Title: Chemical overcharge protection of lithium and lithium-ion secondary batteries

Abstract

This invention features the use of redox reagents, dissolved in non-aqueous electrolytes, to provide overcharge protection for cells having lithium metal or lithium-ion negative electrodes (anodes). In particular, the invention features the use of a class of compounds consisting of thianthrene and its derivatives as redox shuttle reagents to provide overcharge protection. Specific examples of this invention are thianthrene and 2,7-diacetyl thianthrene. One example of a rechargeable battery in which 2,7-diacetyl thianthrene is used has carbon negative electrode (anode) and spinet LiMn{sub 2}O{sub 4} positive electrode (cathode). 8 figs.
