Description

The 2340 trilayer separator is a high-strength microporous membrane engineered with a PP/PE/PP structure. Compared to thinner separators, it offers superior mechanical robustness and enhanced safety performance, making it ideal for demanding lithium-ion battery applications.

The outer polypropylene layers provide structural integrity and oxidation resistance, while the polyethylene core enables thermal shutdown functionality. This combination ensures reliable operation under high-temperature and high-load conditions.

Widely used in lithium-ion battery research laboratories, university research centers, and industrial R&D environments, this separator is suitable for both coin cell assembly and advanced battery prototyping.

Features

  • Trilayer PP/PE/PP structure for enhanced safety
  • Increased thickness (38μm) for mechanical strength
  • Thermal shutdown function (PE layer)
  • Zero transverse shrinkage reduces short-circuit risk
  • Uniform pore structure for stable ion transport
  • High oxidation resistance and thermal stability
