Next-generation lithium-sulfur battery technology.
Brighsun New Energy is dedicated to advancing Li-S and solid-state battery chemistry — pushing the limits of energy density, lifecycle and safety.
Energy density vs. conventional lithium-ion
Capacity retention at 2C cycling
Retention under 5C fast-charge cycling
Engineered from the molecule up.
After more than a decade of intensive R&D, Brighsun has achieved breakthroughs across every layer of the cell — cathode, electrolyte, separator and anode — unlocking performance that conventional lithium-ion cannot reach.
Our patents cover sulfur composite cathodes, solid-state Li-S nanoparticles and polysulfide-suppression architectures, supporting both high-energy and high-power application profiles.
Inside the cell
From 18650 cylindrical cells to prismatic modules, validated by SEM imaging and long-cycle testing in our laboratories.
Core innovations
Li-S cathode architecture
Proprietary sulfur composite cathode with engineered porosity, dramatically extending active material utilisation.
Solid-state composite nanoparticles
Solid-state lithium-sulfur composite nanoparticle systems with stabilised interfaces.
Polysulfide suppression
Multi-layer electrolyte and separator design that suppresses the polysulfide shuttle — the long-standing barrier of Li-S chemistry.
Dendrite-free anode
Engineered lithium-metal anode chemistry that suppresses dendrite formation under high-rate cycling.
Custom electrolyte & separator
Proprietary electrolyte additives and functional separator membranes developed in-house.
Scalable manufacturing
Process engineering designed for transferability to gigawatt-scale production lines.
