The finance group revised its global battery demand growth projection to 29% for 2024, down from the previous estimate of 35%, with a 31% growth expected in 2023. Goldman also forecasts a 40% reduction in battery pack prices over 2023 and 2024, followed by a continued decline to reach a total 50% reduction by 2025-2026.
In 2023, the supply of cobalt and nickel exceeded demand by 6.5% and 8%, and supply of lithium by over 10%, thereby bringing down critical mineral prices and battery costs. While low critical mineral prices help bring battery costs down, they also imply lower cash flows and narrower margins for mining companies.
LFP production and adoption is primarily located in China, where two-thirds of EV sales used this chemistry in 2023. The share of LFP batteries in EV sales in Europe and the United States remains below 10%, with high-nickel chemistries still most common in these markets.
LFP is the most prevalent chemistry in the Chinese electric car market, while NMC batteries are more common in the European and American electric car markets. China’s current leading role in battery production, however, comes at the cost of high levels of overcapacity.
In contrast, LFP batteries have a lower residual value after recycling, which could put pressure on recycling business models. Nonetheless, regulations can fill this gap by either incentivising or mandating the recycling of end-of-life batteries regardless of their residual value.
In 2023, the global EV fleet consumed about 130 TWh of electricity – roughly the same as Norway’s total electricity demand in the same year. Zooming out to the global scale, EVs accounted for about 0.5% of the world’s total final electricity consumption in 2023, and around 1% in China and Europe.

China Tower is a world-leading tower provider that builds, maintains, and operates site support infrastructure such as telecommunication towers, high-speed rail, subway systems, and large indoor distributed systems. As of June 2019, China Tower boasted a combined 1.954 million sites with a value of 315.36 billion yuan. . In Hangzhou, the 5G Power solution deployed by China Tower and Huawei supports one cabinet for one site and boasts smart features like intelligent peak shaving, intelligent voltage boosting, and intelligent energy storage. . China Tower and Huawei conducted joint pilot verification in 2018 and found that the 5G Power solution could support effective 5G site deployment. [pdf]
Therefore, the base station energy storage can be used as FR resources and maintain the stability of the power system. The base station is the physical foundation for the popularity of 5G networks. 5G base stations distribute densely in cities.
Base stations for renewable energy powered sustainable 5G networks should always remain connected to the power grid for continuous energy supply. However, this strategy is not environmentally friendly and could result in higher energy costs, as during renewable energy deficits at the base stations, energy has to be procured from the power grid even when its cost is high.
In [ 20 ], the energy saving strategy of base station is proposed considering the variability and complementarity of base station communication loads. This strategy helps the power system to cut peaks and fill valleys while reducing base station operating costs.
Although the power output of a single base station storage is limited, the combined regulation of large-scale base stations can have a significant meaning. Therefore, the base station energy storage can be used as FR resources and maintain the stability of the power system.
In the optimal configuration of energy storage in 5G base stations, long-term planning and short-term operation of the energy storage are interconnected. Therefore, a two-layer optimization model was established to optimize the comprehensive benefits of energy storage planning and operation.
The nominal capacity of the base station energy storage is 20 kWh, and the number of the base station in each operating state is 500. The SOC values of the base station obey normal distribution between 0 and 1 in each operating states. This paper takes \ ( {\text {SOC}}_ { {i,\min }} = 0.3 \) and \ ( {\text {SOC}}_ { {i,\max }} = 0.9 \).
