LiCoPO4 cathode from a CoHPO4·xH2O nanoplate precursor for high voltage Li-ion batteries
A highly crystalline LiCoPO4/C cathode material has been synthesized without noticeable impurities via a single step solid-state reaction using CoHPO4·xH2O nanoplate as a precursor obtained by a simple precipitation route. The LiCoPO4/C cathode delivered a specific capacity of 125 mAhg(-1) at a charge/discharge rate of C/10. The nanoplate precursor and final LiCoPO4/C cathode have been characte...
متن کاملMembrane insertion of a potassium-channel voltage sensor.
The mechanism of voltage gating in K+ channels is controversial. The paddle model posits that highly charged voltage-sensor domains move relatively freely across the lipid bilayer in response to membrane depolarization; competing models picture the charged S4 voltage-sensor helix as being shielded from lipid contact by other parts of the protein. We measured the apparent free energy of membrane...
متن کاملThianthrene-functionalized polynorbornenes as high-voltage materials for organic cathode-based dual-ion batteries.
Thianthrene-functionalized polynorbornenes were investigated as high-voltage organic cathode materials for dual-ion cells. The polymers show reversible oxidation reactions in solution and as a solid in composite electrodes. Constant current investigations displayed a capacity of up to 66 mA h g(-1) at a high potential of 4.1 V vs. Li/Li(+).
متن کاملUltrathin surface modification by atomic layer deposition on high voltage cathode LiNi0.5Mn1.5O4 for lithium ion batteries
Atomic layer deposition (ALD) has been employed to modify the surface of high voltage cathode LiNi0.5Mn1.5O4 by coating ultrathin Al2O3 layer on the electrodes. The ultrathin layer of Al2O3 can suppress the undesirable reactions during cycling, while maintaining the electron and ion conductivity of the electrode. The ALD Al2O3 coated LiNi0.5Mn1.5O4 showed remarkable improvement over bare LiNi0....

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...
