What is the driving force to increasing the internal resistance of a battery

AI Thread Summary
The internal resistance of a battery increases over time due to several factors, including chemical degradation and depletion of active materials that maintain the potential difference. As a battery discharges, reactions occur that can lead to the formation of byproducts and changes in the electrode materials, contributing to higher resistance. Additionally, physical changes such as electrode corrosion and electrolyte depletion also play a significant role. These processes ultimately lead to reduced efficiency and capacity, causing the battery to "die." Understanding these mechanisms is crucial for improving battery longevity and performance.

What is the "driving force" to increasing the internal resistance of a battery

Homework Statement




A brand new battery almost have no resistance, but overtime when the internal resistance is great enough, the battery "dies". So my question is, what is causing the internal resistance to increase? Why can't resistance be the same forever?


The Attempt at a Solution



Don't throw me the second law of thermodynamics...
 
Physics news on Phys.org


the chemicals that maintain the potential difference run out.
 


Your direct and brief answer just made me feel so stupid lol
 


nothing to feel stupid...haha!
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
