“Recyclers must be able to identify battery chemistry through labelling,” as reported by Recycling International from the fifth joint annual workshop on lithium-ion recycling, hosted by the United States Advanced Battery Consortium (USABC) and the Vehicle Recycling Partnership (VRP).
“Although primary design considerations for e-mobility batteries are robustness, reliability, safety and cost, it is of great importance to understand all aspects of design that ‘will likely pose particular challenges’ to the recycling industry when batteries inevitably enter the waste stream, the USABC and VRP contended. This would ease operations for vehicle and metal recyclers as well as battery dismantlers.”
According to Recycling International, Japan is hailed as a forerunner of battery labelling progress: the Battery Association of Japan enforced a colour-based labelling standard for small rechargeable batteries earlier this year which distinguishes lead-acid (grey), lithium-ion (blue), nickel-cadmium (green) and nickel-metal hydride (orange) batteries. The recent SAE Recommended Practice adhered to this colour scheme, and ‘added additional chemistry-specific information’ for the lithium-ion family of batteries because of ‘cathode choice variations’, it was noted.
Meanwhile, a possible long-term option is the use of colour-coded plastic housings to ‘add visual differentiation’ to Li-ion batteries. Ideally, the colour scheme would be (more…)
