Vanessa Peterson’s path from cement chemistry to battery research was not about turning cement into batteries. It was about learning how to reveal a material’s atomic structure—and how that structure affects what the material can do. The “Wombat” in this story is ANSTO’s neutron powder diffractometer, an instrument Peterson used in research spanning cement and energy materials.
How cement research led to a new set of materials questions
In a 2018 Chemistry World profile, Peterson describes beginning with a PhD focused on cement chemistry and structure. She was dissatisfied with an approximate model of cement’s structure and wanted a better account of what was happening inside the material. “When I started to look at cement structure with powder diffraction, I learned two things: that our current description of it was incorrect, and how complicated it was.”
Working with neutron specialist Brett Hunter, Peterson examined cement powders using neutron powder diffraction alongside laboratory X-ray diffraction and synchrotron X-ray diffraction. These are distinct measurement approaches; the profile describes them as complementary methods used to investigate structure, not interchangeable tools with a single universal ranking. The broader scientific idea is that a material’s atomic arrangement is connected to its properties and function. Peterson says the experience taught her “how important it is to find the right methods and expertise.”
What the Wombat instrument does
Wombat is a high-intensity neutron powder diffractometer at the Australian Nuclear Science and Technology Organisation (ANSTO). It is a scientific instrument, not an animal. ANSTO names several of its large instruments after Australian fauna.
#1 Best Overall
Neutron powder diffraction measures patterns produced when neutrons interact with a powdered material. Researchers use those patterns to determine and investigate atomic-scale structure. The Chemistry World profile describes Wombat as enabling fast measurements and real-time observation of structures at atomic resolution. Peterson compared the speed with earlier measurements by saying that a diffraction pattern that once took a week could be obtained in seconds. That is her comparison as reported in the 2018 profile, not an independent current performance test.
The profile also records Peterson saying Wombat was the fastest instrument of its kind when it was installed. That is a historical claim made in 2018, not a verified ranking for 2026. She joked: “We tend not to think of wombats as particularly fast, but they can outrun Usain Bolt”.
From structural measurements to battery research
After cement, Peterson’s work described in the profile turned to functional energy materials. Neutron powder diffraction let researchers investigate how electrode structures changed during charge and discharge—conditions in which the material is not simply sitting in a stable, unchanging state. Observing those structural changes can help scientists understand how an electrode behaves and what mechanisms may be involved.
The profile also describes research on prototype sodium-ion battery electrodes, compared with lithium-ion counterparts. The comparison concerned electrode materials and their structural behavior, not consumer battery life, price, safety, or commercial superiority. These were research questions about how materials function, not evidence that the prototypes were ready for sale.
What the cement-and-battery connection does—and does not—mean
The connection is Peterson’s materials-science career and the use of structural measurement to understand different materials. Cement was the subject of her doctoral work; battery electrodes became part of her later research. The 2018 profile does not report that cement was converted into batteries or that its cement work produced a commercial energy-storage product.
Cement-based energy storage is a separate area of research. A later review describes it as an emerging field with performance and scalability challenges. A 2025 paper on carbon-cement supercapacitors is another distinct development; neither should be confused with Peterson’s neutron-diffraction studies of battery electrodes.

Wombat represents a practical link between a question about a material and evidence about its structure. In Peterson’s account, the difficult cement problem called for suitable measurement methods and expertise; later, neutron diffraction offered a way to study energy materials as their structures changed during operation. The instrument did not make the scientific questions disappear—it gave researchers a way to observe and investigate them.
