The lifespan and stability of lithium-ion batteries are heavily dependent on the formation and integrity of the Solid Electrolyte Interphase (SEI) layer on the anode surface. NINGBO INNO PHARMCHEM CO.,LTD. highlights Lithium Bis(oxalate)borate (LiBOB) as a key electrolyte component that significantly enhances this crucial aspect of battery performance.

The SEI layer is a passivation film that forms during the initial cycles of a battery's life when the electrolyte components react with the anode material. A stable and uniform SEI layer is essential for several reasons: it prevents continuous electrolyte decomposition, it allows for efficient lithium-ion transport, and it protects the anode from structural degradation. An improperly formed or unstable SEI can lead to rapid capacity fade, reduced cycle life, and in severe cases, safety issues.

LiBOB excels in promoting the formation of a robust SEI layer. Its specific chemical structure allows it to decompose in a controlled manner at the anode surface, creating a thin, uniform, and ionically conductive protective film. This behavior is a significant advantage over other electrolyte salts, some of which can lead to less stable SEI layers or undergo parasitic reactions that consume active lithium. The efficacy of LiBOB in this regard makes it a preferred choice for high-performance battery applications.

By ensuring effective SEI formation, LiBOB directly contributes to the longevity of lithium-ion batteries. This means batteries can undergo more charge-discharge cycles before their capacity significantly diminishes, leading to a longer overall service life. This is particularly important for applications like electric vehicles and grid-scale energy storage, where durability and reliability are paramount. The emphasis on battery grade lithium bis(oxalate)borate quality ensures optimal SEI formation.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing materials that drive battery innovation.
