Electrode material
Microscopic Composition Analysis of Powder Particle Cross Section (Gradient Material Process Optimization) - Analyzing the Uniform Distribution, Impurity Sources, and Distribution of Internal Components in Particles

Electrode material
Analysis of crystal orientation distribution of electrode material particles and optimization of battery performance

Electrode material
Powder particle cross-sectional analysis - coating thickness, type, electrode material doping process

Electrode material
Powder particle cross-sectional analysis - XPS erosion can be used to evaluate the coating and doping uniformity of a large number of materials

Electrode material
Analysis of Defect Distribution in Electrode Materials (Lithium Nickel Mixed Discharge Position)

cell
Observation of battery electrode cross-section and analysis of coating uniformity - (can quantitatively evaluate the distribution uniformity of the electrode as a whole or a single specific additive)
Example 1: Uneven distribution of carbon nanotubes leads to poor battery performance. Through software automatic analysis and intelligent image recognition statistical technology, two-dimensional images can be converted into numerical values to evaluate the microstructure of the material.

Example 2: Analysis of the selection and proportioning of electrode materials inside the electrode sheet of the battery cell.

Example 3: Determine the selection and ratio of conductive agent materials in the electrode pieces of the battery cell through microstructure and composition matching analysis.

cell
Modification and observation of SEI film on battery cell polarizer - electrolyte/electrode material compatibility testing

Analysis of battery gas composition
When the electrolyte and electrode materials do not match, qualitative analysis of the gas is performed by gas chromatography, and quantitative analysis of the gas is performed by mass spectrometry.

When the water content of the battery exceeds the standard, the battery will swell when stored at high temperatures. GC can be used to detect whether the battery bloating is caused by the excessive water content of the product.

In situ analysis of batteries
The deterioration of the battery before and after charging and discharging - by observing the composition and morphology information of parasitic reactions at the electrode material interface, the cause of battery performance degradation can be identified.

By observing the changes in morphological information during the charging and discharging process of electrode materials, the fundamental cause of battery performance degradation can be identified.
