Targray's full line of electrolytes can support any lithium ion batteries application you are working on. Backed by an extensive R&D team, we can customize any electrolyte solution based on your requirements for a specific application. In addition, at a very competitive rate, you can purchase our high-purity battery grade LIPF6 salt separately.

Liquid electrolyte solution plays a key role in transporting the positive Lithium ions between the cathode and anode. High purity electrolytes are a core component of li-ion batteries. The most commonly used electrolyte is comprised of lithium salt, such as LiPF6 in an organic solution. In addition to lithium salt, a range of additives needs to be included in the finished electrolyte to give the required properties to the electrolyte solution. These electrolyte additives improve the stability preventing dendritic formation and degradation of the solution. The specific electrolyte formulation will vary depending on the specific anode and cathode materials being used, however it is important to keep in mind that the specific additives will impact overall battery performance, especially in high energy EV applications.

In addition to our ability to offer customized electrolyte solutions, the table below lists our standard pre-set electrolyte solutions:

Targray also supplies a high phosphorous content flame retardant, DMMP, with powerful solvency. The addition of the flame retardant to a standard LiPF6 based electrolyte solution, will improve the safety of the lithium-ion battery cells. The Targray DMMP is a highly purified product containing the most pure and highest phosphorous content commercially available.
