The continuous advancement in battery technology hinges on the development of superior electrolyte materials. Lithium Bis(fluorosulfonyl)imide (LiFSI), with CAS number 171611-11-3, has emerged as a star player in this arena, significantly boosting the performance of lithium-ion batteries. As a leading manufacturer and supplier in China, we are at the forefront of providing this critical advanced battery electrolyte additive to researchers and manufacturers globally.

Chemically, LiFSI is represented as LiN(SO₂F)₂. Its molecular structure endows it with exceptional properties that directly translate to enhanced battery performance. One of its most lauded attributes is its high thermal stability, meaning it can withstand elevated temperatures without decomposing. This is crucial for batteries operating in demanding environments or those subjected to high charge/discharge rates, contributing significantly to battery safety and longevity. When developers look to buy LiFSI for lithium ion battery applications, this stability is a primary consideration.

Another key technical advantage of LiFSI is its remarkable ionic conductivity. The fluorosulfonyl groups contribute to weaker interactions between the lithium cation and the imide anion, facilitating easier ion transport. This high conductivity is essential for reducing the internal resistance of the battery, allowing for faster charging and discharging rates. For product formulators, this means the ability to design batteries with higher power density – a significant leap forward for applications like electric vehicles and grid-scale energy storage.

LiFSI also plays a vital role in improving the solid electrolyte interphase (SEI) layer formed on the anode. The SEI layer is critical for battery stability, preventing continuous electrolyte decomposition. LiFSI contributes to the formation of a more stable, uniform, and ionically conductive SEI layer, particularly at lower temperatures. This enhancement is crucial for maintaining battery capacity over extended cycles, especially under challenging operating conditions. Our commitment to providing high purity chemical LiFSI ensures these benefits are realized.

While LiFSI offers numerous advantages, it's important to note its potential for corroding aluminum current collectors at higher concentrations. However, this issue is often addressed through the use of synergistic additives, such as LiBOB, which can mitigate this effect. The combination of LiFSI with other additives allows for fine-tuning electrolyte performance to overcome specific limitations. For those seeking to purchase LiFSI, understanding these nuances is part of leveraging its full potential.
