Although the aqueous-based cathode slurry is easy to be transferred to the current coating technology without extra cost, the sacrifice of capacity and cycle stability is not acceptable for battery production. Solvent-free manufacturing emerges as an effective method to skip the drying process and avoid the organic solvent.
The results indicated that ISP led to notable improvements in porosity, adhesion, and rate performance compared to the baseline cathodes. This work elucidates the microstructural changes induced by ISP in lithium-ion battery cathodes and high-lights the technology’s promise for advancing battery manufacturing.
The limited resources and space in the laboratory restrict the research activity on the battery system. Therefore, more collaboration between academic researchers and battery manufacturers could help the development of battery systems. Recycling becomes an inevitable topic with the surging of LIB manufacturing capacity.
The high operating temperature (up to 80°C) of LIB especially the power battery for automotive can result in an increase of connection resistance and temperature variation, which will cause thermal expansion or even thermal fatigue and damage the tab joint (Brand et al., 2013; Zhao et al., 2014).
Currently, the formation and aging steps in the Li-ion battery manufacturing process are the greatest bottleneck in terms of time and materials due to extended holds required for adequate wetting as well as a finite number of cycling chan-nels available for formation.
Lithium-ion batteries (LIBs) have become one of the main energy storage solutions in modern society. The application fields and market share of LIBs have increased rapidly and continue to show a steady rising trend. The research on LIB materials has scored tremendous achievements.

Introduction to Lithium–Ion Batteries | SpringerLink
Lithium–ion batteries (LIBs) are composed of one negative electrode, one positive electrode, a separator, and a liquid electrolyte battery. The preparation of an electrode is necessary to test electrochemically new materials (see Fig. 1.1a). As the first active material and binder are mixed together, solvent is added to adjust the final viscosity to prepare the electrode.
