Es wird eine Batteriezelle dargelegt, die eine negative Elektrode, eine Lithium-Mangan-reiche positive Elektrode und einen Elektrolyten mit einem Methylenmethandisulfonat-Additiv umfasst. Der Elektrolyt mit dem Methylenmethandisulfonat-Additiv sättigt die negative und die Lithium-Mangan-reiche positive Elektrode, sodass sich während eines Zyklierens der Batterie eine positive Elektrolytgrenzfläche an einer Oberfläche der Lithium-Mangan-reichen positiven Elektrode bildet. Die positive Elektrolytgrenzfläche führt dazu, dass eine Gleichstromimpedanz der Batteriezelle für einen gegebenen Ladezustand geringer ist als eine Gleichstromimpedanz einer ansonsten gleichen Batteriezelle ohne das Methylenmethandisulfonat-Additiv.
