AMTE Power announces significant progress on battery cell development

Battery cell manufacturer AMTE Power has announced significant progress across key areas of the business – with development of its three core cell products continuing to gather pace.

The company’s Ultra High Power, Ultra Safe and Ultra Prime products are focused on the high power, specialist automotive and energy storage sectors. According to the company, AMTE Power currently has a number of key commercial opportunities for its products and a strengthening overall pipeline of opportunities being discussed with an unweighted value in excess of £240 million. 

AMTE Power published its operational and trading update to the stock market yesterday (23 August 2022). The update covers significant development of the business’ differentiated cells for the automotive and energy storage markets.

Ultra High Power

These cells are ideally suited to key automotive sectors of high-performance electric vehicles, hybrid vehicles, and fuel cell electric vehicles, with an increasing number of automotive original equipment manufacturers (OEM) committing to fuel cell electric vehicle production.

The Ultra High Power cells that are currently being produced on GigaFactory production equipment at the UK Battery Industrialisation Centre (UKBIC) are delivering well against the company’s target specification, at ever increasing volumes. Testing shows a very low internal resistance, which allows both very fast charging and exceptional power delivery.

Extensive trials have taken place and whilst tests are still ongoing, the cells have consistently achieved a full charge within six-minutes in initial testing, with further tests planned in the coming weeks. This builds upon 1,000 charging tests previously completed and supported by Imperial College.

The Company has currently signed five non-binding memoranda of understanding for the cell with key automotive partners as it moves toward supply contracts that will be supported by AMTE’s Dundee MegaFactory scale up, as announced on 28 July 2022. Combined, these steps will significantly reduce risk of delivery.

Ultra Safe

With the continued challenges on pricing of key materials for batteries, there is significant interest in AMTE Power’s sodium ion cell, Ultra Safe, for energy storage systems. This cell uses no lithium, cobalt or copper and is more cost effective, safer and sustainable than lithium cells. It is, therefore, viewed as a natural alternative for many applications to lithium-based battery products, with interest and engagements through much of the value chain from major energy generators to home energy storage producers.

Cell development is nearing completion, with the cell having reached its energy density specification of 140 Wh/kg. It has been designed for energy storage applications and is planned to commence production at Thurso later this year for delivery to customers for initial evaluation and project and supply validation. In March 2022, the company announced a contracted initial order of 1,000 cells from AceOn for its portable energy storage unit. The Board anticipates that further contracts will be entered into as AMTE prepares to invest in its Dundee MegaFactory.

Ultra Prime

Ultra Prime is a non-rechargeable cell designed for use in some of the most difficult environments on earth, with very high energy density and high-temperature performance. This cell also has a low self-discharge, making it well suited for applications where temperature, access and long duration of charge retention are key considerations.

AMTE Power’s Ultra Prime cell continues to progress to schedule and to demonstrate the performance expected. AMTE Power has a contracted supply agreement in place for this cell and is now progressing to initial supply and trials with that customer.


In order to execute on strong interest from customers of its Ultra High Power cells, the Company is seeking to utilise the UKBIC where the UK Government has invested £130m into a high-rate cell production facility. Discussions are ongoing with the UKBIC in relation to this, with the expectation of initial customer purchase orders being contracted later in the year, followed by larger volume contracts, underpinning the construction of the Dundee MegaFactory.

For its Ultra Safe cell, the company will look to utilise its Thurso site to initially supply product to customers, prior to moving to the Dundee MegaFactory.

For its Ultra Prime cell the company will look to utilise its Thurso site to supply product to customers with initial sales expected to commence in FY2024.

Focusing on the Thurso production facilities and UKBIC will enable AMTE Power to leverage its competitive advantages and development pipeline to drive the next stage of its growth towards the MegaFactory.


AMTE Power plans to have its new, state of the art 0.5GWh MegaFactory in Dundee ready within three years. The facility will be capable of producing annually more than 8 million cells with a revenue stream in excess of £200m.

Due to the high value nature of AMTE Power’s products, a factory can be profitable at a smaller scale than the size of factories at multiple GWh size, benefiting from quicker commissioning time, more flexibility in location, less investment and a faster path to profitability. AMTE Power considers this as a strong stepping- stone towards building GigaFactories in the future.

AMTE Power has received an indicative offer letter from Scottish Enterprise regarding a potential package of funding and business support and discussions continue towards a final grant.

The Company’s Australian joint venture company, Bardan Cells, continues to pursue its commercialisation strategy to manufacture, leveraging the Ultra Storage cell which is planned to be completed in the calendar year.

Commercial partners

AMTE Power is working on new commercial partnerships, as well as progressing existing commercial and development partnerships including with Cosworth, Viritec, MAHLE Powertrain, Sprint Power and BMW, towards firmer commercial agreements.

The Directors believe that installations of home energy storage batteries will rise from 6GWh in 2019 to 155GWh annually by 2030 (Source: Bloomberg). Currently only five per cent of the energy used to heat homes today comes from low-carbon sources and massive growth is expected as part of the transition to net zero in the next 15 to 20 years.

In the electric vehicle market, the UK Government has set a 2030 deadline to end the sale of petrol and diesel cars. In addition, legislation is coming into force in just two years’ time which will stipulate that batteries for electric vehicles made in the EU or UK need to be manufactured with at least 50 per cent of locally sourced materials by value in order to avoid tariffs.

Kevin Brundish, CEO, AMTE Power, said: “It is an exciting time for AMTE Power. We are on the cusp of commercial volume production for our high-value cells, and we continue to see a huge amount of customer interest in our products. Our products and expertise will play a fundamental part in the UK energy transition, and we remain passionate about reaching a net zero economy.

“We are today confirming that the business is trading in line with our expectations. Looking ahead, the AMTE Power team is working incredibly hard on all fronts to deliver on our range of products and strategic goals. We look forward to keeping all stakeholders updated on our future successes.”
