Future battery technologies on charge

There have been many predictions of the future and the part to be played by grid battery storage for the renewable energy sector; however, Altech Batteries Ltd (ASX: ATC) is already there, just waiting for the rest of the world to catch up.

The grid energy storage market is expected to grow by a 28 per cent compound annual growth rate by the early 2030s. Others predict that the global grid energy storage market to grow from US$4.4 billion in 2022, to US$15.1 billion by 2027. A deeper peek into the crystal ball suggests growth from 20 gigawatts in 2020 to more than 3000 gigawatts by 2050.

Altech Batteries was early to recognise the potential of the grid storage battery market, and aspires to be a main contributor to this growth and development through the introduction of its sodium-chloride solid state CERENERGY® battery products.

The CERENERGY technology has been developed by Altech’s joint venture partner – world-leading German Government research and development institute Fraunhofer – over the past eight years, during which time it has revolutionised previous technology, achieving higher-energy capacity and lower production costs.

Together with Fraunhofer, Altech has developed cutting-edge battery specifications that meet the specific requirements of the grid storage battery sector, namely the CERENERGY 60-kilowatts-per-hour (ABS60) battery pack, as well as the CERENERGY one-megawatt-per-hour (ABS1000) GridPack battery.

The ABS60 battery pack is rated at an operating voltage of 600 volts and 100 amperes, and has been designed to provide battery backup and high performance in grid-tied commercial applications for an uninterrupted power supply.

The ABS1000 GridPack battery targets larger-scale applications, such as grid-level storage and industrial power backup.

With a capacity of one megawatt per hour, this high-performance battery system ensures a stable and uninterrupted power supply, contributing to grid stability and reducing reliance on fossil fuels. Unlike lithium-ion batteries, CERENERGY does not use lithium, copper, cobalt, graphite or manganese in its chemistry. The CERENERGY battery uses sodium-chloride (common table salt) technology, is fire and explosion proof, can operate in a wide temperature range of minus 40 degrees to 60 degrees, and has a life cycle of over 15 years.

Another string to Altech’s futuristic battery bow is the development of the company’s patented Silumina Anodes™ technology, incorporating high-capacity silicon into lithium-ion batteries for electric vehicles.

Altech declared it had cracked the ‘silicon code’ by achieving a 30 per cent higher energy battery than conventional graphite-only batteries, with improved cyclability and battery life – resulting in smaller, lighter batteries. Since then, Altech has constructed a Silumina Anodes pilot plant, scheduled to be commissioning by the end of 2023, which will provide the Silumina Anodes product for customer testing.

Altech has licensed the technology to its 75 per cent owned subsidiary, Altech Industries Germany GmbH, which has commenced a definitive feasibility study for a 10,000-tonnes-per-annum silicon and graphite alumina-coating plant in the German state of Saxony. The plant will be focused on supplying the Silumina Anodes product to the burgeoning European electric vehicle market.

‘The advancements we have made on the Silumina Anodes pilot plant are highly promising, generating significant interest in the target market,’ Altech Batteries Managing Director Iggy Tan told Future Mining.

‘Our German team are working tirelessly to commission the pilot plant and commence production of commercial samples.’
