Low-Cost High-Energy Potassium Cathode

Electrochemical Characterization of Low-Cost Lithium-Iron Orthosilicate Samples as Cathode Materials of Lithium-Ion Battery

Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...

Spinel LiNi0.5Mn1.5O4 Cathode for High-Energy Aqueous Lithium-Ion Batteries

DOI: 10.1002/aenm.201600922 considering the overpotential during charge process. Recently, Yamada et al. reported that LiNi0.5Mn1.5O4 can only reversibly provide capacity of ≈75 mA h g−1 in the more concentrated hydrate melt electrolytes (≈30 mol kg−1), which is 50% of theoretical capacity.[14] The oxygen evolution side reaction also largely significantly reduce the coulombic efficiency. In add...

Low-cost High Performance Low-field MRI

Envisioning the healthcare technology of tomorrow requires one to break from the mainstream and explore alternative approaches to develop accessible, ubiquitous diagnostic tools. In the field of magnetic resonance imaging (MRI), despite considerable improvements in imaging quality and speed, the underlying technology remains remarkably unchanged compared to the first generation scanners that em...

High Efficiency and Low Cost LINAC System Design Suitable for High Energy Ion Implanters

A new radio frequency (rf) linear accelerator (LINAC) system with high efficiency has been developed by AIBT. The general designs of such a rf LINAC system are briefly discussed. This system includes a plurality of resonators each including an inductor circuit that is connected to at least two rf electrodes. Detailed designs of a system where two of the adjacent rf electrodes are connected to t...
