Proof of performance additive viability

 

Gelion (AIM: GELN), the Anglo-Australian battery storage innovator, announces
a significant milestone for its Performance Additives division's development
programme. The programme's objective is to prove up the benefits of
incorporating Gelion's performance additive particles to enable sulfur
cathodes to be paired to existing lithium-ion and lithium-ion silicon battery
anode technologies, improving overall lithium-ion battery safety, energy
density and cost.

 

The ultimate aim is to replace current lithium-ion cathode technologies in the
majority of markets globally with Gelion's sulfur cathode technology.

 

A lithium-ion silicon sulfur ('LiSiS') battery has a maximum theoretical
capacity approximately twice that of a typical lithium-ion NMC (Nickel,
Manganese, Cobalt) battery. This means that even at 50% loss of capacity a
LiSiS cell still has the same capacity as a new current lithium-ion cell.

 

When pairing Gelion's sulfur cathodes with the latest lithium silicon anodes,
the resultant LiSiS battery as compared to current lithion-ion batteries can
be expected to be a much safer (reduced flammability), much lower cost battery
(NMC is the main cost component in current li-ion batteries) and would double
the range of an EV due to its higher energy density.

 

Gelion's half-cell sulfur cathode technology has now reached 300 usage cycles
at less than 20% capacity degradation. This result proves the viability of
Gelion's additives. Furthermore, Gelion has developed ahead of schedule
electrolyte formulations that enable successful pairing of lithium silicon
anodes with its sulfur cathodes, overcoming the problem of common
sulfur-compatible electrolytes decomposing the lithium anode's graphite.

 

Together, these achievements accelerate the development of Gelion's full LiSiS
cells in a substantive manner, such that work towards a commercially viable
full cell solution can begin two years ahead of plan.

 

John Wood, Chief Executive of Gelion commented: "We are delighted to have
achieved this outcome two years ahead of our original timeline. The
lithium-ion silicon sulfur battery programme provides the path to enabling a
safe, high-energy density and lower cost battery, which is more effective than
the best lithium-ion batteries currently available and a very exciting
opportunity for Gelion."
