Lithium batteries are more environmentally friendly than lead batteries?

Lead acid batteries are widely used in many fields of national economy as storage equipment with high safety, low price and high recycling efficiency. In detail, the current primary use of lead batteries, one is as a power battery, is currently more used in automotive and electric bicycles; The second is as a backup and energy storage rechargeable battery, which is used in communications, data centers, power, and other occupations that have a high need for uninterrupted power supply or smooth current.

As an environmentally friendly means of transportation, electric bicycles have gained a lot of coverage in China because of their zero pollution, speed and economy in their use. By 2011, the number of electric bikes in China will exceed 130 million, according to Forster Sullivan's calculations. In the meantime, electric bicycles powered by lead-acid batteries account for about 95 % of the number of electric bicycles in shopping malls.

In the lead acid battery company under severe finishing together, relying on excellent functions and the gradual decline of the offer, lithium battery to lead acid battery in place of the supply of all the silent promotion.

"Lead acid batteries and lithium batteries are good and bad, lead acid battery skills are compared with sophisticated, commodity prices are lower, but the energy is smaller, the volume is larger, and the short life span needs to be changed regularly." Chenyungui, a professor of information at Sichuan University, previously received an interview with reporters. According to the report, The lithium battery can be rapidly charged, can discharge high power, small size, long cycle life, but its higher price, and the poor safety function brought about by the skills are limiting the current lithium battery development.

Lithium batteries are far better than lead batteries in environmental protection. However, the skill threshold for lithium battery occupations needs to be higher and attributed to capital-intensive occupations. As a result, lithium battery commodity prices have always been higher and it is not easy to enter shopping malls.

In addition, the safety of lithium batteries due to poor skills has also been questioned.

Liu Xiao showed that the lithium iron phosphate battery skills are now very sophisticated, have a good electrochemical function, the charging and discharging path is stable, and the layout of the charging and discharging process is stable. It has now passed various types of touching, piercing, kneading, overcharging, and short-circuit tests.. During this period, some export company products can reach the world battery specifications such as IEC / UN/UL. In addition, the new skill "Nanophosphate" developed by A123, which is fine, thin, and large in space, will not be heated too quickly in an instant, and it can certainly improve battery integrity.

Liu Xiao believes that with the continuous improvement of skills, the function of lithium batteries is also being rapidly promoted, especially the birth and improvement of lithium iron phosphate batteries, which has enabled the application of lithium ion batteries to be rapidly expanded. "Skill safety can not now be described as the primary impediment to the immersion of lithium batteries into the use of conventional lead-acid batteries. 12V lead-acid battery charger

The poor sale of electric and hybrid vehicles has led to too many competitors in the small battery market. Capacity and shopping malls need to be more severe. It's kind of like an unbreakable vicious circle: electric car stores are slow to roll out -- partly because the price is too high, and the main reason for the high price is because of expensive batteries -- the cost is at least 10,000 US dollars; But on the other hand, if the market needs not, the battery's capacity will not go up, and the cost of the battery will naturally not come down. Moreover, such a situation will not substantially improve in the short term.

"Although it is impossible to replace lead-acid batteries with lithium batteries in the short term, and the skill stability of lithium batteries needs to be further developed, the market burst period for lithium battery bicycles may be in the past few years. "Mazhongchao, chairman of the China Bicycle Association, once stated that vigorously promoting the development of lithium battery bicycles is one of the important tasks of the association.

E-bike battery replacement secondary shopping malls, the occupational concentration effect will grow faster. In recent years, the new purchase of electric bicycle shopping malls needs to slow down. By 2011, secondary shopping malls accounted for nearly 60 % of the total bicycle power of China's 18650 battery shopping malls. In the past, many small and medium-sized companies still accounted for a large share of shopping malls in regional secondary shopping malls because of the relatively fragmented approach of secondary shopping malls. However, the decline of small and medium-sized companies in commodity development skills and production capacity will make these companies greatly affected in the implementation of the "access conditions" and are more likely to face the fate of shrinking market shares in the process of changing the professional format.
