Rechargeable batteries made from low-cost and abundant materials operating in safe aqueous electrolytes are attractive for large-scale energy storage. Sodium-ion battery is considered as a potential alternative of current lithium-ion battery. As sodium-intercalation compounds suitable for aqueous batteries are limited, we adopt a novel concept of Li(+)/Na(+) mixed-ion electrolytes to create two...

Battery thermal management systems (BTMSs) are expected to keep the battery temperature at a moderate level (?30 °C) minimize thermally exacerbated degradation. However, during fast charging, strong cooling system is required restrict rise of Li-ion batteries (LiBs), which significantly increases cost and weight packs, induces large variation inside battery. In this work we find that all these ...

Abstract Electric vehicles are gaining increasing room in the global market, since they seen amongst most promising solutions to cope with growing concerns related climate change and environmental pollution. The successful evolution of transportation sector towards electro-mobility depends on battery chemistry technology, its impacts. However, poor availability data at commercial production sca...

Fossil fuels are our major source of energy, but they are depleting quickly. They also create major environmental issues such as climate change by causing the emission of carbon dioxide and other greenhouse gases. As a result, clean and renewable sources of energy such as solar, nuclear and wind are being considered as alternatives to fossil fuels. Some renewable energy sources are intermittent...

A bilayered cellulose-based separator design is presented that can enhance the electrochemical performance of lithium-ion batteries (LIBs) via the inclusion of a porous redox-active layer. The proposed flexible redox-active separator consists of a mesoporous, insulating nanocellulose fiber layer that provides the necessary insulation between the electrodes and a porous, conductive, and redox-ac...

34 T he materials in anodes and cathodes within a lithium-ion battery affect voltage, capacity, and battery life. When a battery is discharging, the lithium ions move from the anode into the cathode. During the charging process, that movement is reversed. Electrolytes conduct the lithium ions and serve as a carrier between the cathode and the anode when electric currents pass through an externa...

Purpose: Polarization voltage of the lithium-ion battery is an important parameter that has direct influence on battery performance. The paper aims to analyze the impedance characteristics of the lithium-ion battery based on EIS data. Design/methodology/approach: The effects of currents, initial SOC of the battery on charge polarization voltage are investigated, which is approximately linear fu...
