Core Viewpoint - The research team from Kyoto University and Toyota has developed a "full-solid-state fluoride ion battery" that significantly enhances energy capacity compared to traditional lithium-ion batteries, aiming for practical application in electric vehicles (EVs) after 2035 [1][2]. Group 1: Battery Technology Advancements - The new positive electrode material "copper nitride" allows each nitrogen atom to obtain three electrons, resulting in a volumetric capacity that is three times that of lithium-ion batteries and a weight capacity that is twice that [1]. - The anticipated volumetric energy density of the new battery is expected to exceed twice that of lithium-ion batteries, potentially increasing the range of electric vehicles from approximately 600 kilometers to around 1200 kilometers [2]. Group 2: Research Collaboration and Future Development - The research collaboration includes not only Kyoto University and Toyota but also Tokyo University, Hyogo Prefectural University, Tohoku University, and Tokyo University of Science, with findings published in the American Chemical Society journal [2]. - The development of the full-solid-state fluoride ion battery requires further advancements in the negative electrode and solid electrolyte, which the research team plans to pursue [2].

京都大学等机构研发的正极材料"氮化铜"能够使氮原子与氟化物离子反应，每个氮原子能提取三 个电子，因此其体积当量容量是锂离子电池的三倍，重量当量容量则为两倍。 1月26日，日本京都大学与丰田汽车等研究团队宣布，他们成功提升了全固态氟化物离子 电池 正 极的体积当量容量，使其达到锂离子电池的三倍以上。 这种新型电池的体积能量密度预计将是当前锂离子电池的两倍多，研究人员计划在2035年后将其 应用于电动汽车。 此外，该材料具有良好的耐久性，能够支持数十次充放电。如果成功应用该电极组装全固态氟化 物离子电池，预计其体积能量密度将是锂离子电池的两倍以上，这意味着电动汽车的续航里程有 望从当前的约600公里提升至1200公里左右。研究团队正着手进行负极和固体电解质的进一步开 发。 （ 来源：一电快讯 ） 圆柱电池巡访： ☆走进国轩高科 ☆走进利维能 ☆走进诺达智慧 ☆走进中泽科技 ☆走进苏州力神 ☆走进睿恩新能源 ☆走进天鹏电源 ☆走进中比新能 源 ☆走进天能集团 ☆走进新能安 ☆走进浙江锋锂 ☆走进华立源 ☆走进鹏辉能源 ☆走进欣旺达锂威 ☆走进深圳中基 ☆走进博力威 ☆走进恒泰科技 圆柱电池论坛： 行业首届圆柱电池技 ...
