A greener future in store?<\/figcaption><\/figure>\n <\/p>\n
<\/p>\n
But combining improved performance with safe, eco-efficient, operation is a tall order. <\/span>Michel Armand and his team from\u00a0 the Universite de Picardie Jules Verne in France showed that a sustainably sourced organic version of the ubiquitous lithium-ion battery could provide the answer (Nature Materials, DOI:10.1038\/NMAT2372).<\/p>\n <\/p>\n
Armand\u2019s battery, built around a novel lithium-hydrocarbon anode, delivers up to three times the typical minimum energy capacity needed for practical applications but is environmentally friendly too.<\/p>\n
<\/p>\n
The organic acids used to make the electrode are readily synthesised on a sustainable basis from abundant recycled plastics. <\/span>They also appear as a metabolic by-product when bio-organisms act on common hydrocarbons like benzene.<\/p>\n <\/p>\n
The team say their device generates less heat and is more thermally stable compared with conventional Li-ion batteries with titanium or pure carbon electrodes. <\/span>That makes it an attractive option for hybrid vehicles, where the presence of petroleum fuels alongside electricity makes battery meltdown unthinkable; w <\/span>e glimpsed the consequences of thermal instability in 2006, when a manufacturing defect in Sony laptop batteries caused some devices to burst into flame.<\/p>\n <\/p>\n
Lithium-ion batteries must not show memory effect, so they retain their capacity when recharged from a partly charged condition. <\/span>In the tests, performance of the organic battery dropped off only slowly during repeated recharge cycles, indicating a desirable reversibility of the chemistry. Before-and-after-charge x-ray diffraction measurements confirmed the structural stability of the electrode. <\/span><\/p>\n <\/p>\n
The team also say their device is lighter, the novel chemistry allowing replacement of heavier copper components with aluminium ones elsewhere in the battery. <\/span>That makes all the difference in an electric vehicle where every gram counts.<\/p>\n","protected":false},"excerpt":{"rendered":"Increasing demand for electric vehicles and portable electronic devices is driving a parallel need for environmentally friendly batteries.
