eliminating dendrite formation

[Sparky]

Info. on the zinc-nickel oxide and zinc-manganese dioxide rechargeable batteries .

-for all its benefits, zinc has one major shortcoming — dendrite formation develops over the battery’s life, causing the battery to short after a few hundred cycles. ----------Inexpensive, non-toxic and widely available, zinc has long been known to be an excellent electricity storage material because of its high energy density. Invented more than 100 years ago, the zinc anode battery is still used today.

Energy Institute began developing innovative solutions for this problem in 2008. The result: a zinc-nickel oxide battery in which the electrolyte circulates constantly, eliminating dendrite formation and preventing battery shortages. This breakthrough helped the CUNY Energy Institute create a zinc battery that has a round trip efficiency of 85 percent, and can be charged and discharged more than 5,000 times.-----------the zinc-nickel oxide battery a quarter of the cost of conventional lead-acid batteries per cycle.

the zinc-manganese dioxide battery will be even more cost-effective than the company’s zinc-nickel oxide batteries.------a zinc-manganese dioxide battery that is half the weight and five times the life of a lead-acid battery, without the manufacturing, handling and recycling costs of lead-acid batteries.
