In the field of energy storage, aluminum-based lead-carbon batteries are gradually emerging as a new technology that has attracted much attention. This technology is an evolution of traditional lead-acid batteries, combining the advantages of lead-acid batteries and supercapacitors, with high specific energy, good charge-discharge performance and long service life. The following is an analysis of the technical characteristics and market prospects of aluminum-based lead-carbon batteries in the field of energy storage.
Technical features:
High security
Aluminum-based lead-carbon batteries mainly use dilute sulfuric acid aqueous solution as the electrolyte, which will not cause thermal runaway and spontaneous combustion explosion, and has higher safety than lithium batteries. This makes it a significant advantage in applications where security is critical.
Long-term energy storage capacity
Aluminum-based lead-carbon batteries optimize energy density and power density by adding capacitive activated carbon to the anode material, and have long-term energy storage capabilities. The aluminum-based lead-carbon battery developed by Kungong Technology has a power storage time of more than 120 hours, which can meet the needs of long-term energy storage.
Low cost and high reliability
Aluminum-based lead-carbon batteries have excellent performance in terms of cycle life, cost performance, low-temperature performance, production and recycling technology. Its low cost and high reliability meet the national requirements for low-cost, high-reliability and long-life energy storage technology.
Environmental protection and sustainability
The residual value recovery rate of aluminum-based lead-carbon batteries can reach 50%, and the positive and negative electrode materials and electrolytes of the battery can be recycled, which has a low life cycle environmental load.
Market outlook
domestic market
Kungong Technology has made remarkable progress in the field of aluminum-based lead-carbon batteries. Its first international aluminum-based lead-carbon long-term energy storage battery production line in Luliang, Qujing, Yunnan Province has an annual production capacity of 5GWh, and the first phase of the 10GWh production line in Lingwu City, Yinchuan, Ningxia is also about to be put into operation.
International market
Kungong Technology's aluminum-based lead-carbon battery energy storage inverter all-in-one machine has been successfully exported to Uzbekistan, and has carried out in-depth cooperation with Zambia, Congo (DRC) and other countries along the "Belt and Road", highlighting the wide recognition of aluminum-based lead-carbon batteries in the international market.

Policy support
The national "14th Five-Year Plan" New Energy Storage Development Implementation Plan clearly lists lead-carbon batteries as one of the key core technologies, and promotes their research and application. The National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) have also proposed to improve the innovation capacity of new energy storage technologies and promote the development of technologies including lead-carbon batteries.
Application scenarios
Aluminum-based lead-carbon batteries perform well in multiple energy storage application scenarios, including:
C&I energy storage: It has a difficult position in energy storage applications such as underground spaces, densely populated areas, and data centers with high safety requirements.
Distributed photovoltaic project: In the first "photovoltaic and storage integration" distributed photovoltaic project in Yunnan Province, Kungong Technology has an installed capacity of 6.2MW and a 0.5MW/2MWh aluminum-based lead-carbon electrochemical energy storage system, demonstrating its determination and strength to promote the development of high-safety and green energy.
Large-scale energy storage clusters: Lead-carbon energy storage power stations with a single installed capacity of more than 100MW have become common, and large-capacity and long-term are the two characteristics of lead-carbon energy storage projects.
Future outlook
With the increasing maturity of aluminum-based lead-carbon battery technology, its application in the field of energy storage will continue to expand. It is estimated that the global new energy storage demand will reach 163GW/511GWh in 2025, and the energy storage market space will exceed 600 billion yuan. The layout of Kungong Technology and other enterprises in the field of lead-carbon batteries, the energy storage business may become a new performance growth point for the company in the future.
