Here the effect of alkyl-chain length on the reaction dynamics between alkylammonium salts (XI) and 3D PVSK matrix is studied, through examination of surface morphological and crystallographic properties of the 3D PVSK matrix. It is observed that the average crystallite size of 3D PVSK increases as XI is either spin-coated on 3D PVSK or penetrated through carbon-electrode (during the “in-situ healing” process). Secondary growth is observed for 3D PVSK, which is related to ion-exchanging reactions. Prolonging alkyl-chain length favors the secondary growth. Besides, the formation dynamics of 2D PVSK are studied. Adding alkyl-chain length increases the yields. The observations are thoroughly discussed with respect to the steric-hindrance effect held by alky-chains of XI molecule. The improved crystallization of 3D PVSK and increased yields of 2D PVSK help accelerate charge extraction and reduce recombination across the interface between PVSK and carbon-electrode (CE). Tuning alkyl-chain length of XI molecules, and the mass ratio between XI molecules and carbon black could mitigate the “in-situ healing” effect. Power conversion efficiency (<em>PCE</em>) of the carbon-electrode-based hole-conductor-free planar perovskite solar cells has been upgraded from 14% to 17%, and further upgraded to 20.4% by utilizing relatively thick CEs. Thanks to the hydrophobicity of long alkyl-chains owned by XI molecules, prolonged stability has been achieved on unsealed devices at the high-moisture environment (RH ≈ 85%), meanwhile, shelf-stability up to 6400 h has been achieved.

However, the combined effects of humidity and relatively high temperature often result in the uncontrollable formation of a detrimental PbI₂ phase in the perovskite films. As a result, the annealing process of perovskite films is highly sensitive to the relative humidity fluctuations of the environment. Under solar illumination, the undesired PbI₂ tends to decompose, accelerating the degradation of perovskite materials and severely compromising the light stability of PSCs. This issue is particularly critical for the buried interface and bulk of the perovskite films, as these regions absorb the majority of the incident light. Pre-treatment and post-treatment strategies are generally confined to address the PbI₂ issues at the buried interface and on the surface of the perovskite films, respectively. However, effectively addressing the effects of excess PbI₂ at buried interface and grain boundaries within bulk in a single step remains challenging. In this study, we propose an intermediate-treatment strategy using phthalylglycyl chloride (PTC), which involves treating the wet films with PTC prior to annealing during the formation process of the perovskite films. This approach protects the grain boundaries of polycrystalline perovskite films in advance, effectively preventing moisture-induced degradation of the perovskites and thus significantly broadening the relative humidity window of annealing process. Our results demonstrate that this strategy can successfully suppress the formation of PbI₂ at the grain boundaries and buried interface of perovskite films, thereby eliminating the PbI₂-induced degradation pathways. Our strategy significantly reduces the sensitivity to humidity fluctuations during annealing for fabricating stable PSCs, ensuring more consistent fabrication of stable PSCs. Consequently, the resulting PSCs achieve a champion power conversion efficiency of 26.1% and demonstrate excellent light stability.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"106 ","pages":"Pages 133-141"},"PeriodicalIF":13.1,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To illuminate the degradation behavior and failure mechanism of various overcharged states (100% SOC, 105% SOC, 110% SOC, and 115% SOC), multiple advanced in-situ characterization techniques (accelerating rate calorimeter, electrochemical impedance spectroscopy, ultrasonic scanning, and expansion instrument) were utilized. Additionally, re-overcharge-induced thermal runaway (TR) tests were conducted, with a specific emphasis on the evolution of the expansion force signal. Results indicated significant degradation at 110% SOC, including conductivity loss, loss of lithium inventory, and loss of active material accompanied by internal gas generation. These failure behaviors slow down the expansion force rate during re-overcharging, reducing the efficacy of active warnings that depend on rate thresholds of expansion force. Specifically, the warning time for 115% SOC battery is only 144 s, which is 740 s shorter than that for fresh battery, and the time to TR is advanced by 9 min. Moreover, the initial self-heating temperature (<em>T</em>₁) is reduced by 62.4 °C compared to that of fresh battery, reaching only 70.8 °C. To address the low safety of overcharged batteries, a passive overcharge warning method utilizing relaxation expansion force was proposed, based on the continued gas generation after stopping charging, leading to a sustained increase in force. Compared to active methods that rely on thresholds of expansion force rate, the passive method can issue warnings 115 s earlier. By combining the passive and active warning methods, guaranteed effective overcharge warning can be issued 863–884 s before TR.

However, its practical application is hindered by substantial volume expansion during cycling, which leads to material pulverization and an unstable solid electrolyte interphase (SEI) layer. Inspired by the natural root fixation in soil, we designed a root-like topological structure binder, cassava starch-citric acid (CS-CA), based on the synergistic action of covalent and hydrogen bonds. The abundant –OH and –COOH groups in CS-CA molecules effectively form hydrogen bonds with the –OH groups on the SiO surface, significantly enhancing the interfacial interaction between CS-CA and SiO. The root-like topological structure of CS-CA with a high tolerance alleviates the mechanical stress generated by the volume changes of SiO. More encouragingly, the hydrogen bond action among CS-CA molecules produces a self-healing effect, which is advantageous for repairing damaged electrodes and preserving their structural integrity. As such, the CS-CA/SiO electrode exhibits exceptional cycling performance (963.1 mA h g⁻¹ after 400 cycles at 2 A g⁻¹) and rate capability (558.9 mA h g⁻¹ at 5 A g⁻¹).
