Once a Li-ion battery has reached the end of its first life, several options can be considered.

Key Points: 
  • Once a Li-ion battery has reached the end of its first life, several options can be considered.
  • This looks to maximize the value of the battery by using it in another less demanding application.
  • Recycling Li-ion batteries looks to recover valuable materials, which either form part of the cell or other components of the battery pack.
  • Nevertheless, both second-life Li-ion batteries and recycling are expected to play an important role in managing end-of-first-life Li-ion batteries over the coming years.
