In this study, the Li-ion batteries temperature increase during the discharge process was measured empirically and evaluated using numerical simulation. Moreover, the battery packs cooling using the water, air and water-nano composition fluids such as water-alumina, water-copper oxide, and water-gold was studied through numerical simulation. Accordingly, the battery cooling was simulated by CFD...
For the past decade the lithium-ion battery has had great success in powering many of our rechargeable energy needs. It’s ability to hold more energy than other conventional batteries is what has kept it at the top of the battery pyramid for more than a decade. However, to create a more sustainable future, scientists and engineers have continued to search for a battery technology that could one...
battery pack is the main energy storage element, and directly affects the performance of electric vehicle. this paper selects the forced air cooling of horizontal battery pack as the study object, and researches the heat dissipation performance of different operating conditions with fleunt software. results indicate that: according to the four kinds of transient state conditions and steady stat...
Lithium-oxygen chemistry offers the highest energy density for a rechargeable system as a "lithium-air battery". Most studies of lithium-air batteries have focused on demonstrating battery operations in pure oxygen conditions; such a battery should technically be described as a "lithium-dioxygen battery". Consequently, the next step for the lithium-"air" battery is to understand how the reactio...
Rechargeable non-aqueous Li-air battery technology offers potential advantages over other existing battery systems in terms of specific energy and energy density, which could enable the driving range of an electric vehicle to be comparable to that of gasoline vehicles. Development of efficient cathode catalysts and stable electrolytes for the Li-air battery has been intensively investigated for...
The lithium-air battery has been proposed as the next-generation energy-storage device with a much higher energy density compared with the conventional lithium-ion battery. However, lithium-air batteries currently suffer enormous problems including parasitic reactions, low recyclability in air, degradation, and leakage of liquid electrolyte. Besides, they are designed into a rigid bulk structur...
This paper discusses the theory and experiments of heating and air cooling of battery modules. The heating mechanisms are shown first. Then, cooling of a single battery is examined. Optimum air flow speed is discussed. © 2014 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the Scientific Committee of IICST 2014.
The recently developed solid oxide metal-air redox battery is a new technology capable of high-rate chemistry. Here we report that the performance, reversibility and stability of a solid oxide iron-air redox battery can be significantly improved by nanostructuring energy storage materials from a carbothermic reaction.
A cooperative behavior of Zn(2+) and Li(+) to conduct charges in a Zn-LiFePO4 battery is disclosed. When Li(+) dissolves into the electrolyte, Zn(2+) would deposit, and vice versa. In light of this cooperative behavior, the battery can be viewed as a super hybrid system, which combines the strong points of Zn-air battery, lithium-ion battery and redox-flow cell.
