What does TRL 5 mean in battery research?

Technology Readiness Levels provide a common language for describing development maturity. TRL 5 sits between laboratory validation and a full system demonstration.

What TRL 5 supports

It indicates that important elements have been integrated and tested under conditions that represent the intended use more closely than a basic laboratory experiment.

What it does not mean

TRL 5 does not mean a product is certified, manufacturing-ready or proven in every application. Readiness is specific to the architecture, test environment and evidence available.

The next step

Development normally moves toward an application-specific demonstrator, measurable performance requirements and a wider validation programme.
