ジャンポール・ガバノ(Jean-Paul Gabano)編,「リチウム・バッテリーズ(Lithium Batteries )」,ロンドン,ニューヨーク,アカデミック・プレス(Academic Press),1983年
図1は、第1の実施の形態に係る二次電池の断面構造を表すものである。この二次電池は、負極の容量が電極反応物質であるリチウムの析出および溶解による容量成分により表される、いわゆるリチウム金属二次電池である。この二次電池は、いわゆる円筒型といわれるものであり、ほぼ中空円柱状の電池缶11の内部に、帯状の正極21と帯状の負極22とがセパレータ23を介して巻回された巻回電極体20を有している。電池缶11は、例えばニッケル(Ni)のめっきがされた鉄(Fe)により構成されており、一端部が閉鎖され他端部が開放されている。電池缶11の内部には、巻回電極体20を挟むように巻回周面に対して垂直に一対の絶縁板12,13がそれぞれ配置されている。
本発明の第2の実施の形態に係る二次電池は、負極の容量が電極反応物質であるリチウムの吸蔵および放出による容量成分と、リチウムの析出および溶解による容量成分とを含み、かつその和により表されるものである。
図3は、第3の実施の形態に係る二次電池の構成を表すものである。この二次電池は、正極リード31および負極リード32が取り付けられた巻回電極体30をフィルム状の外装部材40の内部に収容したものであり、小型化,軽量化および薄型化が可能となっている。
負極22の容量が、リチウムの析出および溶解による容量成分により表される電池、いわゆるリチウム金属二次電池を作製した。その際、電池は、図1に示したものとした。
電解質塩としてLiPF6 に加えて、更にLiBF4 またはLiB(OCOCF3 )4 を用いたことを除き、他は実施例1−4,1−11と同様にしてリチウム金属二次電池を作製した。その際、実施例2−1,2−3では、電解液におけるLiPF6 およびLiBF4 の濃度をそれぞれ0.8mol/kg、0.2mol/kgとした。また、実施例2−2,2−4では、電解液におけるLiPF6 およびLiB(OCOCF3 )4 の濃度をそれぞれ0.8mol/kg、0.2mol/kgとした。
リチウムの吸蔵および放出による容量成分と、リチウムの析出および溶解による容量成分とを含み、かつその和により表される二次電池を作製した。その際、負極材料に人造黒鉛を用い、比較例1−4〜1−6と同様にして負極22を作製したことを除き、他は実施例1−1〜1−28と同様にして二次電池を作製した。また、溶媒は、4−フルオロ−1,3−ジオキソラン−2−オンと、FPCと、炭酸ジメチルとを表4に示した体積比で混合したものとした。更に、電解質塩にはLiPF6 を用い、電解液における濃度を1.0mol/kgとした。なお、負極22の容量がリチウムの吸蔵および放出による容量成分と、リチウムの析出および溶解による容量成分とを含み、かつその和により表されるように、正極材料と負極材料との充填量を設計した。
