中國研究人員開發出具有驚人彈性的彈性鋰硫電池組

這項創新是由中國電子科技大學的專家及其同事宣布的。

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.

中國電池研究人員開發出一種鋰硫電池組，由於採用了獨特的陰極塗層，具有驚人的彈性，ACS Publications 週四發布的實驗室摘要對此進行了詳細介紹。

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.

這項創新是由中國電子科技大學的專家及其同事宣布的。一款原型機在 300 次充電/放電循環後仍保持穩定。根據 ACS，另一種材料在被切成兩半或折疊後可以提供驚人的電力。

"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.

「由於其獨特的設計，電池在切割後仍能繼續發揮作用，即使在物理損壞後，導電網絡仍保持完整，」王立平教授告訴 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.

鋰硫電池使用常見材料，可能比鋰離子電池便宜。據 ACS 和 AZoNano 稱，這些電池組可以儲存大量電力。澳洲阿德萊德大學的專家表示，一些鋰硫電池已經為一些筆記型電腦、手機和其他設備供電。然而，阿德萊德的專家指出，這種類型的電池目前可能需要幾個小時才能充電。他們也致力於更好的鋰硫技術。

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.

根據總結，在中國，該團隊正在使用改進的硫化鐵陰極，在電極和電解質之間有一個特殊的層，以減少腐蝕並保持性能。當電池工作時，離子在稱為電解質的物質中在陽極和陰極之間移動。

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.

王的團隊在陰極上塗上聚丙烯酸，這使得電極能夠在數百次循環中保持放電能力。專家使用帶有碳酸鹽基電解質的塗層陰極、鋰箔和石墨基陽極製造了軟包電池和紐扣電池。

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

軟包電池在折疊或切割後即可工作。硬幣組在運行 300 次循環後仍保留 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.

這項突破可能為電動車和設備帶來更安全的電池。雖然電池起火的情況很少見，但它可能會造成災難性的後果，常常成為頭條新聞。但是，根據《波士頓環球報》報道，事實上，燃油汽車比電池驅動的汽車更容易燃燒。

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.

無論如何，提高安全性只能消除火災恐懼，有助於擴大我們技術的電氣化，以限制吸熱空氣污染。透過改用電動車甚至電磁爐來減少空氣污染可以為空氣和你的錢包帶來改變。作為參考，美國太空總署將全球暖化的煙霧與惡劣天氣風險的增加聯繫起來。將燃氣燃燒器停放在電動車上可以為您每年節省高達 1,500 美元的燃氣和維護費用。除此之外，您還可以享受數千美元的稅收減免，以幫助您購買一輛車。

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

在中國，Li-S 的最新發現可能是使其成為主流的又一步。

"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 的團隊表示：“總的來說，結果表明，塗層陰極不僅可以生產出更安全、壽命長的鋰硫電池，而且還可以生產出含有其他金屬硫化物的高效電池。”
