中国团队柔性有机电池或改变可穿戴设备面貌

中国研究人员开发出一种创新有机正极材料,使电池在极端温度下高效稳定运行,从零下到80摄氏度。该材料解决了传统锂离子电池的成本和安全问题,并为可穿戴设备提供了潜在应用。研究由天津大学徐云华和华南理工大学黄飞领导,结果于2月18日发表于《自然》杂志。

中国研究人员在有机电池领域取得突破,该电池使用聚(苯并二呋喃二酮)(PBFDO)作为有机正极材料。这种材料能够在从零下到80摄氏度(176华氏度)的极端温度范围内实现高效和稳定的性能。

传统锂离子电池通常采用无机矿物如锂钴氧化物或磷酸铁锂作为正极材料,其生产成本取决于矿产资源可用性,并在碰撞或过热时存在安全风险。为了应对这些挑战,研究人员探索使用柔性有机材料作为替代品。这些材料本质上稳定,降低了燃烧或爆炸风险,并且更容易合成和回收。其抗弯曲性也使其成为可穿戴设备的理想候选者。

然而,有机材料通常电导率低,需要大量导电添加剂。小有机分子还容易在电解质中溶解,导致电池寿命缩短。根据《中国科学报》上周发布的报告,中国研究人员已迈出将有机电池从实验室带入实际应用的关键一步。

该研究由天津大学的徐云华和华南理工大学的黄飞领导。他们的发现于2月18日发表于《自然》杂志。这一进展可能推动有机电池从实验室走向现实应用,尤其在可穿戴电子设备领域。

Used batteries from electric vehicles could fulfill two-thirds of China's grid storage requirements by 2050, according to a study by researchers at Tsinghua University. These second-life batteries would charge during periods of abundant renewable energy and release power during peak demand. The approach could reduce costs by 2.5 percent while supporting a shift to carbon-neutral power systems.

Following the recent resumption of 4680 cell production for Model Y vehicles, Tesla has confirmed achieving a key manufacturing milestone: full dry-electrode processing for both anode and cathode components. VP Bonne Eggleston highlighted the breakthrough on X, enhancing supply chain resilience amid trade tensions, as noted in the Q4 and FY 2025 update.
