Abstract

Core-shell particles may be based on red lead coated with pyrogenically produced titanium dioxide and/or a pyrogenically produced aluminum oxide, and a process may prepare such core-shell particles which may be used in lead-acid batteries. The red lead may include PbO2 in a range of from 25 to 32 wt. %.
