A NEW CLASS OF POWER CELL
High rate. Low cost. Zero fire risk. The first cathode that delivers all three.
LiNova's new power cells are built on a proprietary, polymer cathode made from mass-produced chemical precursors instead of mined and refined metals. Domestically sourced and manufactured, zero thermal runaway at the cell level, and up to 90% lower cost versus traditional cathodes – all while remaining manufacturable on existing lithium-ion production lines.

AN INDUSTRY-WIDE CONSTRAINT
The battery cathode is the most expensive and dangerous component in the stack — and the least reinvented.
While anodes, electrolytes, and cell architectures have seen a decade of genuine innovation, cathode innovation has primarily involved variations on existing metals and the same sourcing, cost, and thermal runaway challenges.
Supply chain
China controls the vast majority of global cathode supply — and is actively restricting technology exports. Non-Chinese manufacturers are paying a growing premium for access, or going without.
Tariff exposure
For players across the value chain, the volatile tariff landscape on the most expensive component of the battery, the cathode, is a massive business case risk.
Thermal runaway risk
Metal cathodes drive thermal runaway by releasing oxygen when they degrade under heat. This risk drives up insurance costs, adds system complexity, and limits deployment environments.
The domestic gap
The US currently meets only around 5% of its cathode demand domestically, at a 40% cost premium, and Europe has minimal commercial cathode manufacturing.
THE POLYMER ADVANTAGE
The first genuinely new cathode platform in a decade.
LiNova's polymer cathode is a proprietary, metal-free active material synthesized from mass-produced precursors which can be sourced domestically nearly anywhere. It is coated using existing facilities and processes and the resulting cells can be manufactured on existing lithium-ion lines without the need for specialized manufacturing equipment. It does not evolve oxygen, so there is zero risk of thermal runaway at the cell level.
Low-Cost Inputs
Up to 90% lower cathode cost using mass-produced chemical precursors, not mined and refined metals.
High-Rate Capability
Very high discharge rate capability, enabling smaller, lighter systems with lower nameplate capacity requirements.
Stable Cycling
Competitive cycle and calendar life due to high stability of the polymer.
Zero Fire Risk
No thermal runaway risk at the cell level due to no oxygen evolution — verified by UL9540A simulation.
Domestic Anywhere
Fully domestic sourcing nearly anywhere, from the US, to EU, UK, Canada, Japan, South Korea, and Australia.
Cleaner Manufacturing
Up to 90% less CO₂ required to produce versus conventional metal cathode processes.
Anode-agnostic Platform
LiNova's polymer cathode is a platform technology which is anode-agnostic and not limited to just lithium-ion. Our cathode material can pair with a variety of commercially available anodes, including graphite, silicon, or lithium — and has potential with sodium ions.
From platform to product
LiNova's PolyPower cell — a rate-optimized power cell engineered for high-demand, critical environments.
The LiNova PolyPower cell is the first commercial cell built on the polymer cathode platform — rate-optimized, manufacturable today, and designed for high-demand environments to eliminate tradeoffs inherent with incumbent chemistries.
Most cells are forced to optimize for one or two qualities and mitigate the resulting downsides. LiNova's polymer cathode eliminates accepted tradeoffs by offering extremely high inherent safety, high rate, high volumetric density, stable cycling, and domestic sourcing. PolyPower redefines possibilities in use cases from data centers to aerospace, defence, and more — where there is no compromise between safety and performance and every cubic centimeter counts.

A market under pressure
The data center boom has a battery problem.
Data center capacity across North America and Europe is growing 87% between 2025 and 2030. Rack power density is climbing toward 1 MW. The battery backup units keeping this infrastructure online are being asked to handle more power, in less space, at lower cost — and with less tolerance for fire risk than ever before.
For operators building and running this infrastructure, the constraints are compounding. Space is at a premium, cost pressure intensifies at scale, and safety requirements around thermal events are tightening. The available chemistries are able to address some, but not all, of these pressures simultaneously.
High Rate. Cheap. Safe. Compact. Local. Pick three.
Existing chemistries require tradeoffs that limit scaling speed – new materials are required to avoid traditional tradeoffs.

Rate
Low discharge rate means more nameplate capacity required for the same job. To back up 500 kW for 2 minutes, a 1C cell needs 500 kWh. A 20C cell needs 25 kWh — 20 times less.

Performance in numbers
New cathode. New equation.
LiNova's PolyPower takes the cost, safety, and supply chain advantages of the polymer cathode and translates them into results that no existing cell chemistry has delivered simultaneously.
-89%
All-in system cost vs. safe domestic alternative
LiNova's PolyPower costs far less than the nearest safe domestic alternative. Two compounding advantages drive it: low cell cost and a 20C discharge rate that reduces the nameplate capacity required to deliver the same backup. Less capacity needed means lower cost and less space.
-68%
System volume vs. LTO
LiNova's PolyPower requires less volume to back up 500 kW for 2 minutes. Every liter recovered is space available for compute — the hardware that actually generates revenue.

Thermal runaway risk at cell level
Remarkable safety results at the cell level. Nail penetration testing by an independent lab returned a EUCAR Level 2 — no hazard, no venting, no fire. LiNova's, and our partner's, UL9540A simulation produced no thermal runaway. These results derive from the properties of the cathode itself, not system-level mitigations.
>20C
Max pulse discharge rate
Modern hyperscaler battery backup specifications require a combination of energy density and power density that no conventional cell chemistry can simultaneously achieve. LiNova's PolyPower is the only known chemistry whose performance range reaches this target.
