SPAN Cathode Material
SPAN material is a cathode material for lithium-sulfur batteries, synthesized by sintering and reacting polyacrylonitrile (PAN) with elemental sulfur at 200–450°C. It appears as a dark brown powder with a sulfur content of approximately 45–50%, exhibiting excellent electrochemical stability and electrical conductivity.
SSPN High-Sulfur Composite Cathode Material
SSPN employs a high‑sulfur composite design, enabling greater capacity and stronger energy output—making it well suited for high‑specific‑energy lithium–sulfur battery systems.
Mg-Li Alloy Three-Dimensional Current Collector
The Mg–Li Alloy 3D Current Collector is an ultra-lightweight, high-conductivity metallic scaffold engineered for lithium–sulfur, lithium–metal, and solid-state batteries.This addresses the fundamental limitation of lithium metal anodes by providing a dedicated current collector that enables long cycle life.
Sulfurized Polymeric Solid Electrolyte(SPSE)
This product is a novel solid electrolyte tailored for high-performance battery applications. It features low interfacial impedance, effective suppression of lithium dendrite growth and polysulfide shuttling, high safety, excellent film-forming property and tunable performance. With great electrode compatibility, it can synergistically enhance the energy density and cycle lifespan of batteries.
