Lithium-ion batteries, lead-acid batteries or in electric vehicles

Comprehensive, because of the high life demand characteristics, lithium battery in the field of application of new energy vehicles, the future development of new energy vehicles and national policy guidance will promote the development of lithium battery industry, however, the lithium battery in the process of production and recycling high costs still cannot ignore, high security and high resource circulation characteristics of lead-acid storage of low cost and more popular with the producing enterprise, so in the future for a long time, before the lithium battery recycling technology no breakthrough, lead-acid battery in the secondary market power is still solid hard to shake.

In the lithium battery and lead acid battery properties contrast, two different types of cells each has its advantages of lead-acid storage battery is the biggest advantage of applicable temperature with wide discharge function in low temperature environment is good, the ontology not an explosion in the environment of high temperature, high safety performance of its another big advantage is the lower price, thanks to its rich resources of raw materials and high cycle rate in contrast, lithium battery, its advantage lies in the battery energy density is high, this can make it needs high range field of new energy vehicles open markets.

Lithium battery lead-acid battery application field contrast between the future to be a fierce battle in the field of electric vehicles.

Lithium battery and lead acid battery different attributes also determines the two have different application areas, lead-acid battery high safety and the characteristics of cheaper, let its in many application fields, the popular and lithium battery characteristics of lightweight portable, let it occupy the mobile phone batteries and laptop batteries and other small battery of lithium battery and lead acid battery in the future will encounter areas will be market of electric bicycle and electric car market At present, lead-acid batteries account for 95% of the market in the electric bicycle market. In the field of new energy vehicles, the implementation of the latest subsidy rebate policy puts forward higher requirements for the energy density of automobile batteries, which also promotes the development of lithium batteries with high energy density in this industry.

Lithium lithium policy development brings vitality to the development of lithium battery industry Electric moped battery.

At the end of 2017, batteries for electric power vehicles, part 1 technical conditions, electric power batteries, part 2, product specifications were issued, and on July 1, 2018, the battery new national standard was formally implemented. The battery energy density has been clearly stipulated, and battery lightweight has been set. Standards, as clearly stated in the new standards, The complete vehicle quality of electric vehicles must not exceed 55KG. This hard requirement means that many lead-acid batteries will be eliminated, and it also means that light and portable lithium batteries will usher in the spring of development.

Another four-wheel low-speed electric vehicle technical conditions (draft) is also released, according to the environmental protection, the draft requires power battery products can only use power lithium battery if the draft implementation, lithium ion battery will accelerate development under the guidance of national policies, and lead acid battery will lose the development opportunity in this field.

The inability to break through the recycling process in a short time has discouraged enterprises from producing and recycling lithium ions.

In the country did not issue a new battery national standard, lead-acid battery in the secondary power market is invincible-the biggest kill is cheap relative to lithium batteries, lead-acid battery production process is very simple, do not need special production environment control, purchase production machines and environmental protection purification machines, can be put into production; Lithium battery is different, the production process requires very precise production conditions, the premise of achieving these precise production conditions is a large amount of upfront investment, which also brings huge costs to the production of lithium battery.

But lithium electronics really put enterprises off, is the complexity of its recycling process first lithium battery recycling must be pretreated, this link of many processes, and after the disassembly of the battery only plastic and metal shell can be recycled, recycling cost is high, as for the pretreatment link, it is a loss of business; After pretreatment, the electrode positive electrode is extracted, and the mixture ratio is very tricky, and the disposal of the waste liquid after extraction also takes a lot of time. The heavy process and high cost make domestic enterprises shrink from recycling lithium electronics.

In contrast, lead-acid batteries, due to lead in the battery plastic shell all clapboard sulfuric acid can be recycled, so waste lead-acid battery is a very valuable things and waste recycling of lead-acid battery technology is more simple, the recycling of waste lead acid battery is in the recovery of money, will settle accounts of companies are more active in the lead-acid battery recycling, further, the circulation of the lead-acid battery production.

In a short period of time, the lithium battery recycling in the pretreatment stage of face still avoid according to law, and the processing of waste liquid is costly, unless the lithium battery recycling can have major technological breakthrough, let the lithium battery recycling profitable, otherwise, battery recycling market remains lead-acid battery market, lithium battery can't really replace lead-acid battery.
