The energy required for the burning process is supplied from the combustion of volatile matter, plastic substances, and carbonaceous compounds present in the battery waste. Although pyrometallurgy processes are a simple way to recover lithium from battery waste, they also have some drawbacks.
Lithium recovery from battery waste Battery waste is one of the main secondary sources of lithium. It has been estimated that about 40% of total lithium consumption is in batteries ( Swain, 2016 ). At the end of the batteries’ lives, this huge amount of lithium is disposed of as waste.
In a different study, Vellingiri et al. (2018) used a combination of sulfuric acid and Na 2 SO 3 and recovered 99.5% zinc from alkaline battery waste. The use of a reducing agent as well as an auxiliary agent enhances the recovery percentage of zinc from the battery waste.
After pre-treatment, subsequent purification techniques like leaching, solvent extraction, ion exchange, and precipitation methods are applied to recover lithium. Due to the strong bonding of organic binders, sometimes the leaching process takes a long time, and the leaching efficiency is also reduced marginally.
In 2020, about 5 billion tons of LIB waste was generated globally. By 2030, waste production will reach to 11 billion tonnes ( Forum and (PACE), 2019; Golmohammadzadeh et al. (2018). The main raw material of LIBs is lithium (Li), which is one of the most sought-after critical metals. Another significant waste resource is alkaline batteries.
In another study, lithium-manganese-oxide battery waste was roasted at 800º C for 45 min. A water-leaching process was applied to the roasted residue, and 99.13% of Li was recovered from the waste ( Zhang et al., 2018 ).
