Capacitors and solid-state batteries

What is solid state capacitance?

The solid-state capacitance is made of polymer dielectric: at high temperatures, the particle growth and behavior of solid particles are lower than that of liquid electrolytes, and its boiling point will reach 350 degrees Celsius, making it almost impossible to burst.

Do solid-state capacitors work at high temperatures?

Solid-state capacitors can work at high temperatures and maintain various electrical properties. The capacitance changes less than 15% in the whole temperature range, which is obviously superior to the liquid electrolytic capacitance.

What is the surface capacity of a solid state battery?

An outstanding surface capacity was obtained (2.2 mAh cm 2) accompanied with a cut off potential equal to 2.45 V . Another key consideration in the construction of a solid state battery is the architecture of the electrodes. One of the promising trials was made by Soo and his group.

Which capacitor is used in CPU power supply?

At present, solid capacitors are mostly used in the CPU power supply of computer motherboard, but the capacity redundancy is very little, it is necessary to improve the switching frequency of the part of the CPU power supply. Both solid and electrolytic capacitors will have the problem of capacity attenuation in the process of use.

How long does a solid state capacitor last?

Whether solid or electrolytic capacitors, their main function is to filter clutter, so long as the capacity and quality of capacitance can reach certain requirements, it can also ensure a stable operation. Solid-state capacitors at 105C have the same lifetime as electrolytic capacitors for 2000 hours.

What is a solid-state aluminum electrolytic capacitor?

The solid-state capacitor is called a solid-state aluminum electrolytic capacitor. The biggest difference between it and ordinary capacitors (i.e. liquid aluminum electrolytic capacitors) lies in the use of different dielectric materials.
