“…Several literature reviews describe a lifespan range between 15000-20000 cycles for LTO cells, as highlighted in [6,30,35,36,37,39 ]. Recently, LTO manufacturers also affirm the possibility to use an LTO cell at 4 C-rate charge/discharge for 15000 cycles [39].…”

density are necessary for grid-level frequency regulation, [3] hybrid electric vehicles, [4] material handling equipment, [5] etc. Nevertheless, seldom rechargeable ALIBs or non-aqueous lithium-ion batteries (LIBs) can achieve high power density at low temperatures. [6] Compared with non-aqueous electrolytes, aqueous electrolytes with low viscosity and high safety have intrinsic advantages under low temperatures and high rate circumstances. [2,7] Therefore, ALIBs have the potential to maintain excellent capacity and power densities at low temperatures, as long as the following two problems are settled: i) the high freezing point of aqueous solutions causing the dramatic decline in the conductivities of electrolytes at low temperatures; ii) the sluggish kinetics derived from both de-solvation and bulk diffusion steps impeding lithium ions fast de-/intercalation in the electrode materials. [7c] To tackle these thorny problems, scientists have come up with some strategies from a wide perspective. Generally, organic solvents with high polarities, such as ethylene glycol, [8] 1,3-dioxolane, [9] and dimethyl sulfoxide, [10] can break the hydrogen bonds (HBs) network of water and have been used to decrease the freezing point of electrolytes. However, blending with organic solvents would make aqueous electrolytes a lower ionic conductivity, higher toxicity, and combustibility. On the other hand, adding salts with high solubilities, such as LiCl and LiTFSI, is considered a safe, effective, and promising route for building low-temperature electrolytes of ALIBs. [6d,11] However, the unsatisfactory specific capacity of electrode materials even at the low current density (≤0.2 A g -1 ), such as LiMn 2 O 4 (63 mAh g -1 , −40 °C), [11b] LiCoO 2 (65 mAh g -1 , −40 °C), [11a] LiTi 2 (PO 4 ) 3 (65 mAh g -1 , −50 °C), [10] and LiFePO 4 (36 mAh g -1 , −20 °C), [8] greatly limits the rapid development of ALIBs. Even though some strategies (nanosize and surface modification) to improve the low-temperature kinetics of electrode materials in non-aqueous LIBs are worth referring and trying, [12] significant progress is rarely reported, which should be attributed to the sluggish electrochemical reaction nature of intercalation compounds at low temperatures.Herein, we propose an ultra-low temperature aqueous lithium ion-bromine battery (ALBB) realized by a tailored functionalized electrolyte (TFE) consisting of lithium bromide (LiBr) and tetrapropylammonium bromide (TPABr), which can keep liquid and possess high conductivity even at the Aqueous lithium-ion batteries are normally limited at low temperatures, because of the consequent low conductivity of electrolytes and the sluggish kinetics of electrode materials. Herein, a high-performance ultra-low temperature aqueous lithium ion-bromine battery (ALBB) realized by a tailored functionalized electrolyte (TFE) consisting of lithium bromide and tetrapropylammonium bromide (TPABr) is reported, which can maintain liquid state with high conductivity (1.89 mS cm −1 ) at −60 °C.

Environmental impact of economic activities: Decoupling perspective of Singapore using log mean Divisia index decomposition technique

2023

View full text Add to dashboard Cite

The chase for economic growth results in global environmental degradation, threatening the socioeconomic aspects of human lives. Singapore is a global economic player, transforming its rural setup into an urban structure to achieve higher economic growth (EG). However, the drive for EG drastically affected its environmental quality. In this respect, the present study analyzes the relationship between Singapore's economic activities and environmental quality. This study uses the Tapio decoupling indicator, Kaya Identity, and the Log Mean Divisia Index (LMDI) decomposition techniques to assess the relationships between these paramount factors from 1990 to 2016. The LMDI analysis reveals that EG and population are the main contributors to carbon emissions (CE), whereas carbon intensity reduces the environmental impact. However, energy intensity and energy structure have depicted mixed effects on CE. Further, Tapio analysis reveals that Singapore has experienced strong decoupling (SD) in most study years. Additionally, expensive negative decoupling (END), weak decoupling (WD), and strong negative decoupling (SND) were also observed during the study period. An expanded decomposition analysis reveals that population and EG deteriorate environmental quality in Singapore. While carbon intensity is the critical driver that strengthens the decoupling progress, energy intensity and structure depict a mixed effect on the decoupling process.
