Blockchain and IoT-Driven Sustainable Battery Recycling: Integration and Challenges

Abstract

As a distributed ledger technology, blockchain demonstrates broad prospects in battery recycling due to its decentralized, transparent, and secure characteristics. However, practical implementation faces challenges including technical barriers, cost investments, regulatory adjustments, and data privacy protection. This paper comprehensively introduces blockchain applications in battery recycling, explaining its principles, advantages, and real-world deployment. It analyzes existing problems in current recycling systems, such as data fragmentation, inefficient reverse logistics, and regulatory failures. Furthermore, blockchain-IoT integration applications, including full lifecycle data management, intelligent monitoring, and logistics optimization, are discussed. Innovative business models are proposed, such as decentralized recycling platforms, data-driven frameworks, and sharing economy models. The importance of establishing unified industry standards is emphasized, along with an outlook on future development directions. Through systematic analysis, this study offers insights for researchers and practitioners and serves as a reference for promoting sustainable development in the battery recycling industry.
