Overview

Review examines geothermal silica's potential as a battery anode material, highlighting benefits and challenges for sustainable energy.

Key Points

  • The aim is to explore geothermal silica as a precursor for silicon-based lithium-ion battery anodes and its implications for sustainability.
  • Reviewed characteristics and availability of geothermal silica from geothermal energy sources.
  • Evaluated processing steps to convert geothermal silica into silicon, focusing on magnesiothermic reduction methods.
  • Compared electrochemical performance of geothermal silica-derived materials with traditional sources.
  • Geothermal silica can contain 50-98 wt% silica with favorable properties for battery applications.
  • Some geothermal silica materials delivered capacities exceeding 372 mAh g−1, indicating competitive performance.
  • Specific surface areas of 50-150 m2 g−1 may enhance processing and electrochemical behavior.
