The battery cells were fabricated by adapting a process developed by another team at the university which is designed to make it faster to recharge the batteries than lithium ion (Li-on) and nickelmetal hydride (NiMH) equivalents.
With all the electronic devices in our lives these days, it makes environmental (and financial) sense to switch to rechargeable nickelmetal hydride (NiMH) and lithium ion (Li-Ion) batteries.
