The lifespan of lithium metal batteries has been significantly extended by researchers from the Korea Advanced Institute of Science and Technology (KAIST). A study published in Advanced Materials details the development of an eco-friendly protective layer, resulting in a 750 percent increase in the lifespan of lithium metal anodes. According to the research, water served as the only solvent during the manufacturing process, addressing both environmental concerns and battery performance challenges.

Groundbreaking Eco-Friendly Solution

The study was published in the journal Advanced Materials. Professor Il-Doo Kim from KAIST’s Department of Materials Science and Engineering, alongside Professor Jiyoung Lee from Ajou University, led the research. A protective layer using hollow nanofibres was created through an electrospinning process, relying on guar gum extracted from plants. The approach eliminates the need for toxic materials typically used in such technologies, according to reports.

This layer functions both physically and chemically, stabilising lithium-ion growth and suppressing dendrite formation. The hollow spaces within the fibres minimise random lithium accumulation on the metal surface. Reports indicate that this innovative design maintains 93.3% capacity even after 300 charge-discharge cycles.

Impact on Battery Technology

It has been stated that conventional protective coatings often involve expensive and environmentally harmful processes, with limited efficacy. In contrast, the KAIST method prioritises sustainability, as the biodegradable layer decomposes completely in soil within a month.

Speaking to several media outlets, Professor Kim explained that the dual-action mechanism of the protective layer allowed for improved control over reversible reactions between lithium metal and electrolytes. This, he emphasised, achieved a longer-lasting anode with reduced environmental impact.

As battery demand continues to grow, the team’s water-based, eco-conscious method is expected to contribute significantly to the development of next-generation energy storage systems. These findings mark an important step towards reducing the ecological footprint of battery production and disposal, as reported by experts

Tomb of Pharaoh Thutmose II Discovered After 100 Years in Egypt

The tomb of Thutmose II, an Egyptian pharaoh who ruled around 3,500 years ago, has been uncovered west of the Valley of the Kings. This discovery marks the first time in a century that the burial site of a pharaoh has been found, as confirmed by the Egyptian Ministry of Tourism and Antiquities. The tomb, though largely empty, provides crucial insights into ancient burial practices. Initial findings suggest that soon after his burial, flooding led to the removal of the grave goods, leaving the chamber void of artefacts and a mummy. Despite this, ceramics inscribed with his name were identified at the site, enabling archaeologists to verify the tomb’s ownership.

Identification and Historical Significance

According to a statement by the Egyptian Ministry of Tourism and Antiquities, the tomb was first located in October 2022. However, it was only in late 2024 and early 2025 that archaeologists, through analysis of pottery fragments, confirmed it belonged to Thutmose II. Egyptologist Piers Litherland from the University of Cambridge, who co-led the excavation team, stated in an interview with Live Science that a piece of pottery bearing a label indicating the presence of natron, a key embalming substance, confirmed that a burial originally took place within the tomb.

Possibility of a Second Burial Site

Litherland also mentioned that while the tomb itself was not looted, all its contents were removed after the flooding. The possibility of a second, undiscovered tomb where these objects may have been relocated is being considered. Some experts believe that a mummy found in a cache at Deir el-Bahari could belong to Thutmose II, but discrepancies regarding the estimated age at death cast doubt on this theory. Ongoing research continues to explore whether his remains and burial goods are preserved elsewhere, potentially offering more insights into Egypt’s royal burials

Strange Fast Radio Bursts Emerge from an Ancient Dead Galaxy, Baffling Scientists

A distant galaxy that ceased star formation billions of years ago has been found emitting unusual radio signals, a phenomenon that has left astronomers searching for answers. Observations have revealed fast radio bursts (FRBs) originating from the outskirts of this long-dead galaxy, challenging current understanding of how these cosmic events occur. Typically associated with young, star-forming galaxies, FRBs are believed to result from supernovae or other stellar explosions. The presence of such bursts in an inactive galaxy defies existing theories, prompting new investigations into their origins.

Findings from the Study

According to two research published in The Astrophysical Journal Letters on January 21, astronomers detected 22 FRBs between February and November 2024 using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope in British Columbia. The bursts were traced back to an 11 billion-year-old galaxy that no longer forms stars, making it an unlikely host for such signals. The discovery suggests that alternative mechanisms beyond conventional stellar activity may be responsible for FRBs.

Expert Analysis on the Unusual Signals

Speaking to Live Science, Tarraneh Eftekhari, astronomer at Northwestern University and co-author of the study, stated that only about a hundred FRBs have been accurately linked to their host galaxies, with most originating from regions of active star formation. The new findings challenge previous assumptions, indicating that other, yet unknown, processes could be generating these bursts.

Vishwangi Shah, an astronomer at McGill University and a study co-author, highlighted the rarity of the event, noting that FRBs are typically detected near the centers of galaxies. The location of this burst in the galaxy’s outskirts makes it a unique anomaly in FRB research.

Possible Explanations and Future Research

While the exact cause of the radio bursts remains uncertain, scientists have proposed several possibilities. One hypothesis suggests that a collision between two aged stars could have triggered the bursts. Another theory points to a white dwarf collapsing under its own gravity. Further research and additional observations will be necessary to determine the precise cause of these signals.

With CHIME set to expand its capabilities in the coming months, researchers hope to identify more FRBs and their sources, potentially uncovering new insights into these mysterious cosmic phenomena.
