All batteries work the same way, despite the various types appearing totally different to the eye.
Lithium-ion batteries are so common nowadays we sometimes wonder whether hardware stores sell batteries with free power tools.
Battery intercalation is a complex topic. However we dedicated this website to explaining battery basics. Thus we are going to keep this conversation at a high level.
When we browse for batteries on the internet and in shops, we hope to balance longer life against affordable cost. Portable consumer goods added a third dimension because the pressure is always to go smaller. Sometimes this puts unreasonable pressure on lithium battery technology, as witness the Samsung Galaxy 7 recall.
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.
All batteries have three basic bits that make our phones work, our cars start, and our alarm batteries function. In summary form, these components are a cathode, an anode, and some electrolyte. Disposing of batteries responsibly is still a challenge. Researchers at Toronto University may have a solution.
From a previous post, we learned about the electrolyte in a battery and how important it is in creating current which powers our machines/systems/applications. Now we are ready to test our battery to ensure its optimum performance. Testing A Battery (Something interesting…) There are many ways to test a battery but the most common and […]
Electric vehicles are the best way to combat rising air pollution and carbon emissions. However, their success depends on battery performance. Nanotechnology scientists continually search for the perfect battery to reduce the price, increase durability and offer more miles on every charge. One specific battery made of nickel, cobalt and aluminum (NCA) offers […]
The technology of li-ion batteries may be the best energy storage yet. Considered as today’s ultimate rechargeable battery, li-ion is lightweight, portable and can store a vast amount of energy which can be discharged and recharged for many cycles. Its affordability makes it a great source of power for consumer electronics. It is no wonder […]
Oxidation-reduction, or redox reactions, takes place in electrochemical cells. There are two different types of electrochemical cells. Spontaneous reactions occur in galvanic (voltaic) cells and non spontaneous reactions occur in electrolytic cells. Both types of cells contain electrodes where the oxidation and reduction reactions occur. Oxidation occurs at the electrode called the anode […]
