3M™ Battery Electrolyte HQ-115 (lithium bis-trifluoromethanesulfonimide) is a high purity electrolyte salt for use in lithium batteries. HQ-115 is widely used as an additive and as the primary salt to enhance battery performance and life.
Use of HQ-115 as an additive in high capacity lithium ion batteries can improve battery life, reduce gas generation and improve battery safety and cell impedance control, especially when cycling at high temperatures. With high conductivity, solubility, and thermal stability, HQ-115 is the ideal salt for use in lithium polymer and primary lithium ion battery systems. HQ-115 is available in a variety of grades from ultra low moisture to aqueous versions.
