Button batteries, sometimes known as penny ones, are among the smartest, cleverest devices in the battery world.
Alessandro Volta made the world’s first battery in 1791. We don’t know why he piled alternating copper and zinc disks atop each other.
Electrodes are a special class of electrical conductors. Because they are able to contact a non-metallic part of a circuit, and so complete it.
The race is on to discover better batteries for electronic devices. Batteries that will charge faster, discharge slower
It sometimes seems as if our colleagues in the lithium industry emptied out their bathroom cabinets. Then they broke the contents into their constituents to see if they could build batteries
Garnet gemstones are a group of silicate minerals with a famous pedigree. First, their ruby glow attracted jewelers. Then woodworkers began applying a final finish to bare wood with garnet paper
Film capacitors are functionally similar to ceramic capacitors because they are both non-polarized. We can connect them either way around in a direct current environment.
Well not quite, although some home brewers might find the idea of a battery made from beer appealing. ACS Publications reports researchers at University of Colorado Boulder have found a way to convert wastewater from the brewing process into green electrodes.
The Parthian Empire controlled the Middle East and Central Europe from 247 BC to 224 AD. They were sophisticated people ahead of their time in terms of military technology and sculpture, and may have made an ancient battery.
If you think of an ‘elect-rode’ as being an electric rod, you are close to the truth. Another clue comes from the origin of the name. ‘Rhode’ means ‘a pathway’ in Greek. Hence electrodes are conductors through which electricity enters or leaves a substance or an object.
