Battery Diaphragm Gas Permeability Tester
The Battery Diaphragm Gas Permeability Tester is a precision instrument designed to evaluate the gas permeability of battery diaphragms and separators. It provides accurate, high-resolution measurements under controlled pressure conditions, enabling reliable assessment of materials used in battery production. The compact design and ease of operation make it suitable for laboratory and quality control environments.
Application
(1) Measuring gas permeability of battery diaphragms and separators in lithium-ion and other rechargeable batteries.
(2) Evaluating barrier performance of separator materials for battery safety and efficiency.
(3) Research and development of new diaphragm and separator materials.
(4) Quality control and inspection in battery manufacturing facilities.
(5) Laboratory testing for material science studies related to electrochemical devices.
(6) Comparing permeability of different separator types to guide material selection.
Standards
(1) GB/T 458 – Battery diaphragm gas permeability test method.
(2) ISO 536/2 – Paper and board determination of gas permeability.
(3) QB/T 1667 – Battery separator testing requirements.
(4) GB/T 23227 – Lithium-ion battery separator testing.
(5) ISO 2965 – Determination of gas permeability for thin films.
(6) YC/T 172 – Battery separator gas transmission test.
(7) GB/T 12655 – Testing of diaphragms for battery applications.
(8) GB/T 20042.7-2014 – Lithium-ion battery separator performance testing.
(9) GB/T 36363-2018 – Gas permeability test for battery diaphragm materials.
Features
(1) High-accuracy measurement of gas permeability (10–15000 s/100ml).
(2) Exceptional resolution (0.1 s/100ml) and pressure accuracy (0.0001 kPa).
(3) Multiple selectable pressure ranges: 5 kPa standard, 10 kPa and 20 kPa optional.
(4) Single-sample testing with secure sample holder.
(5) Compact, robust design suitable for laboratory environments.
(6) User-friendly interface for easy parameter setting and operation.
(7) Requires only clean air as a test gas.
(8) Provides reliable and repeatable results for quality control and R&D applications.
