If the price of nickel goes from US$20,000 to US$50,000, this adds US$1580 in costs to the typical 60 kWh electric vehicle battery pack, and the price of the metal briefly touched US$100,000 due to the sanctions levied on Russia. Tesla's move to bet on cheaper iron-based LFP batteries for its Model 3 and Model Y looks rather smart now.
