However, the widespread adoption of Li–S batteries has been impeded by challenges such as the diffusion of long-chain polysulfides and the formation of lithium dendrites when organic liquid electrolytes. To address these problems, a composite polymer electrolyte reinforced with Li6.28La3Al0.24Zr2O12 nanofiber (LLAZO NF) was developed. This electrolyte, featuring a garnet nanofiber filler within a PEO-based polymer system, exhibited superior ionic conductivity. The well-interconnected organic–inorganic network facilitated rapid and uninterrupted pathways for lithium-ion conduction, achieving a high Li-ion transference number. The incorporation of LLAZO NFs not only enhanced the electrochemical stability and mechanical properties of the composite polymer electrolyte, effectively mitigating lithium dendrite formation, but also contributed to the suppression of polysulfide diffusion during cycling. As a result, the all-solid-state Li–S battery utilizing this garnet-type composite polymer electrolyte demonstrated robust cycling stability and excellent rate performance at room temperature.}, journal={ACS APPLIED ENERGY MATERIALS}, author={Cheng, Hui and Yan, Chaoyi and Chang, Liang and Dirican, Mahmut and Orenstein, Raphael and Zhang, Xiangwu}, year={2024}, month={Apr} }

Increasing the polymer thickness can improve the folding resistance but it decreases the touch sensitivity. Thus, fabricating highly foldable and supersensitive polymer cover windows is still challenging. Here, by incorporating cellulose nanocrystals (CNCs) and zirconia (ZrO2) into colorless polyimide (CPI), we developed a highly foldable and supersensitive hybrid cover window. Inspired by the theory of elasticity, we added rigid CNCs into CPI to improve the elastic modulus and hence the foldability. ZrO2 was introduced to improve dielectric properties, which leads to improved touch sensitivity. After these modifications, the elastic modulus of the cover windows was increased from 1432 to 2221 MPa, whereas its dielectric constant was increased from 2.95 to 3.46 (@1 × 106 Hz), resulting in significantly enhanced foldability and sensitivity. Meanwhile, because of the nano size of CNCs and ZrO2, the hybrid cover windows exhibit excellent optical properties with the transmittance of ∼88.1%@550 nm and haze of 2.39%.

Here, by using cellulose nanocrystals (CNCs) as a nanocarrier to load CUR and AuNPs simultaneously, we developed a hybrid nanoparticle as a codrug delivery system to enhance the low and stand-alone therapeutic effects of CUR. Aided with the encapsulation of β-cyclodextrin (βCD), both the solubility and the stability of CUR are greatly enhanced (solubility increased from 0.89 to 131.7 μg/mL). Owing to the unique rod-like morphology of CNCs, the system exhibits an outstanding loading capacity of 31.4 μg/mg. Under the heat effects of coloaded AuNPs, the system demonstrates a high release rate of 77.63%.

However, current cellulose-related substrates are incapable to ensure both high performance and low-cost requirements. Here, we developed high-performance, low-cost, and eco-friendly green composite substrates for flexible and green electronics. The green composite substrates were constructed by two natural components of lignin and nanocellulose derived from wood. Through pretreatments of dialysis fraction and epoxidation modification, lignin's heterogeneous structure and moderate surface activity were remarkably improved. The two components exhibit excellent compatibility, and the regenerated substrates demonstrate plastic-like high performance and paper-like degradability, showing low surface roughness (4.68 nm), high ultimate tensile stress (146 MPa) and elastic modulus (16.16 GPa), high transmittance (59.57%@750 nm), and prominent thermal, electrical stability and flame retardancy. After lignin pretreatments, the ultimate tensile stress was vastly increased by 554%. And modified lignin can be added with an ultra-high loading amount (up to 50 wt%), which significantly reduces substrate cost. Consequently, RFID antennas were fabricated on these substrates, which demonstrate distinctive degradability.

High accessible surface, enriched surface N/O groups, and reduced fiber diameters endow the LUPCFs-based electrodes with an excellent specific capacitance of 289 F g−1. The reduction of fiber diameters remarkably improves the rate performance of the LUPCFs and leads to a low relaxation time constant of 0.37 s. The high specific capacitance of 162 F g−1 is maintained when the current density is increased from 0.1 to 20 A g−1. Besides, the fabricated LUPCFs show exceptional cycling stability in symmetrical supercapacitors, manifesting a promising application prospect in the next generation of supercapacitors.}, journal={JOURNAL OF COLLOID AND INTERFACE SCIENCE}, author={Ma, Chang and Wu, Liqiang and Dirican, Mahmut and Cheng, Hui and Li, Junjing and Song, Yan and Shi, Jingli and Zhang, Xiangwu}, year={2021}, month={Mar}, pages={412–422} }

The severity of battery fires is directly linked to the combustion behavior of battery components such as the separator and electrolyte which constitute the main combustible materials in the battery.

In this work, aiming to alleviate the battery separator's combustibility and preserve the electrochemical performance of lithium-ion batteries, we designed a novel low heat releasing composite separator by incorporating 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) into the polyacrylonitrile (PAN) matrix via electrospinning technique.

During centrifugal spinning, the polymer solution or polymer melt is ejected out of the rotating spinning head, and when the centrifugal force overcomes the surface tension of the polymer liquid material, the polymer jet undergoes a stretching process and is eventually deposited on the collector, forming solidified nanofibers.

An enhanced Li-S battery with [email protected]:3 separator delivered an initial capacity of 1499 mA h g−1 and a high reversible capacity of 808 mA h g−1 after 200 cycles at 0.2 C. Additionally, the Li-S cell with [email protected] separator also presented outstanding anti-self-discharge capacity even after 24 h resting.

In addition, cells using SiO2/PVDF hybrid membrane separators showed superior C-rate performance compared to those using commercial microporous PP membrane.}, journal={JOURNAL OF MEMBRANE SCIENCE}, author={Yanilmaz, Meltem and Lu, Yao and Dirican, Mahmut and Fu, Kun and Zhang, Xiangwu}, year={2014}, month={Apr}, pages={57–65} }
