Safer, longer-life lithium cells — built for Australia's energy future.
Cosmos Infinity is developing solid state lithium cells that replace flammable liquid electrolyte with a high-stability solid electrolyte — reducing thermal runaway risk and extending cycle life for energy storage, electric vehicles, telecom, UPS, and defence.
A solid electrolyte. A fundamentally safer cell.
Conventional lithium cells rely on flammable liquid electrolyte — the root cause of most thermal events. Cosmos Infinity replaces it with a non-flammable solid electrolyte that suppresses thermal runaway propagation and keeps the separator stable under heat.
Non-flammable solid electrolyte
Eliminates the flammable liquid electrolyte — the biggest fire-risk contributor in conventional lithium cells. Significantly mitigates thermal runaway risk.
Wider temperature range
Maintains stability across a broader operating temperature window than conventional lithium cells — suppressing the high-heat behaviour that drives thermal runaway.
Longer operational life
Delivers meaningfully longer cycle life than conventional lithium cells — lowering total cost of ownership for grid storage and fleet operators.
Performance at a glance
Measured against standard commercial lithium cells under identical test conditions. Our solid state lithium cell crosses safety thresholds that conventional lithium cells cannot — unlocking insurability, indoor siting, and OEM qualification pathways that were previously out of reach.
Built for where safety, longevity, and uptime matter most.
We're targeting B2B cell supply, formation services, and co-development partnerships across five demanding verticals.
