Microbial pyrazine diamine is a novel electrolyte additive that shields high-voltage LiNiCoMnO cathodes.

The uncontrolled oxidative decomposition of electrolyte while operating at high potential (> 4.2 V vs Li/Li) severely affects the performance of high-energy density transition metal oxide-based materials as cathodes in Li-ion batteries. To restrict this degradative response of electrolyte species, the need for functional molecules as electrolyte additives that can restrict the electrolytic decomposition is imminent.
