It is typically determined based on anode properties such as resistance and the expected operating C-rate, under the assumption that Li plating is primarily governed by anode characteristics. However, this study reveals that the voltage profile of the cathode at the end of charge (EOC) also plays a significant role by influencing the anode cut-off voltage under high C-rate conditions. This study compares LiFePO<sub>4</sub> (LFP) and LiCoO<sub>2</sub> (LCO) cathodes, which exhibit markedly different voltage slopes at EOC. As the C-rate increases, the LFP full-cell shows less capacity reduction than the LCO cell, owing to the steep voltage rise near EOC that acts as a buffer against overpotential-induced cut-off. As a result, the graphite anode in the LFP cell becomes more lithiated, leading to a lower anode potential and increased risk of Li plating. Three-electrode measurements, differential voltage (dV/dQ) analysis, Li plating analysis, and long-term cycling tests of LFP cells (&gt; 4 Ah) with varying N/P ratios consistently support this mechanism. The findings highlight that the cathode voltage slope at EOC significantly affects anode behavior and should be considered in N/P ratio design to ensure safer and longer-lasting LFP batteries.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"7 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145283430","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 fundamental phase evolution pathways during lithiation of TMTs largely remain ambiguous owing to the lack of direct evidence. Herein, ferrous tungstate (FeWO<sub>4</sub>) is strategically selected as a characteristic TMT anode material to investigate the time-resolved structural evolution and reaction kinetics during lithiation. Previously unexplored two-step conversion reaction mechanism during the lithiation of FeWO<sub>4</sub> is explicitly revealed by coupling <em>in situ</em> transmission electron microscopy (TEM) with synchronized electron diffraction (ED) observation. Impressively, the single-crystal Li<sub>2</sub>WO<sub>4</sub> is identified as the intermediate phase by <em>in situ</em> lattice-resolution imaging and density functional theory (DFT) calculation. Upon further Li<sup>+</sup> intercalation, the lattice spacing of Li<sub>2</sub>WO<sub>4</sub> progressively expands along with distortion and cracking of ordered lattice fringes, ultimately resulting in full conversion of Li<sub>2</sub>WO<sub>4</sub> into Fe, W and Li<sub>2</sub>O phases. The final delithiation products can be recovered to the FeWO<sub>4</sub> phase and therefore reversible phase conversion reactions can be maintained with cycling. The <em>in situ</em> TEM observations not only decipher the whole lithiation process of the FeWO<sub>4</sub> anode, but more importantly establishes a general mechanistic framework for understanding the Li storage mechanism of other TMT anodes.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"28 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145283431","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}

Here, a universal strategy of charge self-injection is proposed to increase the storage depth of triboelectric charges to improve the volume charge density of TENG. This charge self-injection strategy (CSS) effectively enhances the electric field inside dielectric layer by short-circuiting the positive and negative electrodes of TENG, and promotes the drift of triboelectric charge into the dielectric layer, thereby significantly increasing volume charge density. In addition, volume charge density is further enhanced by stabilizing the electric field inside dielectric layer in the intermittent working mode and further exploring the charge drift process. Finally, CSS enhanced TENG achieves an effective areal charge density of 93.47 μC/m<sup>2</sup>, which is 2.81 times that of traditional-TENG.
