View moreEvery year, many waste batteries are thrown away without treatment, which is damaging to the environment. The commonly used new energy vehicle batteries are lithium cobalt acid battery, lithium iron phosphate (LIP) battery, NiMH battery, and ternary lithium battery.
Spent LIBs are considered hazardous wastes (especially those from EVs) due to the potential environmental and human health risks. This study provides an up-to-date overview of the environmental impacts and hazards of spent batteries. It categorises the environmental impacts, sources and pollution pathways of spent LIBs.
The full impact of novel battery compounds on the environment is still uncertain and could cause further hindrances in recycling and containment efforts. Currently, only a handful of countries are able to recycle mass-produced lithium batteries, accounting for only 5% of the total waste of the total more than 345,000 tons in 2018.
The environmental impact of battery emerging contaminants has not yet been thoroughly explored by research. Parallel to the challenging regulatory landscape of battery recycling, the lack of adequate nanomaterial risk assessment has impaired the regulation of their inclusion at a product level.
Nevertheless, the leakage of emerging materials used in battery manufacture is still not thoroughly studied, and the elucidation of pollutive effects in environmental elements such as soil, groundwater, and atmosphere are an ongoing topic of interest for research.
