Electrochemical cell for lithium battery and lithium battery comprising such an electrochemical cell

摘要

The invention relates to an electrochemical cell for a lithium battery comprising a positive electrode comprising graphite, a negative electrode and an electrolytic solution disposed between the positive and negative electrodes, the electrolytic solution comprising at least one lithium salt and at least one less a solvent. According to the invention, the lithium salt is lithium oxalyldifluoroborate LiODFB and the solvent is an organic solvent. The invention also relates to a lithium battery comprising such an electrochemical cell and to the use of such an electrochemical cell or lithium accumulator in the fields of consumer devices (cellular telephony, digital photography , micro-computing), security or aerospace.
