The Eaton PHVL-3R9H474-R supercapacitor (Figure 3, left), is a 470 millifarad (mF), 3.9 volt device with dual cells. It has a very low effective series resistance (ESR) of 0.4 ohms (Ω) to reduce conductive losses, and it can deliver a peak power of 9.5 W. It has an operating temperature range of -40°C to +65°C.

As for LCD and plasma displays, LCDs, as mentioned, have a HV inverter generating 1-3 kV if they have a CCFL backlight, but no charge is present when powered off, aside from maybe some residual voltage on the small (10-30 pF) capacitors used to couple the output to the CCFLs (the output is AC though), which store too little energy to really

Tantalum, MLCC, and super capacitor technologies are ideal for many energy storage applications because of their high capacitance capability. These capacitors have

Summary: Capacitors for Power Grid Storage. ($/kWh/cycle) or ($/kWh/year) are the important metrics (not energy density) Lowest cost achieved when "Storage System Life" = "Application Need". Optimum grid storage will generally not have the highest energy density. Storage that relies on physical processes offers notable advantages.

Benefiting from the synergistic effects, we achieved a high energy density of 20.8 joules per cubic centimeter with an ultrahigh efficiency of 97.5% in the MLCCs. This approach should be universally applicable to designing high-performance dielectrics for energy storage and other related functionalities.

Table S8.1 (Supporting Information) shows that the ceramic capacitors have a high surface energy-storage density (per unit surface-area of the capacitor, U a [J cm −2]), which allows for the selection of smaller surface-area capacitors for energy storage applications.
