The ability of a lithium-ion battery (LIB) to hold its charge when not in use, known as charge retention or low self-discharge, is a critical performance parameter for many applications. Self-discharge can lead to inconveniences for users and impact the overall usability of battery-powered devices. Advanced electrolyte additives, such as Lithium Difluorophosphate (LiDFP), are instrumental in combating this issue. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing high-quality LiDFP (CAS No. 24389-25-1) to help battery manufacturers enhance this vital aspect of battery performance. As a leading LiDFP manufacturer in China, we are dedicated to supplying materials that contribute to superior battery functionality.

Self-discharge in LIBs is primarily caused by parasitic reactions occurring within the battery system. These reactions can include the continuous decomposition of electrolyte components, the formation of dendrites on the anode, or unwanted side reactions at the electrode-electrolyte interfaces. These processes consume active lithium and electrolyte, leading to a gradual loss of stored charge. Minimizing these parasitic reactions is key to achieving excellent charge retention.

Lithium Difluorophosphate acts as a crucial additive by promoting the formation of a stable and effective Solid Electrolyte Interphase (SEI) layer on the anode. This SEI layer acts as a physical and electrochemical barrier, effectively blocking the pathways for electrolyte decomposition and lithium consumption. A well-formed SEI, facilitated by LiDFP, significantly impedes the parasitic reactions that lead to self-discharge. By stabilizing the electrode-electrolyte interface, LiDFP ensures that the battery’s stored energy remains intact for longer periods, a crucial benefit for applications like portable electronics, medical devices, and electric vehicles where consistent power availability is essential.

Furthermore, LiDFP’s contribution to improved high-temperature performance also indirectly aids in reducing self-discharge. At elevated temperatures, parasitic reactions tend to accelerate, exacerbating the self-discharge problem. By enhancing the thermal stability of the SEI and the overall electrolyte system, LiDFP helps to suppress these temperature-dependent degradation mechanisms. This dual benefit – improved SEI stability and enhanced thermal resistance – makes LiDFP a highly valuable additive for achieving excellent charge retention across a range of operating conditions.
