Can Lithium Batteries Really Last 2 Years Before Losing Capacity?

AI Thread Summary
Lithium batteries experience capacity loss over time due to several factors related to their microstructure. After approximately 100 recharge cycles, the battery's performance diminishes primarily because of the degradation of porosity in the materials, which reduces the active area available for reactions. This aging process is influenced by phenomena such as sintering and corrosion of the negative electrode. Although lithium batteries operate on reversible reactions during charging and discharging, the physical and chemical changes in the materials lead to a decline in efficiency and capacity over a typical two-year lifespan.

I want to ask you something. What happens with the lithium battery (lets say after 100 times of recharging) and loses its capacity after 2 years recharging? Is it something with the ions or what?

Theoretically, it is a kind of reversible reactions : charged and discharged. But batteries do aging. It is because of the microstructure of the materials : The porosity is degrading, so reacting area or active area deduces over time, sintering etc..

You say that negative electrode corrode, right?
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
