Due to their low cost, high abundance and eco-friendly features, Na-ion batteries are becoming alternative choices for rechargeable batteries, especially in large scale applications. Generally, the well-crystallized materials have many advantages over amorphous materials, such as long cycle life, high rate performance and other electrochemical properties. However, the amorphous FePO4 we report ...

The Peukert relationship was originally introduced in 1897 for lead-acid batteries and defines one of the most common parameters for battery performance evaluation. This article assesses its application for lithium-ion batteries. From the performed analysis, we can conclude that the Peukert relationship is suitable in a narrow working range such as limited current range and almost constant work...

INTRODUCTION Electrolytes typically used in lithium batteries consist of a lithium salt dissolved in an organic solvent, or a mixture of these solvents. The solvents fall into two general classes: ethers or alkyl esters of carbonic acid. Because of lower volatility and higher flash point, the organic carbonates are the preferred solvent class in commercial batteries. Propylene carbonate (PC) ha...

Rechargeable batteries are now widely used as the power supply source in many portable electronic equipments such as Laptops, cell phones and digital cameras. Charging circuits depend on the batterys chemistry and the most popular rechargeable batteries are Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), and Lithium-Ion (Li-Ion). This application report discusses the method to charge a Li-I...

Nitrogen-doped activated porous carbon fibres (ACFs) were prepared as anode materials for Na-ion batteries. They exhibit excellent electrochemical performance, especially rate performance. The excellent rate performance is ascribed to the fibre-like morphology and the facilitated charge transfer. The influence of nitrogen functionalities on charge transfer and electrochemical performance of N-d...

BiOI nanosheets are easily synthesized by direct thermal treatment of commercial BiI3 powder, serving as a novel anode material for lithium-ion batteries. A high volumetric capacity of ∼5678 mA h cm(-3) was achieved. This work demonstrates that the BiOI nanosheets hold great promise as high-energy anode material for lithium-ion batteries.

Amorphous Sb2S3 embedded in a conductive graphite matrix is designed for sodium-ion batteries. Owing to the amorphous structure of the active phase and the conductive graphite matrix, the Sb2S3-graphite electrode exhibits a high initial Coulomblic efficiency, a high rate capacity, and stable cycle performance in sodium-ion batteries.
