New long life lithium batteries being developed

A German team has developed a new long-life lithium ion battery suitable for use in electric vehicles. Criticisms of existing electric vehicles have highlighted factors such as the need to replace batteries during the life of the vehicle, at substantial cost to the owner.

A German team has developed a new long-life lithium ion battery suitable for use in electric vehicles. Criticisms of existing electric vehicles have highlighted factors such as the need to replace batteries during the life of the vehicle, at substantial cost to the owner. However this new technology is said to be able to deliver 85% of the original battery performance even after being charged 10,000 times, or around 27 years. This development suggests that the batteries could even outlast the vehicles being powered. The work has been carried out by the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg. The innovative batteries offer high storage densities of up to 1.1kW/kg, allowing for good acceleration and performance and these units well exceed the current requirements for electric vehicle batteries to be able to deliver 80% of charge after 10 years of use. The research has been funded jointly by the German Federal Ministry of Education and Research (BMBF) and the German Federal Ministry of Economics and Technology (BMWi). Further research and development work is planned, to test the technology's implementation into large cells.

    The latest technology continues to improve the quality of concrete paving while contractors are also benefiting from more adaptable equipment - Mike Woof reports For many concrete paving applications, versatility is required rather than a high production rate. Leading paver manufacturers such as GOMACO, Power Curbers, Terex and Wirtgen all offer high mobility machines that can be adjusted to cope with an array of tasks. For a contractor, the advantage of these smaller pavers is that they can be configured q

    French firm Bolloré has developed an innovative lithium metal polymer (LMP) battery. This is the result of a 15 year research and development process. Low levels of interest by OEMs in the new system encouraged Bolloré to launch its own electric vehicle featuring this battery. Called the Bluecar, the vehicle is now available in Paris through the autolib scheme. The aim of the project is to have 1,100 rental stations, 3,000 Bluecars and 6,600 charging stations in 47 areas in the great Paris area.
