Electrodialysis as a solution for Lithium-ion battery disposal

Lithium-ion battery disposal

It is the rapid development of using lithium-ion batteries as an ideal path to green future that is causing a negative impact on the environment due to the negative environmental impact of lithium mining and especially with the lithium-ion battery disposal.

Recycling lithium-ion batteries

Recycling lithium-ion batteries is the right solution for the question how to dispose of used lithium-ion batteries.

MEGA lithium battery recycling solution makes the recovery process more effective including higher purity of the commodity product while decreasing the operating costs. Our unique electrodialysis technology is developed especially for lithium recycling companies.

Possible applications for lithium extraction from batteries:

Car batteries (electromobility)
Energy storage devices
Mobile phone and other devices

MEGA electrodialysis for lithium battery recycling companies

Why use electrodialysis in the lithium battery recycling process

The application of electrodialysis in lithium extraction processes provides different variability depending on the feedstock content (conventional electrodialysis, electrodialysis in a special configuration, and in a special configuration with complexation).

In the lithium battery recycling process the electrodialysis in special configuration is highly recommended. ED acts as a double replacement reaction system and therefore recovers Li₂CO₃ and also KF, K₂SO₄.

Special configuration ED is a direct route to carbonate, without the need to produce hydroxide and neutralize it. Achieving high purity of lithium carbonate. Li yield over 90 %.

MEGA special ED is used in the hydrometallurgical processing to ensure the lithium battery recycling process reliably profitable. Simplification of the process - omitting some industrial steps (no need to consider evaporation).

Benefits of Electrodialysis in Lithium battery recycling

Huge reduction of unit operation steps (technology complexity)
Double replacement reaction aided with membranes
Achieved high Li₂CO₃ purity
Price of production
It is possible to separate Li from Na, K, Rb by precipitation
Possibility of mother liquor recycling to the neutralization step

How does it work

Electrodialysis in a special configuration for lithium salts processing is an electro-membrane separation processes that use ion-exchange membranes and electric potential difference as driving force for salt ions transportation.

The main objective for special ED is to convert Li₂SO₄ from feed solution containing trace different ions into commodity Li₂CO₃.

MEGA special ED makes recycling efficient and sustainable to recover key materials from all types of lithium-ion batteries.
