Full Description
Scope
This document provides guidance for an objective evaluation of sodium-based energy storage technologies by a potential user for any stationary application. This document is to be used in conjunction with IEEE Std 1679-2010, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications.For the purposes of this document, sodium-based batteries include those secondary (rechargeable) electrochemistries with sodium as the active species exchanged between the electrodes during charging and discharging, and operating at or above the melting point of sodium. Examples of secondary sodium-based batteries are sodium-nickel chloride and sodium-sulfur batteries. This document does not apply to aqueous sodium-based battery technologies.The outline of IEEE Std 1679-2010 is followed in this document, with tutorial information specific to sodium-based batteries provided as appropriate. Examples of tutorial information include technology descriptions, operating parameters, failure modes, safety information, battery architecture, qualification and application considerations.This document does not cover sizing, installation, maintenance and testing techniques, except insofar as they may influence the evaluation of a sodium-based battery for its intended application.Purpose
Sodium-based batteries have been used in various, non-stationary applications for many years. They are now beginning to be used in stationary applications, and as such there is a need to provide appropriate information on safety and operating conditions related to these applications. Used with IEEE Std 1679-2010, this guide describes a format for the characterization of sodium-based battery technologies in terms of performance, service life and safety attributes. This format provides a framework for developers and manufacturers to describe their products. The resulting information assists users, integrators and servicing organizations in evaluating the possible use of these batteries in stationary applications and provides objective criteria for comparative evaluation.Abstract
New IEEE Standard - Superseded.This document provides guidance for evaluation of the characteristics and performance of sodium-beta batteries by a potential user for stationary applications. Information regarding technology description, safety, aging and failure modes, evaluation techniques, and regulatory issues is included in this guide. This document is to be used in conjunction with IEEE Std 1679, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications. Sodium-beta batteries include those secondary (rechargeable) electro-chemistries with sodium as the active 8 species exchanged between the electrodes during charging and discharging, and operating above the melting point of sodium. These batteries use a solid beta-alumina electrolyte, typically written as '-alumina. Examples of secondary sodium-beta batteries are sodium-metal chloride and sodium-sulfur batteries.
