Tongling PPS (polyphenylene sulfide) pore - free solid - state separator has high ion selectivity. By controlling crystallinity and sulfur - site ion selectivity precisely, it suppresses lithium dendrite growth via homogenized electrode electric fields and ion rectification effects, and maintains sulfide electrolyte and lithium ion diffusion coefficients. Its dense structure cuts electrolyte uptake by 90% compared to traditional separators, weakening flammability. The PPS material keeps a dense, zero - shrinkage structure at 250°C, blocking the cathode - to - anode oxygen release pathway, and eliminating short - circuit risks above 130°C and lithium - oxygen thermal runaway risks. Meanwhile, this product has passed the needle-puncture and hot box tests and obtained the relevant certificates. This separator overcomes the traditional limitations where ion selectivity, rectification, uniform electrodeposition, and transport rate restrict each other. With high selectivity, its conductivity reaches 0.3 mS/cm, and when maintaining interfacial stability, the ion transference number is ≥0.8. It resolves the “high areal capacity requirements exacerbating structural non - uniformity degradation” contradiction in dry electrodes. Through a multi - level graded particle system design and coordinated dry - process parameter optimization, it overcomes bottlenecks in high - nickel or lithium - rich manganese thick electrodes, enhancing the energy density and cycle life of high areal capacity (5 mAh/cm²) electrodes. The Tongling PPS pore - free dense separator establishes a “thermal shrinkage suppression — dendrite growth barrier — blocking cathode oxygen diffusion” multi - level protection model, solving the thermomechanical - chemical multi - field coupling conflict of traditional separators, improving thermal stability and safety, and ensuring the production of high - specific - energy, high - safety lithium metal batteries.

  • 产品描述
  • Tongling PPS's poreless dense diaphragm aids lithium batteries in breaking through 500 Wh/kg, forming high-safety, high-specific-energy lithium metal battery products, promoting energy storage from an 'auxiliary system' to a 'core enabling technology,' and achieving the following breakthroughs across various fields:

    1. In the low-altitude economic sector, drone single-flight endurance is increased to 3 hours, AI multispectral payloads achieve centimeter-level operational accuracy, and combined with supercapacitors and other power battery packs in a 'low-altitude charging corridor,' supporting a 200 km long-range logistics network.

    2. In transportation, a 2000 kWh energy pack combined with power-type energy storage devices forms a peak energy system, enabling electric heavy trucks to achieve 800 km range and 30-minute fast charging.

    3. In the military industry field, a 50 MW-class pulsed power supply system on ships ensures continuous operation of electromagnetic weapons, while simultaneously supporting 72-hour extreme cold combat for individual exoskeletons.

    4. In robotics, breakthrough integration of liquid metal joint drives allows miniature nanosurgery robots to achieve 30-day endurance, and disaster relief equipment penetration power is increased threefold。

    5. In electric aviation, achieving eTVOL 800 km direct flight, all-electric regional aircraft range surpasses 2000 km with zero carbon emissions, and deep space exploration endurance is extended to 15 years。

    6. Consuming electric field, portable store energy set (power bank/outdoor energy) through "high-energy-density + low cost" features enhance the volumetric energy density while strengthening thermal runaway protection, meeting the dual requirements of safety and portability for consumer-grade products.

    7. In bio-integrated wearable devices have extremely potential, there is hope to make heart pacemaker volume be reduced by 80%, and brain-computer interface response time reaches 10 ms.

    8. In the future support smart photovoltaic clothing to achieve year-round self-power supply and vital signs regulation, forming an energy revolution ecosystem of collaborative innovation in 'military-civil-medical' applications.
