Sub-1 nm nanowires (SNWs) can not only be processed like polymers due to their polymer-analogue properties but also show multifunctions owing well-manipulated compositions and structures. Rationally designed engineered multicomponent heterostructure SNWs further enhance multifunction performance while it is very challenging achieve such at sub-nanoscale. Herein, we synthesized Bi2O3-polyoxometa...

Polymer electrolyte based on Nafion-117 membranes in the Li+ form with intercalated 1,3-dioxolane-dimethoxyethane solvent mixtures (DOL-DME) has been obtained. The obtained Nafion-Li+-DOL-DME characterized by DSC analysis, IR- and impedance spectroscopy. uptake of membrane DOL-DME mixture amounts to 1.9. is an ionic conductivity ~10−7 S cm−1 at room temperature. comparative study electrochemica...

Lithium-ion (Li-ion) batteries are favored in hybrid-electric vehicles and electric vehicles for their outstanding power characteristics. In this paper the energy loss due to electrical contact resistance (ECR) at the interface of electrodes and currentcollector bars in Li-ion battery assemblies is investigated for the first time. ECR is a direct result of contact surface imperfections and acts...

The shuttle effect is one of the most notable challenges in fundamental research and practical use lithium-sulfur (Li-S) batteries, especially within high-polarity electrolytes containing enriched polysulfides. Herein, we demonstrate a proof-of-concept study showing that issue can be resolved by constructing liquid-state/quasi-solid-state (LS/QSS) two-phase interface composed QSS electrolyte we...

Li-ion cell thermal-runaway failures can occur due to poor cell or battery-pack design (electrochemical or mechanical), manufacturing flaws, external abuse, and poor charger or system design. Fortunately, a procedure for detecting future failures shows promise. Internal cell faults continue to lead to thermal runaway failures in Li-ion battery packs used in the field. Though these events are ra...

Aiming to the defect of expandability and reliability of Li-Ion battery of protection circuit, the multisection series connection Li-ion battery management system was designed based on X3100 chip. The hardware and software design of the system was elaborated. The system can realize the measure, management and auto-protection for various parameters and complete the calculation for tens of comman...

The possibility of achieving high-energy, long-life storage batteries has tremendous scientific and technological significance. A prime example is the Li−S cell, which can offer a 3−5-fold increase in energy density compared with conventional Liion cells, at lower cost. Despite significant recent advances, there are challenges to its wide-scale implementation. Upon sulfur reduction, intermediat...

Lithium-sulphur batteries are under intense research due to the high specific capacity and low cost. However, several problems limit their commercialization. One of them is the insulating nature of sulphur, which necessitates a large amount of conductive agent and binder in the cathode, reducing the effective sulphur load as well as the energy density. Here we introduce a redox mediator, cobalt...

Here we report an approach to roll out Li-ion battery components from silicon chips by a continuous and repeatable etch-infiltrate-peel cycle. Vertically aligned silicon nanowires etched from recycled silicon wafers are captured in a polymer matrix that operates as Li(+) gel-electrolyte and electrode separator and peeled off to make multiple battery devices out of a single wafer. Porous, electr...
