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.
|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 or lithium salt sample is packaged in fluorinated HDPE/aluminum bottles with moisture strictly controlled (less than 20 ppm for electrolyte). 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.
Lithium electrolyte materials are very sensitive even sealed and stored in an inert atmosphere. We suggest replacing the electrolyte with fresh samples every 6 months.
Landt Instruments partners with leading suppliers of Lithium-ion Battery Electrolyte manufacturers in China to provide the fresh LIB electrolyte samples. Most of the products are freshly blended and packaged. The raw materials are also used for xEV battery manufacturing. Typical lead time is 2 weeks and delivery takes about a week for North America customers. International shipping is available while the delivery date may vary. The estimated delivery date will be posted when the order is confirmed.
