Nanopore Battery
A nanopore battery is a rechargeable battery that is a composite of billions of nanoscale batteries formed within the pores of a substrate. The space inside the holes is so small that billions of pores combined equal the volume of a grain of sand. Each pore's diameter was some one eighty-thousandth the width of a human hair. Construction In 2014 a demonstration device was made from a ceramic sheet made of anodic aluminum. It held two vanadium pentoxide nanotube electrodes separated by an electrolyte that carried the electrical charge between the two. The current collector was made of ruthenium. The individual batteries are connected in parallel. The is prelithiated at one end to form the anode, with pure at the other end to form the cathode. The battery asymmetrically cycles between 0.2 V and 1.8 V. Performance The capacity retention of this full cell (relative to 1 C values) is 95% at 5 C and 46% at 150 C, with a 1,000-cycle life. A demonstration device was fully charged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rechargeable Battery
A rechargeable battery, storage battery, or secondary cell (formally a type of Accumulator (energy), energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulator (energy), accumulates and energy storage, stores energy through a reversible electrochemical Chemical reaction, reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from Button cell#Rechargeable variants, button cells to megawatt systems connected to grid energy storage, stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid battery, lead–acid, zinc–air battery, zinc–air, nickel–cadmium battery, nickel–cadmium (Ni ...
