Nevertheless, their widespread application still faces several key obstacles, including low initial Coulombic efficiency (ICE) and a fast capacity decay rate. Pre-lithiation as an effective strategy has been widely used to address these issues through compensating for active lithium loss. This review comprehensively analyzes the failure mechanisms of Si/C anodes during cycling, including structural degradation, SEI instability, and kinetic constraints. The recent pre-lithiation progresses are evaluated in three categories based on the different manufacturing stages: pre-lithiation during active material synthesis, pre-lithiation during electrode fabrication, and pre-lithiation after full-cell assembly. This classification integrates pre-lithiation strategies and industrial production workflows, enabling a systematic evaluation of the relationships between cost, lithium utilization efficiency, and battery performance. Novel techniques such as dry pre-lithiation, bifunctional electrolyte additives, and topological intercalation are also investigated for their contributions to improved ICE, cycling stability, and energy density. Although significant progress has been made, obstacles related to the degree of pre-lithiation, lithiation uniformity, and process compatibility continue to restrict the large-scale application of Si/C anodes. Finally, a detailed analysis of these challenges in Si/C anodes is provided, and future development prospects are discussed for next-generation LIBs with enhanced performance and expanded commercial viability.</p>","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 3","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70155","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a combined first-principles density-functional theory and experimental study reveals how polymer polarity and chemical composition regulate charge transfer at PVDF/polymer interfaces, including Nylon, PDMS, PVC, PE, PTFE, and FEP. The results demonstrate that polar β-PVDF/polymer heterostructures exhibit substantially stronger interfacial charge transfer than nonpolar systems, driven by the intrinsic built-in electric field of β-PVDF. The transferred charges primarily originate from the functional groups of the polymers, and the charge transfer magnitude follows the sequence β-PVDF/Nylon > β-PVDF/PDMS > β-PVDF/PVC > β-PVDF/PE > β-PVDF/PTFE > β-PVDF/FEP, corresponding to electron flow from low work function polymers toward the high work function β-PVDF. Furthermore, these theoretical trends are supported by experimental results, which confirm that β-PVDF-based TENGs deliver higher electrical outputs than α-PVDF-based systems and follow the same material-dependent sequence. This work elucidates the polarization-driven and material-dependent mechanisms of interfacial charge redistribution, providing design principles for high-output and controllable TENGs.</p>","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 3","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the hydrogel electrolyte possesses a large number of hydrophilic functional groups that act as “grippers” to restrict the movement of water molecules and mitigate the side reactions induced by water molecules. This hydrogel strategy involves a simple and reproducible preparation process, while simultaneously improving the electrochemical performance of aqueous zinc-ion batteries, thus providing a new insight into the structural design of hydrogel electrolytes.\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 2","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70162","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147708039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
