After technological innovation in the seventies of the last century, miniaturization, portable electronic devices were possible, and since then, battery life has become a new challenge
.
Chemical batteries can store a lot of energy, but their charging and discharging process is relatively long and the battery life is limited
.
Capacitors enable fast charging, but their storage capacity is limited because they cannot be used in practical applications
.
Therefore, a solid-state micro supercapacitor came into being
.
Supercapacitors have the power of the battery and are able to maintain power for a long time
.
In the past, researchers have tried to use metal and polymer hybrid materials to prepare solid-state miniature supercapacitors, but their endurance cannot meet practical needs
.
Recently, solid-state micro-supercapacitors made of graphene and carbon nanotubes have also been lackluster
.
The international research team has developed a new technology, and the solid-state micro supercapacitor prepared by this technology solves the previous problem well and has good results
.
The team's test results were amazing
.
In addition to its ultra-high energy density, the film is very flexible and has a higher
capacitance after first use.
Its energy density is 10 times
that of current commercial supercapacitors.
The electronic characteristics of the solid-state miniature supercapacitor are almost 5 levels higher than that of current similar lithium batteries, which is comparable to current supercapacitors
.
In the future, consumers will prefer to use solid-state miniature supercapacitors rather than batteries
.
It has a longer lifespan and faster electron transfer speed in terms of light and energy storage
.
The solid-state micro supercapacitors developed by the team have a wide range of application fields, including medical devices, microrobots, and more
.
If engineers take advantage of the portability of the material, this solid-state miniature supercapacitor could even be used in wearable devices
