Basics of High-Entropy Materials
High-entropy materials (HEMs) constitute a revolutionary class of materials that have garnered significant attention in the field of materials science, exhibiting extraordinary properties in the realm of energy storage. These equimolar multielemental compounds have demonstrated increased charge capacities, enhanced ionic conductivities, and a prolonged cycle life, attributed to their structural stability. In the anode, transitioning from the traditional graphite (372 mAh g−1) to an HEM anode can increase capacity and enhance cycling stability. For cathodes, lithium iron phosphate (LFP) and nickel manganese cobalt (NMC) can be replaced with new cathodes made from HEMs, leading to greater energy storage. HEMs play a significant role in electrolytes, where they can be utilized as solid electrolytes, such as in ceramics and polymers, or as new high-entropy liquid electrolytes, resulting in longer cycling life, higher ionic conductivities, and stability over wide temperature ranges. The incorporation of HEMs in metal–air batteries offers methods to mitigate the formation of unwanted byproducts, such as Zn(OH)4 and Li2CO3, when used with atmospheric air, resulting in improved cycling life and electrochemical stability.

Batavia (Ship)
Batavia (Dutch pronunciation: [baːˈtaːviaː] (listen)) was a ship of the Dutch East India Company (VOC). It was built in Amsterdam, Dutch Republic, in 1628, and armed with 24 cast-iron cannons and a number of bronze guns. Batavia was shipwrecked on her maiden voyage, and was made famous by the subsequent mutiny and massacre that took place among the survivors. A twentieth-century replica of the ship is also called the Batavia and can be visited in Lelystad, Netherlands.

Bâton de Commandement
A bâton de commandement, bâton percé or perforated baton is a name given by archaeologists to a particular prehistoric artifact that has been much debated. The name bâtons de commandement was the name first applied to the class of artifacts, but it makes an assumption of function; the name bâton percé, meaning "pierced rod", or "perforated baton" (the term used by the British Museum) is a more recent term, and is descriptive of form rather than any presumed function. Many are decorated with carved or engraved animals, and the most usual explanation of their use is that they were used for straightening spears and arrows, and as spear-throwers.

Batteries for Internet of Things Applications
There has been significant progress in IoT solutions for a variety of fields. The real-time functionality and remote deployment of IoT solutions are two crucial aspects that are necessary for their successful implementation. To achieve this, external batteries play a major role. While lithium–ion batteries are often the go-to choice for IoT devices, it is essential to recognise that different IoT applications have unique needs. Therefore, it is important to conduct a thorough examination of existing battery solutions and their suitability for various IoT applications.

Battery Charging Techniques for Unmanned Aerial Vehicles
Unmanned Aerial Vehicles (UAVs) are intended to be controlled remotely, either through predefined trajectories or through a radio controller. UAVs are now essential components in both civilian and military applications. UAVs, on the other hand, are energy-hungry devices that deplete batteries within minutes of operation. Due to limited battery capacity, UAVs have short flight times.

Battery Electric Vehicles and Hydrogen Fuel Cell Vehicles
During the last few years, electric and hydrogen vehicles have become an alternative to cars that use internal combustion engines. The number of electric and hydrogen vehicles sold has increased due to support from local governments and because car manufacturers will stop the production of internal combustion engines in the near future. The emissions of these vehicles while being driven are zero, but they still have an impact on the environment due to their fuel.

Battery Energy Storage Systems
The battery energy storage system can be applied to store the energy produced by renewable energy sources (RESs) and then utilized regularly and within limits as necessary to lessen the impact of the intermittent nature of renewable energy sources.

Battery Energy Storage Systems Ancillary Services
The battery energy storage system (BESS) is significant in providing ancillary services to the grid. The BESS plays a crucial role in facilitating the integration of renewable energy sources (RESs) into the grid by compensating for the fluctuations produced by RESs as intermittent resources. Ancillary services encompass all the services necessary for the grid operator (transmission and distribution operator) to maintain the system’s integrity, stability, and power quality. Grid operators ensure a reliable power supply, frequency, voltage, and power load within certain limits.
