Sodium sulfur battery is one of the most promising candidates for energy storage applications. This paper describes the basic features of sodium sulfur battery and summarizes the recent development of sodium sulfur battery and its applications in stationary energy storage.
Sodium sulfur battery is one of the most promising candidates for energy storage applications developed since the 1980s . The battery is composed of sodium anode, sulfur cathode and beta-Al 2 O 3 ceramics as electrolyte and separator simultaneously.
Overall, the combination of high voltage and relatively low mass promotes both sodium and sulfur to be employed as electroactive compounds in electrochemical energy storage systems for obtaining high specific energy, especially at intermediate and high temperatures (100–350 °C).
Advanced battery constructions appeared since the 1980s. Previously, the research work on sodium sulfur battery was mainly focused on electric vehicle application, main institutions engaged in the research include Ford, GE, GE/CSPL, CGE, Yuasa, Dow, British Rail, BBC and the SICCAS.
The batteries produced have high cycle life, nearly 2500 cycles to fully depth of discharge . Sodium sulfur battery has been adopted in different applications, such as load leveling, emergency power supply and uninterrupted power supply .
Utility-scale sodium–sulfur batteries are manufactured by only one company, NGK Insulators Limited (Nagoya, Japan), which currently has an annual production capacity of 90 MW . The sodium sulfur battery is a high-temperature battery. It operates at 300°C and utilizes a solid electrolyte, making it unique among the common secondary cells.

BYD are able to make cells to a range of dimensions. The following set of specifications gives an example set of numbers that are consistent for this particular cell: . In the pack shown here the electrical connections run down both sides of the pack. The cells arranged alternately +ve and then -ve to connect. . The cooling plate is a single large plate that is fixed to the top surface of the cells. The coolant connections are both at the front of the plate. This. . BYD reports no fire or explosion from the following tests: 1. crushed 2. bent 3. heated in a furnace to 300°C 4. overcharged by 260%. [pdf]

To calculate the capacity of a lithium-ion battery pack, follow these steps:Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah).Identify the Parallel Configuration: Count the number of cells connected in parallel. For instance, if four cells are connected in parallel, the total capacity is the sum of the individual capacities. [pdf]

Currently, research and applications in the field of capacity prediction mainly focus on the use and recycling of batteries, encompassing topics such as SOH estimation, RUL prediction, and echelon use.
The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].
Firstly, feature extraction is performed from raw data, typically including voltage, current, and temperature. Subsequently, various machine learning methods are employed to establish the relationship between HIs and capacity, thereby realizing battery capacity estimation.
The manufacturing process of LIBs is divided into three stages: electrode production, battery assembly, and battery activation . In battery activation, the electrolyte is injected. Subsequently, formation and grading are conducted .
However, there is scant research and application based on capacity prediction in the battery manufacturing process. Measuring capacity in the grading process is an important step in battery production. The traditional capacity acquisition method consumes considerable time and energy.
