Lithium-sulfur cells offer significant safety benefits over other battery types due to their operating mechanism. The 'conversion reaction', which forms new materials during charge and discharge, eliminates the need to host Li-ions in materials, and reduces the risk of catastrophic failure of batteries.
In this review, we describe the development trends of lithium-sulfur batteries (LiSBs) that use sulfur, which is an abundant non-metal and therefore suitable as an inexpensive cathode active material. The features of LiSBs are high weight energy density and low cost.
To realize a low-carbon economy and sustainable energy supply, the development of energy storage devices has aroused intensive attention. Lithium-sulfur (Li-S) batteries are regarded as one of the most promising next-generation battery devices because of their remarkable theoretical energy density, cost-effectiveness, and environmental benignity.
Disadvantages of lithium-sulfur battery The conductivity of sulfur in lithium-sulfur (Li–S) batteries is relatively low, which can pose a challenge for their performance. Thus, the low conductivity of sulfur (5.0 × 10 −30 S/cm ) always requires conductive additives in the cathode.
Another challenge is the volume expansion of sulfur during charge/discharge cycles, which can lead to electrode degradation and reduced life. In addition, the problems related to the low electrical conductivity of sulfur and the shuttle effect of polysulfides must be solved for the commercial viability of Li/S batteries.

In the traditional fixed threshold method, when the equalization turn-on threshold is larger, the equilibrium speed of the battery pack will be improved to a certain extent, but the advantages of the equalization strategy designed in this article in improving the inconsistency of the battery pack will be more obvious.
The goal of equalization is to increase the battery pack's consistency as well as the battery pack's real capacity. The higher the equalization efficiency, the shorter the battery equalization time. The balancing goal can be formulated as: where represents the SOC of the ith battery, the battery pack has 2 n batteries in total, .
To better quantify the equalization effect, the battery difference and energy utilization rate are defined for evaluation.
