Gallery: Aluminum-Celmet Could Increase Electric Vehicle Range by 300%


Much is being done to increase the range of electric vehicles, from improved lithium ion batteries to reducing the chassis weight. However, Japanese company Sumitomo Electric Industries (SEI) have developed a new material that they believe can improve the range of EVs by an impressive 300%.

The ‘super material’ is a form of porous aluminum called “Aluminum-Celmet.” It is a light-weight metal that SEI believes can be utilized in lithium ion batteries as its 3D structure can reportedly triple battery capacity. Made from nickel or nickel chrome alloy, Aluminium-Celmet is created through a combination of electro conductive coating, plastic foam, nickel plating and plastic foam. As a result, the material has a high porosity of up to 98%, which is much higher than other porous metals.  Its mesh like structure also makes it easy to cut and mould for industrial purposes – namely hybrid vehicle nickel-hydrogen batteries.

Light, conductive and providing excellent corrosive resistance, SEI believes that Aluminum-Celmet is ideal for lithium-ion and other batteries that operate at high charge/discharge voltages. More importantly, if a material can be created than improves the range of EVs, then the general public will see the advantage of owning one. This discovery has the potential to increase the production of EVs, reduce the number of gas guzzlers and reduce carbon emissions.

    Sudhanwa, the concept of the arcology has been around for a couple of decades. The concept has been revived in a few ‘megacity’. They are a fantastic way of condensing a population into a smaller area, which would preserves more green space for farms and forests. Essentially, no one would own a car anymore. All transportation would be public transport.

    All of this assumes you could get everyone to agree to live in such a dense environment.

    I think Best way to reduce traffic and gas consumption is, every company or industry should have there own residential, education etc facilities, where employees can live and go out on weekends!!i know there are limits but it can be possible!!saving of petrol is also a way to sustainability.

    I had an idea i wanted to throw outto public domain. Have electric cars for your average 100 km and under commuting trip (80-90% of trips) or shopping trip. But have a small easily detachable and attachable trailer with a generator/ conventional engine that you could own or hire from a facility that maintains them if you need to go on rarer long trips. The benefits of a hybrid vehicle but without carrying around a engine for the bulk of shorter trips where a battery unit will do the job. Ideally it will be single wheel and still allow easy reverse parking. Also battery units could be replaceable or chargeable at home like new concepts that are being trialled in Israel. 20/7/2011

    Timon : do you know which is the energy content of the glass wool? (energy used in its creation). I’m looking for that data to a work of sustainable architecture.

    When EVs can go 300 to 400 miles per charge — at highway speeds — then I believe much of all the fears associated with EVs will be relieved. EVs could really come into their own with folks that have a long commute on highways (like me). I spend far more on gas than a city dweller, putting 500 miles a work-week on my car.

    Yay. Please make this a reality. If there’s some congressman I need to petition or senator I need to call, do not hesitate to let me know. Battery research is the single most important aspect of our energy future.
