Shape-Controlled Reversible Li Plating-Stripping for Stable and High-Rate Anode-Free Lithium Metal Batteries.

Adv Mater

March 2025

Frontiers Science Center for Flexible Electronics, Institute of Flexible Electronics, Northwestern Polytechnical University, Xi'an, 710072, P. R. China.

Anode-free lithium metal batteries are promising toward high-energy-density power sources with low-cost, but their practical applications are challenged by poor cycling stability and low rate capability. Herein, a shape change-free and lithium-free anode that well controls the reversible Li plating-stripping is reported, which is composed of a highly-ordered hollow ZnO matrix with a surface-coated lithium-phosphorus-oxynitride (LiPON) layer. The ZnO matrix supplies sufficient cavities and lithiophilic sites to facilitate uniform Li plating/stripping within the hollow cavity, while the LiPON layer maintains stable solid-electrolyte interphase from mechanical and electrochemical damage.

Introduction: Multiple micronutrient deficiencies might increase the adverse outcome during pregnancy and after birth. Considering the WHO recommendations since 2016 and scientific evidence from previous studies that multiple-micronutrient supplementation (MMS) is more effective than iron folic acid (IFA) in improving pregnant women's health, it is imperative to conduct an economic evaluation to assess the cost-effectiveness of MMS compared with IFA.

Methods: We conducted a systematic review from PubMed and Scopus to identify the cost-effectiveness analyses of MMS compared to IFA for pregnant women up to January 2024.
