Auf den Spuren von Lithium im Mikrometerbereich

Lithium-Ionen-Batterien (Li) werden aufgrund ihrer herausragenden Energiedichte und geringen Masse für eine Vielzahl von Energiespeicheranwendungen eingesetzt. Es besteht weiterhin großes Potential zur Verbesserung der Kapazität und der Effizienz dieser Energiematerialien durch die Optimierung der verwendeten Komponenten und Materialien. Insbesondere durch den Mangel an geeigneten Charakterisierungstechniken auf der Mikro- und Nanoebene, sind die Abbaumechanismen und Strukturentwicklungen noch nicht ausreichend erforscht.

Capturing low-dose images, in-situ video, and diffraction data with the Metro counting camera

Gatan’s latest counting camera, Metro, produces excellent results at low dose rates and low to moderate accelerating voltages (60 – 200 kV). In this webinar, we show images from zeolites and MOFs, as well as diffraction patterns and 4D STEM datasets from 2D materials. We demonstrate the in-situ capabilities of the camera, which can capture video datasets at up to 41 frames per second at full 2k x 2k resolution.

3DED: A brief overview of data collection, and data analysis

The determination of precise atomic arrangements in a crystal material is the key to understanding the structure-property relationship, and it will further facilitate synthetic designs of new materials. In the past decades, the structure determination of submicron/nanometer crystals has been achieved via 3D electron diffraction (3DED). This technique is also known as continuous rotational electron diffraction (CRED) or MicroED (microcrystal electron diffraction.

DualEELS:对低能损电子能量损失谱数据校正的重要性

Nanoscale characterization of Li metal batteries enabled by cryogenic lift-out

Developing methods for electron-transparent specimens without inducing artifacts has become significantly important for the high-resolution characterization of battery materials. During this webinar, we introduced our recent approach (cryogenic-lift-out) to generate lamellae with cryogenic ion microscopy and talked about the effects of xenon ion beam on lithium metal batteries through the usage of cryogenic (S)TEM. We also showed the capability of the Metro direct detection counting camera to pull out the diffraction information that helps to identify the ion beam effect.
