LITHIUM SALTS AND BATTERYELECTROLYTES DEVELOPMENT/

Ultra-pure chemicals for lithium ion batteries

YOUR KEY PARTNER.

Ultra-pure chemicals designed to fit all voltage cathode/anode systems

Pure lithium salts or formulated electrolyte solutions at your convenience

High voltage corrosion resistance along with battery lifetime and calendar life

Synergies with the other Arkema battery products

FORANEXT® KEY TECHNOLOGIES

LiFSI and LiTDI are known as the next blockbuster lithium salts but their performance is highly related to their purity. Due to a smart industrial process, Arkema’s ultra-pure LiFSI and LiTDI present outstanding performance.

LiTDI increases lifetime at high temperature: SEI stabilization, HF and water scavengers and cathode protective film.

BATTERY ELECTROLYTE SOLUTIONS.

Arkema developed two new lithium salts with very high purity industrial process to improve overall battery performance for multiple cathode and anode technologies.

Extended lifetime additive Improved SEI stability High chemical stability versus acids, water Better electrochemical stability (4.7V) Improved aluminum passivation Enabling synergies with LiFSI

High ionic conductivity High electrochemical stability (>5V) Better thermal stability Main salt or additive value Best salt for lithium metal technology
