Shimadzu SMX-225CT scanners enable precise nondestructive imaging of internal battery components.
Shimadzu subsidiary Kratos Analytical offers X-ray Photoelectron Spectroscopy instruments for advanced surface and electrochemical investigations.
Analytical and Measuring Instruments for Rechargeable Lithium Ion Batteries
The lithium-ion rechargeable battery is a relatively new type of battery that was first used in the early 1990s. With their high voltage and high energy density, these batteries are widely used for consumer electronics applications, such as mobile phones and laptop computers. Due to enhanced consumer concerns for the environment and fuel savings, the automobile industry has also been developing these batteries for hybrid vehicle (HV) and electric vehicle (EV) applications, which should lead to enhanced output, efficiency, and performance. As a leading manufacturer of a broad range of analytical and testing instruments, Shimadzu provides a variety of solutions that contribute to research, development, and quality control of lithium-ion rechargeable batteries as they become more widely used in consumer electronics and eco-cars.
Rechargeable Lithium-Ion Battery Evaluation - Application Notebook
Lithium-ion batteries are used widely in household electrical appliances such as cell phones and laptop computers. A considerable increase in demand for lithium-ion batteries is predicted in the transportation sector, where they will be used in aeroplanes, hybrid vehicles, and electric vehicles. These applications will require an increase in the power density, efficiency, lifespan, and stability of these batteries. Lithium-ion batteries are composed of a number of parts, including a cathode, anode, electrolyte, and separator. Increasing the performance of lithium-ion batteries will require detailed investigation and analysis of the properties of each of these components, and of the battery as a whole, by instrument analysis.
