Summary: The complex microstructure of the electrode greatly affects the performance of lithium-ion batteries (LIBs). The microporosity of the carbon binder domain (CBD) has been studied for the first time, revealing its influence on battery performance. The battery's specific capacity improves as the microporosity of the CBD phase increases.

Summary: We report a wet-chemical process to obtain binder-free anodes for lithium-ion batteries using electrochemical deposition, anodization, and electropolymerization. The resulting SnO2@PANI electrodes demonstrate good specific capacity, capacity retention, and charge transfer resistance, attributed to their large surface area, high electrical conductivity, and effective reduction of volume expansion.

Summary: We synthesized crosslinked polyimides by condensation polymerization between 3,4,9,10-perylenetetracarboxylic dianhydride and 1,2-ethanediamine in the presence of a trifunctional crosslinker of diethylenetriamine. The crosslinked polyimides exhibited a porous structure with a high surface area. When used as cathode materials in lithium metal half-cells, the crosslinked polyimides showed a high discharge capacity of 160.3 mA h g-1 at a current density of 30 mA g-1, and the assembled lithium-ion batteries retained 77% capacity after 2000 cycles at a current density of 150 mA g-1, surpassing the performance of batteries with linear polyimides.

Summary: In this study, a thermoplastic intrinsic self-healing polymer (TISP) binder is proposed to improve the mechanical damage and cycle performance of lithium-ion batteries. The TISP binder has properties such as low glass transition temperature, amorphous structure, and low cross-link density, which enhance structural recovery and strong adhesion. Additionally, the decomposition of the TISP reduces side reactions under high voltage conditions. Experimental results show that the LiCoO2 electrode battery using the TISP binder retains 86.5% capacity after 349 cycles at 4.5 V, and heating the damaged electrode recovers 96% of the capacity compared to an undamaged battery.
