Why use electrodialysis in the lithium battery recycling process

Higher lithium concentration

Simpler production process

Lower operating costs

The special ED configuration reduces the complexity of production and waste management.

High purity commodity Li₂CO₃ product where SO₄^2- < 0.05 %DMB.

Li₂CO₃ can be separated from Na, K, Rb salts by precipitation followed by ED.

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 in particular the disposal of lithium-ion batteries.

Recycling lithium-ion batteries

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

MEGA's lithium battery recycling solution makes the recovery process more effective including higher purity of the commodity product while reducing 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 use 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 for hydroxide production and neutralization. Achieving high purity of lithium carbonate. Li yield over 90 %.

MEGA’s special ED is used in hydrometallurgical processing to ensure the lithium battery recycling process is reliably profitable. This leads to simplification of the process and the omission of 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.
Achieving of high Li₂CO₃ purity.
Low operating costs.
Possibility 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 process that uses ion-exchange membranes and electric potential difference as the driving force for the salt ions transportation.

The main objective of the special ED is to convert Li₂SO₄ from feed solution containing trace amounts of different ions to the commodity Li₂CO₃.

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