22 Due to the larger contact area between the electrolyte and electrode, it is necessary to improve energy density and increase surface-to-volume ratio, which is highly in demand. (7−10) However, despite having a well-developed technology, metal-ion (Li-ion) batteries are hampered with low energy density and therefore are unable to cope with the soaring demands for energy.

High performance, lightweight supercapacitor

In energy storage devices, storing an electrical charge is called energy density, a distinction from power density, which refers to how quickly energy is delivered. Conventional capacitors have high power density but low energy density, which means they can quickly charge and discharge and release a burst of electric power in a short time, but they can't hold a large amount of electric

Designing a hybrid electrode toward high energy density

2020/2/11The limited energy density, lifespan, and high cost of lithium-ion batteries (LIBs) drive the development of new-type affordable batteries. As a green and cheap alternative, dual-graphite batteries (DGBs) have received much attention recently; however, they have been criticized for low capacity, electrode durability, and "real" energy density. Here, we designed hybrid LiFePO4(LFP)/graphite
