High-capacity batteries that charge faster and last longer are key to powering the future of portable electronics, electric vehicles, and long-term energy storage.For the past few decades, lithium-ion batteries have been leading this sphere. A type of rechargeable battery, lithium-ion batteries are charged and discharged by the movement of these ions between the positive electrodes and negative electrodes, i.e., anodes and cathodes.The metal lithium used in these batteries is soft, silvery, and highly reactive. It has the lowest density of all metals and is found in compounds as a mineral, with Chile being its biggest producer. Chile also has the largest lithium reserves, followed by Australia and China; the latter is also a leader in lithium-ion batteries.These batteries actually require huge amounts of water and energy to produce. They are also very difficult to recycle.So, while lithium-ion batteries have proven their performance in portable consumer electronics like smartphones, laptops, and other handheld devices, as well as EVs and storage systems for solar power backup, the market is now searching for materials that can outperform lithium-ion and power the next-generation of devices, long-range vehicles, electric aircraft, and grid-level storage.This has led researchers to aluminum, which shows promising performance for safer, cheaper, and more powerful batteries.Aluminium's Potential in Advancing Batteries Efforts to develop rechargeable aluminum batteries have been going on for many decades now but gained significant traction in the past decade or so. Increased attention and research have helped Al-ion batteries achieve exceptional rates in charging and discharging. All the developments surrounding Al-ion batteries are significant due to the superior benefits this electropositive metal brings to the table. Aluminum's unique properties include being lightweight, corrosion-resistant, and having high thermal conductivity. This versatility has made this metal highly beneficial in a wide range of applications in various industries, notably transportation
