Lithium Battery Recycle & Recovery

Description

Lanran’s BPED technology enables resource recovery from spent lithium batteries by converting leachates into lithium hydroxide and sulfuric acid, closing the loop in battery manufacturing.

Process

  • Spent batteries undergo dismantling, crushing, and leaching to produce a Li-rich solution.
  • After impurity removal, purified Li₂SO₄ solution enters BPED system.
  • BPED converts Li₂SO₄ into LiOH and H₂SO₄.
  • LiOH is crystallized; H₂SO₄ is recycled for leaching.

Applications

  • Recycling LiFePO₄ and NMC batteries
  • Closed-loop resource recovery for lithium

Key Advantages

High lithium recovery efficiency

Acid by-product reused, reducing chemical consumption

Clean process with no secondary pollution
