2. Normative references The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies. IEEE Std 1679™-2010, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications. 2,3 3. Defnitions, acronyms, and abbreviations 3.1 Defnitions For the purposes of this document, the following terms and defnitions apply. The IEEE Standards Dictionary Online 4 and IEEE 1881 Standard Glossary of Stationary Battery Terminology[B7] 5 should be consulted for terms not defned in this clause. molten-salt battery: a class of batteries that use molten salts as an electrolyte. See also: Sodium-Beta cell Sodium-Beta cell: a cell containing molten or semi-molten sodium and another material, which act as the negative and positive electrodes respectively. Sodium β″-alumina: An impermeable white ceramic, consisting of β″-alumina (β″-Al2O3) complexed with sodium ions, used in Sodium-Beta batteries as a separator and electrolyte. sodium-nickel chloride: A Sodium-Beta cell using nickel chloride as the main material in the positive electrode. NOTE—Most designs also include iron chloride in the positive so they are technically sodium-nickel-iron chloride cells 6 sodium-metal chloride: A generic name for a family of sodium-based cells using one or more chlorinated metal compounds as the positive electrode material. sodium-metal halide cell: See: sodium-metal chloride. sodium-sulfur cell: A Sodium-Beta cell using sulfur as the positive electrode material.
4. Document structure Clause 5 through Clause 9 of this document follow the clauses of IEEE Std 1679-2010. Information specifc to sodium batteries is included where appropriate. Additional subclauses have been added to this document where further guidance is required. 5. Technology descriptions 5.1 General Refer to Clause 5 of IEEE Std 1679-2010. This clause describes the main sodium batteries that are either used or are being considered for stationary battery applications. These include sodium-metal halide and sodium- sulfur. The information provided in this clause relates primarily to the energy storage system components of these technologies and does not address power conversion and grid interconnections.
