LiPF6 Electrolyte for Lithium-ion Battery Research
This LiPF6-based electrolyte solution is composed of high purity LiPF6 salt, organic 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.
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.
|Chlorine (Cl)||<5 ppm|
|Sulfate (SO4)||<5 ppm|
|Sodium (Na)||<10 ppm|
|Potassium (K)||<10 ppm|
|Calcium (Ca)||<10 ppm|
|Iron (Fe)||<10 ppm|
|Lead (Pb)||<10 ppm|
This electrolyte solution is packaged in fluorinated HDPE bottles with ultra-low water content (less than 20 ppm). The bottle is tightly closed and sealed with an aluminum bag. Please handle it in an inert and moisture-free glove box or dry room. Avoid from high-temperature heating or igniting. Store in a glove box or dry room. LIB electrolyte should be stored in a PE or Teflon (PTFE) sample bottle but not a glass bottle.
