This LiPF6-based electrolyte solution is widely used as the electrolyte for lithium-ion batteries. It is composed of high purity LiPF6 salt, distilled organic carbonate solvents, and some additives. The blending is performed in a dry room to confirm that moisture and acid are well in control. The acid and moisture content are tested before packaging it in a fluorinated HDPE bottle or an aluminum bottle which is then sealed with an aluminum-plastic bag.
The electrolyte has the following formula:
- Electrolyte salt: 1M LiPF6 (~12.5% by weight);
- Solvent: EC:EMC=3:7 (by weight);
- Additive: 1% VC.
The electrolyte formula is suitable for the evaluation of most of the energy storage materials for lithium-ion batteries. It can be used for coin cells, pouch cells, cylindrical cells and other types of lithium-ion cells. For a test of cathode material, it is strongly suggested not charging the cell above 4.2V vs. lithium. Electrolyte with custom formula is available. There is a bunch of electrolyte additives to choose from. All are battery-grade with high purity.

This electrolyte solution or lithium salt sample is packaged in fluorinated HDPE/aluminum bottles with moisture strictly controlled (normally less than 20 ppm). The bottle is tightly closed and sealed with an aluminum bag. Please handle it and store it in a glovebox with inert atmosphere or a dry room. Avoid from high-temperature heating or igniting. 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 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 American customers. International shipping is available. The estimated delivery date will be sent when the order is confirmed.
