A decade ago, a young man Naval engineer at the British nuclear submarine started helping to drive his own electric battery. Under the frozen polar ice-cap during the Cold War, the sub-mariner did not know that, in the 21st century, battery technology will become one of the largest single sector in the world. Even the planet But their curiosity stayed with them, and about 20 years ago, they decided to follow that dream, which took many years under the waves.
Trevor Jackson's journey began, many research was done in research. It was not affected by lithium batteries, experiments that came to dominate the battery industry, but the so called 'aluminum-air' With Batteries
Technically it has been described on "(al) / air" batteries, this battery is almost a number of stories about the world. For starters, the aluminum-air battery system can produce enough energy and power for the dynamics like driving range and gasoline-powered cars.
Sometimes the & # 39; metal-air & # 39; Known as a battery, this has been used for many years by the & # 39; off-grid & # 39; Apps are successfully performed, as batteries empower Army Radios. The most attractive metal in this type of battery is aluminum because it is the most common metal on earth and has its highest energy density.
Think about air-breathing batteries that use aluminum & # 39; fuel & # 39; As does. This means that it can provide vehicle power with energy emerging from clean sources (hydro, geothermal, nuclear etc.). There is power source for most aluminum smelpers worldwide. The only waste product is aluminum hydroxide and can be returned as a feedstock in smelter – guess what? – Make more aluminum! This cycle is therefore very durable and different from the oil industry. You can also reuse aluminum tin can and use it to make batteries.
Imagine that – power source Extremely different from the polluted oil industry
But rarely anyone was using them in mainstream use. Why?

Aluminum-air batteries were around for a short time. But the problem with a battery that's aluminum & # 39; eating & # 39; The electricity that was produced by it was that it was not just efficient. The use of electrolyte does not just work well.
This was important. Electrolyte is a chemical in the battery that gives the flow of electrical charge between cathode and ano. When the device connects to the battery – a light bulb or electric circuit – chemical reactions occur on electrodes that make up the electrical energy flow on the device.
When the aluminum-air battery starts running, the chemical reaction is a & # 39; prison & # 39; Produces a product that can slowly block the airways in the cell. It seemed like a messy problem to deal with the researchers.
But after many experiments in 2001, Jackson developed that was believed to be a revolutionary type of electrolyte for aluminum-air batteries, which had the potential to remove barriers to commercialization. His specially developed electrolyte did not produce hate-gel that would destroy the aluminum-air battery's efficiency. It looked like a game changer.
Success – if proved – had a huge probability. The lithium-ion battery had about 8 times the energy density of its battery. She was incredibly excited. Then he tried to tell the politicians …

In 2001, Lord & # 39; Jim & # 39; Although there is a detailed demonstration of Knight's working battery, email correspondence & # 39; to pass on Tony (Blair) & # 39; There was no interest from the UK government after the promise
And Jackson faced bureaucratic hurdles. The UK Government's official innovation organization, Innovate UK, emphasizes lithium battery technology, not aluminum-air batteries.
They were struggling to confront public and private investors for their backing, as in the field there was a hold of "lithium battery lobby".
Something else on Lithium Battery means that the UK government is effectively leaving the table, which can revolutionize electrical storage and mobility, and contribute to the fight against carbon emissions and will lead the UK towards its pollution-reducing targets.
After disappointed in the UK, Jackson raised sticks and got better support in France, where he moved to R & D in 2005.
After all, in 2007, the potential for Jackson's discovery was confirmed independently at the Polytech Nantes Institute in France. Its advantages over lithium-ion batteries (and still have) increased the cell voltage. They used ordinary aluminum, they produced very little pollution and had stable, long-term power output.
As a result, in 2007 the French government formally & # 39; s strategic and national interest in France & # 39; Technology was supported.
At this time, the UK's Foreign Office suddenly woke up and took notice.
He promised Jackson that in the UK the UK & # 39; Returning & # 39; Then the UK & # 39; UKTI & # 39; 300% will try.
However, in the year 2009, the UK's Technology Strategy Board refused to return the technology, stating that the Automotive Council Technology Road Map 'excludes this kind of battery. & # 39; The carbon trust agreed that it is actually a & # 39; reliable CO2-reduction technology & # 39; Which he did not help to push Jackson forward.
Meanwhile, other governments were more enthusiastic to search for metal-air batteries.
The Israeli government, for example, directly invested in Firginge, which is working on early aluminum-air technology. Here's one, accepted corporate, video which actually shows the advantages of a metal-air battery in an electric car:
Russian aluminum company RUSAL developed a CO2-free smelting process, which, in essence, could make an aluminum-air battery with a CO2-free process.
Jackson tries to tell the UK government that they are making a mistake. Presenting to the parliamentary selection committee for business-energy and industrial strategies, he explained how the UK has created a trend towards lithium-ion technology that led to the battery-tech ecosystem, which funded millions of lithium-ion research from billions Was pound. Prime Minister Theresa May in 2017 Lithium-Ion industry was more supportive.
Jackson (below) refused to take any for the answer.

He applied to the UK's Defense Science and Technology Laboratory. But in 2017 they did not have a & # 39; non-fund & # 39; While responding to the decision, who dismissed the technology, DSTL had its own program on aluminum-air technology, which was devoted to finding better circulation at Southampton University.
Jackson instead turned to the auto industry. In 2013, he formed his company MAL (branded as "Metallic") and used seed funding to successfully test a long-range design of power pack in its laboratory facilities in the UK's Tavistock.
Here it is on the regional BBC channel explaining the battery:
Nissan Leaf and Mahindra Reva & # 39; G-Vis & # 39; He worked closely with at least engineering to design and develop long-term replacement power packs for electric cars. At that time, Nissan was & # 39; Beyond Lithium Beyond & # 39; (His words) expressed strong interest but he did not take Leone batteries to the & # 39; Leaf & # 39; Were already committed to fit on. Uncredited, Jackson focused on G-Vis and began to build full-size battery cells for testing and showed that aluminum-air technology was better than any other existing technology.
And now this burden on Lithium-Ion is pulling the industry back.
The fact is that lithium batteries now face significant challenges. Technology has developed; Unlike aluminum, lithium is not recyclable and lithium battery supplies are not guaranteed.
The advantages of aluminum-air technology are numerous. Without a battery charge, a car simply swaps the battery in seconds, completely & # 39; charging time & # 39; Can be removed Most current charging points are rated at 50 kW, which is about one hundred times in the 5th minute to charge lithium batteries. Meanwhile, hydrogen fuel cells will require large and expensive hydrogen distribution infrastructure and a new hydrogen generation system.
But Jackson has continued to push, make sure his technique can address both the future power requirements and the atmospheric crisis.
Last May, he started getting much needed recognition
As part of its UK Startups Technology Developer Accelerator Program (TDAP) in the UK's Advanced Propulsion Center, Metalactic Batteries, as a part of Grant Investments, take their technology to the next level. UK TDAP is part of the 10-year program to make world leader in low carbon propulsion technology.
Catch? This will pay £ 1.1 million to fund these 15 companies.
And for Jackson? It still raises money for Metallectric and spreads the word about the potential of aluminum-air batteries to protect the planet.
Heaven knows, at this time, he can use it.
