The Complexities and Trade-offs of EV Battery Chemistries: LFP and NMC are dominant EV battery chemistries, with LFP being cheaper, earth-friendly but less energy-dense, while NMC offers more energy density and longer range but is expensive and reliant on scarce resources.
The world of EV battery technology is complex and constantly evolving. Currently, the dominant EV batteries are made with lithium iron phosphate (LFP) and nickel, manganese, and cobalt (NMC) chemistries. LFP batteries, which are made mostly of iron and phosphorus, are cheaper and more earth-friendly but less energy-dense. NMC batteries, which contain nickel, manganese, and cobalt, offer more energy density and longer range but are more expensive and rely on scarce resources like cobalt. The industry is working towards developing batteries that offer long range, low weight, long life, fast charging, and lower costs, but the question is whether all these features are necessary or even desirable. Sam Jaffe, VP of battery storage solutions at Esource, explains the history and current state of EV battery chemistries, shedding light on the complexities and trade-offs of this rapidly evolving field.
Lithium Iron Phosphate vs Nickel Manganese Cobalt Batteries in EVs: LFP batteries, cheaper due to iron use, are for lower cost, lower range EVs, while NMC batteries, costlier but with higher energy density, are for higher cost, higher range EVs. Factors like historical investments, recent market shifts, and technological advancements influence the split between the two.
The choice between lithium iron phosphate (LFP) and nickel manganese cobalt (NMC) batteries in electric vehicles (EVs) largely depends on energy density, cost, and geographical factors. LFP batteries, which are cheaper due to the use of iron instead of nickel, tend to be used in lower cost, lower range vehicles. On the other hand, NMC batteries, which offer higher energy density, are used in higher cost, higher range vehicles. This division is influenced by historical decisions, such as China's early investment in LFP technology, and recent shifts in the market, like Tesla's success with NCA ternary chemistry. The current split between LFP and NMC batteries in Chinese EVs is approximately 50-50, with LFP being used in smaller and plug-in hybrid cars, and NMC being used in larger or higher end cars. However, there is a recent resurgence of interest in LFP due to advancements in technology and cost reductions, leading to a potential reversal of this trend. Ultimately, the decision between LFP and NMC batteries is driven by a complex interplay of technological, economic, and geopolitical factors.

The development of advanced batteries, specifically those utilizing lithium metal anodes, is a key area of focus for startups in the silicon industry. These batteries, particularly those using solid state technology, have the potential to offer significant improvements in energy density and efficiency. However, the battery supply chain is currently experiencing inflationary pressures due to both general economic trends and the rapid growth of the battery market. This has led to increased costs for raw materials like lithium, which is essential for lithium metal anodes. Despite these challenges, it is expected that lithium pricing will eventually decline as the market stabilizes. The ultimate goal is to achieve lithium metal batteries, which would offer the most energy-dense anode material possible. It's important to note that while solid state batteries are often discussed in relation to lithium metal anodes, they can also be used with liquid electrolytes, and many companies are working on both solid state and lithium metal liquid electrolyte technologies.
Lithium Demand and Market Changes in EV Industry: The EV market's lithium demand is projected to surge, but current supply may fall short. Capital allocation towards lithium mining projects is advised. Expect a shift towards LFP, high nickel NMC/NCA, and manganese-rich, lithium-rich cathodes.
The demand for lithium is expected to significantly increase in the next decade due to the growing adoption of electric vehicles (EVs). However, the current supply may not be sufficient to meet this demand, leading to potential price bubbles and demand destruction. The speakers suggest that now is the time for capital allocation towards lithium mining projects to prepare for the 2025 requirements. The EV market is expected to see a pullback in demand outside of China due to the high lithium prices. Regarding battery chemistries, the speakers predict a trend towards three main categories of cathodes: Lithium Iron Phosphate (LFP), high nickel NMC or NCA, and manganese-rich, lithium-rich cathodes. The latter is a new area that is gaining attention as it replaces nickel with manganese in the cathode. Overall, the lithium market and EV battery technology are expected to undergo significant changes in the coming years.
Manganese batteries to dominate car industry by end of decade: Despite competition from lithium metal and solid state batteries, manganese batteries are expected to lead the car industry due to cost-effectiveness. Energy density, fast charging, and durability are key factors in battery comparison.
Manganese batteries are expected to be the most common chemistry choice for cars by the end of the decade due to their cost-effectiveness. However, the development of lithium metal and solid state batteries is a close race, but it might be challenging for them to become a major part of the car industry before 2032 due to the long battery validation timeline. Energy density, fast charging ability, and durability are crucial metrics when comparing different battery chemistries. Fast charging may not be a priority for most electric vehicle owners after they get used to the technology. The balance between cost, energy density, and fast charging is a priority for carmakers, and it remains to be seen how they will address these factors in their battery designs.
