Researchers in Beijing have developed a safer, more sustainable alternative to lithium-ion batteries using aluminum. The new aluminum-ion battery design boasts an extremely long lifespan, retaining 99% of its capacity after 10,000 charge/discharge cycles compared to 80% for typical Li-ion batteries. The solid-state electrolyte makes the battery safer and leak-proof, even in extreme conditions like high temperatures. Additionally, the battery is highly recyclable, with up to 80% recovery of materials in lab experiments. While the battery’s energy density still needs improvement, this breakthrough has the potential to revolutionize industries from automotive to renewable energy.
