NOVELTY - Making a lithium battery or lithium ion battery involves: a) providing an electrolytic solution comprising: i) a non-aqueous electrolytic solvent, ii) a lithium containing salt, and iii) a nitrogen silylated additive; b) laminating and winding a cathode, a first porous separator, an anode, and a second porous separator; c) placing the wound laminated electrodes and separators in a battery case; d) infusing the electrolytic solution into the battery case; and e) sealing the battery case containing the electrodes, electrolytic solution and separators.    USE - For making a lithium battery or lithium ion battery (claimed) useful in applications including radios, televisions, calculators, wrist watches, hearing aids, electronics such as computers, cell phones, games and transportation applications such as battery powered and hybrid vehicles.    ADVANTAGE - The nonaqueous electrolytic solution is stable. The battery made with the non-aqueous electrolytic solution comprising nitrogen silylated compound has a long cycle life and high discharge capacity retention. The nitrogen silylated compounds, which are electrically neutral, act as scavengers for moisture and free acid in electrolytic solutions, lithium batteries and lithium ion batteries.    DETAILED DESCRIPTION - Making a lithium battery or lithium ion battery involves: a) providing an electrolytic solution comprising: i) a non-aqueous electrolytic solvent, ii) a lithium containing salt, and iii) a nitrogen silylated additive of formula (I); b) laminating and winding a cathode, a first porous separator, an anode, and a second porous separator; c) placing the wound laminated electrodes and separators in a battery case; d) infusing the electrolytic solution into the battery case; and e) sealing the battery case containing the electrodes, electrolytic solution and separators.
