摘要：
NaxCoO2/Co3O4 layered nano-composite was prepared through the exfoliation, stacking, and sintering processes. Although almost no electrical conduction was observed at low temperatures, a significant increase in conductivity was observed above 750K, and it reached 1.2 x 10(2) Scm(-1) at 1200 K, which is comparable to that of Na0.7CoO2. Seebeck coefficient also largely increased above 750 K. This observation might be associated with the electrical behaviors Of Co3O4 at high temperature.
