Most battery-powered devices, from smartphones and tablets to electric vehicles and energy storage systems, rely on lithium-ion battery technology. Because lithium-ion batteries can store a significant amount of energy in such a small package, charge quickly, and last long, they have become the battery of choice for new devices. How Do Lithium-Ion Batteries Work? Lithium is stored in the battery’s anode, the positively charged electrode, and the cathode, which is the negatively charged electrode. A liquid electrolyte, or separator, transports positively charged lithium ions between the anode and cathode, the movement of which helps create free electrons in the anode. As a…

Voice over Internet Protocol (VoIP) is a technology that allows users to make phone calls using the Internet instead of a traditional phone line. VoIP is also known as IP telephony. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the delivery of…
