Today most users try to live with our lithium ions batteries, but there is not denying that the current capacity they offer is unable to meet the energy needs of devices on the market. The perfect battery still remains as elusive as an Utopian world, but many laboratories are working to find a solution that can revolutionize portable devices, such as the one in Stanford University.

The Stanford University lab is working on a battery of made of aluminum ions, which carries a much lower cost because aluminum is cheaper to manufacture than lithium. It is also much more stable than lithium, with researches demonstrating the fact by drilling into the new battery while it was discharging to show its stability. The new aluminium batteries is said to offer much faster charge times over current lithium ion batteries, with charge times as low as 1 minute for a regular smartphone sized battery.

This is not the first aluminum battery that has been developed, but this time, the Stanford prototype is able to maintain its capacity after 7,500 cycles (7.5 times longer than a lithium ion battery). Unfortunately there are odds against this new technology, the chief one being that it can only produce about 2 volts or a capacity equivalent to 40 watts per kilogram, an amount that is well below 206 watts per kilogram achieved by lithium ion batteries. Researchers admit that improving the cathode material could get better density, but on the other hand, issues such as the high stability it offers, charging times or large life cycles involve significant progress to be an early version battery.

Here’s to hoping that the researchers at Stanford University achieve their goal in the near future so we can get our hands on these aluminium ion batteries and not have to worry about carrying phone chargers or look for power outlets anymore.
