Patent number: 11456447Abstract: A predoping method for a negative electrode active material to dope the negative electrode active material with lithium ions. The predoping method for a negative electrode active material includes: a predoping process and a post-doping modification process. In the predoping process, the negative electrode active material is doped with lithium ions, to thereby reduce a potential of the negative electrode active material relative to lithium metal. In the post-doping modification process, after the predoping process, reaction is caused between a reactive compound that is reactive with lithium ions and lithium ions doped into the negative electrode active material, to thereby increase the potential of the negative electrode active material relative to lithium metal. The potential of the negative electrode active material relative to lithium metal is 0.8 V or more at completion of the post-doping modification process.Type: GrantFiled: February 21, 2019Date of Patent: September 27, 2022Assignees: NISSAN MOTOR CO., LTD., JSR CorporationInventors: Shotaro Doi, Yuki Kusachi, Noboru Yamauchi, Tomohiro Kaburagi, Hideaki Horie, Yusuke Nakashima, Kazuya Tsuchida, Naofumi Shoji, Koji Sumiya, Shigehito Asano, Yasuyuki Koga, Nobuo Ando, Terukazu Kokubo
