Batteries Going Green

For years, battery manufacturers have been developing ways to make their products more environmentally friendly.

Companies look for alternatives to the harmful substances used today. However, that strategy will take decades to commercialize; producing batteries that are stronger and more efficient seems the best option.

Presently, researchers are exploring “bio-batteries”, using substances made from living organisms to power objects.

In 2007, Sony developed a “bio battery” that generates electricity from sugar. This discovery uses carbohydrates and enzymes to generate power and has a maximum output of 50 milliwatts,giving it the capability to power a walkman. This has set path in turning to abundant living organisms to reduce toxic waste produced by batteries. (Sugar fuelled battery..,2007)

A recent development by a research team in Aarhus University in Denmark creates a bacteria colony that reacts with mud and seawater to generate electricity. The bacteria colony works by having contact on top with oxygen while the bottom contacts the organic material. Because both layers are somehow connected in the process, the bottom layer that produces electrons are transported to the top layers therefore reacting with oxygen. Scientists are trying to harvest the nanowire network that these bacteria creates to potentially developing a living biogeobattery (Anupanm, 2010).

Meanwhile, scientists at the University of Leicester are looking for ways to replace harmful, carcinogenic, toxic acids and electrolytes currently and widely used in many commercial metal finishing and energy storage processes (University of Leicester, 2010). So far they have developed ionic liquid solvents that are non-toxic as an alternative to dangerous solutions. Karl Ryder, a senior lecturer at the University who oversees the project explains, “One of our aims is to improve the working environment for people within the manufacturing industry by replacing unpleasant acids or caustic processes with ionic liquids. The user experience is very similar for both and no additional equipment or training is required, but the user benefits from a more pleasant and safer working environment.” (University of Leicester, 2010). The team of researchers received a €1 million funding distributed between several major projects.

One project called POLYZION was to develop an eco-friendly and affordable rechargeable battery for electric vehicles. It is designed to be sustainable, having light-weight characteristics as opposed to existing batteries that use heavy, expensive materials that can be harmful to the environment (University of Leicester, 2010).

Additionally, MIT researches are developing ways to manufacture liquid metal batteries made using earth-abundant elements. A big issue scientists faced in an attempt to develop eco-friendly batteries is the high cost of the material. MIT attempts to tackle this problem by using substances that are plentiful. As a result, the research team developed a small battery made from antimony and magnesium in between an electrolyte. As for now, the battery is not beneficial to small devices, but researchers continue to develop the product to a larger scale (Anupam, 2010 March 19).

Moreover, leading battery producers such as Fuji created the EnviroMAX batteries last year that do not contain ingredients harmful to the environment such as cadmium and mercury. They are packaged with recycled paper and PET plastic which makes the products degradable where they can be disposed normally. This decreases the costs incurred from recycling batteries (Hanlon, 2009).

Hitachi Vehicle Energy Ltd. Created a new Lithium-ion battery designed for automobiles. This new product has more capacity up to 25 Ah that is about 5 times more than its predecessors. It produces energy of up to 120 Wh/kg and power density of 2,400 W/kg. It further provides heat-resistant features preventing internal short circuits and increasing safety (Madan, 2010).

The market today focuses on the emerging green market. Companies spend millions on the research and innovation sector to develop methods of increasing efficiency to reduce waste, or finding abundant alternatives to current methods. Many have succeeded, but may take time until the developments are released to the masses. Nevertheless, the decision remains in the hands of consumers to persistently push towards the eco-friendly movement.

Nanoporous Materials: Science and Engineering

Product Description
Porous materials are of scientific and technological importance because of the presence of voids of controllable dimensions at the atomic, molecular, and nanometer scales, enabling them to discriminate and interact with molecules and clusters. Interestingly the big deal about this class of materials is about the “nothingness” within — the pore space. International Union of Pure and Applied Chemistry (IUPAC) classifies porous materials into three categories — micropores of less than 2 nm in diameter, mesopores between 2 and 50 nm, and macropores of greater than 50 nm. In this book, nanoporous materials are defined as those porous materials with pore diameters less than 100 nm. Over the last decade, there has been an ever increasing interest and research effort in the synthesis, characterization, functionalization, molecular modeling and design of nanoporous materials. The main challenges in research include the fundamental understanding of structure-property relations and tailor-design of nanostructures for specific properties and applications. Research efforts in this field have been driven by the rapid growing emerging applications such as biosensor, drug delivery, gas separation, energy storage and fuel cell technology, nanocatalysis and photonics. These applications offer exciting new opportunities for scientists to develop new strategies and techniques for the synthesis and applications of these materials.

This book provides a series of systematic reviews of the recent developments in nanoporous materials. It covers the following topics: (1) synthesis, processing, characterization and property evaluation; (2) functionalization by physical and/or chemical treatments; (3) experimental and computational studies on fundamental properties, such as catalytic effects, transport and adsorption, molecular sieving and biosorption; (4) applications, including photonic devices, catalysis, environmental pollution control, biological molecules separation and isolation, sensors, membranes, hydrogen and energy storage, etc.
