Magnesium Hexafluorophosphate Mg(PF6)2 New Electrolyte additives
Magnesium Hexafluorophosphate Contact Joyce Luo sales03@chemfish.com www.chemfish.com Mg(PF 6 ) 2 -based electrolytes for Mg-ion batteries have not received the same attention as the analogous LiPF 6 -based electrolytes used in most Li-ion cells owing to the perception that the PF 6 – anion decomposes on and passivates Mg electrodes. No synthesis of the Mg(PF 6 ) 2 salt has been reported, nor have its solutions been studied electrochemically. Here, we report the synthesis of the complex Mg(PF 6 ) 2 (CH 3 CN) 6 and its solution-state electrochemistry. Solutions of Mg(PF 6 ) 2 (CH 3 CN) 6 in CH 3 CN and CH 3 CN/THF mixtures exhibit high conductivities (up to 28 mS·cm –1 ) and electrochemical stability up to at least 4 V vs Mg on Al electrodes. Contrary to established perceptions, Mg electrodes are observed to remain electrochemically active when cycled in the presence of these Mg(PF 6 ) 2 -based electrolytes, with no fluoride (i.e., MgF 2 ...
