China, South Korea Drive EV Battery Innovation: Breakthroughs In Stability, Fire Safety
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).
中国大连化学物理研究所的研究人员在电池技术领域取得了重大突破,可能对新能源车的未来产生影响。
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.
由张长坤和李显方教授领导的团队,开发了新的基于萘的有机氧化还原活性分子(ORAMs)用于水性有机流动电池(AOFBs)。这些分子提供了前所未有的稳定性,显著延长了电池的寿命。
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.
实验结果显示,根据Interesting Engineering的报道,新电池在600次充放电循环中保持了99.95%的容量。而传统流动电池通常依赖昂贵的钒,通过与外部元素的副反应而发生降解 - 新的ORAMs使AOFBs更加耐用、具有成本效益,并更易于扩展。
Improving battery durability and stability has been crucial for EVs to replace fossil-fuel-powered vehicles, but China is already at the forefront.
提高电池的耐久性和稳定性对于新能源车取代燃油车辆至关重要,而中国已经走在了前列。
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.
今年早些时候,特斯拉的重要电池供应商CATL在北京国际汽车展览会上推出了神行Plus电池组。这款电池在10分钟充电后可提供370英里的行驶里程,在满电后可超过620英里,解决了行业对行驶里程焦虑的疑虑。
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.
除了行驶里程焦虑,火灾风险仍然是一个批评点。新能源车起火视频每月都会变得火爆,但韩国科技巨头LG正在研究解决方案。
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化学,韩国最大的化工公司,宣布通过“安全增强层”在新能源车火灾预防方面取得突破。这种薄的复合材料,放置于正极和电流集电体之间,通过防止热失控来阻止火灾。当温度超出安全范围时,该材料会在化学上中断电路,本质上成为电池内的自灭保险。
"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.
“这是一项切实可行的研究成果,可以在短时间内用于大规模生产,”首席技术官李钟株在新闻发布会上说。
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.
这种新材料显著降低了新能源车起火的几率,并可能为特斯拉-电池组的安全奠定基础。到2025年大规模测试结束时,如果成功,这一创新将解决消费者对新能源车的最重要担忧之一,进一步加速其普及。
Earlier this year, LG Chem signed a $19b deal with General Motors (NYSE:GM) to supply EV batteries through 2035.
今年早些时候,LG化学公司与通用汽车(纽交所:GM)签署了一项价值190亿美元的协议,将通过2035年供应新能源车电池。
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.
值得关注的ETF:Global X无人驾驶和电动汽车ETF(纳斯达克:DRIV)旨在投资于涉及新能源车及其元件和材料、自动驾驶车辆和硬件的公司。
