Optimizing the stack pressure is important for promoting the interfacial performances of garnet-type ceramic electrolyte (Li6.4La3Zr1.4Ta0.6O12) with Li metal anode. In this work, ASSLMBs assembled with Li6.4La3Zr1.4Ta0.6O12 electrolytes are investigated under various stack pressures. Experimental results show that 3 MPa stack pressure is the optimal choice. The Li/Li6.4La3Zr1.4Ta0.6O12/LiFePO4 battery under 3 MPa achieves a discharge capacity of 129.2 mAh g− 1 after 100 charge/discharge cycles with a capacity retention rate of 82.1%. The mechanism by which stack pressure affects the interface performance of Li6.4La3Zr1.4Ta0.6O12 electrolyte with Li anode is analyzed. A moderate stack pressure enlarges the contact area between Li6.4La3Zr1.4Ta0.6O12 electrolyte and Li anode through elastic deformation, reducing the interface resistance. Additionally, it facilitates the plastic flow of Li anode via stress yield, minimizing the contact loss of Li anode during charge/discharge process. This work presents the significance of exerting a moderate stack pressure to optimize interfacial performance between Li6.4La3Zr1.4Ta0.6O12 electrolyte and Li anode.\u0000 </div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 5","pages":"1953 - 1963"},"PeriodicalIF":2.6,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147707793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It requires pilot valve spools with exceptional surface integrity to ensure high response speed and reliability. However, for valve spools with complex geometries, conventional electrochemical polishing struggles to achieve simultaneous burr elimination, superior surface finish, and dimensional accuracy due to non-uniform material removal caused by electric field edge effects and limited electrolyte solution access. To bridge this gap, a novel electrochemical approach that integrates polishing and deburring into a single process is presented. The fundamental mechanisms of burr removal and surface evolution were first elucidated through experiments and electric field simulations on flat samples, establishing an optimal parameter window. Subsequently, a specialized rotary electrochemical machining (RECM) device was developed for valve spools. Crucially, the process was optimized through coupled electric-flow field simulations, guiding the use of rotation to control hydrodynamic conditions, counteract edge effects, and ensure uniform dissolution. The RECM-processed valve spools exhibited remarkable improvement: the low-frequency surface roughness was reduced from Sa 1.258 μm to 0.252 μm, and the high-frequency surface roughness from Sa 0.702 μm to 0.055 μm, while maintaining dimensional uniformity and eliminating burrs.

However, issues such as the wide bandgap, rapid recombination of electrons and holes, lacking charge storage capabilities, along with the practical applications results in certain challenges. In this study, TiO2 nanotube arrays doped with different molar ratios of Ce and Co (Cex-Coy/TiO2) were synthesized using a one-step anodization method. The results indicate that under illumination conditions, when carbon steel is coupled with Ce1-Co1/TiO2, its open-circuit potential (OCP) shifts negatively by approximately 300 mV and 150 mV relative to the uncoupled carbon steel photoanode materials and the coupled pure TiO2 conditions, respectively.The photocurrent density shows the 2.4 times higher than that of pure TiO2. Additionally, even when the light source was turned off, it could still provide a continuous cathodic protection for carbon steel. The enhanced photocathodic protection can be attributed to the nonlinear distribution of Ce and Co on the Cex-Coy/TiO2 surface with the gradient transition from reduced states to oxidized states at interface, which enhances the system’s light-harvesting capability and forms a heterojunction with TiO2, which enhances the separation and migration of photogenerated charge carriers.
