the inventors of the subject matter of the present disclosure have developed an electrolyte solution usable in a lithium or lithium - ion battery , among other types of batteries that offers one or more of the following : improved stability , elimination of the risk of unintentionally producing hydrochloric acid , improved thermal stability , and reduced production costs associated with manufacturing a battery . indeed , the inventors have discovered an unexpected result that by including an additive to a dinnimitride salt , the discharge capacity of the battery may improve beyond what is available in the prior art , including lipf6 . for example , production costs may be decreased since lidn is not water - sensitive , so precautions to ensure that the compound is not exposed to water may be avoided . further benefits include thermal stability since lidn may be more thermally stable when compared to lipf6 .
