As the global transition to renewable energy intensifies, the search for high-performance batteries and efficient electrocatalysts has become a critical race against time. Traditionally, discovering these materials required years of "trial-and-error" laboratory experiments. Now, a comprehensive review published in the journal ENGINEERING Energy by researchers from Tongji University reveals how Artificial Intelligence (AI) is fundamentally shifting this paradigm.
The study, led by Professor Menghao Yang’s team at the Institute of New Energy for Vehicles, Tongji University, provides a systematic roadmap of the AI evolution in energy materials—tracing a complete technical pathway from classical Machine Learning (ML) to Representation methods, then to Discriminative tasks, followed by Generative tasks and Domain-integrated AI systems, and finally to Large Models.
Beyond Trial and Error: The Rise of "Inverse Design" One of the most transformative shifts highlighted in the research is the move toward "Inverse Design." Unlike traditional methods that test existing materials to find their properties, AI-driven generative models allow scientists to start with a desired performance goal (such as high energy density or specific catalytic activity) and work backward to predict the exact chemical structure required.
"The integration of AI into energy materials research is no longer just a trend; it is a necessity for efficiency," says Professor Yang. "By utilizing generative AI and Large Language Models, we can navigate the vast chemical space of potential materials at speeds that were previously unimaginable."
Batteries, Catalysts, and the Power of Large Models The review delves into two primary domains where AI is making the most significant impact:
Secondary Batteries: AI algorithms are now used to predict battery lifespan, optimize electrolyte compositions, and enhance the safety of Li-ion and next-generation battery systems.
Electrocatalysis: For critical reactions like the Hydrogen Evolution Reaction (HER) or Oxygen Reduction Reaction (ORR), AI helps identify optimal surface structures of catalysts, facilitating the production of green hydrogen and the reduction of CO2 emissions.
The researchers emphasize that the emergence of "Large Models" (including LLMs) is particularly exciting. These models can process vast amounts of unstructured scientific literature, extract hidden correlations, and even suggest new experimental synthesis routes, acting as an "intelligent co-pilot" for material scientists.
Future Horizons While the potential is vast, the team notes that challenges remain, particularly regarding the quality of experimental data and the "black box" nature of some AI models. The paper outlines a future where "Self-Driving Laboratories"—where AI designs, performs, and analyzes experiments autonomously—could become the standard for energy research.

A University of the Sunshine Coast study of young teenagers has identified a vicious cycle of loneliness linked to the fear of embarrassment or judgement by peers.
The study of more than 170 children aged 13 to 15 found that those staying under the radar socially to avoid judgement reported greater loneliness, as well as lower trust, connection and participation in friendships.
“It explored why some teens feel lonely even when surrounded by their peers, and identified the key pattern of social avoidance,” said ...
The Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) launched the MOH–NUS Postgraduate Fellowship in Biomedical Ethics, a postgraduate programme to advance the understanding and translation of the practice of ethics in healthcare settings, and to equip healthcare professionals and leaders with the frameworks and tools to address real-world ethical challenges in everyday healthcare practice. The first awardee of the Fellowship is Ms Kwek Shi Qi, a registered nurse at the National University Hospital (NUH), and alumna of the Alice Lee Centre for ...
Sungkyunkwan University (President: Jibeom Yoo) announced that a joint research team led by Professors Han-Ki Kim and Bo Ram Lee from the School of Advanced Materials Science and Engineering has developed a next-generation transparent electrode technology that completely eliminates the use of the rare metal indium, while maintaining high performance and significantly extending device lifetime.
Perovskite light-emitting diodes (PeLEDs), which have recently attracted considerable attention as a key technology for next-generation ...
Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum computers can solve complex equations at staggeringly fast speeds that vastly outpace regular computers. In real hardware, the operations of quantum computers often deviate from the ideal behavior because of device imperfections and unwanted noise from the environment. To build reliable quantum machines, researchers need a way to accurately determine what a quantum device is actually doing.

In a dry riverbed in Brazil, in a dense forest near the Amazon, a team of paleontologists found a fossilized jawbone from an ancient animal. Over the course of their fieldwork, they found eight similar bones, each around six inches long—but no other bones that they could confidently use to complete a skeleton for one of these mystery animals. However, the jawbones alone were enough to reveal that they belonged to a species that would have been a “living fossil” for its time, 275 million years ago when it lived. What’s more, the jawbones were oddly twisted, with some ...
Jackdaw chicks learn about predators by listening to adults, new research shows.
Scientists played recordings of predator calls to chicks in their nests – and paired the sounds with either adult jackdaw “alarm” calls or “contact” calls that indicate no danger.
Chicks that heard predator sounds paired with alarm calls learned to fear the predator – becoming more vigilant on hearing that sound again – while chicks that heard contact calls did not.
The study, by researchers at the University ...
The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.
An Adelaide University survey of more than 600 South Australians during the peak of the 2025 bloom found high levels of ‘eco-anxiety’ – distress linked to environmental damage – with many participants reporting persistent worry, sadness and feelings of helplessness.
The findings have recently been published in the Journal of Environmental ...
A research team led by Prof. Seunguk Song from the Department of Energy Science at Sungkyunkwan University (SKKU), in collaboration with the Institute for Basic Science (IBS), the University of Pennsylvania, and the U.S. Air Force Research Laboratory, has published a comprehensive technical roadmap for two-dimensional (2D) Indium Selenides (InSe)—a key material for next-generation low-power and quantum computing.
The study, titled “Indium selenides for next-generation electronics and optoelectronics,” was recently published in Nature Reviews Electrical Engineering, the ...
A new Cochrane review has found that sucrose can help with pain relief in newborn babies during common hospital procedures, such as venepuncture. This involves drawing blood with a needle, typically for testing.
Newborns, especially preterm infants in neonatal intensive care units (NICUs), undergo numerous painful procedures. Because of their immature pain regulation, they can experience these procedures intensely. Preventing and treating procedural pain in hospitalised newborns is important, as repeated untreated pain has been associated with poorer physical ...
