Pore collapse and regrowth in silicon electrodes for rechargeable batteries.

Structure and composition of an 11 nm thick amorphous silicon (a-Si) thin film anode, capped with 4 nm of alumina are measured, in operando, by neutron reflectivity (NR) and electrochemical impedance spectroscopy in a lithium half-cell. NR data are analyzed to quantify the a-Si thickness and composition at various states of charge over six cycles. The a-Si anode expands and contracts upon lithi...

Rechargeable Batteries

Purpose: The goal of our battery research is to produce an all solid-state, high performance rechargeable cell. Moving to a liquid-free polymer electrolyte eliminates the need for heavy casing material, thus the energy density is increased significantly. In addition, the absence of solvent additives leads to better thermal and chemical stability, broadening the range of applications for which t...

High power rechargeable batteries

Energy and power density are the key figures of merit for most electrochemical energy storage systems. Considerable efforts worldwide have been made to improve the energy density of rechargeable (secondary) batteries, as this is critical for most applications. As the penetration of batteries into ever more demanding applications has increased, power density, the allowed rate of energy transfer ...

Electrodes with high power and high capacity for rechargeable lithium batteries.

New applications such as hybrid electric vehicles and power backup require rechargeable batteries that combine high energy density with high charge and discharge rate capability. Using ab initio computational modeling, we identified useful strategies to design higher rate battery electrodes and tested them on lithium nickel manganese oxide [Li(Ni(0.5)Mn(0.5))O2], a safe, inexpensive material th...

Ion beam-mixed Ge electrodes for high capacity Li rechargeable batteries

Ion beam modification to effect ion beam mixing without changing morphology was investigated as a means to improve the electrochemical performance of Ge thin film electrodes for rechargeable Li batteries. As a result of a minimum tenfold increase in the strength of adhesion of the Ge film to the current collector (substrate), the ion beam-mixed electrodes exhibited stable specific capacities of...
