Batteries and Fuel Cells
Cobalt-oxide mesoporous nanospheres key to longer life auto batteries
Batteries and Fuel Cells : 11 March, 2015
Lithium-ion batteries power our phones, laptops, and many other portable electronic devices. But there are limitations inherent in current lithium-ion technology that prevent them from being used more widely in electric vehicles and other high-power applications.
Parasitic conduction heralds advance in solid-state lithium batteries
Batteries and Fuel Cells : 29 May, 2014
A team of researchers at Tohoku University in Japan has created a new type of lithium ion conductor for future batteries that could be the basis for a whole new generation of solid-state batteries. It uses rock salt Lithium Borohydride (LiBH4), a well-known agent in organic chemistry laboratories that has been considered for batteries before, but up to now has only worked at high temperatures or pressures.
Supercapacitors - graphene active electrodes well ahead of today’s lithium-ion batteries
Batteries and Fuel Cells : 17 January, 2014
An IDTechEx report gives a general overview on supercapacitors and tabulates chemistries and activities by company, with pie charts of technology adoption by number of manufacturers and forecasts. It explains where supercapacitors are already replacing lithium-ion batteries and why.
Bendable thin-film lithium ion battery (LIB) for wearable electronics
Batteries and Fuel Cells : 20 August, 2012
High-performance flexible power sources have gained attention, especially for bendable, implantable, and wearable electronic systems. Although the rechargeable lithium-ion battery (LIB) has been regarded as a strong candidate for a high-performance flexible energy source, compliant electrodes for bendable LIBs are restricted to only a few materials, and their performance has not been sufficient for them to be applied to flexible consumer electronics including rollable displays.
Electrolyte containing nanocrystals raises fuel cell efficiency
Batteries and Fuel Cells : 04 April, 2011
The addition of extremely small crystals to solid electrolyte material has the potential to considerably raise the efficiency of fuel cells. Researchers at TU Delft were the first to document this accurately, and their second article on the subject in a very short time has now been published in the scientific journal, Advanced Functional Materials.
Electrolyte suitable for thin-film printing set to revolutionise battery construction
Batteries and Fuel Cells : 19 March, 2011
A company in Orlando, Florida, USA, called Planar Energy, is about to complete a pilot production line that could eventually lead to smaller, cheaper, more powerful batteries for consumer electronics. Planar has discovered a solid electrolyte it believes is suitable for thin-film printing.
Developments in polymer-based materials for energy storage
Batteries and Fuel Cells : 23 October, 2008
Developments at Penn State, MIT and Delft are leading the way in fundamental research into new ways of managing electrical energy. Traditional ceramic materials have high weight and are very fragile, whereas mobile electronics need light weight electrical energy storage
Devices offer direct battery operation and choice of configurations
Batteries and Fuel Cells : 29 April, 2006
Vishay Intertechnology, Inc. an 80.4%-owned subsidiary of Vishay Intertechnology, Inc. today released a family of new analog switches designed for direct battery operation in portable applications. Offering low on-resistance and low-level logic control through the full voltage range of 1.6 V to 4.3 V, the new switches are aimed at end products including cell phones, set-top boxes, PDAs, and media players.
