How a lithium-ion battery charges and discharges Animation: Charging and discharging a lithium-ion battery. As their name suggests, lithium-ion batteries are all about the movement of lithium ions: the ions move one way when the battery charges (when it's absorbing power); they move the ...
Preface This is a very long (10,000 word, 60 image) blog post transcribing a lecture by professor Jeff Dahn from Dalhousie University titled "Why do lithium-ion batteries die, and can they be immortal?" Not only is Jeff at the top of his field (he seriou
Do LED lights get hot? How do LED lights produce heat? Can LED lights be left on 24/7? Can LED lights catch fire? How do LED lights work? Scientifically speaking, a LED bulb produces light when an electrical current goes through the diode, and then that same diode emits photons. This...
Many button-cell batteries (widely used in things likequartz watchesand hearing aids) work the same way as ordinary alkalines, with similar electrode materials and alkaline electrolytes; others use lithium and organic electrolytes and work through different chemical reactions. Look closely at a button ...
While current EVs mostly use lithium-ion batteries, there are many different variations of lithium-ion chemistries and this will influence how it responds to stress. In addition to cell chemistry, temperature control techniques differ across vehicle models. A major distinction is whether the battery ...
Geotab research shows that EV batteries could last 20 years or more at observed degradation rates. Read on to learn best practices to maintain EV battery health
So you quickly get some food, and eat half of it. What happens to the rest of the food on your plate? It may greatly go right into the waste. Is it common in your school? The answer is yes. Waste happens everywhere in the school. Some students often forget to turn off the lights...

Unfortunately, lithium-ion chemistry isn’t perfect—all batteries are consumables, which means they get old. And like us, when batteries get old, the processes that keep them running start to degrade. But where we get wrinkles and breathe out CO2, batteries produce toxic gases and bloat thems...
