New sodium battery that can be charged in seconds developed
Researchers have developed a high-power hybrid sodium-ion battery that can be charged in seconds, potentially replacing lithium-ion batteries.
The combination helped the battery to achieve high storage capacities and rapid charge-discharge rates. “The development of a hybrid battery with high energy and high power density requires an improvement to the slow energy storage rate of battery-type anodes as well as the enhancement of the relatively low capacity of supercapacitor-type cathode materials,” said the team in a statement. The battery may fulfill an increasing demand for low-cost electrochemical energy storage devices with high energy density for prolonged operation on a single charge and fast-chargeable power density to meet a wide range of applications ranging from mobile electronic devices through electric vehicles (EVs) to large-scale grid systems.
