Olivine LiFePO4 has received much attention recently as a promising storage compound for cathodes in lithium ion batteries. It has an energy density similar to that of LiCoO 2, the current industry standard for cathode materials in lithium ion batteries, but with a lower raw materials cost and an increased level of safety. An inherent limitation of LiFePO4 acknowledged by researchers studying t...

The negative impact of the automotive industry on climate change can be tackled by changing from fossil driven vehicles towards battery electric vehicles with no tailpipe emissions. However their adoption mainly depends on the willingness to pay for the extra cost of the traction battery. The goal of this paper is to predict the cost of a battery pack in 2030 when considering two aspects: first...

DOI: 10.1002/aenm.201301329 Energy conversion and storage, [ 1–3 ] as the two most important technologies for energy, are usually two distinct processes that are performed by using two different and separated physical units, such as a piezoelectric nanogenerator and lithium-ion battery. [ 4–9 ] Recently, we presented a novel fundamental mechanism that directly hybridizes the two processes into ...

High performance rechargeable batteries are urgently demanded for future energy storage systems. Here, we adopted a lithium-carbon battery configuration. Instead of using carbon materials as the surface provider for lithium-ion adsorption and desorption, we realized induced fluorination of carbon nanotube array (CNTA) paper cathodes, with the source of fluoride ions from electrolytes, by an in-...

One of the key objectives in the realm of flexible electronics and flexible power sources is to achieve large-area, low-cost, scalable production of flexible systems. In this thesis we propose a new Li-ion battery architecture in a fiber form that could be the building block to large-area, conformal, flexible power sources, achieved through fiber thermal drawing. This architecture is based on t...

Lithium ion batteries as a power source are dominating in portable electronics, penetrating the electric vehicle market, and on the verge of entering the utility market for grid-energy storage. Depending on the application, trade-offs among the various performance parameters-energy, power, cycle life, cost, safety, and environmental impact-are often needed, which are linked to severe materials ...

Nitrogen-doped flexible carbon foam was used to fabricate a lithium sulfur battery. The stability and rate performance of the battery were evaluated. The battery with carbon foam calcined at 800 °C displayed superior stability compared with other tested batteries. Battery performance was closely related to the foam structure and component. However, good rate performance was achieved with the fo...
