Abstract

A sintered electrode having a sintered composite material is provided. The composite material contains (A) active-material particles, (B) solid-state electrolyte particles from an inorganic lithium ion conductor, (C) a particulate conductivity additive from an electrically conductive material and (D) a fibrous material, with weight proportions N(A) to N(D) of components (A) to (D) in the composite material satisfy the following: N (A)>N (B)>N (C), N (D). A solid-state lithium-ion battery containing such sintered electrode is also provided.
