Altech Batteries: Move over lithium – these batteries are made of table salt!

Altech Batteries CFO Martin Stein on 3AW, 2GB, 4BC & 6PR Bulls N' Bears Report

Listen to ASX-listed Altech Batteries CFO Martin Stein talk to Matt Birney on the Bulls N’ Bears Report about Altech’s remarkable new sea container sized batteries that have no lithium, cobalt, manganese or graphite – and they last for years!


Altech has three battery-focused projects and products including its “Silumina” lithium-ion battery anode product, a proposed 4500t per annum high-purity alumina project and its remarkable “Cerenergy” battery technology that run almost exclusively on table-variety salt believe it or not. The company recently launched its very first design for its Sodium Alumina Solid State batteries that Altech says could revolutionise the grid storage market.


Matt Birney - Welcome to Bulls N' Bears brought to you today by battery technology developer, Altech Batteries.

Matt Birney - ASX code: ATC. I'm Matt Birney and I'm joined now by the CFO of Altech Batteries, Martin Stein. Hi Martin.

Martin Stein - Hi Matt. Thanks for having me.

Matt Birney - Okay so Altech has two key battery-focused products including its Silumina lithium-ion battery anode product and its remarkable CerEnergy battery technology that runs almost exclusively on, believe it or not, table variety salt.

Matt Birney - The company recently launched its very first design for its sodium alumina solid-state Cerenergy batteries and Altech says these batteries could revolutionise the grid storage market.

Matt Birney - Okay Martin how do you make big batteries out of salt? What else do these things contain?

Martin Stein - So the chemistry, the key materials are, sodium chloride which is common salt water as well as nickel powder. We don't use copper,  cobalt, graphite or lithium like our lithium-ion battery competitors.

Matt Birney - So how big are these things and how do you plan to move them around?

Martin Stein - Well we recently announced our one megawatt-hour GridPack design and what we'll be doing is putting up to 20 60 kilowatt-hour battery packs within a standard sea container.

Martin Stein - That sea container can then be shipped or transported to the customer's premises, dropped on the deck, it's a simple plug and play design and within a few minutes the customer will have access to one-megawatt hour of battery capacity.

Matt Birney - What does your typical customer look like? Who are you trying to sell these things to?

Martin Stein - So we're targeting grid storage application so we're talking about big energy producers and solar and wind farms and the like that have intermittent power supplies, for example, a solar pipe can produce during the daylight hours but it needs to store the excess in a battery so that it can be returned to the grid at night time and evenings when the electric vehicles are being charged and the other energy requirements are there.

Matt Birney - So how do you weigh the advantages of your Cerenergy batteries against say lithium for instance?

Martin Stein - So the Cerenergy battery is completely fire and explosion-proof. We have a very large temperature range of between -40 and 60 degrees and we have a long operating license up to 15 years.

Matt Birney - Martin Stein from Altech Batteries.

Matt Birney - Thanks for joining me on Bulls N' Bears today and remember we're only here to give you information not advice which you should of course seek independently.

Matt Birney - I'm Matt Birney and this is Bulls N' Bears.
