The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—in electric vehicles, for example. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. Here, the use of an ultrathin (?1.2

Battery researchers at the University of Eastern Finland have developed a self-standing mesoporous silicon (Si) film anode for lithium-ion batteries. This film electrode does not need carbon additives and binders to connect particles as do typical slurry-based electrodes, but it still exhibits excellent battery performance.

Dendrites and whiskers are holding back the widespread use of lithium metal batteries, which have higher energy density than their commonly used lithium-ion counterparts. The team’s findings include videos that show the step-by-step growth of a whisker inside a nanosized lithium metal battery specially designed for the study.

New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. Traditionally, graphite is used for the anode of a lithium-ion battery, but this carbon material has major limitations.

Lithium-ion batteries could benefit from a theoretical model created at Rice University and Lawrence Livermore National Laboratory that predicts how carbon-based anodes will perform. It doesn’t exactly tell you how strong the person will be, but it gives you some idea. —Boris Yakobson. Yuanyue Liu, Y. 113.028304.

The idea, reported in a paper in the journal Energy Storage Materials has potential for large scale applications, including storage of solar and wind energy. The question is if aluminum batteries could eventually replace lithium-ion batteries. Of course, we hope that they can.
