Breakthrough in Battery Technology Promises Improved Energy Retention and Durability

KRKorea|

Researchers from Pohang University of Science and Technology in South Korea announced a significant advancement in lithium-ion battery technology that could enhance energy retention and durability. According to a lab summary by Tech Xplore, this breakthrough involves the use of lithium-rich layered oxide as a cathode material, which has been shown to increase energy density by up to 20% compared to traditional nickel-based batteries.

The team focused on addressing the common issues of capacity fading and voltage decay that have hindered the commercial viability of these batteries. By modifying the electrolyte composition, they effectively reduced oxygen release at the cathode interface, which substantially improves battery performance. Their results indicate an 84.3% energy retention rate after 700 charge-discharge cycles, compared to just 37.1% for traditional versions after 300 cycles.

As innovations continue in battery technology, experts believe these findings could pave the way for cleaner, more efficient energy solutions for electric vehicles and renewable energy storage, according to Professor Jihyun Hong.

South Korea's Constitutional Court Removes President Yoon Suk Yeol Following Controversial Martial Law Declaration

South Korea's Constitutional Court unanimously ruled on April 4, 2025, to remove President Yoon Suk Yeol from office due to his controversial attempt to impose martial law, which lawmakers labeled a "grave betrayal." This decision follows Yoon's suspension in December 2023 after he ordered armed soldiers to occupy parliament and was subsequently arrested on insurrection charges. Acting court President Moon Hyung-bae emphasized the "serious negative impact" of Yoon's actions on civilian governance, stating that these actions constituted significant constitutional violations. Yoon's removal is immediate and will lead to new presidential elections within 60 days, with authorities expected to announce the electoral date soon. This ruling comes at a time of heightened political tension in South Korea, with widespread public fallout from Yoon's actions. Protests have erupted from both supporters and opponents of the president, indicating a deeply divided political landscape.

South Korean President Yoon Suk Yeol Impeached and Removed from Office

South Korea's President Yoon Suk Yeol has been officially removed from office following a ruling by the country’s constitutional court, which upheld an impeachment decision by parliament. Yoon's impeachment stemmed from his controversial declaration of martial law in December, which he argued was necessary to combat "anti-state" forces supportive of North Korea. The court's unanimous decision has raised significant concerns regarding the future of democracy in South Korea. Acting president Han Duck-soo will oversee the government until a new president is elected, with a vote expected within 60 days. This ruling has intensified existing societal divisions, as Yoon's supporters claim the impeachment proceedings were illegal, while recent polls show that 60% of South Koreans favor his removal. Demonstrations involving both supporters and opponents have occurred, although a heavy police presence limited access to the court area during the ruling. Yoon, the second South Korean president to be impeached after Park Geun-hye in 2017, also faces separate insurrection charges that could carry severe penalties.

South Korea Faces Unprecedented Wildfires, 27 Lives Lost

South Korea is grappling with its worst wildfire crisis on record, with at least 27 fatalities and extensive destruction reported in the southeastern province of North Gyeongsang. According to officials, the fires, exacerbated by dry conditions and strong winds, have burned over 36,000 hectares, displacing around 37,000 residents. The country's disaster chief, Lee Han-kyung, declared the event a stark reminder of the severe realities posed by climate change. The wildfires, originating in Uiseong county, have outpaced previous fire disasters, exceeding the 23,913 hectares scorched in the 2020 wildfire. Responding to the emergency, the military has deployed resources to support firefighting efforts, with over 9,000 personnel and approximately 120 helicopters mobilized. The situation remains critical, with several historical sites, including two UNESCO World Heritage locations, under threat. Experts attribute the rapid spread to a combination of extremely low rainfall and climate change, which has intensified the region's dry conditions. The Korea Meteorological Administration reported that last year was the hottest on record, further contributing to the wildfire risks faced by the country.
