Engineers use MoS2 nano "sandwich" to improve rechargeable batteries |

Singer's research team discovered that molybdenum flakes can store twice as many lithium atoms or charges as previously reported. Singer added that they also discovered the high capacity lithium of these flakes doesn't last for long, and it will drop after five charges. "This behavior is similar with a lithium-sulfur cell, which uses sulfur in one of its electrodes. "It's well-known that sulfur dissolves in the organic electrolyte of the battery to form intermediate polysulfides which causes vol

Electrolytic calcium hexaboride for high capacity anode of aqueous primary batteries

Using lightweight elements/compounds and employing multi-electron reaction (MER) chemistry are two approaches used to develop high-energy-density materials for batteries. In this work, nanoscaled calcium hexaboride (CaB6) was prepared in one step by the electro-reduction of solid calcium borate (CaB2O4) in molten CaCl2–NaCl. CaB2O4 was synthesized by a simple co-precipitation method. It was revealed that the electrolytic CaB6 delivers a specific capacity of 2400 mA h g−1 in 30% KOH solution thro

Canada found that silicon nanoparticles can increase the storage capacity of lithium batteries by 10 times

There are abundant reserves of silicon. Si and Li can form a Li4.4Si structural arrangement, with a theoretical specific energy of 4200mAh/g. That is almost ten-times higher than that of the lithium-ion battery currently in use. In the present day, silicon materials are used in lithium-ion cells primarily for two reasons. One way is to add nano-silicon to anode materials to create a carbon-silicon anode. To improve the performance, organosilicon compounds can be added to the electrolyte. The Un

Application of graphene in lithium-ion batteries

The unique physical and chemical characteristics of graphene make graphene a great candidate for research in electrode materials. With different applications, graphene can be classified into three types: application of graphene to lithium-ion cells, application of anode material, and any other application. Application graphene to cathode materials Cathode materials for lithium-ion batteries must have high reversible potential, stable and large potential, low cost, and no toxicities. LiFePO4 (l
