Discussion Overview

The discussion centers around the synthesis of lithium borohydride, specifically the general process of its production and the energy input required for its synthesis. Participants also explore the potential energy output from using lithium borohydride as a fuel source, particularly in the context of combustion.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about the general process of making lithium borohydride and the energy input required, expressing curiosity rather than intent to synthesize it.
  • Another participant notes that their interest was piqued by the high energy density of lithium borohydride and questions whether the energy output from combustion exceeds the energy input for its synthesis.
  • A suggestion is made to research lithium borohydride synthesis and related compounds like diborane, which has been considered as a rocket fuel.
  • One participant asserts that thermodynamic principles dictate that no process can yield more energy than is input, reiterating this point in response to the initial inquiry.
  • A follow-up question is posed regarding the specific energy requirements for the synthesis process, acknowledging a lack of knowledge on the topic.

Areas of Agreement / Disagreement

Participants express curiosity about the energy dynamics of lithium borohydride synthesis and its potential as a fuel source, but there is no consensus on the specific energy input required or the efficiency of the synthesis process.

Contextual Notes

The discussion includes assumptions about thermodynamic principles and the efficiency of chemical processes, but specific details regarding the synthesis energy requirements remain unresolved.

In general (meaning nothing specific), how is it made and how much energy (in joules) input is necessary to make it? I'm not planning on making any or anything like that, but I am curious about the general process and whether or not we can get more energy from using it than what goes into making it.Or if someone could at least answer the second part of the question that would be good enough. Thanks.

Um, this wasn't intended to be a homework question, but if you (the admins) feel it should be here then ok...I got curious about this after browsing through wikipedia, and I noticed it has a high energy density. I would just like to know if the energy that goes into making it is less than what comes out of it (via combustion).

This was part of a discussion about using it as a potential fuel source, so the questions were in that context.

Google lithium borohydride synthesis, lithium borohydride msds, lithium borohydride properties and so on.

I think diborane was considered as a rocket fuel at some point, and to some extent that's a related compound.

Your main question is easily answered by thermodynamics. There are no processes that will be able to yield more energy than you put in.

Ok, so factoring in the inefficiencies of the synthesis process, about how much energy needs to be put into the synthesis process? I have no idea how to find this out because I'm not studying this stuff, I was just asking out of curiosity.
