“…These are significant and attributable to the numerous assumptions and simplifications in the process and assessment model and the often insufficient information about inputs and emissions. Also, battery chemistries are developing, and low cobalt NMC cathodes (NMC 622 and NMC 811 are already on the rise, expected to substitute NMC 111 in near future (Shobana, 2019). Energy densities are expected to increase further while the energy and GHG intensity of the cell manufacturing process is decreasing (Emilsson & Dahllöf, 2019).…”

On the basis of a review of existing life cycle assessment studies on lithium‐ion battery recycling, we parametrize process models of state‐of‐the‐art pyrometallurgical and hydrometallurgical recycling, enabling their application to different cell chemistries, including beyond‐lithium batteries such as sodium‐ion batteries. These processes are used as benchmark for evaluating an advanced hydrometallurgical recycling process, which is modeled on the basis of primary data obtained from a recycling company, quantifying the potential reduction of environmental impacts that can be achieved by the recycling of different cell chemistries. Depending on the cell chemistry, recycling can reduce significantly the potential environmental impacts of battery production. The highest benefit is obtained via advanced hydrometallurgical treatment for lithium nickel manganese cobalt oxide and lithium nickel cobalt aluminum oxide‐type batteries, mainly because of the recovery of cobalt and nickel. Especially under resource depletion aspects, recycling of these cells can reduce their impact to an extent that even leads to a lower “net impact” than that of cells made from majorly abundant and cheap materials like lithium iron phosphate, which shows a more favorable performance when recycling is disregarded. For these cells, recycling does not necessarily provide benefits but can rather cause additional environmental impacts. This indicates that maximum material recovery might not always be favorable under environmental aspects and that, especially for the final hydrometallurgical treatment, the process would need to be adapted to the specific cell chemistry, if one wants to obtain maximum environmental benefit.

“…After several charging and discharging, the energy holding and emitting capacity of a LiB decrease due to voltage fade [371]. Usually, the metal oxide coated cathode material is the root of voltage fading [372]. Zou et al [373] probed the advantages of using Li-rich layered cathode [374], [375] in reducing the voltage fade of LiBs.…”

The advancement and popularity of smartphones have made it an essential and all-purpose device. But lack of advancement in battery technology has held back its optimum potential. Therefore, considering its scarcity, optimal use and efficient management of energy are crucial in a smartphone. For that, a fair understanding of a smartphone's energy consumption factors is necessary for both users and device manufacturers, along with other stakeholders in the smartphone ecosystem. It is important to assess how much of the device's energy is consumed by which components and under what circumstances. This paper provides a generalized, but detailed analysis of the power consumption causes (internal and external) of a smartphone and also offers suggestive measures to minimize the consumption for each factor. The main contribution of this paper is four comprehensive literature reviews on: 1) smartphone's power consumption assessment and estimation (including power consumption analysis and modelling); 2) power consumption management for smartphones (including energy-saving methods and techniques); 3) state-of-the-art of the research and commercial developments of smartphone batteries (including alternative power sources); and 4) mitigating the hazardous issues of smartphones' batteries (with a details explanation of the issues). The research works are further subcategorized based on different research and solution approaches. A good number of recent empirical research works are considered for this comprehensive review, and each of them is succinctly analysed and discussed.

“…Engineering of artificial solid-electrolyte interfaces in lithium ion batteries are a part of common strategy to improve a wide span of characteristics, including capacity, rate capability and longer cycle life. [1][2][3] By using an artificial solid-electrolyte interface for layered intercalation cathodes such as LiCoO2 and LiNi1-y-zMnyCozO2, the decay of the electrochemical performance can be decelerated and the power performance enhanced. [4,5] This is possible due to the suppression of redox-active metal dissolution from the cathode into the electrolyte and prevention of the formation of a resistive native layer at the cathode-electrolyte interface.…”

Protective coatings applied to cathodes help to overcome interface stability issues and extend the cycle life of Li-ion batteries. However, within 3D cathode composites it is difficult to isolate the effect of the coating because of the additives and non-ideal interfaces. In this study we investigate niobium oxide (NbOx) as cathode coating in a thin-film model system, which provides simple access to the cathode-coating-electrolyte interface. The conformal NbOx coating was applied by atomic layer deposition (ALD) onto thin-film LiCoO2 cathodes. The cathode/coating stacks were annealed to lithiate the NbOx and ensure sufficient ionic conductivity. A range of different coating thicknesses were investigated to improve the electrochemical cycling with respect to the uncoated cathode. At a NbOx thickness of 30 nm, the cells retained 80% of the initial capacity after 493 cycles at 10 C, more than doubling the cycle life of the uncoated cathode film. At the same thickness, the coating also showed a positive impact on the rate performance of the cathode: 47% of the initial capacity was accessible even at ultrahigh charge-discharge rates of 100 C. Using impedance spectroscopy measurements, we found that the enhanced performance is due to suppressed interfacial resistance growth during cycling. Elemental analysis using TOF-SIMS and XPS further revealed a bulk and surface contribution of the NbOx coating. These results show that in situ lithiated ALD NbOx can significantly improve the performance of layered oxide cathodes by enhancing interfacial charge transfer and inhibiting surface degradation of the cathode, resulting in better rate performance and cycle life.
