lithium-ion battery (LIB) is at the forefront of energy research. Over four decades of research and development have led electric mobility to a reality. Numerous materials capable of storing lithium reversibly, either as an anode or as a cathode, are reported on a daily basis. But very few among them, such as LiCoO2, lithium nickel manganese cobalt oxide (Li-NMC) variants (LiNi0.33Mn0.33Co0.33O2, LiNi0.5Mn0.3Co0.2O2, LiNi0.6Mn0.2Co0.2O2, and LiNi0.8Mn0.1Co0.1O2), LiNi0.8Co0.15Al0.05O2, LiFePO4, graphite, and Li4Ti5O12 are successful at commercial scale. Future energy requirements demand a push in the energy density of LIBs to meet the criteria of electric aviation, power trains, stationary grids, etc. All these applications have different needs which cannot be satisfied by a particular set of materials. Therefore, various materials need to be utilized in widespread fields of battery applications in the near future. This review discusses potential cathode materials that show a capacity of ≥ 250 mAh g-1 (Li-rich oxides, conversion materials, etc.) or average voltage of ≥ 4 V vs. Li+/Li (polyanionic materials, spinel oxides, etc.). Failure mechanisms, challenges, and way-outs to overcome all the issues are put forward to determine commercial viability.

Abstract A straightforward hydrothermal process followed by a controlled calcination technique is proposed for the synthesis of a Ni(OH)2 modified NiO nanohybrid structure. Conversion materials such as Li-ion battery anodes, NiO in this case, suffer from capacity fade and structural/morphological instability during lithiation and delithiation. The novelty of this work is in utilizing this hybrid configuration to increase the specific capacity and enable reversible electrochemistry. In the present work, we study the lithiation/delithiation process of NiO using a suite of spectroscopy and microscopy techniques from the atomic to electrode scale. We propose a mechanism for a reversible redox couple behavior of the NiO electrode by means of a hybrid Ni(OH)2/NiO structure. The ultimate objective of this work is to guide the development of anode with rationally designed heterogeneity to create high-capacity Li-ion batteries with excellent cycling and rate performance.

Electric Vehicles (EVs) are gaining momentum due to several factors, including the price reduction as well as the climate and environmental awareness. This paper reviews the advances of EVs regarding battery technology trends, charging methods, as well as new research challenges and open opportunities. More specifically, an analysis of the worldwide market situation of EVs and their future prospects is carried out. Given that one of the fundamental aspects in EVs is the battery, the paper presents a thorough review of the battery technologies—from the Lead-acid batteries to the Lithium-ion. Moreover, we review the different standards that are available for EVs charging process, as well as the power control and battery energy management proposals. Finally, we conclude our work by presenting our vision about what is expected in the near future within this field, as well as the research aspects that are still open for both industry and academic communities.
