Title:
A cathode active material, its manufacturing method, and an accumulating electricity device
Document Type and Number:
Japanese Patent JP6061160
Kind Code:
B2
Abstract:
A negative-electrode active material is used for a negative electrode, the negative-electrode active material including: agglomerated particles including nanometer-size silicon produced by heat treating a lamellar polysilane having a structure in which multiple six-membered rings constituted of a silicon atom are disposed one after another, and expressed by a compositional formula, (SiH)n; and a carbon layer including amorphous carbon, and covering at least some of the agglomerated particles to be composited therewith. An electric storage apparatus including the same is not only able to reduce the irreversible capacity, but also able to inhibit the generation of “SEI.”
