My phone showed me a Daily Mail article about a British engineer that designed these batteries, but I don't know how good a source the Daily Mail is, and they use their words weirdly. Here's an article explaining how he developed this technology 18 years ago, but nobody in England would pay attention. France felt it was their nation's best interest to support him, but after two years, England convinced him to come back, only to waste his time. They say that he cannot get anywhere because everyone is obsessed with lithium. It sounds like this is a completely different type of battery, the aluminum is consumed in the process, although still reusable. It cannot be recharge, you would swap batteries after fifteen hundred miles!
