Facts High voltage batteries to enter our waste stream en masse ~2020; Quantity predictions vary; trends indicate exponential growth; Li-ion is lighter and smaller; will eventually dominate and overtake NiMH for most electrification applications; Existing battery recycling processes have evolved around consumer industry…must adapt to meet unique challenges of HV traction batteries: Larger and heavier (more difficult transport and handling), Less intrinsic value, High voltage handling requirements, No ‘chemistry convergence' sorting and labeling implications, Li-oriented recycling processes today oriented towards consumer cells or stationary energy storage batteries; Recycling processes for HV (traction) batteries mostly pilot scale (or lab); Three recycling technology approaches with specific pros and cons; Factors: chemistry, scale, output stream.
