Samsung Dramatically Increases Battery Capacity

Samsung researchers have developed a new technology that enables them to coat silicon battery cathodes with high crystal graphene. This means that they can now virtually double the capacity of lithium-ion batteries! This energy density increase could almost double the range of electric vehicles without adding a single pound of weight. This […]

Researchers Add Compounds to Electrolyte to Prevent Dendrite Growth

Those doggone dendrites are the bane of battery boffins working on otherwise promising lithium metal anodes. Now a group of researchers from SLAC, Stanford and MIT have discovered that adding lithium polysulfide and lithium nitrate to an ether-based electrolyte can prevent dendrite growth and minimize electrolyte decomposition. Professor Yi Cui, […]
