What is the color of new energy? Battery pollution affect human health

We have to eliminate the pollution of the environment and the development of automotive fuel new energy vehicles, but used in the production and recycling process of batteries pollution affect human health, it worth it?

Fuel cell, hybrid, electric three series of new energy vehicles, hybrid vehicles required in addition to oil, the rest do not have oil. The former with hydrogen, the latter with the electrical, it was known as green products (hybrid can cut emissions.)

It is envisaged that the electricity to charge the battery from hydro, wind, sunlight, nuclear energy of the electric power, thermal power is also the valley at night using its power. This green and renewable power, of course. Hydrogen from renewable electricity manufacturing. Of course, the hope that one day these ideas can become reality. Three series of cars required battery storage of electricity, or auxiliary drive vehicle, or the main drive vehicle. The battery is currently the industry primarily lithium battery. In the hybrid on the original nickel-metal hydride batteries in the main, pure electric vehicles using lead-acid batteries Uehara.

Now the industry on several batteries or a dispute, one is better then the length of each. Energy ratio than lithium-ion battery power, fast charge discharge can quickly adapt to a very large temperature range. In recent years, greatly enhancing performance, the cost has decreased substantially, it is high expectations. But there are relatively more constraints, is developing technology to be developed by research

World reserves of 15 million tons of lithium resources, China about 390 million tons, accounting for about 28% of the world's total, ranking second in the world. It is estimated that, 1g lithium metal can be stored electricity of about 0.6 ~ 0.8Wh, (and synthesis of cathode materials, but not with synthetic materials on the negative, and synthesis related to the performance electrolyte).

To a compact car, for example, power consumption per drive about 15 100km of electricity, continues the course of about 150km or so, the lithium storage capacity at 30kW / h ~ 35kw / h or so, the group of lithium metal, lithium content in 50kg above, approximately equal to a cell phone battery (rechargeable batteries 3.5Wh) of 10,000 times. 121 Beijing Road, a large demonstration of pure electric passenger, the total storage capacity of its lithium battery is said to 160kW / h, total weight about 2 tons, the lithium metal content is about 280kg or so.

Toyota Prius hybrid is the use of nickel-metal hydride batteries, but not storage capacity. Small reserves of nickel metal is used in electroplating, coinage, must be made of stainless steel materials. Lead-acid batteries oldest and most mature, a lot of maintenance-free type has been widely used for electric two-wheeled vehicle, the charge can 3C current charge and discharge in 2 hour rate discharge current. Lead is rich in resources, China are large, accounting for about 40% of the world's total. However, the extraction of lead metal, lead plate manufacturing, battery assembly, and recycling of waste batteries, renewable various aspects of workers harmful to the environment pollution. The consequences are increasingly shows that after a century of lead-acid batteries, enduring, with its need for energy storage room is mainly used in the ground, a large number of used vehicles must be controlled.

Lithium, nickel limited resources, needed a place too much power for the car battery is a throwaway, not a road to sustainable development. With lithium, nickel resources to replace much of the oil resources, it is not a wise move. Lead-acid batteries can not be avoided pollution, less able to do the best. It has come to replace the pollution emissions of the greenhouse gases produced internal combustion engine, there really is a tiger to wolf.

If we do lithium, nickel metal battery powered, equipped with the new energy vehicles, and this is also the industrialization of new energy vehicles, but also exported, then this resource enough a few years? Should not be used for other purposes? (A group of transit buses for the 2 tons of lithium, and lithium metal of about 280kg. Ni-MH battery of about 4 tons, and its nickel how much, no one has published data).

If we use lead-acid battery equipment, electric cars, electric buses, but also have to change a battery a year, that amount to be shocking. Beijing bus a bus lead-acid batteries weighing about 6 tons, a compact car to be a few hundred kilograms, (lead-acid battery is maintenance-free type of its storage capacity 35--40Wh/kg, while riding a bus if 60, the number of its load of quality, certainly not 6 tons. This 6 tons of battery in the car of its day, and from the camel, its technical surely unreasonable, undesirable.

We develop new energy vehicles (electric), as an alternative to oil for the purpose on tight, and to consume fewer resources, lithium, nickel metal, which science? Feasible? We have to eliminate the pollution of the environment and the development of automotive fuel new energy vehicles, but used in the production and recycling process of batteries pollution affect human health, it worth it?

So now if you want to use this new energy vehicles, energy storage devices and storage approach is necessary to discuss some of the. Currently in the demonstration prototype stage, turned too late. "DDT" jokes do this again.
