Electricity plays a leading role in industrial development, urbanization, and economic development, as well as in our daily lives. However, in the case of fluctuating power demand, there is often an imbalance between power generation and power consumption. In addition, to reduce carbon emissions, climate change, and energy supply shortages, along with the development of some renewable energy sources, power generation worldwide is undergoing major changes. Therefore, the instantaneous demand for electrical energy and the unpredictable daily and seasonal demand changes pose serious challenges to the power grid in the process of energy production, transmission, and distribution.
In practical use, for example, during electrical energy conversion. As an instant power supply system, grid-scale energy storage systems
have been used to support a wide range of applications from power generation to transmission and large electronic devices. For stationary applications, grid-level power storage systems store excess power during peak power generation and provide idle power during peak load periods to stabilize the power system through load balancing and peak shaving.
In addition, the energy storage system can balance the load and power of the grid through charging and discharging and provide a regulated power supply to the grid with a fast response time. Energy storage systems can also help create sustainable low-carbon electricity models that make efficient use of intermittent renewable energy. Furthermore, as a power monitoring network, the grid system can predict/diagnose faults to identify anomalies/weak points.
Among these energy storage systems, batteries show considerable application potential in grid-level energy storage due to their flexible installation, modularity, fast response, and short construction period. Generally speaking, when batteries are applied to grid-level energy storage systems, battery technology is required to meet complex and large-scale grid deployment applications. Therefore, requirements for grid energy storage applications such as capacity, energy efficiency (EE), lifetime, and power and energy density should be considered.
Among various battery technologies, lithium-ion batteries (LIBs) are used as supporting devices in the power grid due to their high energy density (up to 200 Wh/kg), high energy efficiency (above 95%), and long cycle life (at 3000 cycles at 80% deep discharge are of interest. To date, 77% of electricity storage systems used to stabilize the grid in the US rely on LIBs, indicating that LIBs is a high-value market.
Furthermore, given their high energy density, LIBs would be ideal for integration with renewable energy sources in grid-scale energy storage systems, where LIBs store the generated electrical energy so that it can be used at minimal cost when needed by the end consumer.
In recent years, LIBs have been successfully developed and their performance has improved significantly. More and more people are using it. If you want to know more information about lithium-ion energy storage systems or need to buy them, please contact us
