As a new foreign trade service provider driven by technological transformation and export business, HiSiaddi has built a "1+2+3+4=1" service system and can supply LiFSI sourced from multiple well-known original manufacturers.
Equipped with R&D capabilities, HiSiaddi has conducted multiple rounds of factory inspections of LiFSI manufacturers, gaining objective and in-depth understanding of various brands. We regularly analyze different LiFSI manufacturers for clients to assist in product matching. Below is a brand recommendation case.
Contact HiSiaddi customer service for additional brand and model comparative analysis.
The client is ESS POWER B.V., a premium energy storage battery enterprise headquartered in Amsterdam, the Netherlands, and a leading European manufacturer of industrial and commercial energy storage systems. Its products cover large-scale European energy storage power stations and premium commercial building backup power supplies, complying with EU REACH, CE, IEC 62619 and ISO 9001 standards. The client demands ultra-high-purity, low-impurity, high-stability LiFSI compatible with high-temperature energy storage operating conditions, with an annual procurement volume of 50 tons, qualifying as a typical overseas mid-to-high-end client.
This was the client’s first procurement of Chinese LiFSI, with limited awareness of domestic brands. After contacting five leading manufacturers (Tianci Materials, Kangpeng Technology, New Zhubang, Do-Fluoride, Yongtai Technology), each factory only promoted its own products while avoiding discussion of competitors’ strengths. The client lacked horizontal comparative data to judge which brand and model matched its high-temperature energy storage formula, fearing selection errors that would damage battery cycle life and safety and stall procurement. The client entrusted HiSiaddi with objective brand analysis, precise model recommendation and full technical endorsement.
HiSiaddi neutrally analyzed mainstream models from five leading domestic manufacturers across six dimensions: production capacity scale, technical routes, core indicators, application scenarios, client reputation and price ranges, presenting balanced strengths and weaknesses without bias toward any single brand.

Combining the client’s core demands of high-temperature energy storage operating conditions, ultra-high-purity requirements, 50-ton annual procurement volume and moderate budget, HiSiaddi eliminated Do-Fluoride and Yongtai Technology (substandard indicators only fit low-end scenarios) and screened 2 mid-to-high-end brands with 3 models covering three tiers: extreme performance, stable mass production and cost performance, providing clear selection guidance.
Core indicators: Purity 99.95%, water ≤40ppm, free acid ≤8ppm, metal ions ≤0.8ppm, thermal stability ≥200℃ Matching rationale: Solid products deliver exceptional thermal stability with zero gas generation under high-temperature storage and extended cycle life, perfectly compatible with the client’s 85℃ high-temperature energy storage conditions. Controllable particle size facilitates long-distance European transportation and has passed validation by premium European energy storage clients with strong market reputation.
Core indicators: Purity 99.97%, water ≤35ppm, free acid ≤7ppm, metal ions ≤0.5ppm Matching rationale: Extreme purity with ultra-low impurities and excellent solubility, ideal for the client’s flagship premium energy storage projects. Strong compatibility enables direct substitution of imported LiFSI without extensive formula adjustments.
