Abstract

Official abstract text for this publication.

The present invention is a secondary battery having a high specific capacity and good cycleability, and that can be used safely. The secondary battery is manufactured to include an anode formed from a host material capable of absorbing and desorbing lithium in an electrochemical system such as a carbonaceous material, and lithium metal dispersed in the host material. The anodes of the invention are combined with a cathode including an active material, a separator that a separates the cathode and the anode, and an electrolyte in communication with the cathode and the anode. The present invention also includes a method of preparing an anode and a method of operating a secondary battery including the anode of the invention.

First claim

Opening claim text (preview).

What is claimed is: 1. An electrochemical cell, comprising: (A) a cathode comprising an active material capable of being electrochemically lithiated, wherein the cathode does not comprise electrochemically removable lithium prior to the initial charge; (B) an anode separated from said cathode by a separating material, wherein the anode comprises a host material capable of absorbing and desorbing lithium in an electrochemical system and finely divided lithium metal powder dispers…
