Electrode tortuosity tester & diaphragm ion conductivity tester

Pole tortuosity tester

Main functions:

The pole sheet curvature tester is mainly used to measure the curvature of the battery pole sheet. Curvature is an important parameter to describe the complexity of pore structure in polar plates, which affects the penetration of electrolyte

Ion transport and battery performance.

How it works:

The tester usually calculates the deflection of the electrode plate by testing the ES（electrochemical impedance spectroscopy） of the electrode plate symmetrical battery. The E1S technology can provide information about the internal structure and dynamic process of the battery, thereby indirectly calculating the tortuosity of the pole plate.

Application scenario:

The pole sheet curvature tester is widely used in the research and development of secondary batteries such as lithium-ion batteries and sodium-ion batteries. By measuring the curvature of the pole plate, the structural design of the pole plate can be optimized, and the performance and stability of the battery can be improved.

Diaphragm ion conductivity tester

Main functions:

The separator ion conductivity tester is mainly used to measure the ion conductivity of the battery separator. Ionic conductivity is an important parameter to describe the ion conduction ability of the diaphragm, which directly affects the charge-discharge performance and cycle life of the battery.

How it works:

The tester calculates the ionic conductivity of the diaphragm by applying a certain voltage or current to both sides of the diaphragm and measuring the resulting current or voltage change. During the test, it is necessary to ensure that the temperature and humidity of the test environment are stable to obtain accurate test results.

Application scenario:

Diaphragm ion conductivity tester is also widely used in the research and development of lithium-ion batteries, sodium-ion batteries and other secondary batteries. By measuring the ionic conductivity of the diaphragm, the performance of the diaphragm can be evaluated, which provides an important basis for the material selection and modification of the diaphragm.
