Discussion Overview

The discussion centers around the degradation of rechargeable lithium batteries when left unused for extended periods compared to those that are regularly used, charged, and discharged. Participants explore the implications of battery chemistry and advancements in technology that may affect degradation rates.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether a new rechargeable lithium battery left unused for years degrades slower or as fast as one that is regularly used, and what the implications are for starting to use it after several years.
  • Another participant references an article by a PhD researcher that discusses lithium-ion battery degradation over time.
  • A different participant mentions a recent article about advancements in lithium battery chemistry that could potentially prevent degradation.
  • One participant expresses interest in the implications of new lithium-sulfur battery technology and its potential advantages, particularly regarding reduced environmental impact and its relevance to electric aircraft.
  • A repeated question about battery degradation is posed, along with a reference to Battery University for additional insights on prolonging lithium-based batteries.

Areas of Agreement / Disagreement

Participants express differing views on the degradation of lithium batteries when unused, and while some reference articles that suggest advancements in battery technology, there is no consensus on the extent of degradation or the effectiveness of new technologies.

Contextual Notes

The discussion includes references to various articles and studies, but the assumptions and specific conditions under which battery degradation occurs are not fully explored or agreed upon.

Who May Find This Useful

Readers interested in battery technology, environmental impacts of battery production, and advancements in energy storage solutions may find this discussion relevant.

If a rechargeable Lithium battery is new and not used for a few years, will it degrade much slower or as fast as the one that is regularly used, charged and discharged? What if I only start to use it after a few years for the first time, will the battery already degrade so badly

That is some interesting stuff, would be a real game changer! First thought came to my mind was https://evtol.com/news/oxis-lithium-sulfur-battery-bye-aerospace/
I hope even half of the advantages can be commercially realized,particularly the reduced mining impact.
With NASA's interest in electric aircraft I was also surprised to find no hits on the NASA or JPL technical reports servers, that will probably change soon though.
