Lithium ion battery energy storage technology is still irreplaceable

They discussed an energy storage technology that could be considered a reliable alternative to lithium-ion energy storage, and their conclusion was clear: there is no sign of the end of the "post lithium" era.
The team concluded that the current climate of future technology needs after the lithium age and the pursuit that new technologies can replace lithium battery technologies are inappropriate and misleading. "
Instead, they recommend a "parallel" approach to all energy storage technologies. They also identified technologies that they think are more promising for the future.
Na ion batteries, which rely on the same ionic energy storage principles of lithium-ion technology, are considered to be an interesting alternative because they can provide an affordable solution due to the potential shortage of lithium and cobalt, or the possible price surge. They are also easy to transport and have great potential to further reduce the cost of raw materials. "In fact, the cost and environmental friendliness of the layered oxide cathode materials proposed so far seem to be the main advantages of Na ion batteries," the team said.
The report added that Na ion batteries face similar safety problems as lithium-ion batteries in large-scale applications, but their development is still limited, and there is insufficient understanding of the failure modes, mechanisms and analysis at the whole battery level. It is recommended for fixed energy storage systems and light vehicles for short haul transportation.
"Redox mobile batteries are expected to surpass lithium-ion batteries only in static applications, because their key feature is that they store energy in external reservoirs, which can store energy from renewable resources during peak production periods and supply them when production declines," the team explained. At the same time, the development of advanced materials and chemistry is considered necessary to overcome the limitations of existing concepts and improve system performance. "
According to the analysis of the micro lithium battery team, lithium ion battery technology will still be of great importance in many years to come in metal air batteries and energy storage devices based on multivalent metal anodes.
