Abundant materials
Potassium is widely available and geographically distributed, providing a fundamentally different raw-material base from lithium-dependent systems.

Why potassium-ion?
Different chemistry.
Different chemistry.
Different opportunity.
Lithium-ion is extraordinarily successful. But infrastructure storage does not always optimise for the same things as a vehicle pack. QED is investigating whether potassium's material base and transport behaviour can support a different engineering trade-off.
Interesting transport physics
Selected potassium electrolytes can show favourable solvation and desolvation behaviour. The magnitude is formulation-specific and must be measured in the chosen system.
Different design priorities
Infrastructure batteries can value power availability, service life, maintainability, delivered energy and material resilience as much as minimum gravimetric mass.
The QED question
Can architecture preserve useful performance?
The question is not whether architecture can create more thermodynamic energy. It cannot. The question is whether better transport architecture can keep more installed active material accessible at useful loading and duty.
01
Useful potassium storage
Material credibilityCan titanium-dioxide nanostructures provide reproducible potassium storage at an appropriate operating potential?
02
Architecture advantage
Matched comparisonCan controlled transport pathways reduce polarisation and preserve utilisation relative to matched conventional electrodes?
03
Practical loading
Engineering relevanceDoes any measured advantage survive when loading, density and real cell constraints increase?
Evidence boundary: any QED advantage must appear as a reproducible transport, polarisation or utilisation effect against appropriate controls. A plausible mechanism is not a result.
Where it matters first
Infrastructure first.
QED is initially focused on duties where availability, maintainability and lifetime delivered energy can matter more than minimum battery mass. Market access still depends on measured power, degradation, safety, temperature behaviour, cost and qualification.
Primary beachhead hypothesis
Industrial UPS, telecom & remote infrastructure
Repeated duty, mission-critical availability and meaningful service costs make these attractive environments in which to test the value of a system designed for durable service.
UPSTelecomRemote sitesDistributed energy
Stationary-storage demonstrator
A system-level route for measuring round-trip efficiency, thermal behaviour, controls and representative service duty.
Materials handling & selected lead-acid replacement
Potential applications include industrial vehicles and low-voltage auxiliary duties, including the auxiliary battery systems still required inside electric vehicles.
Domestic storage & mobility
Later directions only after the platform clears full-cell energy, safety, life, manufacturing and certification gates.
Validation-led development
Evidence before claims.
Measured results replace assumptions. Negative results are design inputs. Complexity is added only when a simpler experiment shows that the next layer is justified.
