A technical architecture is not yet a product.

Kayphas separates third-party published capabilities, its own design hypotheses and results that must be produced through independent testing.

Priority programme

Solid-state battery: first integration proof.

Kayphas’ proof begins with qualified materials and a laboratory cell. It does not require building a CSPG plant first.

Experimental question

Can we obtain a reproducible solid-state cell whose qualified-material interfaces deliver measurable performance and safety for an initial application?

Element	Reference	Status / next proof
Cathode	Qualified cathode family	Exact selection, formulation and coating to be confirmed with technical leadership and the laboratory partner
Electrolyte	Garnet-type solid ceramic	Composition, microstructure, thickness and interfaces to be defined within the confidential experimental programme
Anode	Qualified CSPG graphite	Start with qualified CSPG; evaluate formulation variants internally and qualify Malagasy sources later
Cell	Laboratory format to be defined	No commercial format or final protocol has been selected
Performance	To be measured	No energy-density, cycle-life, fast-charge or temperature-range claim before testing

De-risking protocol

Four work packages before any product promise.

WP1

Materials

Specifications, COA, morphology, purity, moisture and traceability.

WP2

Interfaces

Electrochemical compatibility, cathode coating and electrolyte–electrode contact.

WP3

Cells

Assembly, repeatability, impedance, cycling, efficiency and failure modes.

WP4

Application

Duty cycle, temperature, safety, format and customer decision criteria.

Conditional exploratory track

Advanced photovoltaics: a direction to be confirmed through evidence.

Kayphas considers perovskite–silicon tandems a research direction to be evaluated with technical leadership, laboratories and specialized partners. Architecture, materials, processes and performance targets will be selected only after experimental comparison and intellectual-property review.

Scoping

Hypotheses and partners

Define the need, candidate architectures, partners, intellectual property and decision criteria.

Laboratory

Comparative coupons

Measure subcells, interfaces, stability and failure modes without presenting them as a product result.

Terrestrial

Progressive qualification

Evaluate stabilized efficiency, humidity, temperature, UV, reproducibility, manufacturability and cost for the target market.

Later

Space exploration

Proceed only after terrestrial proof and mission-specific qualification, retaining a qualified technology as the reference for any critical application.

Claims governance

What Kayphas has deliberately removed from its narrative.

These corrections protect the venture’s scientific credibility and give future partners a clear basis for collaboration.

520 Wh/kgNot retained for the graphite–ceramic-electrolyte platform

A target at this level would require another risk branch, such as lithium metal or anode-free.

Universal platformReplaced by a technology family

A shared chemistry can serve several segments, but electrodes, format, pressure and BMS must be tailored.

Zero thermal runawaySafety hypothesis to test

A ceramic electrolyte alone does not guarantee the absence of system failure.

Scientific context: a published analysis estimates about 418 Wh/kg for a theoretical Li | 15 µm LLZO | NMC811 design under its mass-balance assumptions; this is not demonstrated product performance. Chemical Society Reviews, 2025 ↗

Help us turn this architecture into an experimental protocol.

Kayphas is looking for a technical co-founder, a laboratory and suppliers able to document the materials.
