Test, analyse et inspection des batteries et des piles à combustible

Testing, Analysis and Inspection of Batteries and Fuel Cells

Les progrès réalisés dans le domaine des piles à combustible et des batteries permettent de créer de nombreux véhicules électriques. Shimadzu fabrique une gamme complète d'instruments permettant de caractériser la composition et le comportement thermique/mécanique des membranes, des électrolytes et des électrodes des cellules de batterie.

Les scanners Shimadzu SMX-225CT permettent une imagerie non destructive précise des composants internes de la batterie.

Kratos Analytical , filiale de Shimadzu, propose des instruments de spectroscopie photoélectronique à rayons X pour des études de surface et électrochimiques avancées.

Applications

Battery Positive Electrode

Positive Electrode

The positive electrode is an important component that influences the performance of lithium-ion battery. Material development is underway to improve the high energy density and durability against charge/discharge cycles. In order to reduce the cost of battery and ensure a stable supply, the flow of cobalt-free positive electrode active materials is advancing.

Battery Separator

Separator

Separator is an important component that prevents short circuits between positive and negative electrodes, and at the same time facilitates the smooth passage of lithium ions. In addition to high safety, high energy density, high input/output, and low cost are required, and performance evaluation from various viewpoints is important.

Battery Electrolyte Solution​

Electrolyte Solution

The electrolytes and solvents that make up the electrolyte solution must-have characteristics such as oxidation and reduction resistance during charge and discharge, thermal and chemical stability, and ionic conductivity, and must be capable of producing high-quality SEI coatings. It is also important to analyze electrolyte solution components in order to evaluate battery performance because the composition is modified by battery reaction.
