High-Voltage Electrolyte Chemistry for Lithium Batteries
More surprisingly, only a very small amount of the electrolyte is required to maintain the long cycle of the battery, and when a small amount of blank electrolyte is used, the battery will fail early because the electrolyte is exhausted. Ji et al. synthesized pentafluorocyclotriphosphazene (PFPN) as a bifunctional additive in the electrolyte.
Fundamentals and perspectives of lithium-ion batteries
The letter ''C'' stands for battery chemistry, here it is Li, ''R'' stands for round battery shape, and the number indicates the approximate dimensions of the cell. Several other capital English letters are used to define different shapes of a battery, for example: ''F'' stands for ''flat'', ''S'' stands for ''Square'', ''P'' stands for ''Not Round'', and ''R ...
