2Li-ion battery recycling

• Extended Producer Responsibility (EPR)

• Producers = person/company putting batteries on the market in a certain Member State

• Producers are responsible for EoL management

• Industrial and automotive batteries: take back and recycling obligation

• Portable batteries: collection target and recycling obligation

• Recycling Efficiency

• > 50% of battery weight (excl. H2O) has to be recycled; emissions in air/water, waste fractions and incinerated fractions ≠ recycling

• In situ use of battery materials (replacing chemicals, but not as source of energy) = recycling

• Battery packs: outer casing doesn’t count as input/ouput battery material, but EV batteries are not considered as ‘packs’ � ‘external jacket’ is input/output material

3Li-ion battery recycling

Battery recycling concepts

• All recycling concepts are combinations of ‘pre-treatment’ (disassembling, shredding, pyrolysis) and metallurgical processes (pyro or hydro)

• Optimum combination depends on battery chemistry and design, scale leverage effects, processes, …

Early process steps Later process steps

Pre-treatment

Low investment cost; low environmental burden; high

labour cost

High metal losses; high labour cost; moderate

investment costs

Metallurgy

High investment; moderate environmental burden; low

labour cost

Efficient metal recovery; low labour cost; moderate

investment cost

4Li-ion battery recycling

• Dismantling• Labour intensive: Manual � semi-automated � mechanical breaking• Safety: State of Charge?

• Shredding• Charged batteries + inflammable solvents = fire risk; � inert atmosphere or cryogenic

shredding• Alternatively: pyrolysis before shredding

• Pyrometallurgy• Optimum conditions for maximum metal yields

• Hydrometallurgy:• Robustness of the process to cope with variety of input materials

• General• Quality of the recycled products: should meet industry standards• Cost: complex material flow and (still) small quantities

Battery recycling concepts: challenges

Umicore

Battery Recycling

Recycling of Li-ion and NiMH batteries

Umicore Ultra High Temperature (UHT) technology

Innovative technology for metal recovery

Capacity: 7000 mt• 250 mio mobile phone batteries (≈ 30 gr) • 200,000 HEVs (≈ 35 kg) • 35,000 EVs (≈ 200 kg)

Metals recovery: Co – Ni – Cu Slag recovery:

• NiMH: rare earth concentrate (Ce, La, …)• Li-Ion: use in construction + future

potential for recovery Li

Flue dust: controlled separation of F

Energy efficient: use energy of battery (electrolyte, metals, plastics) to obtain high temperature.
