Analytical and Measuring Instruments for Rechargeable Lithium Ion Batteries

rechargeable-lithium-ion-battery.png

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.

Featured Applications

Positive Electrode

Battery 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.

Negative Electrode

Battery Negative Electrode

As the market for lithium-ion battery for automotive use expands, the challenge is to further improve energy density while reducing costs. As a component, the negative electrode plays an important role together with the positive electrode.

 

Separator

Battery 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.

 

Electrolyte Solution

Battery 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.

 

Battery Cell

Battery Cell

Lithium-ion battery are used in a variety of fields and applications, and it is important to analyze defective products, compare good products and defective products, compare before and after charging and discharging, observe structural changes inside cells in cycle tests, and evaluate gas components.
