Furukawa wants to reduce the price to of the salt-water system to half the cost of a conventional lead acid battery.
On that crucial dimension, if lithium-ion batteries are a 3, the next best technology, NiMH is a 2, and a lead acid battery, like the one you use in your car, gets a 1.

The venerable and ridiculously cheap lead-acid battery that starts your car every time with stunning reliability should tell you something.
The microgrid comprises eight 100-kW grid-tied inverters, the rooftop PV array, the lead-acid battery pack, backup diesel generators, and a Web-based monitoring and control system.

Power Technology is on the verge of producing what it claims is a revolutionary lightweight lead-acid battery but has yet to find any potential customers.
The lead-acid battery is one of the triumphs of 19th-century technology.
That much has been known since the lead-acid battery was invented.
The first reason was that the lead-acid battery packs used in the EV-1 weighed 1600 lb. and were both too heavy and not powerful enough for widespread use.
The strongest sector was base metals, with lead imports in August rising 51 percent year over year, supported by very strong demand from lead acid and battery makers.
This would eliminate what has historically been the only performance advantage of lead acid in starter battery applications, and is expected to considerably increase the value proposition of A123's Engine Start battery as a lighter-weight, longer-lasting alternative to absorbent glass mat (AGM) and other lead acid batteries.

"Based on our analysis, the performance of A123's new Nanophosphate EXT at high temperatures is unlike anything we've ever seen from lead acid, lithium ion or any other battery technology, " said Dr. Yann Guezennec, senior fellow at CAR and professor of mechanical engineering at the Ohio State University.

Its original nickel-metal-hydride battery packs have been replaced with lead acid batteries to extend the distance the car can travel on electricity.
This week ARPA-E announced it is funding General Atomics to build a flow battery using well-known, and cheap, lead acid chemistry.
