Yet another contender for micro-hybrids?

As concerns over fuel consumption grow, micro-hybrid cars are destined to take over the roads, at least in Europe. Ruth Williams finds out how nickel-zinc could out-perform lead-acid in start‑stop technology.

Edison first patented the nickel-zinc couple as a battery concept in 1901, but since then its short cycle-life meant its niche has been in button cell rechargeable batteries. This is far from the automotive world but now PowerGenix believes that with the rise of start-stop technology the improved charge acceptance of nickel-zinc could . . .
