摘要：

Various carbonaceous particles having a core-shell structure, produced from graphite and pseudo-graphite coated with pitch-blended phenol resin and green mesophase-pitch coated with phenol resin and ground graphite powder, were investigated as active materials for negative electrodes. The particles with natural graphite cores, as well as those with pseudo-graphite cores, were stable both in 1 M LiClO4-PC:EC (50:50) electrolyte and in 1.5 M LiBF4-PC:EC:BL (25:25:50) electrolyte, and showed excellent electrical capacities. Those produced from green mesophase-pitch cores were of markedly deformed configuration and showed large capacity gains with only small additions of graphite powder to the phenol coating material. Negative electrodes, in which the particles containing natural graphites cores were blended with petroleum coke in various ratios, showed that it may be possible to produce cells with specific discharge voltage curves, by varying the ratio of this blend.
