And my work on this came to look in particular at the scrap metal trade — as a major economic force behind many of these accidents. In this short talk I would just like to highlight some of the key elements of this phenomena.

Making high-performance batteries from junkyard scraps by David Salisbury Nov. Cary Pint, right, Andrew Westover and Nitin Muralidharan, who is holding the prototype junkyard battery they created in his left hand.

Company Introduction

He and Westover are holding bottles of the common household chemicals used in the process. The secret to unlocking this performance is anodization, a common chemical treatment used to give aluminum a durable and decorative finish.

When scraps of steel and brass are anodized using a common household chemical and residential electrical current, the researchers found that the metal surfaces are restructured into nanometer-sized networks of metal oxide that can store and release energy when reacting with a water-based liquid electrolyte.

They tested it for 5, consecutive charging cycles — the equivalent of over 13 years of daily charging and discharging — and found that it retained more than 90 percent of its capacity.

Unlike the recent bout of exploding lithium-ion cell phone batteries, the steel-brass batteries use non-flammable water electrolytes that contain potassium hydroxide, an inexpensive salt used in laundry detergent. The research team is particularly excited about what this breakthrough could mean for how batteries are made in the future.

So far, batteries have remained outside of this culture, but I believe we will see the day when residents will disconnect from the grid and produce their own batteries. It consisted of a ceramic terracotta pot, a copper sheet and an iron rod, which were found along with traces of electrolyte.

Prototype of high-performance junkyard battery powering a small light. The researchers next step will be to produce a full-scale version suitable for use in energy-efficient smart homes.

Scrap Metal Recycling The Scrap Metal Recycling industry has exhibited high volatility over the past five years.

Since the industry is highly susceptible to swings in global commodity prices, industry revenue spiked when steel, aluminum and copper prices rose after the downturn.
