Do lithium batteries have more low-carbon and environmentally friendly than lead-acid batteries?

If there is no lead accumulator battery, more than 100 million Chinese electric bike will not be able to start, and more than 10 mobile phones can't use normally. With the rapid development of automobile, ship and communication industry, as high cost performance of the power energy, lead battery has been developing rapidly. However, because lead-acid battery contains heavy metal lead, its production and recycling may lead to pollution by any carelessness. The contamination caused by Lead battery is not in the storage battery using process, but in the production and recycling process. National lead battery recycling network has not built, so 80% share of the recycle flow to the self-employed.

How to find not only ensure extraction regenerated lead is used in the production, reduce the consumption of resources, and to minimize the environmental pollution, keep the coordinated development of economy and the environment balance for all concerned about the people thought of environmental protection.

A surprising number of hundreds of millions of batteries face of retrieving and dismantling

In an electric car flower shop, electric car owner Mr Liu said to the reporter, his electric car was bought in early 2014, just a month ago in the lead battery. When asked about the old battery to, he said that with 30 piece price for vendor sold for recycling.

Reporters in multiple electric outlets did not see the waste battery recycling business, only to old change new, each lead battery up to 10 yuan to 20 yuan, and some waste collection at RMB 20 to 40 yuan price recycling waste lead accumulator has the advantage of price. According to relevant data show that 80% share of the lead battery recycling waste to Soho.

Electric bicycle is considered to be low carbon, environmental protection way to travel. But at present most of the electric bicycle is used lead-acid battery, scrap if mishandled, after will cause incalculable pollution to environment. According to the China bicycle association, according to figures released in 2012 electric bikes in China has reached 140 million cars. At the same time, the use of lead-acid batteries is not only the electric bicycles, including growing car race.This means that, maybe two years later, there will be hundreds of millions of pieces of battery pack face of retrieving and dismantling.

Current situation is grim

Lead smelting method has become a natural environment

Reporters had three survey small lead smelting factory, field witnessed the 11 small workshops lead smelting process. Simply summarized small lead smelting technology on the "six", namely "a hammer to knock lousy scrapped lead-acid storage battery plastic shell, a LiuKuang collect scrap lead plate, a cauldron of smelting of lead slag, collected a milling for smelting iron added fuel, a blower for the regeneration of lead smelting heating model, a set of iron smelting casting good lead water".

Reporter found that some of a large number of individuals are hidden in the underground remelted lead point, are unwrapped battery, lead acid and place a pour, began to open up a crucible smelting lead, this is a lot of lead smelting method of "process". These small workshops are not regular business and tax registration, and the low production level, there is no ability to control pollution, smelting waste, waste gas and optional processing, become the new sources of pollution, environmental violations, become very headache for regulators regulatory blind Angle.

Lead battery components including lead plate, acidic electrolyte and plastic shell. Many vendors are only lead recycling, will acid emissions at random, then lead to sell some illegal smelters, caused the secondary pollution, resource comprehensive utilization rate is low. In addition, acid untreated emission can cause the pollution of water, soil, illegal smelting process can cause air pollution, the human long exposure to high lead environment can cause excess lead levels in the body, and even lead poisoning, damage the brain nerve system, also affect the hematopoietic function, and kidney and bone.

These small workshops of lead-acid battery recycling indeed can be referred to as natural environment, and it is the serious pollution of small workshops, became more blood lead incidents.

Because an individual recycling to high-priced recycling, simple disassembly for profit, the current domestic several formal discarded lead-acid battery recycling and dismantling enterprises encounter difficulties, enterprises do not have enough to eat, recycling quantity seriously insufficient.

Lead-acid battery recycling needs policy support

One would not reveal the name of environmental protection, waste lead-acid batteries of retrieving and dismantling innocuity treatment has reached the point where they cannot be ignored. According to introducing, at present domestic building official waste lead-acid battery recycling dismantling regeneration enterprises only 10, annual capacity of 400000 tons, only the rest of the 1.6 million tons of waste lead acid battery by individual enterprises of retrieving and dismantling.

The environmentalists told reporters in the industry, to break the lead-acid battery disposal problems, first of all to start from the fundamental source. Environmental protection departments should urge relevant enterprise comprehensive waste management parameter, the master of waste lead acid battery production and sales channels, to urge enterprises actively to formal for dismantling. The second is to make a proper policy for formal recycling companies, tax and financial support. Has the qualification of formal enterprises to carry out the recycling of waste lead acid battery business, high cost and public property. Encountered in the enterprise is difficult to overcome the trouble, the government should give subsidies, so as to ensure the normal operation of enterprises, let the equipment efficiency into full play.

Another industry insiders suggest that it is in urgent need of the state environmental protection department under the unified support to establish a national waste lead acid battery recycling and dismantling industry association, unified price, fundamentally eliminate confusion now raise the price of each other, can be set by the trade associations of a unified market guide the purchase price.

The personage inside course of study also suggested that, as soon as possible to establish and perfect the recycling of dangerous goods regulations, strictly regulate the waste lead-acid batteries, and the qualification cognizance of the hazardous waste recycling. For industry and commerce, public security departments to unite, to have recognized qualifications of individuals or individual recycling to a harsh crackdown, firmly ban illegal vendors for recycling waste lead acid battery and dismantling, ensure the waste lead-acid batteries by more formal enterprises of retrieving and dismantling.

No pollution. The lithium battery cost is high

A link to the

The reporter understands, the domestic production of electric cars, more than 90% with lead-acid batteries. Various studies have shown that emerging lithium battery than conventional lead-acid battery is more environmentally friendly.

According to the classification of the lead-acid battery industry belongs to the downstream of the non-ferrous metal industry one of the most polluted in the industry, the character with strong force and non-biodegradable contamination has been to ridicule. Late in the production of the emissions of waste acid, waste alkali, waste water pollution of the water can be high. In comparison, the lithium battery have a natural advantage in environmental protection, because of its raw materials do not contain heavy metals polluting, the production process does not produce pollutants.

Electric car industrialization practice has shown that the environmentally friendly rechargeable batteries such as lithium battery energy and high power density, long service life, manufacturing, use and low recovery phase, high recovery efficiency, can already for lead-acid batteries.

On the lithium battery in the environmental performance, however, have the advantage of congenital li-ion battery electric vehicle sales have far less lead-acid battery electric vehicle, to this, the personage inside course of study says, because of cost, lead-acid battery is still in recent ten years will be the mainstream market, lithium battery for lead-acid battery replacement will need a long period of transition.

The experts also said that the lithium battery and lead acid batteries belong to the non-biodegradable material, therefore, even if it is no harm in environmental protection basic waste lithium-ion batteries, the citizens also should be discarded to the designated waste battery recycling, unified handling by the relevant departments.
