Aluminum has many advantages, such as light weight, corrosion resistance and electrical conductivity. Engineers at the Georgia Institute of Technology are also using the material to improve lithium-ion batteries. Their new system could enable electric vehicles to run longer on a single charge and would be cheaper to mass-produce.
A good battery needs two things: high energy density to power devices, and stability, so it can be safely and reliably recharged thousands of times. For the past three decades, lithium-ion batteries have reigned supreme.
