Summary: We study the effects of carboxymethyl cellulose (CMC) on slurry dispersion in the anode preparation process. CMC plays multiple roles as a dispersant, thickener, and gelling agent depending on its content. The adsorption selectivity of CMC for carbon black and graphite particles is significantly affected by the mixing sequence with CMC when its content is lower than the optimum graft density. However, at higher CMC content, the slurry dispersion is less affected by the mixing sequence as both particles are eventually adsorbed and saturated.

Summary: Researchers have developed a water-soluble binder by integrating carboxymethyl cellulose (CMC) with polydopamine (PDA) to alleviate the volume effect of silicon microparticles (SiMPs) in lithium-ion batteries (LIBs). The Si@CMC-10% PDA electrodes show excellent cycling stability and rate performance, and the full cells composed of Si@CMC-10% PDA anodes and lithium iron phosphate (LFP) cathodes have high capacity retention. Therefore, this binder has significant potential for practical applications in LIBs.

Summary: Polysaccharides, such as cellulose sulfate lithium (CSL) with strong adhesion, are synthesized and used as binders for LiFePO4 (LFP) cathode. Compared to conventional polyvinylidene difluoride (PVDF) binder, LFP cathode using CSL (LFP-CSL) exhibits lower polarization and better rate performance due to higher lithium-ion conductivity. CSL binder also maintains the integrity of the LFP cathode structure during cycling, resulting in a discharge capacity of 133.4 mAh g(-1) and remarkable cycle stability after 300 cycles at 1C.

Summary: Two types of water-soluble carboxymethyl chitosan with different degrees of substitution were synthesized and used to assemble high-performance cathodes in lithium-nickel-manganese oxide (LNMO) batteries. The water-soluble O-CCTS provided abundant hydrogen bonding and chelation with metal ions, resulting in better wrapping and uniform coating of the cathode material on the electrode sheets. The O-CCTS-LNMO cathode exhibited higher discharge capacity and better impedance and cyclic performance compared to O,N-CCTS-LNMO and PVDF-LNMO.

Summary: In this study, a porous membrane based on lignin-containing cellulose nanofibers (LCNFs) was designed to overcome the drawbacks of traditional polyolefin separator, such as non-degradation and poor wettability with the electrolyte. The prepared membrane exhibited high electrolyte uptake and ionic conductivity, and showed promising application potential in high-energy LIBs. Moreover, the low cost and biodegradability of the LCNF membrane made from unbleached pulp can significantly reduce environmental pollution of LIBs. This research provides an efficient and low-cost method to fabricate a membrane with good biodegradability and high electrochemical performance for LIBs.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
