摘要

A thick film cathode has been fabricated by a screen-printing technique using LiCoO_2 paste to improve the discharge capacity in lithium ion micro-batteries. The LiCoO_2 thick film (about 6 mu m) was obtained by screen-printing, but high discharge capacity and a suitable surface roughness of printed LiCoO_2 film cathodes could not be obtained by adding carbon black only to the LiCoO_2 paste. On the other hand, the printed cathode which was prepared using the mixture of carbon-coated LiCoO_2 powders and carbon black showed a typical discharge curve of a LiCoO_2 cathode with a high discharge capacity (179 mu Ahcm~(-2)).
