چکیده
The results of measuring the charge-discharge characteristics solid-state thin-film lithium-ion batteries with a nanocomposite anode based on a-Si(Al) solid solution are presented. charging have feature in form step gentle branch U(t) curve. It has been suggested and substantiated that appearance is related to gradual compensation change hole conductivity electronic one as lithium concentration increases. As result, a-Si(Al)|Ti ohmic contact becomes rectifying, electrons participating Faraday process overcome Schottky barrier. potential growth required maintain galvanostatic charge regime manifests itself Keywords: thin film battery, amorphous silicon, solution, sp 3 hybridization, lithiation,

All-Solid-State Lithium-Ion Batteries with Grafted Ceramic Nanoparticles Dispersed in Solid Polymer Electrolytes.
Lithium-based rechargeable batteries offer superior specific energy and power, and have enabled exponential growth in industries focused on small electronic devices. However, further increases in energy density, for example for electric transportation, face the challenge of harnessing the lithium metal as negative electrode instead of limited-capacity graphite and its heavy copper current colle...
متن کاملIi. Solid State Thin Film Lithium Batteries
Solid state thin film lithium microbatteries fabricated by pulsed-laser deposition (PLD) are suggested. During deposition the following process parameters must be considered, which are laser energy and fluence, laser pulse duration, laser pulse frequency, target composition, background gasses, substrate temperature, target-substrate distance and orientation. The effects of the variations of the...
متن کاملElectrolyte and Solid-Electrolyte Interphase Layer in Lithium-Ion Batteries
The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...
متن کاملTransparent lithium-ion batteries.
Transparent devices have recently attracted substantial attention. Various applications have been demonstrated, including displays, touch screens, and solar cells; however, transparent batteries, a key component in fully integrated transparent devices, have not yet been reported. As battery electrode materials are not transparent and have to be thick enough to store energy, the traditional appr...
متن کاملOrigami lithium-ion batteries.
There are significant challenges in developing deformable devices at the system level that contain integrated, deformable energy storage devices. Here we demonstrate an origami lithium-ion battery that can be deformed at an unprecedented high level, including folding, bending and twisting. Deformability at the system level is enabled using rigid origami, which prescribes a crease pattern such t...
