China, South Korea Drive EV Battery Innovation: Breakthroughs In Stability, Fire Safety
Improving battery durability and stability has been crucial for EVs to replace fossil-fuel-powered vehicles, but China is already at the forefront.Researchers at the Dalian Institute of Chemical Physics in China have achieved a major breakthrough in battery technology, which could potentially influence the future of electric vehicles (EVs).
中國大連化學物理研究所的研究人員在電池技術領域取得了重大突破，可能對新能源車的未來產生影響。
The team, led by professors Zhang Changkun and Li Xianfang, developed new naphthalene-based organic redox-active molecules (ORAMs) for aqueous organic flow batteries (AOFBs). These molecules provide unprecedented stability, significantly extending batteries' lifespan.
由張長坤和李顯方教授領導的團隊，開發了新的基於萘的有機氧化還原活性分子（ORAMs）用於水性有機流動電池（AOFBs）。這些分子提供了前所未有的穩定性，顯著延長了電池的壽命。
Lab results showed the new battery retained 99.95% of its capacity over 600 charge cycles, per Interesting Engineering's report. While traditional flow batteries often depend on costly vanadium and experience degradation through side reactions with external elements – new ORAMs make AOFBs more durable, cost-effective, and easier to scale.
實驗結果顯示，根據Interesting Engineering的報道，新電池在600次充放電循環中保持了99.95%的容量。而傳統流動電池通常依賴昂貴的釩，通過與外部元素的副反應而發生降解 - 新的ORAMs使AOFBs更加耐用、具有成本效益，並更易於擴展。
Improving battery durability and stability has been crucial for EVs to replace fossil-fuel-powered vehicles, but China is already at the forefront.
提高電池的耐久性和穩定性對於新能源車取代燃油車輛至關重要，而中國已經走在了前列。
Earlier this year, Tesla's key battery supplier, CATL, introduced the Shenxing Plus battery pack at the Auto China Show. This battery offers a 370-mile range on a 10-minute charge and over 620 miles on a full charge, addressing the industry's lingering concerns over range anxiety.
今年早些時候，特斯拉的重要電池供應商CATL在北京國際汽車展覽會上推出了神行Plus電池組。這款電池在10分鐘充電後可提供370英里的行駛里程，在滿電後可超過620英里，解決了行業對行駛里程焦慮的疑慮。
Besides range anxiety, fire risk remains a point of criticism. EV car fire videos go viral every month, but South Korean tech giant LG is working on a solution.
除了行駛里程焦慮，火災風險仍然是一個批評點。新能源車起火視頻每月都會變得火爆，但韓國科技巨頭LG正在研究解決方案。
Its subsidiary, LG Chem, the largest Korean chemical company, announced a breakthrough in EV fire prevention through a "Safety Reinforced Layer." This thin composite material, placed between the cathode and current collector, works to stop fires by preventing thermal runaway. The material chemically disrupts the circuit when temperatures exceed a safe range, essentially working as a self-extinguishing fuse within the battery.
其子公司LG化學，韓國最大的化工公司，宣佈通過「安全增強層」在新能源車火災預防方面取得突破。這種薄的複合材料，放置於正極和電流集電體之間，通過防止熱失控來阻止火災。當溫度超出安全範圍時，該材料會在化學上中斷電路，本質上成爲電池內的自滅保險。
"This is a tangible research achievement that can be applied to mass production in a short period of time," CTO Lee Jong-gu said in a press release.
「這是一項切實可行的研究成果，可以在短時間內用於大規模生產，」首席技術官李鍾株在新聞發佈會上說。
The new material dramatically reduces the chance of EV fires and could pave the way for safer battery packs by 2025 when large-scale testing concludes. If successful, this innovation will address one of consumers' most significant concerns about EVs, further accelerating adoption.
這種新材料顯著降低了新能源車起火的幾率，並可能爲特斯拉-電池組的安全奠定基礎。到2025年大規模測試結束時，如果成功，這一創新將解決消費者對新能源車的最重要擔憂之一，進一步加速其普及。
Earlier this year, LG Chem signed a $19b deal with General Motors (NYSE:GM) to supply EV batteries through 2035.
今年早些時候，LG化學公司與通用汽車（紐交所:GM）簽署了一項價值190億美元的協議，將通過2035年供應新能源車電池。
ETF to watch: Global X Autonomous & Electric Vehicles ETF (NASDAQ:DRIV) seeks to invest in companies involved with EVs and their components and materials, as well as autonomous vehicles and hardware.
值得關注的ETF：Global X無人駕駛和電動汽車ETF（納斯達克:DRIV）旨在投資於涉及新能源車及其元件和材料、自動駕駛車輛和硬件的公司。
