▎ 摘  要

NOVELTY - A composition comprises chalcogen, one-dimensional anatase material, and optionally conductive material. USE - Composition used for forming electrode e.g. cathode used for energy cell e.g. rechargeable lithium ion battery for use in electrical device (all claimed). ADVANTAGE - The composition has improved cycle life and high specific capacity, and provides rechargeable lithium-ion batteries with high gravimetric energy density. The energy cell comprising the energy cell has excellent cycle life, cycle stability, cycle characteristics, and cycle characteristics. The electrode formed using the composition has excellent electrical conductivity, and reduced volume expansion of sulfur during discharge, and improved cycle stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: electrode, which comprises the composition; energy cell, which comprises the electrode; method for discharging or charging the energy cell; and manufacture of composition.
