Lithium batteries are batteries that use lithium as an anode. This type of battery is also referred to as a lithium-ion battery [1] and is most commonly used for electric vehicles and electronics. [1] The first type of lithium battery was created by the British chemist M. Stanley Whittingham in the early 1970s and used titanium and lithium as the electrodes. Applications for this battery were limited by the high prices of titanium and the unpleasant scent that the reaction produced. [2] Today's lithium-ion battery, modeled after the Whittingham attempt by Akira Yoshino, was first developed in 1985.

While lithium-ion batteries can be used as a part of a sustainable solution, shifting all fossil fuel-powered devices to lithium-based batteries might not be the Earth's best option. There is no scarcity yet, but it is a natural resource that can be depleted. [3] According to researchers at Volkswagen, there are about 14 million tons of lithium left, which corresponds to 165 times the production volume in 2018. [4]

Extraction

Lithium is extracted on a commercial scale from three principal sources: salt brines, lithium-rich clay, and hard-rock deposits. Each method incurs certain unavoidable environmental disruptions. Salt brine extraction sites are by far the most popular operations for extracting lithium, they are responsible for around 66% of the world's lithium production. [5] The major environmental benefit of brine extraction compared to other extraction methods is that there is very little machinery needed to be used throughout the operation. [5] Whereas hard-rock deposits and lithium-rich clays both require relatively typical mining methods, involving heavy machinery. [5] Despite this benefit, all methods are continually used as they all achieve relatively similar recovery percentages. [5] Brine extraction achieves a 97% recovery percentage whereas hard-rock deposits achieve a 94% recovery percentage. [5]

Continental brine extraction

Brine extraction uses open-air evaporation to concentrate the brine over time. This results in large quantities of water being lost due to evaporation. It is worth noting that in general, this brine being evaporated has a very high salinity, making the water unusable for any agricultural or human consumption. [6] Afterwards, the concentrated brine is moved to a nearby production facility to produce Li2CO3 and LiOH•H2O. [7] These production facilities are responsible for the bulk of the atmospheric pollution caused by brine extraction sites, releasing harmful gasses such as Sulphur dioxide into the air. [8]

The majority of brine extraction sites are situated in South America, more specifically, in Chile and Argentina, where around half of the world's lithium reserves exist in a place referred to as the "lithium triangle". [5] In Chile, [9] the world's second-largest lithium producer, the nation's two active mines, run by SQM and Albemarle, are both located on the Salar de Atacama salt flat in the Atacama Desert. [10] Tests performed on the brines of these mines showed that the brine has ~350 g/L of total dissolved solids. [7] Studies on this mine and the area's water tables have shown that the total water storage of Salar de Atacama decreased by -1.16 mm per year from 2010-2017. [6] There is a complex divide among and within local communities, with some accepting payouts from the mining corporations and taking part in their community development initiatives, whilst others are either neglected by such programs or refuse the corporations' offers due to their aforementioned environmental concerns. [11] [12] In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dangerous chemicals such as hydrochloric acid leaking into the Liqi River from the nearby lithium mining facilities. [13] As a result, dead fish and large animals were seen floating down the Liqi River and other nearby rivers near the Tibetan mines. [13] After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even years. [14]

Hard-rock deposits

Lithium can also be extracted from hard-rock deposits. These deposits are most commonly found in Australia, the world's largest producer of lithium, [5] through spodumene ores. Spodumene ores and other lithium-bearing hard-rock deposits are far less abundant throughout the world than continental brines. [6] Although the deposits are far less commonly found and available for mining, the operating costs are very similar to the costs of operating a brine extraction operation. [5] As a result, hard-rock deposit extraction sites are continuing to be created and used even though salt brines are much more common to find and typically bear a smaller environmental impact. [6]

Lithium-rich clays

Extracting lithium from lithium-rich clays first involves mining the clays themselves which results in lots of atmospheric pollution. There are several minerals within clay that contain lithium such as, lepidolite, hectorite, masutomilite, zinnwaldite, swinefordite, cookeite, and jadarite. [15] After extracting these minerals from the ground, the clays are processed to extract the lithium, this is typically done through chemical reactions like acidification. [15] This chemical process can result in harmful gasses and chemicals being produced as byproducts which can easily result in pollution if not handled properly. [15] Lithium-rich clays are the third major source of lithium, although they are far less abundant than salt brines and hard-rock ores containing lithium. To be exact, lithium-rich clays make up less than 2% of the world's lithium products. [16] For comparison, brine extraction represents 39% and hard-rock ores represent 59% of the lithium production. [16]

Disposal

Some types of Lithium-ion batteries such as NMC contain metals such as nickel, manganese and cobalt, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. [17] Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. [18] As a result, some jurisdictions require lithium-ion batteries to be recycled. [19] Despite the environmental cost of improper disposal of lithium-ion batteries, the rate of recycling is still relatively low, as recycling processes remain costly and immature. [20] A study in Australia that was conducted in 2014 estimates that in 2012-2013, 98% of lithium-ion batteries were sent to the landfill. [21]

Recycling

Lithium-ion batteries must be handled with extreme care from when they're created, to being transported, to being recycled. Recycling is extremely vital to limiting the environmental impacts of lithium-ion batteries. By recycling the batteries, emissions and energy consumption can be reduced as less lithium would need to be mined and processed. [22]

The EPA has guidelines regarding recycling lithium batteries in the U.S.  There are different processes for single-use or rechargeable batteries, so it is advised that batteries of all sizes are brought to special recycling centers. This will allow a safer process of breaking down the individual metals that can be reclaimed for further use. [23]

There are currently three major methods used for the recycling of lithium-ion batteries, those being pyrometallurgical recovery, hydrometallurgical metal reclamation, and mechanical recycling. [22] A study conducted in 2016 with several recycling plants in Australia found that mechanical recycling recovered the most materials, recovering 7 of the 10 possible materials from lithium-ion batteries on average. [22] This same study also found that hydrometallurgy recovered 6 out of 10 materials on average and pyrometallurgical processes recovered only half of the possible materials on average. [22]

Pyrometallurgical recovery

The processes within the pyrometallurgical recovery include pyrolysis, incineration, roasting, and smelting. [22] Right now, most traditional industrial processes are not able to recover lithium. The main process is to extract other metals including cobalt, nickel, and copper. There is a very low recycling efficiency in materials and use of capital resources.  There are high energy requirements along with gas treatment mechanisms that will produce a lower volume of gas byproducts. [24]

Hydrometallurgical metals reclamation

Hydrometallurgy uses chemical reactions to dissolve materials into a solution, which is later precipitated to retrieve the desired raw material. [22] This method of recycling destroys all organic materials, such as plastic, during the process. [22] That being said, Hydrometallurgy does achieve a very high purity in the recovered metals, making it a good recycling method. [22] It is commonly used for copper recovery. This method has been used for other metals to help eliminate the problem of sulfur dioxide byproducts that more conventional smelting causes. [25]

Direct/mechanical recycling

Direct or mechanical recycling involves breaking down old lithium-ion batteries to extract important, usable components and/or materials to be re-used with new batteries. [22] This process involves shredding or crushing old batteries and then extracting the materials afterwards. [22] This can lead to cross-contamination which can result in certain materials or components becoming unrecyclable. [22] While this form of recycling is an option, it still generally remains more expensive than mining the ores themselves. [26] With the rising demand for lithium-ion batteries, the need for a more efficient recycling program is detrimental with many companies racing to find the most efficient method. One of the most pressing issues is when the batteries are manufactured, recycling is not considered a design priority. [27] The advantage of this recycling method is that it generally involves very little pollution if any from the process, whereas the previous two methods can both produce harmful chemicals and gasses. [22]

Application

There are many uses for lithium-ion batteries since they are light, rechargeable and are compact. They are mostly used in electric vehicles and hand-held electronics, but are also increasingly used in military and aerospace applications. [28]

Electric vehicles

The primary industry and source of the lithium-ion battery is electric vehicles (EV). Electric vehicles have seen a massive increase in sales in recent years with over 90% of all global car markets having EV incentives in place as of 2019. [29] With this increase in sales of EVs and the continued sales of them we can see a significant improvement to environmental impacts from the reduction of fossil fuel dependencies. [30] There have been recent studies that explore different uses for recycled lithium-ion batteries specifically from electric vehicles. Specifically the secondary use of lithium-ion batteries recycled from electric vehicles for secondary use in power load peak shaving in China has been proven to be effective for grid companies. [31] With the environmental threats that are posed by spent lithium-ion batteries paired with the future supply risks of battery components for electric vehicles, remanufacturing of lithium batteries must be considered. Based on the EverBatt model, a test was conducted in China which concluded that remanufacturing of lithium-ion batteries will only be cost effective when the purchase price of spent batteries remains low. Recycling will also have significant benefits to environmental impacts. In terms of greenhouse gas reduction we see a 6.62% reduction in total GHG emissions with the use of remanufacturing. [32]

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans. This applies to industries that generate wastewater with high concentrations of organic matter, toxic pollutants or nutrients such as ammonia. Some industries install a pre-treatment system to remove some pollutants, and then discharge the partially treated wastewater to the municipal sewer system.

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas:

Usage of electric cars damage people’s health and the environment less than similar sized internal combustion engine cars. While aspects of their production can induce similar, less or different environmental impacts, they produce little or no tailpipe emissions, and reduce dependence on petroleum, greenhouse gas emissions, and deaths from air pollution. Electric motors are significantly more efficient than internal combustion engines and thus, even accounting for typical power plant efficiencies and distribution losses, less energy is required to operate an electric vehicle. Manufacturing batteries for electric cars requires additional resources and energy, so they may have a larger environmental footprint in the production phase. Electric vehicles also generate different impacts in their operation and maintenance. Electric vehicles are typically heavier and could produce more tire and road dust air pollution, but their regenerative braking could reduce such particulate pollution from brakes. Electric vehicles are mechanically simpler, which reduces the use and disposal of engine oil.
