Lithium sulfide (Li2S)-carbon composite positive electrodes were prepared by the spark-plasma-sintering (SPS) process for use in rechargeable lithium batteries. By the SPS treatment of Li2S and acetylene black (AB) blended powder, the strong binding between the active materials and the carbon powders were formed. Such contact effect improved the electrochemical performance of the cells with liquid electrolytes (1M LiFP6/(EC+DMC)), probably due to the increase in conductivity of the positive electrodes, though the samples prepared by the ball-milling process showed no significant capacity in the electrochemical tests.

Ceramics/carbon composites have been used widely, Such as, the magnesia/carbon refractory was used in some DC electric arc furnaces as anode, because of its high temperature performance and electrical conduction. The ceramic/carbon composite was easily oxidized in high-temperature at atmosphere with oxide, so the test of high-temperature electrically conducting properties needs protection. This paper proposed a test method and equipment for specific resistance both in room and high temperature, according to the electrically conducting property of ceramics/carbon composite. And the specific resistance of magnesia/carbon composites (C content <20%) was tested by this equipment. It is showed that, as the carbon content growing, there is a threshold at which the specific resistance falls sharply. Moreover, as the heating temperature increasing, the composites’ specific resistance shows a “gradual- sudden- slow- comparatively steady” changing process. The minimal specific resistance level of the developed ceramics/carbon composite (C content<20%) is about 10-5Ω·m.
