Abstract

The researchers at CIC energiGUNE and Hydro-Quebec have developed a process for the delithiation of carbon-free olivine by the addition of carbon in the presence of an oxidizing agent such as persulfates.

Added value

  • Improvement of the electronic conductivity by any source of carbon.
  • Upscaled and cost-effective synthesis of heterosite FePO4.
  • Non-Critical raw materials.
  • FePO4 could be used in semi-solid flow cells.

Application of the technology

  • Stationary energy storage applications.
