How are ESR and tan δ related?
Tan δ, or dissipation factor, is a property of a capacitor used to express energy loss within the capacitor. The higher the tan δ, the more energy is lost.
Tan δ is used to calculate ESR. The formula to calculate ESR is ESR = tan δ * Xc or tan δ / (2πFC)
Do aluminum electrolytic capacitor voltages change with temperature?
The rated voltage of an aluminum electrolytic capacitor does not change based on temperature. The capacitor’s rated voltage can be applied across its entire specified temperature range.
Does applied voltage change the capacitance of an aluminum electrolytic capacitor?
No. The capacitance of an aluminum electrolytic capacitor does not change with applied voltage.
How long can aluminum electrolytic capacitors be stored on the shelf?
Aluminum electrolytic capacitors can be stored without voltage being applied to them at 5 °C to 35 °C for up to two years after the date of manufacture. After two years the parts need to be checked to verify they have not drifted out of specification. If they have drifted out of specification, their shelf storage life can be extended by performing a voltage treatment.

What happens if an LTO battery becomes over-discharged?
Over-discharged state is when the voltage falls below the lower limit cutoff voltage limit, and if this state persists for a long time, degradation such as an increase in the battery's internal resistance will occur. It is recommended to prevent over-discharge from occurring, the battery should be periodically charged using proper battery management to prevent any other damage to the battery. Nichicon's LTO batteries can be safely recharged and used even after being over-discharged.
What should I do if an LTO battery has been stored for a long time and becomes over-discharged (voltage below the lower charging limit)?

Why can Nichicon's LTO batteries be used safely even after over-discharge?
When lithium-ion rechargeable batteries are left in an over-discharged state for a long period, degradation occurs inside the battery, such as the dissolution of the copper foil in the negative electrode, making safe charging impossible. On the other hand, Nichicon's LTO batteries do not use copper foil in the negative electrode, so they can be safely recharged and used even after being over-discharged.
Why do lithium-ion batteries degrade over time?
