Aluminum, while not typically used as an anode material, is a key player in lithium-ion batteries. It serves as the current collector in the cathode and for other parts of the battery. Aluminum still emerges as a promising anode candidate as seen in NCA batteries, balancing low cost, high capacity, and favorable equilibrium potential for lithiation/delithiation. Despite its potential, challenges like the formation of a compact surface oxide layer and volume changes pose hurdles to its widespread application as an anode.

3. Nickel: Powering the Cathodes of Electric Vehicles

Nickel assumes a key role in the cathodes of nickel-manganese-cobalt lithium-ion batteries and is highly prized in the electric vehicle revolution. Its attributes, including high energy density, a long cycle life, and rapid charging capabilities, position it as a key element in the journey toward sustainable transportation.

4. Copper: The Conductive Backbone of Batteries

Copper, while not a battery material that serves as a cathode or anode itself, is valued for its excellent electrical conductivity and serves as the current collector for both anode and cathode electrodes in lithium-ion batteries. Copper is used for several critical components in lithium-ion batteries due to its excellent electrical conductivity, chemical stability, and cost-effectiveness.

5. Steel: Structural Support & Durability

While not a core component, steel plays a pivotal role in constructing battery casings and other structural elements. Its inclusion ensures the stability and durability of lithium-ion batteries, providing the necessary structural support for long-term functionality

6. Manganese: Stabilizing Cathodes for Enhanced Performance

Manganese’s stabilizing role in the cathodes of nickel-manganese-cobalt (NMC) batteries contributes not only to stability but also to increased energy density. This dual function enhances the driving range of electric vehicles, making manganese a vital strategic element for battery technology. In recent years, Manganese has seen an uptick in demand thanks to its viability and cost-effectiveness.

7. Cobalt: Battery Material For Performance & Longer Lifecycles

Cobalt emerged as a key player in boosting energy density and maintaining the stability of the cathode’s layered structure. Its role in preventing structural degradation during charging and discharging cycles ensures the prolonged life of lithium-ion batteries. However, Cobalt production has been shrouded in unsustainable and harmful mining activities, which is why manufacturers are increasingly turning to recycled cobalt, which dampens the demand for mining. 

Alternatively, innovators are seeking ways to reduce cobalt use altogether. Recycled cobalt or cobalt of the secondary materials ecosystem is produced at LOHUM from used EV batteries, with industry-leading recovery rates and purity levels.

8. Lithium: The Battery Material Behind Modern Energy Storage

Lithium, powering the migration of ions between the cathode and anode, stands as the key dynamic force behind the battery power of today. Its unique properties make it indispensable for the functioning of lithium-ion batteries, driving the devices that define our modern world. Pure Lithium metal has a wide variety of use cases ranging from EV batteries, Consumer Electronics batteries, Aerospace, advanced metallurgy, medical and industrial compounds, and is a key requirement for manufacturing the Lithium Air battery, featuring a Lithium anode.

LOHUM recently became the first company outside of China to produce pure metallic Lithium, and the first in the world to produce it through battery recycling. This is a paradigm-shifting breakthrough, as Pure Lithium is the key prerequisite for Lithium-air batteries, which are considered the holy grail of all EV battery technologies, as a Lithium-air battery the size of a small backpack can power an EV for around 1000 Kilometers on a single charge.

9. Gold: The Unsung Hero in Electronics

While not a common component in lithium-ion batteries, gold’s high conductivity and resistance to tarnishing make it a valuable element in high-grade electronics. Its reliability ensures seamless operation and has diverse applications in all kinds of technology hardware. Gold is found in higher-end smartphones, laptops, vehicular electronics, etc, and may also be found in BMS circuit boards or various connector points.

10. Iron: Battery Material Key to Stability in LFP Batteries

Iron’s role in lithium iron phosphate batteries extends beyond stability. As a cathode material, it ensures good electrochemical properties and a stable structure during charging and discharging processes, contributing to reliable battery performance. Iron is why LFP batteries took off first in the market, why they are considered the baseline today, and likely will keep serving energy for decades to come.
