“…Among the available polyanion-type composites is the composite phosphor olivine-structured LiXPO 4 (LXPO, where X is a transition metal type) cathode material with a theoretical specific discharging capacity (∼170 mAh g –1 ). − Among these materials, LiFePO 4 (LFPO) has distinctive semantics that support its application as a cathode in the manufacturing of rechargeable LIBs. − LFPO–cathode electrodes have also been effectively used in manufacturing rechargeable LIBs because of their stable crystal structures and surface topologies, high safety, low cost, and environment-friendly qualities. − However, LFPO-based cathode materials have obvious disadvantages that limit their use in electrode-designed LIB applications, including their poor reversibility and capability rates, weak conductivity and electron diffusivity, and slow electron/Li + ion transport along LFPO-solid/electrolyte interfaces. − Therefore, several strategies for designing hierarchical cathode electrodes have been developed to overcome the aforementioned limitations and to enhance the conductivity and facilitate the durable transport of Li + ions. , Several strategies for fabricating multifunctional cathode electrode-based nanomaterials and its hierarchical structures have also been applied for energy storage/conversion designs. These strategies were used for modification surface of electrodes such as (i) modifying their nano/micro-structured surfaces and (ii) decorating these materials with supervalent metal composites, highly conductive materials, highly exposed facet surfaces, and hierarchically structured configurations. − The synthesis of potential LFPO–cathode electrode composites with high surface heterogeneity and highly conductive carbon layers was controlled by using woven decoration methods or the surface-doped strategy. ,,, The development of hierarchical LFPO–cathode models with 3D multifunctional complex architectonics and a mixture of heterogeneous surface composites can facilitate the fabrication of LIB pattern assemblies with diverse geometric scales.…”

We fabricate diverse geometric scales of lithium-ion battery (LIB) pattern assemblies in CR2032-circular coin designs by using complex building-block (CBB) anode/cathode electrodes as hierarchical models. The CBB anode/cathode electrode architectonics are designed with multiple complex hierarchies, including uni-, bi-, and tri-modal morphologies, multi-directional configurations, geometrical assemblies oriented in nano-/micro-scale structures, and surface mesh topologies, which allow us to leverage half-and full-cell CBB-LIB models. The CBB-LIB CR2032-circular coin designs have a Coulombic efficacy of ~99.7% even after 2000 th lithiation/delithiation (discharge/charge) cycles, an outstanding battery energy density of 154.4Wh/kg, and a specific discharge capacity of 163.6 mAh/g from 0.8 V to 3.5 V and at 0.1 C. The architectonic configurations and geometrics of the modulated full-cell CBB-LIB CR2032-circular designs play key roles in creating sustainable, full-scale CBB-mutated-LIBs with continuous and non-resisted surface transports and in achieving a sensible distribution of electron/Li + ions. With hierarchical uni-, bi-, and tri-modal complexities, a dense collar packing f anode/cathode CBBmutated-LIB pouch-type sets in stacked layers can facilitate a rational design of CBB-pouch-type LIBs. Our CBB-mutated pouch-type LIB models have a sustainable Li + ion-transport along multicomplex CBB-surfaces, substantial areal discharging capacity, and excellent volumetric-and gravimetric-cell energy densities and specific capacitances that fulfill the powerful force-driving range and tradeoff requirements in electric vehicle applications.

Road transport is showing growth in the period of globalization. Its task is to transport cargo as well as people to the required location within the shortest possible time and at the lowest price. Thus, road transport plays a crucial role in enabling the globalization to be developed and improved. However, the internal combustion engine hat prevail among the vehicles of freight and passenger transport are the producers of gaseous emissions from the exhaust gases. Many developed countries of the world has committed themselves, inter alia also trough the Paris Agreement, to reduce global warming, and thus to reduce the production of harmful gaseous emissions. The result is the endeavour to replace the internal combustion engine vehicles that burn carbon fuels with the vehicles powered by electric motors consuming electric energy. The reason of such trying claims that road transport using the internal combustion engine vehicles is environmentally aggressive, and the problem would not be solved by implementation of the vehicles with electric motors. Such claim is based on the fact that an electric car does not produce any of primary emissions. From an overall perspective, it is also necessary to take into account secondary emissions that are produced during the electric energy production by which is the vehicle with electric motor powered. The purpose of this article is to assume the possibility of reducing global pollution by replacing the internal combustion engine vehicles with the vehicles powered by electric motors in dependence with producing the emissions during the production of electric energy.

“…Cold-temperature operation is one of the requirements. Most of the abovementioned batteries are ineffective in cold climates and high altitudes because of the severe power losses that occur when temperatures fall below zero degrees Celsius. − To overcome these challenges, in addition to moderating the defects of the battery itself, researchers are also working to explore new electrochemical energy storage systems. − …”

Transition metal borides Co–B and Co–Ni–B are prepared by a simple chemical reduction method and used to construct a new all-boride aqueous solution battery with borides used for both the anode and cathode. This all-boride-based battery exhibits an excellent electrochemical property and extreme frost tolerance. The results of the electrochemical performance test demonstrate that the specific capacity of this all-boride battery reaches 332.4 mA h g–1 at a current density of 500 mA g–1 and is maintained at 280 mAh g–1 with a high discharge current density of 8 A g–1 as a result of the rapid electrochemical reaction kinetics and high electronic conductivity. This all-boride battery can continue to work at low temperatures (−40 °C) and exhibits good electrochemical performance; therefore, it can be used under extreme cold weather conditions. The electrode material of the all-boride battery is simple to prepare, is energy-saving, does not require special equipment or a special environment during assembly, and thus shows promise as a new energy storage device.
