Lithium battery energy storage

　　The lithium battery energy storage system stores and releases electrical energy by moving lithium ions between the positive and negative electrodes. During charging, lithium ions migrate from the positive electrode to the negative electrode through the electrolyte; During discharge, lithium ions migrate from the negative electrode to the positive electrode, generating an electric current.

　　Application scenarios

　　Peak shaving and frequency regulation of power grid: During peak electricity consumption periods, lithium battery energy storage systems can quickly release electrical energy to meet the needs of the power grid; During low periods, excess electricity can be stored.

　　Renewable energy grid connection: in conjunction with wind and photovoltaic power generation, smooth output power and reduce impact on the power grid.

　　Backup power supply: In places such as data centers and hospitals that require uninterrupted power supply, lithium battery energy storage systems provide reliable backup power.

　　Electric vehicles: The power source of electric vehicles, characterized by high energy density and long lifespan.

　　advantage

　　High energy density: Lithium batteries have a much higher energy density than other types of batteries and are suitable for storing large amounts of electrical energy in limited spaces.

　　Long lifespan: With proper maintenance, lithium batteries can undergo thousands of charge and discharge cycles.

　　Fast charging and discharging: Lithium batteries support high current charging and discharging, and can quickly respond to the needs of the power grid.

　　Environmental Protection: Free from harmful heavy metals, with minimal impact on the environment.

　　Challenge

　　Safety: Lithium batteries may pose safety hazards in situations such as overcharging and overheating, and require an effective safety management system.

　　Cost: Although the price of lithium batteries has been decreasing year by year, the initial investment is still relatively high.

　　Limited resources: Uneven distribution of lithium resources and long-term dependence on imports may bring supply chain risks.

　　Recycling and reuse: The recycling and reuse of retired lithium batteries still need further improvement to reduce environmental pollution.
