nanomaterials lose structural functionality during these processes. However, the reported results indicate that the materials used retained relevant functional properties even after processing.
What capabilities do these graphenic materials show?
The research developed by the Autonomous University of Chihuahua, CIMAV, and collaborators, under the direction of Dr. Claudia Nava-Dino since 2018, has provided relevant scientific evidence regarding the potential of Graphenemex® exfoliated graphene and graphene oxide in energy storage technologies, as they have consistently demonstrated improvements in electrochemical stability, electronic conduction, and cyclic performance.
Today, more recent studies help to scientifically explain why this behavior occurs. An example is the article published by V. Bracamonte et al., in Batteries & Supercaps, 2026, where it is demonstrated that exfoliated graphene (Graphenemex®) offers a structural balance between electrical conductivity, controlled defects, and layer separation, favoring the mobility of lithium ions within the material.
These observations directly coincide with the results reported by C. Nava-Dino, reinforcing the potential of Graphenemex® graphenic materials for future applications in batteries, supercapacitors, and advanced energy storage devices. Beyond conventional applications, the studies also open up possibilities for integrating these nanomaterials into flexible electronics, smart devices, and advanced portable energy systems.
