As a new type of artificial visual sensory devices, photoelectric memristors can fully simulate synaptic performance and have great prospects in the development of biological vision. However, due to the urgent problems of nonlinear conductance and high-energy consumption, its further application in high-precision control scenarios and integration is hindered. In this work, we report an optoelectronic memristor with a structure of TiN/CeO<sub>2</sub>/ZnO/ITO/Mica, which can achieve minimal energy consumption (187 pJ) at a single pulse (0.5 V, 5 ms). Under the stimulation of continuous pulses, linearity can be achieved up to 99.6%. In addition, the device has a variety of synaptic functions under the combined action of photoelectric, which can be used for advanced vision. By utilizing its typical long-term memory characteristics, we achieved image recognition and long-term memory in a 3 × 3 synaptic array and further achieved female facial feature extraction behavior with an activation rate of over 92%. Moreover, we also use the linear response characteristic of the device to design and implement the night meeting behavior of autonomous vehicles based on the hardware platform. This work highlights the potential of photoelectric memristors for advancing neuromorphic vision systems, offering a new direction for bionic eyes and visual automation technology. </p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01816-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present a modulation layer composed of porous SnP0.94/CoP p-n heterojunction particles (SCP), synthesized applying the Kirkendall effect. The unique heterointerfaces in the SCP induce a fully ionized depletion region and built-in electric field. This provides strong Li affinity, additional adsorption sites, and facilitated electron transfer, thereby guiding dendrite-free Li nucleation/growth with a low Li deposition overpotential. Moreover, the strategic design of the SCP, accounting for its reaction with Li, yields electronically conductive Co, lithiophilic Li-Sn alloy, and ionic conductive Li3P during progressive cycles. The mixed electronic and ionic conductor (MEIC) ensure the long-term stability of the SCP modulation layer. With this layer, the SCP@Li symmetric cell maintains a low overpotential for 750 cycles even at a high current density of 5 mA cm-2. Additionally, the LiFePO4//SCP@Li full cell achieves an imperceptible capacity decay of 0.03% per cycle for 800 cycles at 0.5 C.

However, the impact of cationic and anionic moieties within zwitterions on enhancing the performance of AZIBs remains poorly understood. Herein, three zwitterions, namely carboxybetaine methacrylate (CBMA), sulfobetaine methacrylate (SBMA), and 2-methacryloyloxyethyl phosphorylcholine (MPC), were selected as additives to investigate their different action mechanisms in AZIBs. All three zwitterions have the same quaternary ammonium as the positively charged group, but having different negatively charged segments, i.e., carboxylate, sulfonate, and phosphate for CBMA, SBMA, and MPC, respectively. By systematical electrochemical analysis, these zwitterions all contribute to enhanced cycling life of Zn anode, with MPC having the most pronounced effect, which can be attributed to the synergistic effect of positively quaternary ammonium group and unique negatively phosphate groups. As a result, the Zn//Zn cell with MPC as additive in ZnSO<sub>4</sub> electrolyte exhibits an ultralong lifespan over 5000 h. This work proposes new insights to the future development of multifunctional zwitterionic additives for remarkably stable AZIBs.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01826-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
