Organofluorophosphates (OFPs) have been reported to pose substantial health hazards due to their structural similarities to pesticides and nerve agents. Formation of OFPs in lithium ion batteries (LIBs) due to hydrolysis of the conducting salt lithium hexafluorophosphate (LiPF6) and the reaction with the organic carbonate solvents that make up the electrolyte has been discussed in literature.

Enabling aqueous processing of positive active materials to replace toxicologically critical N-methyl-2-pyrrolidone could significantly reduce the ecologic and economic footprint of lithium ion battery production. Processing additives are key to elevate the performance of aqueously processed electrodes beyond the state of the art. [...]

Organic electrode materials are capable candidates for next-generation greener energy storage solutions. One advantage is that their electrochemical performance can be tuned by structural modification. [...]

The electrochemical response of layered lithium transition metal oxides LiMO2 [M=Ni, Mn, Co; e. g., Li(Ni0.5Mn0.3Co0.2)O2 (NMC532)] with single-crystalline architecture to slow and fast charging protocols and the implication of incomplete and heterogeneous redox reactions on the active material utilization during cycling were the subject of this work. The role of the active material size and the influence of the local microstructural and chemical ramifications in the composite electrode on the evolution of heterogeneous state of charge (SOC) distribution were deciphered.
