Altech is progressing its sodium alumina solid state battery technology with the launch of a 1 megawatt hour GridPack design for the renewable energy and grid storage market.

This design, which is rated at 600 volts DC and 100Ah and can be arranged in series to achieve the required rating, was developed following preliminary discussions with potential off-takers and to minimise on-site installation of the company’s individual ABS60 60KWh battery packs.

Each GridPack will have up to 20 60KWh battery packs installed and connected to a pack power management system in a sea container, making it easy to transport by sea or road while adhering to Ingress Protection (IP) 65 standard that ensures complete protection from both dust and inclement weather.

Altech Batteries (ASX:ATC) adds that the GridPacks are modular and stackable, which reduces their footprint, and have a “plug and play” feature that makes them easy to install in remote locations.

They also operate noiselessly, have no need for moving parts such as cooling fans, feature low maintenance costs and are capable of operating in any climate without need for thermal management – a key advantage of sodium-alumina solid state batteries over more traditional lithium-ion batteries.

Ground-breaking technology

Altech’s CERENERGY® sodium-alumina solid state battery uses table salt and is lithium-free, cobalt-free, graphite-free, and copper-free, eliminating exposure to critical metal price rises and supply chain concerns.

They are capable of operating at a very wide temperature range of -40C to plus 60C, have a life span of more than 15 years, and are proof against fire and explosions.

Additionally, German government owned Fraunhofer, Europe’s largest application-oriented research organisation, have estimated that the cost of producing CERENERGY® batteries should be in the region of 40% cheaper than lithium-ion batteries.

Sodium-alumina solid state batteries have energy capacities comparable to lithium iron phosphate batteries though they have longer charge and discharge times. This is perfectly acceptable for grid storage uses though, as it does not require the delivery of very high power in a short period.
