A battery energy storage system is comprised of a battery module and a power conversion module. This paper starts by reviewing several potential battery systems, as well as an advanced aluminum-ion battery that currently has promising prospects in the electrochemical energy storage system. The characteristics of the batteries are reviewed and compared, including the materials, electrochemistry, performance and costs. The application prospect of the batteries is discussed. The paper summarizes the features of current and future grid energy storage battery, lists the advantages and disadvantages of different types of batteries, and points out that the performance and capacity of large-scale battery energy storage system depend on battery and power condition system (PCS). The power conversion system determines the operational condition of the entire energy storage system. The new generation wide bandgap semiconductor for power electronic technology is discussed from the perspective of performance, topology, model and non-linearity and is compared to the traditional silicon-based semiconductor.

BatteryEnergy storage systemPower condition systemWide bandgap semiconductorCarbon emissions have caused 4 °C (7.2 °F) of warming that could cause a sufficient eventual sea level rise to submerge land that is currently home to 470–760 million people globally. To cope with global climate changes and energy supply shortages and to achieve carbon emission reductions, developed countries must adjust development strategies in succession, formulate new low carbon-oriented patterns of economic development, and initiate strategic moves toward a low-carbon economy. As a high energy-consuming country, America mainly uses electricity (68.4%) generated from thermal power stations. According to the future energy plans announced by the U.S. Department of Energy, 20% of the electricity in America will be generated from wind power and 10% of the electricity will come from solar photovoltaic power by 2030.In Germany, the high number of installed intermittent renewable energy systems has had a significant influence on the operation of power systems and coal power plants. By 2034, the total installation capacity of wind power and solar photovoltaic power is expected to be approximately 173 GW, twice the current peak power in Germany. However, the instant power supply gap between the intermittent fluctuation of the intermittent renewable energy and the demand fluctuation of the load side was as high as 74.335 MW, which was equivalent to 92% of the peak loading in Germany. To guarantee the stability. Because the energy storage technique possesses an extremely high strategic position, all countries around the world continuously support the fundamental researches and application projects of the energy storage techniques. In 2013, Japan's New Energy and Industrial Technology Development Organization (NEDO) conducted the development of route planning aiming at all types of battery energy storage techniques, which paid special attention to the development of techniques, e.g., lithium-ion (Li-ion) batteries, sodium-sulfur batteries and advanced batteries. At the end of 2014, the United States Department of Energy (US DOE) released relevant technical reports on the development and application of all types of advanced batteries, and special attention will be paid to research directions such as super lead acid and advanced lead acid batteries, Li-ion batteries, sulfonic batteries, flow batteries, metal-air batteries and advanced compressed air energy storage technology.Batteries, which are an electrical energy storage technology that has high investment benefits at present, is characterized by modularization, rapid response and a high commercialization potential. With the technical innovation and successful development of the new batteries, the efficiency, power density, energy density and cycle life of batteries have improved remarkably. The battery system is associated with flexible installation and short construction cy. 3.1. Battery systemsFirst, the construction of the battery system should be based on specific application requirements, such as capacity, power, charge-discharge rates as well as response time, then a suitable battery systems should be chosen. Second, the construction form should be determined in accordance with both the power and capacity. A robust battery module is fundamental for constructing an efficient battery system. However, the existing electrochemical energy storage systems cannot comprehensively satisfy the requirements for grid energy storage application, especially with regard to cost,. Therefore, developing new or improving existing cost-effectiveness for electrochemical energy storage systems with good performance has generated increased interest from researchers. Here, the authors reviewed several promising battery systems with good application prospects in the energy storage field.3.2.
