摘要： An active material for batteries or cells having improved discharge characteristics and comprising a fluorinated graphite produced by fluorination of graphite with fluorine, the fluorinated graphite containing substantially no unreacted graphite and having a degree of fluorination such that the weight or fluorine content thereof is increased by a further fluorination under conditions equal to or severer than the fluorination conditions adopted to the production of the fluorinated graphite. The use of artificial graphite having a Franklin's P-value of at least 0.45 as a starting material is effective for further improving the discharge voltage and the capacity.

摘要： Continuous fluorination of carbon is carried out by employing an apparatus for contact reaction of solid powder and reactive gas which comprises a horizontal reactor having a trough provided with weirs (e.g. height: 1 to 6 mm., interval: 5 to 30 cm.) and a vibrating means for vibrating the trough, and in which carbon particles supplied continuously are transported on the trough in a form of thin layer by the vibration of the trough while continuing the reaction by contacting efficiently the carbon particles with a fluorine gas. The contact reaction is efficiently conducted without accumulating the reaction heat to produce the fluorinated carbon in high yields, and the process is useful for the mass production. The apparatus is also useful for various contact reaction of a solid powder and a reactive gas.
摘要翻译： 碳的连续氟化是通过采用固体粉末和反应性气体接触反应的装置进行的，该装置包括具有设置有堰的槽的水平反应器（例如，高度为1至6mm，间隔为5至30cm），和 用于振动槽的振动装置，其中连续供应的碳颗粒通过槽的振动以薄层的形式在槽上输送，同时通过有效地使碳颗粒与氟气接触来继续反应。 有效地进行接触反应而不积累反应热，以高产率生成氟化碳，该方法对于批量生产是有用的。 该装置还可用于固体粉末和反应性气体的各种接触反应。
