08-09-2016· In this work, we have introduced the particle size as a distributed parameter into a single particle electrode model for graphite electrodes to study the effect of the particle size distribution (PSD) on performance. The presented results show the impact of the shape and scale of the PSD on electrode performance.

varioussizes is usuallyneglected. Thedifferent particle sizes, for example,ofthe active material particles, yield ahighly heterogeneous system.This is usually quantified by the parti-cle size distribution (PSD). In this work, the impactofthe PSD on the performance and its degradation of graphite electrodes is analyzed with amodel-based approach.

Graphite Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

Particle-size distribution Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
