The performance of lithium-ion batteries can be significantly impacted by ambient temperature, particularly at lower degrees. Traditional electrolyte salts often struggle in cold conditions, leading to reduced capacity and slower charge/discharge rates. Lithium Bis(fluorosulfonyl)imide (LiFSI) has emerged as a groundbreaking solution to these challenges, offering remarkable improvements in low-temperature battery performance. NINGBO INNO PHARMCHEM CO., LTD. is a key provider of this advanced material, enabling battery developers to overcome the limitations of extreme temperatures.

At the heart of LiFSI's effectiveness lies its unique molecular structure, which influences the properties of the electrolyte and the Solid Electrolyte Interphase (SEI) layer. The SEI layer is crucial for battery operation, preventing direct contact between the electrolyte and the electrodes, which can lead to unwanted side reactions. In cold environments, the SEI layer formed with conventional salts can become brittle and resistive, hindering ion transport. LiFSI, however, contributes to the formation of a more stable and flexible SEI layer. This enhanced stability significantly reduces the high and low-temperature resistance of the SEI, allowing lithium ions to move more freely even when temperatures drop.

This improved ion mobility at low temperatures directly translates into better battery capacity and electrochemical performance. For applications such as electric vehicles that operate in diverse climates, or portable devices used in colder regions, the enhanced low-temperature performance of LiFSI is a critical advantage. Battery manufacturers seeking to buy LiFSI are investing in the ability to offer products that perform reliably across a wider temperature spectrum, a key differentiator in a competitive market. The ability of LiFSI to reduce capacity loss during storage and improve discharge capacity at low temperatures is paramount.

The high purity of LiFSI supplied by NINGBO INNO PHARMCHEM CO., LTD. further ensures that these low-temperature benefits are realized without introducing detrimental impurities. By providing a high-quality LiFSI product, we empower battery manufacturers to develop more robust and versatile energy storage solutions. As the demand for batteries that can operate reliably in all conditions continues to grow, LiFSI stands out as a critical electrolyte salt that addresses a fundamental performance challenge, making it indispensable for future battery innovation.
