Organic chemistry plays an important role in the development of high-performance rechargeable batteries exceeding Li-ion batteries using LiCoO2 as a cathode-active material. The authors implemented the high-capacity rechargeable batteries using trioxotriangulene (TOT) stable neutral radicals with four-stage redox ability as cathode-active materials. These batteries showed the capacity of 311 A ...

The most important problems of today are meeting the increasing energy needs and avoiding environmental pollution caused by fossil resources usage for production. In addition, decrease in usable water world has become a threat to human health population. Microbial fuel cells (MFC) have more interesting recent years because their potential solve these three problems. Organic inorganic contents w...

Increasing lithium content is shown to be a successful strategy for designing new cathode materials. In layered Li(x)Ni(2-4x/3)Sb(x/3)O2 (x = 1.00-1.15), lithium excess improves both discharge capacity and capacity retention at 1C. Structural studies reveal a complex nanostructure pattern of Li-Sb and Ni-Sb ordering where the interface between these domains forms the correct local configuration...

Lithium metal orthosilicates are attracting a lot of attention owing to their promising prospects as potential high capacity cathode materials for Li-ion batteries. Currently, great efforts are being made in order to achieve the full theoretical specific capacity of 330 mA h g(-1), but many issues remain unsolved (e.g., poor structural and cycling stability), which limit their practical applica...

Microbial fuel cells (MFC) with 30% wet-proofed air cathodes have previously been optimized to have 4 diffusion layers (DLs) in order to limit oxygen transfer into the anode chamber and optimize performance. Newer MFC designs that allow close electrode spacing have a separator that can also reduce oxygen transfer into the anode chamber, and there are many types of carbon wet-proofed materials a...

The development of cathode materials with high capacity and cycle stability is essential to emerging electric-vehicle technologies, however, of serious environmental concern is that materials with these properties developed so far contain the toxic and expensive Co. We report here the Li-rich, Co-free Li1+xMO2 (M = Li, Ni, Mn, Fe) composite cathode material, prepared via a template-free, one-st...
