of inorganic compounds other than oxides or hydroxides, e.g. sulfides, selenides, tellurides, halogenides or LiCoFy; of polyanionic structures, e.g. phosphates, silicates or borates

Introduced: July 1974

Titles differ between systems:

IPC: of inorganic compounds other than oxides or hydroxides, e.g. sulfides, selenides, tellurides, halogenides or LiCoF; of polyanionic structures, e.g. phosphates, silicates or borates

CPC: of inorganic compounds other than oxides or hydroxides, e.g. sulfides, selenides, tellurides, halogenides or LiCoFy; of polyanionic structures, e.g. phosphates, silicates or borates

IPC:

Electrodes > Electrodes composed of, or comprising, active material > Selection of substances as active materials, active masses, active liquids > of inorganic compounds other than oxides or hydroxides, e.g. sulfides, selenides, tellurides, halogenides or LiCoF; of polyanionic structures, e.g. phosphates, silicates or borates

CPC:

CPC subdivides this area 5x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.

IPC defines codes here since 2010.
