The optimization of the calendering process represents one key tasks for tuning lithium-ion battery performance. In this study, we present a systematic statistical-based study three main parameters (namely, applied pressure, roll temperature, and line speed) effect on porosity, electrode mechanical properties electronic conductivity. Our work goal is to understand how by changing parameters, ca...

In this study, Wedge statistical analysis tools were used to collect, collate, clean up, plot, and analyze several years of operational data from a commercial paper machine. The z-direction tensile (ZDT) Scott Bond tests chosen as representative fiber bond strength. After analyzing thousands parameters, the ones with most significant impact upon ZDT involved starch application method, penetrati...

The process chain of electrode production includes calendering as a crucial step to enhance the volumetric energy density well influence particle-pore-structure and simultaneously mechanical electrochemical properties coating. A further way improve is usage other materials with higher specific capacity, such silicon instead graphite active material for anodes. In this study, both opportunities,...

Understanding the formulation and manufacturing parameters that lead to higher energy density longevity is critical designing energy-dense graphite electrodes for battery applications. A limited dataset includes 27 different formulation, protocols, performance properties reported.

Abstract Prelithiation can boost the performance of lithium-ion batteries (LIBs). A cost-effective prelithiation strategy with high quality and industrial compatibility is urgently required. Herein we developed a roll-to-roll electrodeposition transfer-printing system for continuous LIB anodes. By calendering, pre-manufactured anodes could be fully transfer-printed onto electrodeposited lithium...
