What are the environmental advantages of lithium battery packs over batteries? Environmentally friendly batteries are high-performance, non-polluting batteries that have been put into use or are being developed in recent years. For example, compared with batteries, lithium battery packs are more energy-efficient, environmentally friendly, and pollution-free. However, there is still a big controversy as to whether lithium batteries are really environmentally friendly. This article will add some opinions for reference only.

Compared with lead-acid batteries, what are the environmental advantages of lithium battery packs?

Lithium batteries and lead-acid batteries

Lead-acid batteries used in traditional electric vehicles will produce a lot of pollution and lead vapor when they are discarded. According to statistics, a group of waste batteries from electric vehicles can pollute tens of thousands of tons of water. Lead is not easy to be excreted from the body, and it can also cause metabolic, reproductive and neurological diseases in the human body. If the lead content in the body exceeds the standard, it will lead to mental decline, fetal malformations, and it is easy to induce malignant tumors and even death in children.

What are the environmental advantages of lithium battery packs compared to batteries?

Compared with batteries, lithium battery packs have natural environmental advantages. Lithium battery packaging materials do not contain cadmium, lead, mercury and other harmful heavy metals polluting metals. Lithium batteries do not produce any pollutants during the production and use process, ensuring human health. Therefore, the problem of water and soil pollution in the recycling process of waste batteries can be easily solved.

Lithium iron phosphate battery packaging does not contain any heavy metals and rare metals, non-toxic, no pollution in production and use, in line with European RoHS regulations, is a green battery.

In addition, lithium battery packs also have the advantages of large specific energy, long cycle life, low self-discharge rate, and no memory effect. Lithium batteries have a higher energy storage density, reaching 460-600wh/kg, which is about 6-7 times that of lead-acid batteries. The battery with lithium iron phosphate as the positive electrode has a service life of more than 6 years. It is charged at 1CDOD and used for 10,000 times.

The lithium battery pack for electric vehicles has a high power carrying capacity, which can reach a charge and discharge capacity of 15-30c, which is convenient for high-intensity start-up and acceleration. The self-discharge rate is very low, generally 1%/month, less than 1/20 of Ni-MH battery; Lithium battery can fully meet the needs of automobile power, in addition to its green and environmental protection characteristics, it has become an ideal for electric vehicle applications product.

Are lithium batteries really so environmentally friendly?

From the perspective of the development of new energy vehicles, lithium battery packs are more environmentally friendly, and the development of automotive fuels is accompanied by the development of energy. In the oil age, the use of gasoline and diesel as vehicle fuel will not only cause urban air pollution, but also cause the rise of fuel prices due to the shortage of oil supply, followed by the emergence of natural gas vehicles and biofuels as alternative fuel vehicles. The development of energy will gradually transition to renewable energy. Electric vehicles that use solar energy and wind energy to generate electricity will appear. Finally, new energy vehicles that use power lithium batteries as the main energy storage will appear.

At present, the anode materials of lithium batteries mainly include lithium cobalt oxide, lithium manganate, and lithium iron phosphate, and the anode materials basically include materials such as graphite and lithium titanate. In recent years, with the increasing trend of environmental protection in our daily lives, we have to consider materials from other aspects. Lithium battery packs should gradually begin to artificially manufacture positive and negative materials instead of blindly extracting the required elements from ore, which greatly reduces environmental pollution.
