Conclusions In this work, the water-soluble binder with 3D network structure was successfully synthesized and employed in the silicon anode for lithium-ion batteries. The 3D network structure was formed through hydrogen bonding between polar groups. Compared to linear binders, the 3D network binders have higher bonding strength.
In order to analyze the influence of the binder on the battery cycling process, we characterized the mechanical properties and the morphology of the electrodes before and after cycling. The nano-indentation test was used to test the mechanical properties of different binders with a fixed pressure value of 2 mN during the test.
The binder plays a crucial role in maintaining the integrity and enhancing the conductivity of the electrode, although it accounts for a small weight fraction in the entire electrode. However, the conventional binder used in lithium–sulfur (Li–S) batteries fails to effectively tackle the challenges posed by
In this work, we first design a new binder system by employing a Multifunctional Network Binder (MNB) to complement the inherent weaknesses of Li-PAA binder and improve the electrochemical performances of Si-based electrode.
This network binder was capable of effectively preventing polysulfides within the electrode from shuttling and, consequently, improved electrochemical performance. A remarkably high sulfur loading of 19.8 mg cm −2 and an ultrahigh areal capacity of 26.4 mA h cm −2 were achieved as a result of the robust mechanical properties of the network binder.
This study paves a new way for obtaining high-energy-density batteries by the simple application of robust network biopolymer binders that are inherently low-cost and environmentally friendly.
