Lithium batteries, lead-acid batteries in the future will be a fierce battle in the field of electric vehicles

In the lithium battery And lead-acid storage The battery The properties of the contrast, the two different types of cells each has its advantages. Lead-acid battery is the biggest advantage of applicable temperature zone is very wide. Discharge function in low temperature environment is good, the ontology not an explosion in high temperature environment, safety performance is high. It's another big advantage is the lower price, thanks to its rich resources of raw materials and high cycle rates. In contrast, lithium battery, its advantage lies in the battery energy density is high, it can make it need high range field of new energy vehicles open markets.

Lithium batteries, lead-acid battery application field contrast between the future will 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 popular in many application fields. Lithium battery, on the other hand, are the characteristics of lightweight portable let it occupy the mobile phone batteries and laptop batteries and other small battery market. Lithium battery and lead acid storage battery in the future will encounter areas will be market of electric bicycle and electric car market. At present, the electric bicycle market, lead-acid battery accounted for 95% of the market. In the field of new energy vehicles, because the latest TuiPo subsidies policy implementation, puts forward higher requirements on energy density of battery, it also promoted the lithium battery with high energy density in the industry development.

"Lithium" policy bring vitality to the development of lithium battery industry

At the end of 2017, the electric moped battery, part 1 technical conditions ", "electric power battery part 2, the product specifications, release, and in July 1, 2018 formally implemented. Battery new GB have specific provision, the energy density of batteries battery lightweight set the standard, such as the new standard explicitly pointed out that the quality of electric vehicle includes a battery shall not be greater than 55 kg, the rigid requirements means that a lot of lead-acid battery will be eliminated, but also means that the lightweight portable lithium-ion batteries will usher in the development of the spring.

Another "four-wheel electric vehicle technology at low speed conditions (draft)" also issued, according to the known as environmental protection, power battery products can only be used in the draft requirement Power lithium battery. If the draft fall to the ground, Lithium ion batteries Will be under the guidance of national policy to accelerate the development of lead-acid battery at the same time will lose opportunities in this area.

Recycling technology for short periods of time can't breakthrough allows businesses to the production and recovery of lithium ion

In front of the country has no battery new gb, lead-acid battery in the secondary market power is invincible, the biggest regards is cheap. Relative to lithium batteries, lead-acid battery production process is very simple, don't need to have special production control, purchasing production machines and environmental purification, can be put into production; Lithium battery, on the other hand, the production process needs to be very precise production conditions, realize the precise production condition is the premise of a large amount of upfront capital investment, it also bring huge cost to the production of lithium battery.

But lithium electronic real businesses, is the recycling process of the complex. Lithium battery recycling must be pretreatment in the first place, this link process is various, and the battery only can be recycled plastic and metal shell, after dismantling of the high cost of recycling in terms of pre-treatment, is financed; After preprocessing is to extract the anode electrode, mixture ratio is very tricky, has cost a lot, and after the extraction liquid waste processing process of heavy, high cost, let off lithium electronic recycling for domestic enterprises.

In contrast, lead-acid batteries, because the battery in the lead, molded case, partition, all of sulfuric acid can be recycled, so waste lead-acid battery is a very valuable thing. And recycling technology of waste lead acid battery is more simple, the recycling of waste lead acid battery is "money" in recycling, 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.
