Researcher of new battery accepted my invitation for interview in this website.

[All Darc]

I get response from Maria Helena Braga, researcher who developed the glass electrolyte used in the new battery she and John B. Goodenough created.

I would like t ask the attention, if you allow me, of the Ecomodder moderator and adminstrator, for some questions :

Would you allow me, help me, to post the interview and following debate with forum member, in a place of spotlight/distintion of Ecomodder website ?

May I ask for some speciall supervision of moderators, just to ensure a welcome not confrontative atmosphere during the debate with the researcher ?
I'm sure almost everyone in Ecomodder are nice, but just in case someone get a bit out of line.

My idea it's to make a detailed interview with my questions, and post it in the Forum, to be followed with other questions from Ecomodder forum members.

Let's do it.
I would really like to see this glass battery thing pan out even if they are just cheaper.

[All Darc]

Yeah, let's get a nice interview.

But I need some response from adminstrator of Ecomodder, cause if she was nice to accept, we need to put the final interview in someplace of spotlight in the Ecomodder website.

[Daox]

Yeah, we can certainly do that. Way to take some initiative All Darc.

[All Darc]

Thank you.

Ecomodder exclusive interview?

[All Darc]

Well, I think it is.

I plan to try questions not found in the dozen web reports about the discovery, followed by questions of ecomodder forum members. It could be the most complete insight about these new promissing bateries posted on web.

• Doesn't solid state imply a non-chemical store of energy?
• What voltage does the cell produce?
• What method is used to charge the cell and is it tolerant of over-charging?
• Does it require a BMS?
• How flat is the discharge curve?
• If dendrites do not form, then can the cell be discharged completely without causing undo damage?
• What are the current development challenges?
• How difficult/expensive is creating a sub-micron layer of lithium?
• If sodium is used, is there risk of fire if a damaged cell is exposed to water?

-I will try answer from the articles I saw and interviews. But I will also send her the relevant questions of these anyway.

- It's indeed "glass" and not glass, and not. It's "glass" particles and not a single piece. She did a jelly roll version. It uses a liquid between the crystal pieces, If I remamber well.
Don't know about optical properties, but electrolyte properties of transmission it's almost the same as liquid Li-Ion.

-Produces 3V, or 6V when the capacity increases over cycles.

-Challenges (suposed) it's scaling-up. Need to try larger version to see if works as good.

-It can use sodium or lithium.

-Charge discharge curves :







-Oceans do not got fire. oK,
I'M JUST KIDING IN THIS SPECIFIC QUESTION

1) The word GLASS connotates brittleness and fragility, so what KIND of glass is used?
2) Could TEMPERING help?
3) What glass purity (optical transmissibility) is required?
