Putin insists Ukraine's new US-supplied weapon won't change the war's outcome_我的网站

A |     KYIV, Ukraine -- A Russian missile attack killed two civilians in an apartment building in southern Ukraine on Wednesday, local authorities said, as President Vladimir Putin dismissed the importance of a new U.S.-supplied weapon that Kyiv used to execute one of the most damaging attacks on the Kremlin’s air assets since the start of the war.Putin told reporters that Russia “will be able to repel” further attacks by the U.S.-made Army Tactical Missile System, known as ATACMS.Ukraine claimed it used those missiles to destroy nine Russian helicopters, as well as ammunition, an air defense system and other assets at two airfields in Russia-occupied regions on Tuesday.That development came as the two sides looked to gain battlefield advantages and consolidate their positions ahead of the winter when the weather would hamper operations.The ATACMS will shift the battlefield layout to some degree as Russia will need to disperse its aircraft and ammunition depots. It had used aircraft to stop Ukraine’s ongoing counteroffensive.Putin, speaking to reporters during a visit to Beijing, conceded the ATACMS creates an additional threat but he insisted that the weapon would not change the situation along the 1,500-kilometer (932-mile) front line.“For Ukraine, in this sense, there’s nothing good ... it only prolongs the agony,” he said.Russia’s ambassador to the U.S., Anatoly Antonov, described Washington’s decision to supply the ATACMS as “reckless” and “a grave mistake” that won’t alter the war’s outcome.The fighting has ground largely to a stalemate, with a protracted war of attrition expected at least through next year.The U.K. defense ministry said Wednesday that the Kremlin’s forces are currently trying to push forward in some parts of eastern Ukraine. However, the areas are well defended and it is “highly unlikely” the Russians will accomplish their goal of a major breakthrough, it said in an assessment posted on social media platform X, formerly known as Twitter.Wednesday's attack killed two Ukrainian civilians and wounded at least three others when a Russian missile struck a building in the central district of the southern city of Zaporizhzhia, the region’s Gov. Yurii Malashko said.The attack apparently used six S-300 missiles, which took only 42 seconds to reach the city after being launched from Russian-controlled Ukraine land, according to Malashko.Russia’s defense ministry, meanwhile, claimed its forces shot down 28 Ukrainian drones in the Belgorod and Kursk regions and in the Black Sea area. It did not provide further details.It wasn’t immediately possible to verify the two sides’ battlefield claims.___Jim Heintz in Tallinn, Estonia contributed.___Follow AP’s coverage of the war in Ukraine at https://apnews.com/hub/russia-ukraine。    

    Different types of consumer lithium primary batteries on display Photo: VCGChinese researchers have developed a new high-energy lithium primary battery that can deliver both long-lasting energy and strong bursts of power while maintaining stable performance at temperatures as low as -40 C, Science and Technology Daily reported on Monday.
A research team led by Chen Zhongwei at the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences developed a 25-ampere-hour pouch-type lithium-metal primary battery. Tests conducted by the safety laboratory of the China Electronics Standardization Institute showed that the battery achieved an energy density of more than 750 Watt-hour per kilogram at a low discharge rate, according to the report.
Meanwhile its discharge rate can be increased by up to 100 times, enabling short bursts of high-current discharge at 10C. The "C" stands for C-rate, which is the charge and discharge rates of a battery. According to sector website Battery University, the capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes. 
The new battery puts China among the world's leading players in high-power primary battery technology.
Primary batteries offer high specific energy, long storage times and instant readiness, allowing them to be used immediately even after long storage. 
Primaries play an important role, especially when charging is impractical or impossible, such as in military combat, rescue missions and forest-fire services, the article said. 
Traditional lithium primary batteries can store large amounts of energy for long periods, but their ability to rapidly release that energy can be limited. The new battery is designed to combine high energy density with high power output, allowing it to both operate for extended periods and provide large amounts of power when needed.
The battery can deliver short bursts of high-current discharge at up to 10C and sustain discharge at 4C. At room temperature, its specific power reaches 4,487 Watts per kilogram, according to Science and Technology Daily.
The battery also maintains strong performance under extremely cold conditions. At -40 C, the battery retains an energy density of 447 Watt-hour per kilogram at a 1C discharge rate. Its annual self-discharge rate is below 1 percent, meaning that it loses relatively little stored energy during long periods of standby.
Such characteristics could make the battery suitable for equipment that needs both long-term energy storage and sudden high-power output, including drones, robots, spacecraft and sensors deployed in remote areas.
Chen said the team achieved a breakthrough in cathode materials by developing a high-entropy oxide material and has established a pilot production line with an annual capacity of 10 tons, linking material development with battery-cell production.
The battery has passed third-party testing and is now undergoing further validation for applications including drones, robots, spaceflight simulators and field sensor nodes, according to Chen.
