Rechargeable lithium-ion battery technology dominates the portable electronics market following the rapid growth in demand since the introduction of the first, commercial lithium-ion battery by Sony in 1990 [1]. Motivated by concerns for global warming and environmental degradation, researchers have focused on extending the use of rechargeable lithium-ion batteries to large-scale applications. ...

A superfine Li0.33La0.557TiO₃ (LLTO, 69.4 nm) was successfully synthesized by a facile solvent-thermal method to enhance the electrochemical properties of the lithium-ion battery separator. Co-axial nanofiber of cellulose and Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) was prepared by a co-axial electrospinning technique, in which the shell material was PVDF-HFP and the core was...

We evaluate miniature batteries as potential power sources for advanced wildlife telemetry tags. These tags are often based on integrated UHF transceivers that are designed for wireless sensor networks and that consume 18-85mA while receiving or transmitting. This current drain is challenging for many types of miniature batteries. We evaluate batteries both on actual tags and in a specialized s...

Recovering kinetic, transport, and thermodynamic parameters is a key task in the development of battery models. This task is complicated because of the lack of informative experimental data and because of the complexity of the associated partial differential equation models. We present a computational framework that combines a variety of techniques to investigate the effects that different sour...

Thermally sensitive binder (TSB) is developed as an internal safety mechanism of lithium-ion battery (LIB). The TSB is a polymer blend of poly(vinylidene fluoride) (PVDF) and poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP). Compared with regular PVDF binder, the softening and swelling of TSB are more pronounced when temperature is above 110 8C. With the TSB, the cycling performance ...

Lithium battery separators play a critical role in the performance and safety of lithium batteries. In this work, four kinds polymer particle adhesives (G1–G4) for were synthesized via dispersion polymerization, using styrene, butyl acrylate acrylonitrile as monomers. The size/size distributions, morphologies glass transition temperatures (Tg) explored laser size analysis, scanning electron mic...
