本研究は、再生可能エネルギー貯蔵向けに鉛蓄電池、ニッケル水素電池、LiFePO₄電池を比較。放電試験と負荷最適化により、LiFePO₄が最高電圧と最長放電時間を示し、低内部抵抗が高レート動作に有利と確認。交換頻度やリサイクル性を考慮すると、LiFePO₄が推奨されるが、低コスト重視の用途では鉛蓄電池も選択肢となる。
English
This study compares lead-acid, NiMH, and LiFePO4 batteries for renewable energy storage. Discharge tests and load optimization show LiFePO4 achieves the highest voltage and longest discharge, with low internal resistance favoring high-rate operation. Considering replacement frequency and recyclability, LiFePO4 is recommended, though lead-acid remains viable for low-cost, mature-recycling scenarios.

📄 Abstract（原文）
<title>Abstract</title> <p>Battery selection for renewable energy storage is a technology-choice problem rather than a simple comparison of nominal capacity or purchase price. Here, we quantitatively compare lead-acid, a nickel-metal hydride cell, and LiFePO₄ using common-load discharge testing, LiFePO₄ load-resistance optimization, and linked lifecycle and sustainability interpretation. Under identical discharge conditions, LiFePO₄ retained the highest operating voltage and the longest discharge duration, whereas lead-acid showed the shortest useful discharge, and the nickel-metal hydride cell remained intermediate. The optimization dataset further showed that maximum measured LiFePO₄ power occurred at the lowest tested resistance, consistent with low internal resistance and favorable high-rate operation. When these results are interpreted together with replacement frequency, maintenance, recyclability, and environmental trade-offs, LiFePO₄ emerges as the most defensible option for repeated-use renewable energy storage applications, while lead-acid remains relevant where mature recycling infrastructure and low upfront cost dominate decision-making. The analysis, therefore, moves beyond a simple chemistry ranking and offers a technology-level framework for battery selection under the practical constraints of renewable energy deployment.</p>
