Mobile devices, electric vehicles, and grid-connected energy storage systems rely heavily on lithium-ion batteries. But a research team in China has developed a battery that uses calcium metal, promising an alternative and a competitor to lithium technology.
New battery solution could "dethrone" lithium-ion for a long time.
Compared with lithium-ion, the team believes this type of battery could be cheaper and safer, while also avoiding some of the lithium supply chain issues that are currently being addressed due to mining space and the environment.
However, this technology has not yet entered the stage of widespread commercialization. The research team also pointed out that calcium-oxygen batteries are still not stable at room temperature and still need to improve the electrolyte and related materials to meet the conditions of practical application.
Meanwhile, lithium-ion still plays a dominant role thanks to its proven advantages such as high energy density, relatively stable charging and discharging capacity and developed production ecosystem. However, many studies show that lithium-ion batteries still face challenges such as raw material costs, safety and recycling.
Developing calcium batteries not only offers advantages in terms of raw materials (calcium is more abundant than lithium), but also has the potential to reduce safety risks. In the report, the team emphasizes: “The proposed calcium-oxygen battery is stable in air and can be fabricated into flexible fibers…”
While the technology is still some way from the lab to mass production, it offers an important direction for energy strategy, especially as demand for energy storage and electric vehicle adoption continues to grow rapidly worldwide. Once successfully commercialized, calcium-ion batteries or their equivalents could replace some or all of the role of lithium-ion, reducing costs for consumers and businesses.
However, there is still much work to be done to make this technology a reality: perfecting the materials, improving the lifespan, ensuring multiple charging and stability at real-world ambient temperatures. In addition, developing a compatible supply chain, manufacturing and recycling are also significant challenges.
