Abstract
The invention relates to the simultaneous use of a first salt comprising a nitrate anion (NO3−) and a second salt comprising an anion other than nitrate, at least one of the first and second salts being a lithium salt, as ionic conductivity promoters in a rechargeable lithium-metal-gel battery. The invention also relates to a lithium-gel battery comprising a mixture of said first salt and said second salt, to a non-aqueous gel electrolyte comprising such mixture and to a lithium battery positive electrode comprising said mixture.
