Energetical Modeling of Lithium-Ion Batteries
2007 IEEE Industry Applications Annual Meeting, 2007All electrochemical batteries are characterized by an electrical behavior which depends on temperature, state of charge and current. In the case of lithium-ion accumulators, the energetical behavior is moreover deeply marked by line effects, due to the porosity of both electrodes. This paper deals with investigations on accurate energetical modeling of

SSNTDs for high energetic heavy ions
Nuclear Tracks, 1981ABSTRACT As SSNTD for Argon ions we investigated CR 39 and a borate glass. The energy resolution of CR 39 was 14 MeV in the region of 150 MeV to 300 MeV. The corresponding value for the borate glass was 2.6 MeV. At a projectile energy of 5.0 MeV/u nuclear charges of 20, 22 and 28 could be resolved.

Energetics of lithium ion battery failure
Journal of Hazardous Materials, 2016The energy released by failure of rechargeable 18-mm diameter by 65-mm long cylindrical (18650) lithium ion cells/batteries was measured in a bomb calorimeter for 4 different commercial cathode chemistries over the full range of charge using a method developed for this purpose. Thermal runaway was induced by electrical resistance (Joule) heating of the

The stopping of energetic ions in solids
Nuclear Instruments and Methods, 1980Abstract A method is presented for the calculation of the stopping of energetic ions in matter (energies above 200 keV/amu). The energy loss to target electrons is evaluated using the local density approximation and Lindhard's theory of a particle stopping in a free electron gas.

On the Energetics of Ions in Carbon and Gold Nanotubes
ChemPhysChem, 2015AbstractWe investigate the insertion of halide and alkali atoms into narrow single‐walled carbon nanotubes with diameters <9 Å by density functional theory; both chiral and non‐chiral tubes are considered. The atoms are stored in the form of ions; the concomitant charge transfer affects the band structure and makes originally semiconducting tubes ...

Cytogenetic effects of energetic ions with shielding
Advances in Space Research, 1998In order to understand the effects of shielding on the induction of biological damages by charged particles, we conducted experiments with accelerated protons (250 MeV) and iron particles (1 GeV/u). Human lymphocytes in vitro were exposed to particle beams through polyethylene with various thickness, and chromosomal aberrations were determined using ...

1985
Numerical data are presented for the ionization potentials of singly, doubly and triply charged atomic ions and also for the electron affinities of atoms. The energy levels of the lowest (n = 2) excited states in hydrogen- and heliumlike atomic ions are also assessed.

Microirradiation of cells with energetic heavy ions
Radiation and Environmental Biophysics, 2004The ion microprobe SNAKE at the Munich 14 MV tandem accelerator achieves beam focussing by a superconducting quadrupole doublet and can make use of a broad range of ions and ion energies, from 20 MeV protons to 200 MeV gold ions. Because of these properties, SNAKE is particularly attractive for biological microbeam experiments.

Energetics of Ion Transport in a Peptide Nanotube
The Journal of Physical Chemistry B, 2007Ion channels constitute an important family of integral membrane proteins responsible for the regulation of ion transport across the cell membrane. Yet, the underlying energetics of the permeation events and how the latter are modulated by the environment, specifically near the mouth of the pore, remain only partially characterized.

Interaction of energetic ions with inhomogeneous solids
Physical Review Letters, 1991We use quantitative chemical mapping and statistical analysis to explore the microscopic consequences of the passage of energetic ions through AlAs/GaAs multilayers. We thus quantitatively characterize and microscopically identify the damage cascades produced by individual 320-keV ${\mathrm{Ga}}^{+}$ ions.
