What the R&D aim of the project is
Lister recommended answerTo reduce lithium-ion battery charging time while remaining within predefined plating, temperature and degradation safeguards.
Scientific or technological uncertainty
- 01
Describe exactly which uncertainties you need to resolve
Lister recommended answerWhether the proposed adaptive charging protocol can achieve the required charge rate without unacceptable lithium plating, heat generation or long-term capacity loss.
- 02
Describe what made it a project to resolve a specified uncertainty
Lister recommended answerFast charging and lithium-plating mechanisms were known, but the combined outcome depends strongly on chemistry, cell construction, temperature and charging profile.
- 03
Describe the steps you plan to take to resolve them
Lister recommended answerTest successive charge profiles across temperature conditions, monitor thermal and plating indicators, perform repeated ageing cycles and independently repeat the chosen protocol.
- 04
What difficulties are foreseen for the project
Lister recommended answerReducing charge time can increase plating and degradation, especially at lower temperatures.
- 05
Information about any major changes to the aims, or new uncertainties that have been encountered, while running the project.
Lister recommended answerCold-condition tests may reveal that a protocol successful at moderate temperature fails plating or degradation safeguards and therefore requires preheating or derating.
- 06
How the uncertainties and other challenges were overcome (or not).
Lister recommended answerThe revised protocol would be repeated across the original cold condition and representative module variability.
An advance in science or technology
- 01
A review of the current state of knowledge
Lister recommended answerNorth American research had already established transport, plating and degradation constraints affecting extreme fast charging.
- 02
How the project sought an advance in a qualifying area of science or technology
Lister recommended answerThe project sought a new simultaneous performance envelope rather than simply increasing charging current.
Result, conclusion and evidence
Result
The protocol met the combined criteria at moderate conditions but retained a technical boundary under more severe cold conditions.
Conclusion
The uncertainty may be partly resolved rather than fully resolved if the intended cold-operating range remains unmet.
Evidence still needed
Chemistry, cell/module construction, temperature traces, plating methodology, cycle data, subgroup results and independent repeats.
