【摘要】 在干电池中用膨胀石墨代替乙炔黑作为电芯材料。通过试验,发现新型干电池的性能不比现行电池性能差,许多方面已超过乙炔黑电芯干电池。本研究发现膨胀石墨中存在的杂质对电池的自放电现象有决定性影响,并提出了今后继续研究的方向。更多还原

【Abstract】 The expansion graphite replaced acetylene black as electrical core material in dry battery. It has been found by experiment that the performances of new-type dry battery were not inferior to ones of present battery, which has advantages over acetylene black in many aspects. It has been found by present research that the impurities in expansion graphite have determintive effects on phenomena of self-discharge of battery. The continuous direction of research was pointed out.更多还原
