This study introduces a Nb⁵⁺ concentration-gradient doping strategy based on a “lattice-charge” coupling concept to achieve multiscale stabilization of cobalt-free LiNi₀.₈Mn₀.₂O₂ (NM82). A decreasing Nb gradient from surface to bulk forms a “surface-reinforced, bulk-stabilized” structure. The Nb-rich surface preferentially occupies Ni sites, forming a robust Nb-O covalent network that strengthens transition metal-oxygen bonding, suppresses oxygen release, and mitigates interfacial side reactions. Concurrently, the Nb-lean bulk maintains efficient Li⁺ transport and electronic conductivity. High-valence Nb⁵⁺ also modulates Ni valence via charge compensation, reducing Ni³⁺ content to suppress Jahn-Teller distortion and stabilize the NiO₆ octahedral framework. This enhances reversibility of the H2→H3 phase transition. Electrochemical and structural analyses, supported by first-principles calculations, confirm a “lattice reinforcement–charge regulation” mechanism that strengthens the oxygen framework and improves thermal and cycling stability. The optimized NM82-1.0 cathode retains 95.4% capacity after 100 cycles at 4.3 V and 89.2% at 4.5 V, shows a >25 °C increase in exothermic peak temperature, and reduces precursor costs by over 13% versus commercial NCM.

While machine learning offers promising solutions, training models to overcome the high heterogeneity of retired batteries requires massive degradation data, leading to high testing costs and substantial energy waste. Here, we reveal the potential to recover large-scale and high-quality second-life battery datasets from field data to assist in diagnosing the health of retired batteries. By seamlessly fusing deep learning and domain knowledge, we enabled the accurate recovery of capacity labels for operating data without regular fully charging or discharging calibrations. To validate the proposed method, we develop a large-scale degradation test on 96 realistic retired batteries, performing over 50,000 charge/discharge cycles to simulate different stationary energy storage scenarios with 24 charge-discharge intervals. With only 3 capacity measurements available over the second-life, the proposed method accurately recovers the capacity labels with a root mean square error below 30 mAh. Furthermore, the health diagnostic model trained on regenerated dataset is comparable to the model trained on real data, with an almost negligible error of less than 5 mAh. More importantly, we expect to save at least 98% of test time, electricity and energy consumption to generate datasets cost-effectively. This study highlights the potential of field data to bridge the critical data gap in diagnosing the health degradation of retired batteries.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"86 ","pages":"Article 104947"},"PeriodicalIF":20.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146089610","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}
