Under the low carbon goal, recycling power batteries (PBs) from new energy vehicles (NEVs) is a crucial measure to address resource shortages and reduce emissions. This study examined insufficient collaboration among responsible entities imperfections in market mechanisms within PB system. We overcome limitations of traditional tripartite evolutionary game models by developing four-party model that incorporates government, manufacturers, recyclers, consumers investigate strategic interactions extended producer responsibility (EPR) framework. Using MATLAB 2023a numerical simulations Lyapunov stability analysis, we found system’s efficiency depend on stakeholder effective government policy guidance. The system evolves toward Pareto optimal state when all parties adopt proactive strategies. Meanwhile, ensuring substantial profits for manufacturers recyclers critical feasibility stable operation compliant channels. While are more sensitive subsidies than consumers, consumer decision-making key stability. Long-term excessive may lead diminishing marginal benefits. Strategic recommendations provided policymakers stakeholders enhance sustainability

Lithium (Li) is essential for decarbonization strategies, such as electric vehicles and renewable energy storage, which experiences the largest growth rates among metals required low-carbon technologies. To meet this demand, raw materials sector must increase current capacities develop new at untapped deposits. Understanding life cycle impacts crucial to avoid severe environmental burden shifts in future. Although site-specific inventories exist, they do not allow a comprehensive global assessment of Li sector, particularly capturing technological developments. address this, our study presents inventory model brines that maintains parameters while providing perspective. We define core modeling carbonate (Li2CO3) production systematic approach addressing data gaps. Our employs class-based structure 30 mapped processes from literature quantifies technical flows. Overall, we cover 25 sites, representing 300 kilotonnes (90%) Li2CO3 an additional 315 potential future production. One key finding sites using direct extraction have 7-fold higher climate change than conventional technologies on average, water scarcity are doubled average. The difference result larger brine mass be treated due lower grades. Furthermore, allows implications Li-ion battery analyzed.
