Abstract

As a new energy storage technology, calcium-carbon mineral battery has become a research hotspot because of its advantages of low cost, high safety, potential long cycle life and abundant resources. In this paper, the technical principle, performance characteristics and application potential of calcium-carbon mineral battery in renewable energy storage are systematically analyzed. Calcium-carbon mineral batteries are made of calcium-based materials and carbon-based conductive agents. The working voltage is 2.0-3.5V, the theoretical energy density is 200-400 Wh/kg, which can actually reach 100-250 Wh/kg, and the cycle life can reach 500-1000 times under laboratory conditions. It has high safety, low cost and excellent performance in the range of -20℃ to 60℃. In terms of application scenarios, calcium-carbon batteries are suitable for a variety of settings, including grid-scale, distributed, and mobile energy storage. They can effectively smooth the fluctuations in renewable energy generation, provide stable power to remote areas, and enhance the driving range of electric vehicles. Economic evaluations show that the levelized cost of storage (LCOS) for calcium-carbon batteries is $68/kWh, significantly lower than the $92/kWh for lithium-ion batteries. However, calcium-carbon batteries still face challenges in commercialization, such as technical bottlenecks, an imperfect market and policy environment, and an immature industrial chain. In the future, further optimization of materials and processes, improvements in battery performance, and the establishment of stronger policy support systems will be necessary to promote the widespread adoption of calcium-carbon batteries.
