As lithium battery technology improves, it becomes more important to have solid polymer electrolyte dividers that work better. The objective of this study is to enhance the efficiency of solid polymer electrolyte separators in lithium batteries. This research aims to expand the limits of innovation in hybrid separator development by utilizing empty palm fruit bunches (OPFEB) as a plentiful source of cellulose acetate. This approach enhances ion transfer by increasing the number of pores in the separator. However, there are challenges to achieving the desired levels of optimal ionic conductivity. In order to address these constraints, this study presents a novel Al2O3-PAA inert ceramic oxide coating treatment that is applied to the separator by a spin coating technique. An electron microscope was utilized to observe the pore structure of the separator. Additionally, the separator underwent physical, mechanical, thermal, and cyclic voltammetry tests. The findings of this research indicate a significant increase in the physical properties, particularly the porosity and mechanical strength. The thermal shrinkage of the Al2O3-PAA coated separator is below 10% when exposed to a temperature of 140 oC for 30 minutes. The Cyclic Voltammetry test results demonstrate a pronounced loop curve, indicating an improvement in the ionic conductivity of the Al2O3-PAA coated separator. The findings of this study provide a method to enhance the efficiency of separator performance at high temperatures while maintaining safety and long battery life.

The burgeoning field of energy storage battery innovation has sparked a relentless pursuit of high‐capacity anode materials to meet the escalating demand for improved energy density. Typically, these materials for batteries experience significant volume changes during cycles, which severely test the structural integrity and lifespan of electrode configurations. High‐performance binders have emerged as a critical component in addressing this challenge. Although they represent a small proportion of the battery's composition, binders play a pivotal role in enhancing electrochemical efficiency, safety, and cost‐effectiveness of batteries. The advancement of high‐capacity anode materials has rendered traditional binders inadequate, prompting the development of functional binders that are increasingly being refined to meet these requirements. This article began by outlining the role and requirements of binders within electrodes, examining cutting‐edge characterization methodologies, and discussing the “structure‐function” paradigm that underpins binder selection. It then showcased the research advancements in identifying suitable binders for high‐capacity anode materials, including silicon (Si), phosphorus (P), tin (Sn), antimony (Sb), and germanium (Ge). In summary, the article contemplated the future direction of binder development and application in high‐capacity electrode materials. The aim is to facilitate the progression of high‐performance, high‐capacity anodes, thereby accelerating the development of high‐energy‐density lithium‐ion and sodium‐ion batteries.
