The Battery Recycling Committee of the Society of Automotive Engineers (SAE) is developing a chemistry identification system for automotive batteries. The intention is to support the efficient recycling of rechargeable battery systems used in transportation applications with a maximum voltage greater than 12V (including SLI batteries). More information is available here.
According to Battery Council International’s July newsletter, recyclers in the US are concerned that some types of lithium batteries are very similar to lead batteries in size, shape and colour, and could cause a dangerous incident if fed into a smelter. The Association of Battery Recyclers has recommended a durable form of battery identification because labels can deteriorate over a battery’s lifetime. SAE have advised that they are willing to work with the industry to address these risks.
