“…Unfortunately, at full lithiation a Si particle expands by 270% and this presents significant structural stability challenges at the level of the entire electrode. During lithiation, Si particles expand and encroach on each other and during delithiation, Si particles contract, which can result in detachment from surrounding electrical connections [90]. Such a drastic electrode morphology change can further contribute to capacity fading.…”

“…Total weight of EV battery packs can be reduced by replacing their primary component, i.e., the battery cells with cells made of novel materials that possess greater gravimetric capacity (mAh/g) or demonstrate a higher operating voltage than traditional active materials [53,54]. However, increase in gravimetric density of electrode materials cannot be scaled linearly to be reflected as nominal capacity of commercial battery cells due to the non-negligible weight of inactive cell components.…”

Application of Robust Design Methodology to Battery Packs for Electric Vehicles: Identification of Critical Technical Requirements for Modular Architecture

2018

Modularity-in-design of battery packs for electric vehicles (EVs) is crucial to offset their high manufacturing cost. However, inconsistencies in performance of EV battery packs can be introduced by various sources. Sources of variation affect their robustness. In this paper, parameter diagram, a value-based conceptual analysis approach, is applied to analyze these variations. Their interaction with customer requirements, i.e., ideal system output, are examined and critical engineering features for designing modular battery packs for EV applications are determined. Consequently, sources of variability, which have a detrimental effect on mass-producibility of EV battery packs, are identified and differentiated from the set of control factors. Theoretically, appropriate control level settings can minimize sensitivity of EV battery packs to the sources of variability. In view of this, strength of the relationship between ideal system response and various control factors is studied using a "house of quality" diagram. It is found that battery thermal management system and packaging architecture are the two most influential parameters having the largest effect on reliability of EV battery packs. More importantly, it is noted that heat transfer between adjacent battery modules cannot be eliminated. For successful implementation of modular architecture, it is, therefore, essential that mechanical modularity must be enabled via thermal modularity of EV battery packs.Keywords: P-diagram; house of quality; lightweight and compact battery packaging; ease of manufacturing/assembly; vehicle impact and crashworthiness; thermal reliability

“…The subsequent discharging step (I max = 140 µA, upper voltage limitation of 1 V) complements the formation procedure. The procedure applied ensured a homogeneous formation of the solid electrolyte interface (SEI) [16]. Furthermore, it represents a standardized sequence allowing for a reasonable comparison with the reference sample using silicon without any barrier material.…”
