Optimizing the p charge of S in p-block metal sulfides for sulfur reduction electrocatalysis

Wuxing Hua et al.

Summary: Understanding sulfur conversion chemistry is crucial for the development of sulfur-based high-energy-density batteries. The relationship between the electronic structure of the catalyst and its activity remains unclear. In this study, we establish a direct correlation between the p electron gain of S in p-block metal sulfides and the apparent activation energies (E-a) for the SRR, specifically the Li2Sn to Li2S conversion. The highest p charge is observed in bismuth sulfide, resulting in the lowest E-a and a high SRR rate.

Topotactic Transformation of Surface Structure Enabling Direct Regeneration of Spent Lithium-Ion Battery Cathodes

Kai Jia et al.

Summary: Recycling spent lithium-ion batteries (LIBs) is crucial to address resource shortage and environmental pollution. A challenge in direct recycling of spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode is the disruption of Li+ transport due to electrostatic repulsion from a rock salt/spinel phase formed on the cycled cathode surface. In this study, a topotactic transformation of the rock salt/spinel phase into Ni0.5Co0.2Mn0.3(OH)2 and then back to NCM523 cathode was proposed, enabling improved lithium replenishment and comparable performance to pristine cathodes after regeneration.
