In LIBs, LiNi<sub>x</sub>Mn<sub>y</sub>Co<sub>z</sub>O<sub>2</sub>(NMC) cathodes are one of the major cathode materials. Thus, recycling NMC cathodes from spent lithium-ion batteries is emerging because they contain abundant valuable materials, which can be considered unique “mineral” sources. Impurities are one of the main concerns for introducing recovered materials back into new battery manufacture because impurities are typically considered to impair the properties of recovered materials. However, some impurities can beneficially act as dopants or coatings. To comprehensively understand the effects of different impurities and treat impurities properly, this review summarizes the origin and species of possible impurities which can be introduced during different pretreatment processes, analyzes the methods to remove impurities, and discusses the effects of impurities on the regeneration process and recovered materials. This work also outlines future perspectives for fundamental research about impurities and relevant challenges of the recycling industry, helps academia and manufacturers to create new impurity standards of recovered cathode materials, and suggests opportunities for achieving a circular economy for the lithium-ion batteries industry.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"9 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, producing high-quality perovskite films via ambient printing remains challenging due to direct exposure to air, which easily induces additional stacking defects and triggers perovskite degradation compared to films fabricated by traditional spin-coating under inert conditions. Here, a multiple molecular interaction strategy is introduced to address this challenge by incorporating a 2-thiazole formamidine hydrochloride (TC) additive, effectively suppressing defect formation during ambient printing. The specific interactions between TC and precursor components, i.e., multiple hydrogen bonds and coordination interactions, could promote the crystallization of α-phase perovskites and reduce cation and anion vacancies simultaneously when drying in air. These endows high-quality ambient-printed perovskite films with large crystalline grains with eliminated nanovoids and low trap-densities, which improve charge carrier dynamics and prevent perovskite decomposition and hydration under thermal/humidity stress during long-term annealing/ambient storage. The unencapsulated PSCs show a high efficiency of 23.72% with good stability, i.e., realizing 92% and 95% efficiency retention after 672 h of annealing at 85 °C in a N<sub>2</sub> atmosphere and after 2088 h of storage in ambient air.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"33 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the development of anode-free batteries is hindered by their poor cycle life due to the continuous irreversible lithium (Li) consumption at the anode side. Here, a surface-functionalized alloy foil, which can gradually release active lithium to the cell upon cycling, used as the collector for anode-free batteries is proposed. The alloy foil is prestored with a certain amount of active lithium via a simple wet contacting reaction between the metal foil and liquid lithium source reagent. The prestored lithium amount can be precisely controlled by reagent concentration and contact time. When the foil is used as the anode, its alloyed surface demonstrates a low nucleation barrier for lithium deposition and a more uniform deposition behavior. More importantly, the alloy collector can rationally release active lithium to sustainably compensate for the irreversible Li consumption upon the cycling of a full cell, thus greatly prolonging the cycle life of the anode-free battery by 10 times. Besides, this technique can be extended to diverse metal collectors demonstrating its broad applicability.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"11 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BaSrNiWO<sub>6</sub>, with a B-site comprised of alternating Ni and W, exhibits high oxygen evolution activity, attributed to the evolution of a highly OER active surface phase. The redox transformation of Ni<sup>2+</sup>(3d<sup>8</sup>) to Ni<sup>3+</sup>(3d<sup>7</sup>) combined with partial W dissolution into the electrolyte from the linear Ni(3d)-O(2p)-W(5d) chains drives an in situ reconstruction of the surface to an amorphized, NiO-like layer, promoting oxygen redox in the OER mechanism. However, the high valence W<sup>6+</sup>(5d<sup>0</sup>) acts as a stabilizing electronic influence in the bulk, preventing the mobilization of lattice oxygen which is bound in highly covalent W─O bonds. It is proposed that the surface generated during the OER can support a lattice oxygen evolution mechanism (LOEM) in which oxygen vacancies are created and preferentially refilled by electrolytic OH<sup>−</sup>, while bulk O species remain stable.
