Lithium batteries have been widely used as a power source for numerous small devices such as mobile phones and laptop computers. Recently, the lithium battery is expected to be used as a power source for electric vehicles. For the electric vehicles application, an improvement of energy and power densities and safety is required. In this review, a brief explanation of structure and mechanism of ...

The initial lithium loss during the formation stage is a critical issue that significantly reduces the specific capacity and energy density of current rechargeable lithium-ion batteries (LIBs). An effective strategy to solve this problem is using electrode prelithiation additives that can work as a secondary lithium source and compensate the initial lithium loss. Herein we show that nanocomposi...

Lithium intercalation or insertion materials have been widely investigated in the search for new electrode materials for use in high-voltage rechargeable batteries.1-6 The first commercial Li-ion rechargeable battery contains the layered materials LiCoO2 (Figure 1) and graphite as the cathode (or positive electrode) and anode (or negative electrode), respectively.7 Although this battery is the ...

Looking for solid state electrolytes with fast lithium ion conduction is an important prerequisite for developing all-solid-state lithium secondary batteries. By combining the simulation techniques in different levels of accuracy, e.g. the bond-valence (BV) method and the density functional theory (DFT), a high-throughput design and optimization scheme is proposed for searching fast lithium ion...

Rapid charge and discharge rates have become an important feature of electrical energy storage devices, but cause dramatic reductions in the energy that can be stored or delivered by most rechargeable batteries (their energy capacity). Supercapacitors do not suffer from this problem, but are restricted to much lower stored energy per mass (energy density) than batteries. A storage technology th...

Lithium metal is an attractive anode material for rechargeable batteries, owing to its high theoretical specific capacity of 3,860mAhg−1. Despite extensive research e orts, there are still many fundamental challenges in using lithium metal in lithium-ion batteries. Most notably, critical information such as its nucleation and growth behaviour remains elusive. Here we explore the nucleation patt...

Rechargeable power sources are an essential element of large-scale energy systems based on renewable sources. One the major challenges in rechargeable battery research is development electrode materials with good performance and low cost. Carbon-based have a wide range properties, high electrical conductivity, overall stability during cycling, making them suitable for batteries, including stati...

Conjugated polymeric molecules have been heralded as promising electrode materials for the next-generation energy-storage technologies owing to their chemical flexibility at the molecular level, environmental benefit, and cost advantage. However, before any practical implementation takes place, the low capacity, poor structural stability, and sluggish ion/electron diffusion kinetics remain the ...
