ACTIVE MATERIAL BASED ON BUNDLES OF ONE-DIMENSIONAL TRANSITION METAL DICHALCOGENIDE NANOTUBES FOR USE IN LITHIUM BATTERIES AND ACCUMULATORS

摘要

The invention relates to the production and utilization of an electrode material in lithium-ion batteries and accumulators that is based on one-dimensional transition metal dichalcogenide nanotubes and an electronic conductor. The material based on bundles of one-dimensional transition metal dichalcogenide nanotubes and an electronic conductor affords incorporation of lithium into lithium-ion batteries and incorporation of lithium into lithium-ion accumulators. The amount of lithium incorporated into the material based on bundles of one-dimensional transition metal dichalcogenide nanotubes and an electronic conductor depends upon the percentage of the active material and upon the construction thereof and may amount up to 3.2 moles (2.3 moles on average) of lithium per mole of transition metal chalcogenides. The average voltage of the release of lithium from the active material based on bundles of one-dimensional MoS2 nanotubes and an electronic conductor is 1.1 V as measured against a Li/Li+ half-cell.
