Currently, the main drivers for developing Li-ion batteries for efficient energy applications include energy density, cost, calendar life, and safety. The high energy/capacity anodes and cathodes needed for these applications are hindered by challenges like: (1) aging and degradation; (2) improved safety; (3) material costs, and (4) recyclability.
Renewable energy sources: Lithium-ion batteries can store energy from renewable resources such as solar, wind, tidal currents, bio-fuels and hydropower. Using renewable energy means we get fuel for our cities and homes from sources that are naturally replenished and create fewer carbon emissions than fossil fuels.
Storing energy in lithium-ion batteries offers a set of advantages that can help us achieve sustainability goals considering energy use: for instance, allowing us to ease our reliance on fossil fuels in favor of renewable energy resources and lithium-ion batteries. However, with these advantages come a set of drawbacks throughout the battery''s supply chain. Below is a look at some of these advantages and drawbacks.

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]
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]
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]
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]
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]
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]
