← ScienceWhich consequence results within a nickel-metal hydride (NiMH) battery during rapid discharge?
A)Reduced ionic conductivity within electrolyte✓
B)Increased oxide layer semiconductor passivation
C)Formation of cathode material dendrites
D)Decreased hydrogen gas recombination kinetics
💡 Explanation
Rapid discharge depletes electrolyte ions unevenly, hence ionic conductivity decreases due to concentration polarization. This limit reduces current output because of increased internal resistance, therefore conductivity lessens rather than options related to alternative failure.
