Re: Electrolysis of Ionic Hydrides-Deuterides?

[Frederick Sparber]

A private message I received yesterday.

 

"You may want to check out the work of Liaw:

for example:

Liaw BY, Ding Y; Fusion Technol. 26T (1994) 63.

"Charging hydrogen into hydride-containing molten salts".

** Molten salt, Ni, hydrogen, excess heat, res+

Liaw et al have previously used a molten salt system to produce excess heat

(and even He) at Pd anodes in a LiCl-KCl salt melt (400 C) containing LiD;

now

they try a Ni anode and LiH. Several things go wrong, stainless steel

holders

corrode, the LiH gets used up so that the electrochemistry changes to that

for

the melt itself. The input power just to keep the melt molten is 26 W; they

detect some instances of about 0.5 W excess heat and regard this as

significant.

 

Clear observation by Liaw et al. [11] for 25 W of excess heat at greater

than 460oC during anodic deposition of D- ions onto a Pd anode from a molten

salt electrolyte. Excess power exceeded electrolysis input power by factor

of 15; power density was 627 W cm-3 Pd; duration of high power was 1 day, of

elevated power was 4 days. Power controlled by current density. Single

successful anode. (1990)"

With the flurry of activity centered on Lithium Hydride and the

seven known Lithium-Tin Compounds for Lithium Ion battery technology,

one wonders if Lithium Hydride or Deuteride dissolved

in molten Tin could form a Li (x)H(y)Sn(z) phase that would

allow "plate out" of Hydrogen or Deuterium at the anode.
