Abstract:

Na-ion batteries can meet the application requirements of being cost effective and having high safety in the field of energy storage due to the abundance of resources and their low cost, high energy conversion efficiency, long cycle life, low maintenance cost, and high level of safety. However, as a new chemical power system, Na-ion batteries have no related standard or specifications for their industrialization and marketing, which will seriously restrict the development of Na-ion battery technology. It is important to establish relevant national or industrial standards to standardize the inspection and quality of Na-ion batteries,regulate the market, and promote technological progress. In this article, we first introduce the situation concerning the global lithium and sodium resources. Then, we specify the characteristics and advantages, industrialization status, problems, and future development trends of Na-ion batteries, analyzing the current status of Na-ion battery standards worldwide and the reference standards or specifications of other batteries to point out the necessity of this exercise. Finally, we summarize the development history and reference significance of the standardization work done on lithium-ion batteries and suggest that the standard for Na-ion battery can be based on that of lithium-ion batteries, taking the characteristics of Na-ion batteries into account.

Key words: Na-ion batteries, standards, industrialization
