| Abstract(J) | 本研究では重要鉱物（Li・Ni・Co）の需要ー価格の相互作用を考慮した自動車の技術選択モデルを構築した．BEV普及による重要鉱物の需要増加・価格上昇が，LIBコストの高止まりを招きさらなるBEV普及を抑制する可能性が示された．リサイクル・リユース・正極材シフトによる重要鉱物需要低減の効果も評価した． Translation |
| Abstract(E) | This study develops a vehicle technology choice model that explicitly represents price–demand feedbacks for critical minerals (lithium, nickel, and cobalt). Results showed that, under the assumed scenarios, the diffusion of battery electric vehicles increased mineral demand and prices, which in turn hindered further penetration. We also evaluated mitigation strategies, including battery recycling, second-life use, and a shift toward low-cobalt cathodes. |
