Development of electric double layer capacitors, reduction of low ESR, and application expansion.

basic information

**Lecture Summary** Capacitors, which can rapidly charge and discharge, are collectively referred to as secondary power sources with high reliability, including electric double-layer capacitors (EDLC) and lithium-ion capacitors (LIC), both of which have been industrialized. EDLCs have advantages such as high output density, long lifespan, and high reliability compared to secondary batteries, but they have the disadvantage of low energy density. As a result, small-sized EDLCs have been widely used primarily for memory backup applications, but in recent years, the industrialization of larger models for backup and power applications has been progressing. LICs are a new type of capacitor that combines the best features of both EDLCs and lithium-ion batteries. While maintaining the excellent characteristics of EDLCs, they have improved energy density by 3 to 4 times compared to EDLCs, and they are expected to open up new applications that were difficult to implement with the energy density possessed by EDLCs. This presentation will discuss recent advancements in capacitor technology, as well as the markets where capacitors are currently in use and those where practical applications are anticipated.
