Review on Li-Ion Battery vs Nickel Metal Hydride Battery in EV

Abstract

Currently, electric cars are receiving a lot of attention because of their low fuel consumption and pollution-free nature. The efficiency of electric vehicles is constantly being improved via a variety of studies and applications. The battery is a significant portion of an electric vehicle’s overall component count. Because the electric vehicle’s battery acts like the vehicle’s heart, battery performance and efficiency in electric vehicles (EVs) are examined in this research.

First case of nickel-metal hydride battery ingestion in child

“…NiMH batteries have a high metal content, in which it is composed of a cathode of nickel oxide hydroxide (NiOOH), an anode of hydrogen absorbing alloys (MH 2 ), a potassium hydroxide (KOH) electrolyte and a high content of other rare earth elements such as lanthanum and cobalt [ 1 ]. The overall reaction is shown as follows:…”

Polycyclic Aromatic Hydrocarbons as Anode Materials in Lithium-Ion Batteries: A DFT Study

“…The cathode materials for alkali-metal-based batteries are normally organic cathodes and metal oxides with a layered structure or a spinel structure. − The selection of a suitable anode material is perplexing because it should fulfill the criteria such as compatibility, high reversible discharge capacity, high true density, packing density, low cost, availability, and dimensional and mechanical stability . The alkali metals Li, Na, and K have gained more attention as the most promising anode materials for the next-generation high-energy rechargeable batteries. , The alkali-metal-based batteries can replace other high-quality rechargeable batteries such as lead acid batteries and nickel-cadmium or nickel-metal hydride batteries in terms of capacity, self-discharge characteristics, and internal resistance. − On the basis of the electrodes, the nature of the electrolyte, and the physical state, several schemes were proposed for the classification of lithium-based batteries. Among various kinds of electrochemical batteries, lithium-ion batteries (LIBs) launched in 1991 are considered as the prominent secondary batteries where both the electrodes are intercalation materials.…”

“…Such rings do not show V min points and correspond to the most electron-deficient region/s of the molecule. Among the selected PAHs, the acenes: anthracene (3), pentacene (10), and heptacene (12) show only one R s , located at the central hexagonal ring, whereas phenanthrene (4), pyrene (5), chrysene (6), and bisanthene (16) show the presence of two R s which are identical due to symmetry. Bisanthene is a polyarene with the molecular formula C 28 H 14 , which can be described with two anthracene moieties separated by two R e rings.…”

“…distribution in rings which belongs to the R b category. The MESP analysis of polyacenes such as tetracene (8), pentacene (10), hexacene (11), and heptacene (12) show the presence of fused R b rings among which the innermost R b is more electron rich compared to other R b rings (Table S2). According to the MESP topology of polyacenes with an even number of hexagonal rings (8 and 10), the central portion is R n type, while R s description is the most suited for the center ring of acenes having an odd number of hexagonal rings (10 and 12).…”

Study of Friction and Wear Behavior of Graphene-Reinforced AA7075 Nanocomposites by Machine Learning

“…Graphene lasts a long time since it has a high mechanical strength [6]. Using the nanoindentation method of atomic force microscopy, Arun et al [7] determined that graphene is the most robust material yet quantified for monolayer graphene membranes. They found that the tensile strength of defect-free monolayer graphene was 131 GPa, whereas Young's modulus (E) was 1 MPa.…”
