New battery technology developed by Chinese researchers

Chinese researchers develop new battery technology, EurekAlert, 25 Mar 16CHINESE ACADEMY OF SCIENCES HEADQUARTER A Chinese research team from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has developed a novel, environmentally friendly low-cost battery that overcomes many of the problems of lithium ion batteries (LIB). The new aluminum-graphite dual-ion battery (AGDIB) offers significantly reduced weight, volume, and fabrication cost, as well as higher energy density, in comparison with conventional LIBs. AGDIB’s electrode materials are composed of environmentally friendly low cost aluminum and graphite only, while its electrolyte is composed of conventional lithium salt and carbonate solvent.

The research, published in “A Novel Aluminum-Graphite Dual-Ion Battery,” recently appeared in Advanced Energy Materials (IF=16.146).

The discovery is particularly important given rising battery demand and existing LIB technology, which is reaching its limit in specific energy (by weight) and energy density (by volume).

LIBs are widely used in portable electronic devices, electric vehicles and renewable energy systems. Battery disposal creates major environmental problems, since most batteries contain toxic metals in their electrodes. According to the Freedonia Group, world battery demand is expected to rise 7.7% annually, reaching US$120 billion in 2019………http://www.eurekalert.org/pub_releases/2016-03/caos-crd032416.php
