Lithium-ion Electrolyte HF-Reduction Device

LithChem is in the final testing stages of a lithium-ion electrolyte HF-reduction device, the J-RESIN SYSTEM. The device can effectively reduce the HF level in lithium-ion battery electrolyte down to <5ppm HF, regardless of the initial electrolyte HF level. The J-RESIN SYSTEM incorporates a specialized resin in its design, which is an easy-to-use device that is extremely efficient and effective in removing free HF from lithium-ion electrolyte. The system can also remove traces of color from lithium-ion electrolyte.

The current test unit, about 25cm2 and 50cm tall, has the capacity to remove approximately 80,000 parts of free HF, regardless of the level of HF in any particular electrolyte. Example: for electrolyte with an acid number of 80ppm HF, the system can treat 1,000kg (80,000ppm ÷ 80ppm/kg) of this electrolyte with a resulting acid number of <5ppm acid. Likewise if 40ppm HF electrolyte were to be treated, the system would reduce the HF level of 2000kg (80,000ppm ÷ 40ppm/kg) of that material down to <5ppm HF. Other systems with varying capacities will also soon be available.
