Lithium-ion battery is a very important energy storage technology, which is widely used in portable electronic devices and new energy vehicles. With the advent of the era of electric vehicles and smart grids, the large-scale development of lithium-ion batteries is limited by the bottleneck of lithium resource shortage. Compared with lithium, sodium reserves are abundant, widely distributed, low cost, and have similar physical and chemical properties to lithium, so the research of sodium ion batteries has once again received extensive attention from the scientific and industrial circles. Compared with lithium ion batteries, sodium The energy density of ion batteries is usually low. Although it is not suitable for applications in the field of portable electronic equipment and electric vehicles with high energy density requirements, it is suitable for low-speed electric vehicles that are not too energy-intensive and cost-sensitive. And communication base stations, home energy storage and other fields. The following options match the meaning of this text:. ['In terms of economic benefits, sodium ion batteries are more affordable than lithium ion batteries.', 'The expensive construction cost of lithium-ion batteries is the bottleneck of its development.', 'Sodium ion batteries have a wider range of applications than lithium ion batteries.', 'Lithium-ion batteries will not be completely replaced by sodium-ion batteries.']
