1.2V Ni-MH battery

British scientists make revolutionary breakthrough in 1.2V Ni-MH batterymaterial technology

Scientists have discovered a new material that holds the key to unlocking the potential of hydrogen-powered cars.

With the rise of the new energy industry in recent years, the world has gradually moved away from fossil fuel-powered cars and trucks, and more and more green alternative technologies are being explored, such as electric battery-powered cars.

British 1.2V Ni-MH batterymaterial technology has achieved a revolutionary breakthrough? Hydrogen power applications hope to double

One of the "green" technologies with great potential is hydrogen power. However, a major obstacle that the application of this hydrogen power must overcome is the size, complexity and cost of the fuel system - until now.

An international research team led by Professor David Antonelli of Lancaster University in the UK has discovered a new material made of manganese hydride that provides a unique solution. This new material will be used to make molecular sieves in fuel tanks - storing hydrogen and working with fuel cells in hydrogen-powered systems.

This material, called KMH-1 (Kubas manganese hydride-1), will enable the design of fuel stacks to become smaller, cheaper, more convenient and more energy-dense than existing hydrogen fuel technology, and greatly exceed the performance of battery-powered vehicles.

Antonelli, Professor of Physical Chemistry at Lancaster University, said: "Our material is cheap to make and it can store energy at a much higher density than lithium-ion batteries, so we could see hydrogen 1.2V Ni-MH batterysystems costing five times less than lithium-ion batteries." This battery technology will give lithium-ion batteries a greater range, potentially extending the journey between charges by four to five times. "

The material exploits a chemical process called kubas binding. This process stores hydrogen by keeping hydrogen atoms away from hydrogen molecules and works at room temperature. This eliminates the need to split and combine bonds between atoms, high energy and extreme temperature processes, and complex equipment to deliver it.

The KMH-1 material also absorbs and stores excess energy, so no external heating and cooling is required. This is crucial because it means cooling and heating equipment does not need to be used in the vehicle, resulting in a more efficient system than existing designs.

The sieve works by absorbing hydrogen at about 120 atmospheres of pressure, which is less than a typical scuba tank. When the pressure is released, it releases the hydrogen from the tank into the fuel cell.

The researchers' experiments showed that this material can store four times more hydrogen in the same volume as existing hydrogen fuel technology. This is great for vehicle manufacturers because it gives them more flexibility, allowing them to design 1.2V Ni-MH batteryelectric vehicles with four times the mileage, or enabling them to reduce the size of the tank by four times.

While vehicles, including cars and heavy trucks, are the most obvious applications, the researchers believe that KMH-1 has many other applications.

"This material can also be used in portable devices such as drones or mobile chargers so that people can go on a week-long camping trip without charging," said Professor Antonelli. "The real benefit this brings is in situations where you expect to be off the grid for a long time, such as long-distance truck trips, drones and robots. It can also be used to manage houses or remote areas with fuel cells. "

The technology has been licensed by the University of South Wales to a spin-off company, partly owned by Professor Antonelli, called Kubagen.

The research, detailed on the cover of the paper "Manganese hydride molecular sieves for practical hydrogen" and in the print edition of the academic journal Energy & Environmental Science, was funded by FCA, Hydro-Quebec, the University of South Wales, the Institute for Engineering and Environmental Physical Sciences Research Council (EPSRC), the Welsh Government and the University of Manchester.

Tarek AbelBaset, senior technical engineer, Advanced Development Engineering, 1.2V Ni-MH batteryAmerica, said: "Storing hydrogen is a huge challenge. We have worked with Professor Antonelli and numerous academic and government funding agencies for nearly 15 years, and we are proud of this result. The development of the KMH-1 material shows real promise. "
