中国研究人员开发出具有惊人弹性的弹性锂硫电池组

这项创新是由中国电子科技大学的专家及其同事宣布的。

Chinese battery researchers have developed a lithium-sulfur pack with amazing resilience thanks to a unique cathode coating, as detailed in a lab summary published by ACS Publications on Thursday.

中国电池研究人员开发出一种锂硫电池组，由于采用了独特的阴极涂层，具有惊人的弹性，ACS Publications 周四发布的实验室摘要对此进行了详细介绍。

The innovation was announced by experts from the University of Electronic Science and Technology of China and colleagues. One prototype remained stable after 300 charge/discharge cycles. Another one can astoundingly provide power after being cut in half or folded, per ACS.

这项创新是由中国电子科技大学的专家及其同事宣布的。一款原型机在 300 次充电/放电循环后仍保持稳定。根据 ACS，另一种材料在被切成两半或折叠后可以提供惊人的电力。

"The battery continues to function after being cut due to its unique design, where the conductive network remains intact even after physical damage," Professor Liping Wang told Interesting Engineering.

“由于其独特的设计，电池在切割后仍能继续发挥作用，即使在物理损坏后，导电网络仍保持完整，”王立平教授告诉 Interesting Engineering。

Lithium-sulfur, or Li-S, batteries use common materials and could be cheaper than lithium-ion alternatives. The packs can store a lot of power, according to ACS and AZoNano. Some Li-S batteries already energize some laptops, phones, and other devices, according to experts at the University of Adelaide in Australia. However, those Adelaide experts note that this type of battery can currently take hours to charge. They are working on better Li-S tech, as well.

锂硫电池使用常见材料，可能比锂离子电池更便宜。据 ACS 和 AZoNano 称，这些电池组可以储存大量电力。澳大利亚阿德莱德大学的专家表示，一些锂硫电池已经为一些笔记本电脑、手机和其他设备供电。然而，阿德莱德的专家指出，这种类型的电池目前可能需要几个小时才能充电。他们也在致力于更好的锂硫技术。

In China, the team is using an improved iron sulfide cathode with a special layer between the electrode and electrolyte to reduce corrosion and maintain performance, according to the summary. When a battery operates, ions move between the anode and cathode in a substance called electrolyte.

根据总结，在中国，该团队正在使用改进的硫化铁阴极，在电极和电解质之间有一个特殊的层，以减少腐蚀并保持性能。当电池工作时，离子在称为电解质的物质中在阳极和阴极之间移动。

Wang's team coated the cathodes with polyacrylic acid, which retained the electrode's ability to discharge power for hundreds of cycles. The experts built both a pouch cell and a coin cell battery using a coated cathode with a carbonate-based electrolyte, lithium foil, and a graphite-based anode.

王的团队在阴极上涂上聚丙烯酸，这使得电极能够在数百次循环中保持放电能力。专家们使用带有碳酸盐基电解质的涂层阴极、锂箔和石墨基阳极制造了软包电池和纽扣电池。

The pouch cell worked after being folded or cut. The coin pack retained 72 percent of its capacity after running for 300 cycles.

软包电池在折叠或切割后即可工作。硬币组在运行 300 次循环后仍保留 72% 的容量。

The breakthrough could lead to a safer battery for electric vehicles and devices. While rare, battery fires can be catastrophic, often making headlines. But, as reported by the Boston Globe, gas cars are, in fact, more likely to combust than battery-powered ones.

这一突破可能会为电动汽车和设备带来更安全的电池。虽然电池起火的情况很少见，但它可能会造成灾难性的后果，常常成为头条新闻。但是，据《波士顿环球报》报道，事实上，燃油汽车比电池驱动的汽车更容易燃烧。

Regardless, improving safety can only extinguish fire fears, helping to expand the electrification of our tech to limit heat-trapping air pollution. Cutting air pollution by switching to an EV or even an induction cooktop can make a difference for the air and your pocketbook. NASA, for reference, links planet-warming fumes to an increased risk of severe weather. And parking your gas-burner in favor of an EV can save you up to $1,500 a year in gas and maintenance costs. That's on top of thousands of dollars in tax breaks that are available to help you buy one.

无论如何，提高安全性只能消除火灾恐惧，有助于扩大我们技术的电气化，以限制吸热空气污染。通过改用电动汽车甚至电磁炉来减少空气污染可以为空气和你的钱包带来改变。作为参考，美国宇航局将全球变暖的烟雾与恶劣天气风险的增加联系起来。将燃气燃烧器停放在电动汽车上可以为您每年节省高达 1,500 美元的燃气和维护费用。除此之外，您还可以享受数千美元的税收减免，以帮助您购买一辆车。

In China, the latest Li-S findings could be another step toward making them more mainstream.

在中国，Li-S 的最新发现可能是使其成为主流的又一步。

"Overall, the results indicate that coated cathodes could produce not only safer Li-S batteries with long lifespans, but also efficient batteries with other metal sulfides," according to Wang's team, per ACS.

Wang 的团队表示：“总的来说，结果表明，涂​​层阴极不仅可以生产出更安全、寿命长的锂硫电池，而且还可以生产出含有其他金属硫化物的高效电池。”
