a b s t r a c t Homogeneous Li4Ti5O12/graphene composite is prepared via an in-situ solid state reaction, after carbon pre-coating has been carried out. Its microstructure is compared with the materials prepared by a similar way, but without carbon coating. The results reveal that the carbon coating not only effectively confines aggregation and […]
Abstract It is a challenge to prepare organic electrodes for sodium-ion batteries with long cycle life and high capacity. The highly reactive radical intermediates generated during the sodiation/desodiation process could be a critical issue because of undesired side reactions. Here we present durable electrodes with a stabilized α-C radical intermediate. Through the resonance effect as […]
Established in January 2014, the ViPER laboratory serves as Purdue University’s premier, self-contained center for battery fabrication and testing. Our next-generation materials are developed using the most cutting-edge synthesis techniques, such as ultrasonic, hydrothermal, and solid-state synthesis. Our battery laminates are produced using the most accurate and precise equipment in a carefully-designed fabrication process drawing […]

Department of Mechanical and Aerospace Engineering, The Hong Kong University of Science and Technology, Clear Water Bay, Kowloon, Hong Kong, China The discharge performance of the cathodes was tested in a nonaqueous lithium-air battery that consisted of a lithium foil anode, a glass-fiber separator (Whatman GF/C), and 250 μL 1 M LiTFSI (Sigma-Aldrich, 99.95%) in […]
Scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology could replace many lithium-ion and alkaline batteries in wide use today. Stanford University scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many […]
Scientists have developed a new battery that can be recharged up to 70 per cent in only 2 minutes. The battery will also have a longer lifespan of over 20 years. Expected to be the next big thing in battery technology, this breakthrough has a wide-ranging impact on many industries, especially for electric vehicles which […]
