Big doubt about graphene in batteries

Click For Summary

Discussion Overview

The discussion revolves around the potential use of graphene in lithium-ion batteries, particularly in the context of electric motorcycles. Participants explore the implications of graphene-enhanced batteries, the identification of battery specifications, and the marketing practices surrounding battery components.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether the presence of graphene in batteries could explain the same weight for different capacity batteries, suggesting a possible factory mistake or marketing gimmick.
  • Another participant explains that lithium-ion batteries already use graphite as an anode material and that graphene is often a marketing term for modified graphite rather than pure graphene.
  • Some participants note that while graphene can enhance energy storage capacity and potentially improve charging speed, its effectiveness as a corrosion barrier is mixed and not widely commercialized.
  • Concerns are raised about the ability to identify the battery and its manufacturer based on the part number, with some expressing uncertainty about this aspect.
  • A participant mentions that battery part numbers may indicate custom packaging of standard cells, which could complicate identification and sourcing of replacements.
  • Another participant provides a link to search results related to the battery part number, suggesting further investigation is possible.
  • A later reply clarifies that certain Chinese terms related to the battery may simply indicate serial or product numbers, possibly hinting at a misprint.

Areas of Agreement / Disagreement

Participants express varying levels of skepticism regarding the claims about graphene in batteries, with some agreeing on the marketing aspects while others remain uncertain about the identification of the batteries. The discussion does not reach a consensus on the implications of graphene use.

Contextual Notes

Participants highlight limitations in identifying battery specifications and the potential for marketing terms to obscure the true nature of the materials used. There is also uncertainty regarding the effectiveness of graphene in practical applications.

TL;DR
if i put graphene into a lithium battery improves the battery in anyway?
Well people i'm looking electric Motorcycles. And the same seller it's selling a 72V50Ah battery and a 72V60Ah battery, both IN THE SAME WEIGHT, every battery in the shop occurs the same. So or we have a factory mistake, scam, witchery .....or...graphene in the lithium. I have been reading that you can use graphene to improve batteries, hence, you can raise the power practically without extra weight using this extraterrestrial material.

¿True of Fake? or ¿Graphene witchery?

Lithium ion batteries already incorporate graphite as a standard anode material. Most proposals for graphene enhanced lithium ion batteries start with this in mind. In the commercial sector, graphene is almost always simply a marketing term used to refer to highly exfoliated and restacked graphite, rather than a single 2D layer of carbon. There are a few benefits from this: first, the exfoliation and restacking breaks up the crystallinity of graphite, which allows the anode to incorporate a higher density of metal ions, leading to a somewhat higher energy storage capacity. Another benefit is the amorphous nature of the graphitic matrix can sometimes facilitate faster charging.

Additionally, graphene has shown mixed results as a physical barrier for corrosion protection, which is of perennial concern in battery fabrication. I don’t know of any commercialization of this effect, though (mainly because it doesn’t work so well).

Regarding doubts, what I would worry about is not the graphene but whether I could identify the battery (and the manufacturer) based on that type number.

I couldn't.

Very useful information, thank you very much

Me too
 
The battery part number may be a custom packaging of standard cells. Device manufacturers often request a minor modification or slightly different packaging if ordering a large quantity of component parts. The component supplier then assigns a unique Part No.

This not only makes it easier for the end-product manufacturer, but also makes them the only source for a replacement part; much additional profit gained that way.

Anyhow, in a Google search, the first four hits show Li-Ion Protection Boards with part numbers that correlate with some data in the photos.

Now, if someone that can read Chinese can be found...

Happy Hunting,
Tom

编号 just means serial number, and 产品型号 just means product number. I imagine it’s just a misprint.
