A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Lithium-ion batteries contain lithium and high-grade copper and aluminium. Depending on the active material, they may also contain cobalt, nickel and rare earth metals. To prevent a future shortage of cobalt, nickel, and lithium and to enable a sustainable life cycle of these technologies, recycling processes for lithium batteries are needed. [15]
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 reduces energy consumption, reduces greenhouse gas emissions, and results in 51.3% natural resource savings when compared to discarding them in landfills. [8] Recycling can potentially lower the overall energy emissions of battery production as the LIB recycling industry grows larger. [2]
Li-Cycle, a Canadian lithium-ion battery recycling company, is another major player in the industry. The company says it currently has four recycling facilities in North America that can process ...
Lithium ions intercalate between the layers upon discharging, remaining between the lattice planes until the battery gets charged, at which point the lithium de-intercalates and moves to the anode. [4] Points in a solid solution phase diagram between the end members LiCoO 2, LiMnO 2, and LiNiO 2 represent stoichiometric NMC cathodes. [5]
An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower ...
1973: Adam Heller proposed the lithium thionyl chloride battery, still used in implanted medical devices and in defense systems where a greater than 20-year shelf life, high energy density, and/or tolerance for extreme operating temperatures are required. [ 13 ] However, this battery employs unsafe lithium metal and was not rechargeable.
