LiPF6 Electrolyte for Lithium-ion Battery Research
This LiPF6-based electrolyte solution is composed of high purity LiPF6 salt, organic carbonate solvents, and some additives. The blending is performed in a dry room with low moisture to confirm that moisture and acid are well controlled. The acid and moisture content are tested before packaging in a fluorinated HDPE bottle or an aluminum bottle and sealing with aluminum-plastic bag.
The composition is as follows:
- Electrolyte salt: 1M LiPF6 (~12.5% by weight);
- Solvent: EC:EMC=3:7 (by weight);
- Additive: 1% VC.
The electrolyte formula is suitable for a preliminary evaluation of most of the energy storage materials for lithium-ion batteries. For cathode materials, it is strongly suggested not charging it above 4.2V vs. lithium with this electrolyte. Electrolyte with custom formula is available.
