A123's US 20150155596: MULTI-CELL LITHIUM-ION BATTERIES

The first claim of A123's application:

A battery comprising: a container having a number of cell cavities; a number of electrochemical assemblies, each electrochemical assembly enfolded, one of said number of electrochemical assemblies disposed in each one of said number of cell cavities; each one of said number of electrochemical assemblies comprising: a positive electrode and a negative electrode; and a separator material between the positive electrode and the negative electrode; an electrolyte in each cell cavity from said number of cell cavities, said electrolyte comprising a lithium salt and a redox shuttle; said electrolyte and electrodes selected to, during battery operation, provide substantially a predetermined voltage across each electrochemical assembly in said each cell cavity; said redox shuttle being selected to substantially provide shuttle operations when voltage across each electrochemical assembly in each cell cavity reaches substantially another predetermined voltage; and a cover disposed on said container; said cover being permanently attached to said container so as to form a substantially hermetic seal between said cover and said container; said cover forming a seal between said each cell cavity.
