Sodium-ion Battery is the core technical support for achieving the dual carbon goals (carbon peak and carbon neutrality), and has extremely important strategic significance for promoting the transformation of energy structure, reducing carbon emissions, and achieving the dual carbon goals. First of all, sodium batteries promote the large-scale development of new energy: new energy power generation such as wind power and photovoltaic is the core of achieving the dual carbon goals, and the sodium battery energy storage system can perfectly solve the problem of intermittency and volatility of new energy power generation, realize peak shaving and valley filling, frequency modulation and voltage regulation, greatly improve the grid-connected utilization rate of new energy, reduce wind and light abandonment, promote the large-scale development of new energy power generation, replace the traditional high-pollution fossil energy power generation, and reduce carbon emissions from the source; secondly, sodium batteries promote the electrification transformation of the transportation field: sodium batteries can completely replace lead-acid batteries, and are widely used in two-wheeled electric vehicles, low-speed four-wheeled vehicles, entry-level new energy vehicles, promote the electrification transformation of the transportation field, and reduce the carbon emissions of fuel vehicles; thirdly, sodium batteries are green and low-carbon throughout the whole life cycle: the raw materials of sodium batteries are non-toxic and harmless, the production process has no high pollution emissions, and the waste batteries can be efficiently recycled and regenerated. The carbon emissions throughout the whole life cycle are far lower than those of lithium batteries and lead-acid batteries, which meets the development requirements of green and low-carbon; fourthly, sodium batteries promote the construction of new power systems: sodium batteries are the core energy storage components of the new power system, which can build a new power system with new energy as the main body, realize the clean, low-carbon, safe and efficient use of energy, and is the core infrastructure for achieving the dual carbon goals. On the whole, the development of sodium batteries will promote the realization of the dual carbon goals from multiple dimensions such as energy production, energy consumption, and energy storage, and is an indispensable core technical support for the dual carbon strategy.
