“…Porosity is one of the most important factors to change electrode volume. By comparison of SEM pictures in the literature [26], the porosity of the HOPG electrode was smaller than that of the coke electrode. Then, there were increasing irreversible stresses on both of the membrane electrodes had with time.…”

“…Rosolen and Decker [26] used a laser-beam detector to study the influence of active grain morphology on electrode stress in three types of film carbon electrodes when Li-ions intercalated and de-intercalated in a three-electrode cell sealed in a rectangular solid optical box, the reference and counter electrodes of which were Li metal. Different stress evolution was found for three carbon electrodes with different active grain shapes.…”

“…Active grain morphologies such as grain shape and orientation affect electrode stress generation and evolution. Rosolen and Decker [26] studied the characterization of the strain sources in two types of highly oriented pyrolytic graphite (HOPG) and coke membrane electrodes. The scanning electron microscopy (SEM) images of carbon electrodes showed that the HOPG electrode grain was highly crystalline, and the coke electrode had a wrinkled surface.…”

Li-ion batteries experience mechanical stress evolution due in part to Li intercalation into and de-intercalation out of the electrodes, ultimately resulting in performance degradation. In situ measurements of electrode stress can be used to analyze stress generation factors, verify mechanical deformation models, and validate degradation mechanisms. They can also be embedded in Li-ion battery management systems when stress sensors are either implanted in electrodes or attached on battery surfaces. This paper reviews in situ measurement methods of electrode stress based on optical principles, including digital image correlation, curvature measurement, and fiber optical sensors. Their experimental setups, principles, and applications are described and contrasted. This literature review summarizes the current status of these stress measurement methods for battery electrodes and discusses recent developments and trends.

Materiais carbonaceos com diferentes estruturas são preparados da carbonização do bagaço da cana de açúcar. Os materiais obtidos são caracterizados utilizando-se microscopia de varredura eletrônica e técnicas eletroquímicas. Dependendo das condições de carbonização é possível obter fuligens ricas de partículas tipo flocos ou tipo colméia de abelha, cuja concentração tem grande influência sobre a armazenagem de lítio nos eletrodos. Para fuligens ricas de partículas do tipo colméia observa-se uma capacidade específica reversível da ordem de 310 mAh g -1. Os resultados sugerem que o bagaço da cana pode ser um percursor com potencial para o desenvolvimento de materiais anódicos para baterias de ions de lítio.Carbonaceous materials with different structures are prepared by carbonization of sugarcane bagasse. Depending on carbonization conditions, it is possible to obtain soot rich in flakes or in honeycomb-shaped micrometric particles, whose concentration has large influence on lithium storage into electrodes. The soot rich in honeycomb-shaped particles provides the best electrochemical performance, with a reversible specific capacity of 310 mAh g -1 . The results suggest that the sugarcane bagasse can be potentially used in the design of anodic materials for lithium ion batteries. Keywords: sugarcane, honeycomb carbon, lithium ion battery IntroductionLi-ion battery is an electrochemical cell with electrodes that can be prepared with several Li intercalation compounds. The electrochemical performance of electrodes consisting of these compounds is strongly controlled by the structural and electronic properties of the intercalation material.1,2 Over the last years several oxides, alloys, and carbons have been claimed for the preparation of Li-ion battery. LiCoO 2 and graphite with spheroid shape are the most commonly employed cathodic and anodic materials in commercial Li-ion batteries, respectively. This is because these two compounds, which respectively provide a practical specific reversible capacity of approximately 135 and 360 mAh g -1 , allow the preparation of electrodes with good mechanical properties, low electrochemical impedance, low ohmic drop and relative good thermal stability. They also withstand the pressure applied inside the cells during the preparation of the electrodes and resist the mechanical stress associated with the Li intercalation that takes place during volume changes and double-layer formation throughout electrical polarization.3 However, in the case of graphite, the control of structural properties in large-scale processing plants is not easy, specially when this 'plant' is natural. The genesis of graphite mine can undergo alterations during its extraction. For example, the dimension of crystallites is a parameter that has implications in the preparation of electrode and in the kinetics of lithium intercalation, as well as in the value of specific capacity Here we present an investigation of Li electrointercalation in carbonaceous materials prepared from abundant, inexpensive biomass (less...
