Direct recycling of spent cathode material at ambient conditions via spontaneous lithiation

Direct recycling can facilitate the sustainable management of end-of-life spent cathodes, but is hindered by the harsh operation conditions required. An spontaneous lithiation strategy enables direct recycling of spent cathode material at ambient conditions, with clear economic and environmental benefits.

Sustainable upcycling of mixed spent cathodes to a high-voltage polyanionic cathode material

Direct recycling of critical battery materials bring promise but a challenge for the mixed cathode chemistries. Here, the authors report a sustainable upcycling approach, transforming degraded LiFePO₄ and Mn-rich cathodes into a high-voltage polyanionic material with an increased energy density and economic value.

Generative learning assisted state-of-health estimation for sustainable battery recycling with random retirement conditions

Data scarcity and heterogeneity impede the estimation of retired battery capacity. Here, Tao et al. propose a generative learning method that extends measured data space, potentially reducing curation time, cost and facilitating their sustainable reuse and recycling.
