The overdischarge can significantly degrade a lithium-ion (Li-ion) battery's lifetime. Therefore, it is important to detect the and prevent severe damage of Li-ion battery. Depending on battery technology, there minimum voltage (cutoff voltage) that allowed be discharged in common practice. Once below cutoff voltage, considered as overdischarge. However, will not lead immediate failure battery,...

The development of Li-excess disordered-rocksalt (DRX) cathodes for Li-ion batteries and interpretation through the framework percolation theory Li diffusion have steered researchers to consider “Li-excess” (x > 1.1 in LixTM2−xO2; TM = transition metal) as being critical achieving high performance. It is shown that this not necessary Mn-rich DRX-cathodes demonstrated by Li1.05Mn0.90Nb0.05O2 Li1...

This paper presents an applicable health monitoring method for Li-ion batteries based on profust reliability theory. The word “profust” derives from “probability” and “fuzzy-state”, which means that the profust reliability theory is a kind of fuzzy reliability theory based on probability assumption and fuzzy-state assumption. It defines a concept of transition from fuzzy success to fuzzy failur...

New energy industry including electric vehicles and large-scale energy storage in smart grids requires energy storage systems of good safety, high reliability, high energy density and low cost. Here a coated Li metal is used as anode for an aqueous rechargeable lithium battery (ARLB) combining LiMn2O4 as cathode and 0.5 mol l(-1) Li2SO4 aqueous solution as electrolyte. Due to the "cross-over" e...

Topological state of matter and lithium batteries are currently two hot topics in science and technology. Here we combine these two by exploring the possibility of using all-carbon-based porous topological semimetal for lithium battery anode material. Based on density-functional theory and the cluster-expansion method, we find that the recently identified topological semimetal bco-C16 is a prom...

Among the "beyond Li-ion" battery chemistries, nonaqueous Li-O2 batteries have the highest theoretical specific energy and, as a result, have attracted significant research attention over the past decade. A critical scientific challenge facing nonaqueous Li-O2 batteries is the electronically insulating nature of the primary discharge product, lithium peroxide, which passivates the battery catho...

High-Energy Li-Ion Batteries In article number 2203841, Xuning Feng, Li Wang, Minggao Ouyang, and co-workers focus on the catastrophic thermal failure of high-energy Li-ion batteries, which tend to behave more violently in accidents with fire explosions. Based a comprehensive review, main challenges, as well promising safety design routes overcome intrinsic trade-off between energy density batt...

Batteries help advance technologies ranging from portable electronics to renewable power systems and environmentally friendly vehicles. One such technology is the hybrid electric vehicle (HEV), which uses a battery and an electric motor in conjunction with a combustion engine to increase fuel effi ciency. For HEV applications, nickel metal hydride (Ni-MH) battery chemistry is presently the norm...

This paper describes a new adaptive neuro-fuzzy inference system (ANFIS) model to estimate accurately the battery residual capacity (BRC) of the lithium-ion (Li-ion) battery for modern electric vehicles (EVs). The key to this model is to adopt newly both the discharged/regenerative capacity distributions and the temperature distributions as the inputs and the state of available capacity (SOAC) ...

Typical layered transition-metal chalcogenide materials, in particular layered molybdenum disulfide (MoS2) nanocomposites, have attracted increasing attention in recent years due to their excellent chemical and physical properties in various research fieldsHere, a general overview of synthetic MoS2 based nanocomposites via different preparation approaches and their applications in energy storag...
