Abstract
This paper reports on the results of investigations into the compactibility and structure of powder materials based on lithium-containing spinels that have been considered promising candidates for electrodes of lithium-ion batteries. Dynamic compaction of the powders is accomplished using the uniaxial magnetic pulsed compaction technique, which seems to be an efficient tool for assembling flat and cylindrical lithium-ion batteries. Experiments are performed with sol-gel-derived powders of the electrode materials belonging to the class of lithium-containing spinels (LiMn2O4, Li4Ti5O12), as well as with powder coatings applied in the form of a thin uniform film to an aluminum foil. The influence of the additive type [graphite, poly(vinyl difluoride), carbon black] and temperature on the compactibility of the powder materials under the action of pressure pulses with an amplitude up to 1.6 GPa is analyzed.
