Lithium ion batteries are rechargeable batteries that are commonly used in portable electronics. The lithium ion is responsible for charging and discharging of these batteries. Organic electrolytes are used in which lithium may be added as LiPF6. Over time, the hexafluorophosphate degrades partially and other phosphates may be found. These phosphates are separated on a Metrosep A Supp 5 - 250/4.0 column and detected applying conductivity detection after sequential suppression.
