Design of experiments for optimizing the calendering process in Li-ion battery manufacturing

چکیده
Calendering is a key yet complex manufacturing process that has varied effects on the Li-ion battery cell performance. Finding optimal compaction can require many experiments if using traditional one-factor-at-a-time method, which would be both and resource intensive. Design of Experiments (DoE) coupled with modeling via multiple linear regression (MLR) are used in this study to better understand electrode calendering. The factors studied report rolling temperature, post-calendered porosity, mass loading NMC622 their effect electrochemical exact combinations these will create an information-rich data set prepared DoE. MLR then extract information form understanding how each factor (individually combination other ones) affect performance cells. Via approach, physical statistical significance quantified. Furthermore, models determine result Overall, highlights use DoE highlight most important regions design space conduct while model system (calendering).

Design and Analysis of New Level Shifter With Gate Driver for Li-Ion Battery Charger in 180nm CMOS Technology
In this work, the design and analysis of new Level Shifter with Gate Driver for Li-Ion battery charger is proposed for high speed and low area in 180nm CMOS technology. The new proposed level shifter is used to raise the voltage level and significantly reduces transfer delay 1.3ns (transfer delay of conventional level shifter) to 0.15ns with the same input signal. Also, the level shifter with g...
متن کاملSimplified Lithium-Ion (Li+) Battery-Charger Testing - Reference Design - Maxim
Because the charging process for Li+ batteries can take an hour or longer, testing a Li+ battery charger using its natural load (i.e., a battery) is time consuming and inconvenient. This application note presents a simple circuit for simulating the behavior of a Li+ battery, thus providing a more convenient method for testing Li+ battery chargers than using real batteries. A similar version of ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
