“…[27,28] Despite of these appealing advantages, the hazards of F-based materials are also non-negligible. For instance, the preparation of LiPF 6 generally involves the usage of highly corrosive chemicals such as hydrogen fluoride (HF), phosphorus trichloride, and phosphorus pentafluoride, [29,30] raising severe concerns on production safety and environmental pollution. [31] In addition, the detrimental HF from the reaction between LiPF 6 and water can etch most of the battery components, which requires strict control on water contents for battery production and applications.…”

Rechargeable batteries with higher energy densities and sustainability have been intensively pursued in the past decades, driven by the wide applications such as electric vehicle industry and grid energy storage. As an ancient battery system born ≈140 years ago, chlorine (Cl)–based batteries have been actively revisited in recent years, because of their impressive electrochemical performance with the low–cost and sustainable features, making them highly attractive candidates for energy storage applications. In this Perspective, the historical development of Cl–based batteries is reviewed at first, focusing on the progresses in new battery chemistries enabled by various Cl–based electrolytes. An emphasis is then placed on the unique cathode and anode chemistries enabled by rational regulation of Cl–based electrolytes. At last, the challenges and prospects, particularly the obstacles for real–world applications of state–of–the–art Cl–based batteries are introduced.

“…The PF 5 is reacted with LiF suspended in CH 3 CN in a contacting column to produce LiPF 6 , which is then purified from the solvent by crystallization. Ohe and Ohe et al present a combination of methods, where LiF and red phosphorus (P) are heated at 300 °C in the presence of F 2 gas and at 25 °C in the presence of ClF 3 to produce LiPF 6 . Wilmann, Naejus, and co-workers , propose to first prepare pyridinium hexafluorophosphate (C 5 H 5 NHPF 6 ) from the neutralization of phosphorus hexafluoro acid (HPF 6 ) with pyridine (C 5 H 5 N).…”

In this work, the production of lithium hexafluorophosphate (LiPF6) for lithium-ion battery application is studied. Spreadsheet-based process models are developed to simulate three different production processes. These process models are then used to estimate and analyze the factors affecting cost of manufacturing, energy demand, and environmental impact due to greenhouse gas (GHG) emissions. The results indicate that in a facility with a capacity of making 10,000 t per year of LiPF6 the cost of production is around $20 per kg of LiPF6, energy consumption is around 30 GWh per year, and the emission of greenhouse gases in CO2-equivalent gases is around 80 t per day. The impact of change in process and economic parameters on the cost of production, energy demand, and emissions is studied. In addition, a few insights on reducing the cost of production are presented. Finally, the impact of varying LiPF6 costs on the overall cost of a Li-ion battery ($ kWh–1) is presented.
