Batteries based on multivalent ions (Mg2+, Al3+, etc.), are among the potential candidates for future cost-effective energy storage devices. However, development of these batteries is hindered by the lack of efficient electrolytes and cathode materials. Among various multivalent-ion batteries, rechargeable aluminum batteries are promising alternative energy storage devices due to the low-cost and abundance of aluminum. In addition, aluminum can be handled in open air, providing easier cell fabrication processes and elimination of some of the safety issues associated with lithium and sodium ion batteries. Very few cathodes such as Vanadium Oxide, Chevrel phase (Mo6S8), and TiS2 are known that can host the high charge density Al3+ ions. These materials usually suffer from low capacity, low voltage, and low cycle life with significant capacity decay over 100 cycles. Here we present two-dimensional (2D) transition metal carbides (called MXenes) as potential cathode materials for rechargeable aluminum batteries. The video explains the MXene materials and our process for making an aluminum battery based on them.
"The photos of Tesla cars or other products used in this video to demonstrate the flammability of Li-ion batteries does not implicate or promote any defects or flaws or lack of reliability in those products. The Tesla's battery technology is among the bests in the world and is not comparable in any aspects to the lab-scale battery technology we are developing"
