📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
蓄電池は日本のGX実現の鍵となる産業競争力領域であり、バイオ由来材料のLCA優位性はScope 3排出削減や資源調達リスク低減の観点で日本企業の材料戦略に示唆を与える。ただし開示制度や政策への直接的接続は薄い。
In the global GX context
Battery supply chains are central to global decarbonization and CBAM/Scope 3 accounting, so bio-based feedstock alternatives speak to embodied-carbon and critical-mineral risk in disclosure. The review's LCA angle is relevant to ISSB/CSRD value-chain reporting, though it offers no disclosure framework itself.

📄 Abstract（原文）
Global transition toward renewable energy sources and decarbonization has increasing demand for advanced energy storage systems, particularly high-performance batteries and supercapacitors, capable of supporting intermittent renewables and electrified transportation. Conventional energy storage devices depend heavily on petroleum-derived materials, raising concerns over resource depletion, environmental impact, and long-term sustainability. Bio-based materials derived from renewable biomass feedstocks, such as lignocellulose, agricultural waste, algae, and natural polymers, offer a promising alternative due to their abundance, low cost, biodegradability, and reduced C-footprint. Review comprehensively examines recent progress in bio-based materials for energy storage applications, focusing on three major classes: 1) biomass-derived carbons (e.g., hard carbons for sodium-ion battery anodes achieving >400 mAh g −1 specific capacity and activated carbons for supercapacitors exceeding 300 F g −1 ), 2) natural polymers and gel electrolytes (e.g., cellulose- and chitosan-based systems with ionic conductivities >10 −3 S cm −1 ), and 3) bio-inspired composites/hybrids. Achievements include enhanced cycling stability (>5000 cycles in full cells), improved rate performance, and successful device-level integration in flexible and prototype systems. Sustainability assessments highlight favourable life-cycle impacts compared to synthetic counterparts. Despite these advances, challenges persist, including performance gaps relative to commercial benchmarks, variability in biomass precursors, scalability issues, and potential land-use conflicts. Future directions emphasize genetic engineering of feedstocks, multifunctional designs (e.g., self-healing), AI driven material optimization, and expansion to emerging battery chemistries. Aligning with circular economy principles and UN Sustainable Development Goals (SDGs, 7, 12, 13), bio-based materials hold transformative potential to enable truly green energy storage technologies by 2030–2040.
