The useful life of electrochemical energy storage (EES) is a critical factor to system planning, operation, and economic assessment. Today, systems commonly assume a physical end-of-life criterion: EES systems are retired when their remaining capacity reaches a threshold below which the EES is of little use because of insufficient capacity and efficiency.

High efficiency and low cost power converters for interfacing energy storage have become critical in renewable energy systems.

Electrochemical energy storage (EES) technology, as a new and clean energy technology that enhances the capacity of power systems to absorb electricity, has become a key area of focus for various countries. Under the impetus of policies, it is gradually being installed and used on a large scale.
After the end of the service life of the energy storage power station, the assets of the power station need to be disposed of, and the end-of-life costs mainly include asset evaluation fees, clean-up fees, dismantling and transportation fees, and recycling and regeneration treatment fees.
Energy storage is the process of storing energy through media or equipment and releasing it when needed (Hua, 2019). Energy storage enables the temporal and spatial transfer of electric energy, which can effectively isolate the production and utilization of electric power.
The learning rate of China's electrochemical energy storage is 13 % (±2 %). The cost of China's electrochemical energy storage will be reduced rapidly. Annual installed capacity will reach a stable level of around 210GWh in 2035. The LCOS will be reached the most economical price point in 2027 optimistically.
In order to evaluate the cost of energy storage technologies, it is necessary to establish a cost analysis model suitable for various energy storage technologies. The LCOS model is a tool for comparing the unit costs of different energy storage technologies.
By calculating a single score out of CF and cost, a final recommendation is reached, combining the aspects of environmental impacts and costs. Most of the assessed LIBs show good performance in all considered application cases, and LIBs can therefore be considered a promising technology for stationary electrochemical energy storage.
