Why Electrode Microstructure Architecture Determines Cell Performance

AION Engineering INC In lithium-ion batteries, electrode performance is governed not only by material chemistry but by the three-dimensional microstructure formed by particles, pores, binder, and conductive additives. Before production begins, this microstructure already defines how ions and electrons will move through the electrode. Once manufacturing starts, many of these structural characteristics can no longer … Read more

Variability in Battery Pack Capacity

statistical variation in pack capacity

In school, we learn that the voltage across circuit components in parallel is the same, and the current is split between them according to their resistances. For components in series, the current through each is equal and the voltage drops off. In a simple model, the total capacity of a battery pack with cells in … Read more
