Commercial applications of lithium battery energy storage

Lithium-sulfur (Li-S) batteries hold great promise as energy storage systems because of their low cost and high theoretical energy density. Here, we evaluate Li-S batteries at a system level for the current most critical and challenging applications. Battery technologies play key roles in transforming societal development in a more sustainable way.

Here, we evaluate Li-S batteries at a system level with regard to the current most critical and challenging energy storage applications, i.e., automotive and stationary energy storage batteries (AESBs and SESBs, respectively) ( Figure 1 ). Figure 1. The Potential Implementation of Li-S Batteries in AESB and SESB Applications

Among various battery technologies, lithium-ion batteries (LIBs) have attracted significant interest as supporting devices in the grid because of their remarkable advantages, namely relatively high energy density (up to 200 Wh/kg), high EE (more than 95%), and long cycle life (3000 cycles at deep discharge of 80%) [11, 12, 13].

Lithium-based systems open a new era for high-energy and high-power batteries, and more and more often replace other battery technologies, such as lead-acid and nickel-based systems . Lithium-ion batteries are already in heavy use. However, most lithium-metal batteries are still in the experimental stage. 2.1.

Among several battery technologies, lithium-ion batteries (LIBs) exhibit high energy efficiency, long cycle life, and relatively high energy density. In this perspective, the properties of LIBs, including their operation mechanism, battery design and construction, and advantages and disadvantages, have been analyzed in detail.

In the electrical energy transformation process, the grid-level energy storage system plays an essential role in balancing power generation and utilization. Batteries have considerable potential for application to grid-level energy storage systems because of their rapid response, modularization, and flexible installation.
