Technical Information: Release of 'Distribution Evaluation of Powder Particle Surfaces by TOF-SIMS' and 3 other items.

Evaluation of the components distributed on the surface of a single particle of powder is possible.

We will introduce a case where a sheet coated with graphite negative electrode particles used in lithium-ion secondary batteries was analyzed using TOF-SIMS. It was confirmed that graphite and PVDF are distributed on the surface of a single powder particle. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) is a method suitable for qualitative analysis and imaging of organic and inorganic substances on surfaces from the mass spectrum of secondary ions. It is effective for evaluating the distribution of minute foreign substances and stains due to its high resolution. Measurement method: TOF-SIMS Product field: Secondary batteries Analysis purpose: Composition distribution evaluation For more details, please download the materials or contact us.

• Contract Analysis

Evaluation of gas release components from organic films and temperature dependence assessment are possible with TDS.

TDS is a method that heats samples in high vacuum (1E-7 Pa) and investigates the gases released from the samples using a mass spectrometer. Since it is a vacuum system, it is not suitable for the large release of organic substances, but it can be evaluated by adjusting the sample amount. Below is an example of TDS analysis conducted on a resist film. Desorption gases originating from the resist film, such as organic substances, water, H2S, and SO2, were detected. It was also found that the desorption temperatures varied depending on the components.

• Contract Analysis

You can confirm the changes in degassing due to differences in the baking temperature of the sample using TDS.

TDS can evaluate the temperature dependence of the desorption of inorganic and organic gases that are released with increasing temperature. Therefore, it is effective for assessing the degassing of samples based on the baking temperature. The results of TDS analysis after baking the resist film at 50°C and 200°C are shown. It was confirmed that the degassing peaks detected up to 200°C after "baking at 50°C" were not detected after "baking at 200°C."

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
