Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...

3 types of lithium-ion capacitors using Nb2CTx-CNT as one electrode were tested. The highest volumetric energy density of 50e70 Wh/L was achieved. Energy density of symmetric cell exceeds that of lithium titanate/acti-

Introduction With the goal of promoting energy conservation and exploring forms of energy alternative to petrified sources, as well as of reducing environmental burden, much effort has been spent on developing new breeds of vehicles. These include Hybrid vehicles (HV) that run on a combined system of a fossil fuel engine and an electric motor, Plug-in HVs (PHVs) that allow recharging of the in-...

Li-ion batteries were first commercialized by Sony in 1991 and have been used widely in portable electronic devices, electric vehicles and grid applications. Although Li-ion batteries have achieved a phenomenon commercial success and become so pervasive and indispensable in our modern life, their development has been sluggish and fallen way behind the rapid advancement of electronic technologie...

Degradation mechanisms such as lithium plating, growth of the passivated surface film layer on the electrodes and loss of both recyclable lithium ions and electrode material adversely affect the longevity of the lithium ion battery. The anode electrode is very vulnerable to these degradation mechanisms. In this paper, the most common aging mechanisms occurring at the anode during the operation ...

Restacked MoS(2) with enlarged c lattice parameter and surface area was prepared by exfoliation and restacking process, exhibiting high reversible lithium storage capacity and superior rate capability as anode material for lithium ion batteries.

A SnO2-N-doped graphene (SnO2-NG) composite is synthesized by a rapid, facile, one-step microwave-assisted solvothermal method. The composite exhibits excellent lithium storage capability and high durability, and is a promising anode material for lithium ion batteries.

It is estimated that over 90% of people own a mobile phone. Although rare, lithium-ion battery explosions can cause varying degrees of thermal burn injury. Recently, selective enzymatic debridement has gained importance in the management of burn patients, thanks to its simplicity, minimum invasiveness and safety. In this work, we describe a case of a burn injury caused by the explosion of a lit...

Nickel Cadmium batteries are popular because they have a relatively low cost and offer a mature technology. Nickel Metal Hydride batteries have improved volumetric efficiency and have less environmental concerns than Nickel Cadmium. Lithium-Ion batteries are emerging as a leader in the portable market due to their high energy density. Lithium-Ion batteries have the highest initial cost, however...

Sulfur-rich lithium polysulfidophosphates (LPSPs) act as an enabler for long-lasting and efficient lithium-sulfur batteries. LPSPs have ionic conductivities of 3.0×10(-5)  S cm(-1) at 25 °C, which is 8 orders of magnitude higher than that of Li2S. The high lithium ion conductivity imparts excellent cycling performance, and the batteries are configured in an all-solid state, which promises safe ...
