A research team at the Korea Research Institute of Chemical Technology (KRICT) has developed a new cathode technology that could help batteries store more energy without increasing their size or weight, the institute said Monday. The team, led by senior researchers Moon San and Suk Jung-don, developed a new dry thick cathode technology that improves the movement of lithium ions inside electrodes. The research was featured as the cover article of the international academic journal Exploration in August, with post-master's researcher Eun Hye-ji as the first author. The technology uses graphitic carbon nitride as an additive in dry cathodes for the first time, helping the electrolyte penetrate deeper into the electrode and reducing the energy required for lithium ions to enter the cathode material. One way to produce high-energy-density batteries is to make electrodes thicker, as this allows more active material to be packed into the same area. However, as electrodes become thicker, lithium ions have more difficulty moving through them, preventing the battery from fully utilizing the energ

State-run Korea Electric Power Corp. (KEPCO) said Monday it will keep electricity rates unchanged in the fourth quarter despite higher raw material prices and its financial difficulties. The adjusted fuel cost, a key component of electricity rates, will remain at the maximum level of 5 won per kilowatt-hour (kWh) for the October-December period, KEPCO said. KEPCO has kept the adjusted fuel cost at 5 won per kWh for 18 consecutive quarters since the third quarter of 2022. The adjusted fuel cost is set before each quarter within a range of plus or minus 5 won per kWh, based on energy prices, including coal and liquefied natural gas (LNG), over the previous three months. KEPCO said rates were due to rise by 7.3 won per kWh in the fourth quarter under the fuel cost adjustment formula. The decision to freeze rates is expected to further weigh on the company's finances. The company's financial difficulties began after it continued to supply electricity at prices below production costs as global energy prices surged between 2021 and 2023 following Russia's invasion of Ukraine.

In a breakthrough that could power the future of underwater operations, Chinese scientists have built and tested the world’s first submarine solar farm, successfully operating a perovskite-based photovoltaic system at a depth of 10 metres (33 feet) in the open sea. The submerged array charged batteries and powered a LED panel, proving that solar energy can be harvested even in the dim, blue-green twilight of the ocean. The achievement by a team from Yunnan University, published on September 11,...

Hong Kong authorities have captured three stray mongrels near a road in Yuen Long after a female cyclist was suspected of having died in a fatal dog attack in the area. The Agriculture, Fisheries and Conservation Department (AFCD) said on Monday that it had worked alongside police to capture three stray dogs near Pok Wai South Road on Sunday evening. But the AFCD sidestepped a question on whether some of the recent suspected attacks in the New Territories were linked to land resumption...

When Chinese artificial intelligence developers want to train their next-generation frontier models, they all face the same daunting wall: they cannot legally buy the world’s most powerful AI chips. However, the country’s tech giants and start-ups have still managed to quietly keep pace with global rivals. Their secret is an elusive workaround: moving heavy training workloads across borders through the cloud. By setting up proxy entities in foreign jurisdictions, domestic firms have for years...
