Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion.
A potassium-ion battery or K-ion battery (abbreviated as KIB) is a type of battery and analogue to lithium-ion batteries, using potassium ions for charge transfer instead of lithium ions. It was invented by the Iranian/American chemist Ali Eftekhari (President of the American Nano Society) in 2004.
Sodium-ion and potassium-ion batteries are two forerunners in the disruptive battery technologies race that could be set to rival lithium batteries. Two key elements in lithium batteries – lithium and cobalt are considered to be relatively expensive due to their associated mining costs.
By contrast sodium-ion and potassium ion batteries are made from elements that are plentiful and cheap and can be sourced almost anywhere. They are proving their viability in a growing number of world-wide demonstrations as a safe and sustainable alternative to lithium batteries.
Emerging sodium-ion and potassium-ion batteries are feasible solutions for future large scale energy storage. Identifying and optimising the electrode materials for these new batteries is the key task,” said Alexey. Our research seeks to discover and improve negative and positive electrode materials for sodium-ion and potassium-ion batteries.
Because sodium and potassium are far more prevalent than lithium in the Earth's crust, rechargeable batteries based on sodium and potassium are feasible alternatives to lithium-ion batteries (LIBs). Over the last decade, rechargeable potassium-ion batteries (PIBs) have grown in popularity. However, PIBs development is still in its early stages.
