EV battery supply may be less fragile than feared as markets swap key materials

• EV batteries have undergone four major technology shifts since the early 2010s, including replacing cobalt with nickel and shifting from NMC to LFP batteries to manage costs and material availability
• Over 25% of new cars sold globally are now electric, with 39 countries surpassing key market adoption thresholds, indicating continued growth potential
• Researchers recommend governments focus on international cooperation and trade alliances rather than solely pursuing new mining projects, given the market's demonstrated ability to adapt to supply pressures

Summary: EV Battery Supply Shows Resilience Through Material Substitution

Key Findings

New research published in *Cell Reports Physical Science* (April 2026) reveals the electric vehicle battery market has demonstrated greater adaptability to raw material shortages and price fluctuations than previously anticipated. The study, led by researchers at Lund University and Stockholm Environment Institute, analyzed 15 years of EV battery development and identified four major technological shifts since the early 2010s.

Major Material Substitutions

Researchers documented significant material swaps driven by supply constraints and cost pressures:

• Cobalt to Nickel: Manufacturers reduced cobalt dependence due to extraction bottlenecks, rising prices, and ethical concerns surrounding mining practices
• NMC to LFP: Batteries using nickel-manganese-cobalt (NMC) minerals are being replaced by lithium iron phosphate (LFP) batteries, which offer lower costs and reduced reliance on critical materials

Market Context

Electric vehicles now represent over 25% of global new car sales, with 39 countries surpassing this market penetration threshold. Despite rapidly increasing material volumes required, the industry has proven capable of quickly commercializing alternative battery technologies.

Policy Implications

Researchers suggest governments reconsider their approach to designating "critical materials," given the market's demonstrated flexibility. Instead of focusing exclusively on mining expansion, they recommend:

• Promoting cooperation across the entire battery value chain
• Forming international partnerships and trade alliances
• Supporting sustainable import/export frameworks
• Expanding mineral refinement capabilities beyond China's current dominance, particularly within the EU

The findings challenge conventional assumptions about supply chain fragility in the energy transition.
