New aqueous rechargeable lithium battery shows good safety, high
reliability, high energy density and low cost; another post Li-
ion alternative 8 March 2013 |Schematic illustration of the
aqueous rechargeable lithium battery (ARLB) using the coated

Technische Universität Chemnitz in Germany have developed an
aqueous rechargeable lithium battery (ARLB) using coated Li
metal as the anode. In a paper published in Scientific Reports,
the open access journal from the Nature Publishing Group, the
team reports that the ARLB delivers an output voltage of about
4V. The battery shows an energy density of up to 446 Wh
kg-1—about 80% higher than conventional Li-ion batteries, and
much higher than energy densities reported for earlier ARLBs
(30–45 Wh kg-1). The battery, which can be low cost and reliable
in terms of safety, provides another chemist
