CT-1Plus titrator for measuring residual alkali content on the surface of positive electrode materials

In the arena of lithium-ion battery performance, positive electrode materials play a crucial "heart" role. The residual alkali content on its surface is the core key indicator for measuring the health of this' heart '.

How to quickly and accurately monitor and reduce this indicator has become an urgent quality control problem for many positive electrode material manufacturers and battery manufacturers. The traditional manual titration method is limited by factors such as human endpoint judgment, cumbersome operation steps, and poor data stability, making it difficult to meet the strict requirements of modern production for efficiency and accuracy.

The way to break through: fully automatic potentiometric titration technology

Faced with the pain points in this industry, the CT-1Plus automatic potentiometric titrator has emerged. With its excellent precision and efficient automated process, it provides a reliable standardized application solution for the determination of residual alkali content on the surface of positive electrode materials.

Why chooseCT-1Plus titrator for measuring residual alkali content on the surface of positive electrode materialsCore technological advantages revealed

1. Intelligent endpoint determination, bidding farewell to human error

CT-1Plus adopts a differential determination endpoint mode, which captures the small pH changes of the solution during the titration process in real time with a high-sensitivity pH composite electrode. The instrument intelligently identifies titration jump points, eliminating the subjectivity and uncertainty of traditional visual judgment, and making each endpoint data objective and true.

2. Micro precision titration with high data resolution

The high-precision measuring tube equipped with the instrument can achieve a minimum titration volume increment of 20 μ L. When facing samples with low residual alkali content, this micro upgraded fine control ability can clearly capture changes in the titration curve, ensuring high resolution and accuracy of the test results.

3. Standardized processes and excellent repeatability

The standard operating procedure (SOP) for CT-1Plus ensures consistency throughout the entire process from sample preparation to result output, from water extraction, stirring and filtration to titration on the machine. Users only need to set the parameters (such as stirring speed of 200 and titration interval of 1000ms) to obtain reliable data with good inter batch repeatability, providing a solid basis for process optimization.

4. Efficient and convenient, greatly improving quality inspection efficiency

The entire titration process is automated and does not require personnel to be on duty. Single sample testing only takes a few minutes, greatly freeing up laboratory manpower and enabling analysts to focus more on data interpretation and process decision-making, adapting to the fast pace of quality control on the production line.

Practical verification: Data speaks for itself, excellent performance

We conducted parallel testing on a certain positive electrode material in a strictly controlled temperature and humidity environment (25 ° C, 35%):

Sample size: 5.0133g&5.1039g

Titrant: 0.1mol/L hydrochloric acid standard solution

Test results: The residual alkali content is 0.0344% and 0.0330% respectively, with an average of 0.0337%.

The two sets of data are highly consistent, with an accurate result of an average value of 0.0337%. This not only clearly defines the quality level of the batch of products, but also fully verifies the excellent repeatability and reliability of the CT-1Plus method.

Empowering industries: from precise measurement to quality upgrading

introduceCT-1Plus titrator for measuring residual alkali content on the surface of positive electrode materialsThis means that a solid technical barrier has been established for the quality control of positive electrode materials:
