As demand and supply curves shift, prices adjust to maintain a balance between the quantity of a good demanded and the quantity supplied. If prices did not adjust, this balance could not be maintained. Notice that the demand and supply curves that we have examined in this chapter have all been drawn as linear.

For instance, under the NZE scenario and assuming 75 kWh NMC811 battery packs, the Li, Co, and Ni demand will be 7, 8, and 11 multiples, respectively, of the supply figures in 2022 (Figure 4). This requires a considerable acceleration in building up the production capacities compared to the 2016–2022 period during which the supply of Li, Co, and Ni only
EVs accounted for over 90% of battery use in the energy sector, with annual volumes hitting a record of more than 750 GWh in 2023 – mostly for passenger cars. Battery storage capacity in the power sector is expanding rapidly. Over 40 gigawatt (GW) was added in 2023, double the previous year''s increase, split between utility-scale projects
Carbon 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 [1].To cope with global climate changes and energy supply shortages and to achieve carbon emission reductions, developed countries must adjust development strategies

In March 2019, Premier Li Keqiang clearly stated in Report on the Work of the Government that "We will work to speed up the growth of emerging industries and foster clusters of emerging industries like new-energy automobiles, and new materials" [11], putting it as one of the essential annual works of the government the 2020 Report on the Work of the
Supply-demand equilibrium In the supply and demand stage of the WPH hybrid power generation operation system, there are often multiple participants cooperating in the interest competition. Dong et al. analyzed the subject cooperation space and the fair distribution of interests in the two stages of power supply and demand.
In recent years, the mutual adjustment and mutual influence between the supply and demand of power lithium-ion batteries have gradually narrowed the gap between supply and demand. It is also worth noting that from the perspective of the loss in material flow, the power lithium-ion battery of stock in EVs has a decreasing trend.
The power supply of energy in turn affects the actual power generation of the power station. Therefore, the supply and demand links in the industrial chain not only pursue their own interests, but also inevitably lead to the causal relationship between the master and the slave.
The ever-increasing demand for electricity can be met while balancing supply changes with the use of robust energy storage devices. Battery storage can help with frequency stability and control for short-term needs, and they can help with energy management or reserves for long-term needs.
The utilization of new energy with large scale is a recognized development trend. Therefore, with the increase of the proportion of new energy in the power system, the structural characteristics and operation control methods of the traditional power system will have a essential change, thus forming the new energy power system.
Batteries are set to play a leading role in secure energy transitions. They are critical to achieve commitments made by nearly 200 countries at COP28 in 2023.
