Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and the non-aqueous electrolyte. Almost all mobile phones we use are lithium batteries. At present, most of the popular electric vehicles on the market are powered by lithium iron phosphate batteries. How do the lithium batteries charge and…
Lithium-ion batteries are constructed from two positive and negative electrodes separated by a liquid chemical electrolyte, such as ethylene carbonate or diethyl carbonate. The chemical composition of this battery limits it to a mostly rectangular shape. Lithium-ion battery capacity decreases over charge cycles and even discharges when not in use, which isn’t ideal. The 18650 size is…
I loaned a family member a dewalt 20v sawzall, they returned it with a completely discharged battery!!! There is hope, the battery should have internal cutoff at determined low voltage NO NO No it’s not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact…
What relief, government gets the chance to screw the public and they actually make the right decision and let it Pass. Must have to do with the makeup of the legislature. We love Volusia County and New Smyrna Beach. Of course it won’t be long before the Orlando-south Fl garbage makes their way here. Enjoy…
What does Google know about me? Gabriel Weinberg, CEO & Founder, DuckDuckGo (2008-present)Updated January 11 · You may know that Google is tracking you, but most people don’t realize the extent of it. Luckily, there are simple steps you can take to dramatically reduce Google’s tracking. But first, what exactly are they tracking? Unlike searching on DuckDuckGo, when you…
First–The terms “LED driver” and “LED power supply” are used interchangeably. Conventional AC-DC power supplies and DC-DC converters provide an output that is regulated to provide a “constant-voltage.” However, LEDs work most efficiently and safest with a “constant-current” . As a result, many new devices have been developed to provide this type of LED drive….
The Internet of things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. Things have evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and…
