What are the advantages and disadvantages of lithium battery and lead-acid battery in electric vehicle?

If the condition permits, lithium electricity is better.

1, lithium battery, light weight, average 4 kg, general girl can carry away very easily; Lead-acid battery is a set of general 17 kg, big man upstairs dead-beat also there.

2, lithium battery charge and discharge times of up to 1200 times, available about 3-5 years; Lead acid battery charge and discharge times to 300 times or so, only can use 1 to 2 years.

3, lithium traction motor for high speed toothed commonly, itself has a one-way guiding role, much like a flywheel, no electricity is like riding a bicycle as easily; Lead-acid electric motor is generally low speed with no teeth, no electricity, people should overcome the resistance of the phase line magnetic field lines when riding, basically it did not move, can only find a car away.

Buy lithium trams key is to see batteries, lithium electricity now whether imported or domestic technology has been very mature, market is rare, because the market purchasing power shortage, is not the manufacturer no seer.

General battery with this end there will be a manufacturer logo, better to have: dual dint, perseverance, Lishen, depressive Weida, Beyma etc, but the price is expensive, with the peace of mind.

The big manufacturers are doing lithium electricity, such as iso9000, Yadi, Emma, island, if you are allowed to buy the more expensive kind of economy, such as giant, good boy.

Among them, the largest number for lead-acid battery. Lead-acid batteries of the lowest price, also the most commonly used, China is the world's lead-acid battery's biggest producer. Its composition containing pollution is less, good recyclability. The disadvantage is that specific volume is small. That is to say, under the same capacity, battery weight and volume is bigger. The lead-acid battery is basically developed by floating type of battery. Floating battery don't adapt to the quick charge and large current discharge, although technical personnel has spent a lot of work to carry on the effective improvement, can enter the practical, but the life is very not ideal.

Classification of gel battery is a kind of lead-acid battery development, the simplest approach, is added in the sulfuric acid gelling agent, sulfuric acid electro-hydraulic colloidal becomes. Electro-hydraulic of colloidal battery often called gel battery. Broadly speaking, the difference between gel battery and conventional lead-acid battery is not just about electro-hydraulic to gel.

Solidification states such as water-based gel, look from electrochemical classification structure and characteristics belong to gel battery. And like a knot in the plate grid with high polymer material, commonly known as the ceramic plate gate, can be regarded as the application characteristics of gel battery. Recent laboratory existing in plate, a targeted coupling agent is added to the formula has greatly increased the plate, the utilization of active substance reacts according to nonpublic information can reach 70 wh/kg weight than energy level, these are the current industry practice and needs to be industrialized application example of gel battery.

The difference between gel battery and conventional lead-acid batteries, from the initial understanding of gel electrolyte, a further development to research infrastructure of electrolyte electrochemical properties, and the application of sheeting and active substances. Its most important characteristic for: use a smaller industrial cost, along the 150 - year history of the lead-acid battery industry way to create more high-quality batteries, its flat discharge curve, inflection point, high specific energy, especially more than 20% higher power than conventional lead-acid batteries, life in general, about twice the length of a conventional lead-acid battery, high temperature and low temperature properties is much better.

Lithium ion batteries

Specific volume of lithium ion batteries are better than Ni-Mh batteries, for the same capacity of lead-acid battery, the weight of the lithium ion battery is equivalent to a laptop computer, so that the old women and children can be used. The life also can do better than Ni-Mh batteries. The current mobile phone batteries are basically use this battery. Lithium battery internal resistance is relatively large, used on electric bikes will be you feel the car battery to completely discharge the power shortage. Lithium ion battery more problem is mainly in explode to over charge and discharge the battery, cell phone batteries are using monomer battery, again after a good protection circuit to cooperate to use, largely free battery explosion problem. And used on electric bikes, must use string battery pack, and the complexity of the string of battery protection circuit much bigger than that of the monomer battery protection circuit, and greatly increase the cost of materials. Currently the cost of a good lithium battery protection circuit close to the cost of the battery, while polymer lithium battery explosion damage is lower than the lithium ion battery, but also there is the possibility of explosion and combustion. This is like the lithium ion battery needs to solve the problem.

Lead-acid battery technology cost is cheap, simple faults charge-discharge life of an average of 300 times to 300 times shorter lifespan, volume weight.

Lithium battery capacity is one of the five lead weight, charge and discharge long life: ternary polymer li-ion battery charge and discharge times, 1000 times the highest electric charging and discharging lithium iron phosphate life over 2000 times. Weakness: the price is high so the penetration rate is less than lead-acid, electric cars and tricycle is 90% with lead-acid batteries.

Lithium ion battery is referred to as the most superior performance rechargeable batteries, has "the ultimate battery," said. Compared with traditional lead-acid battery and nickel metal hydride, nickel cadmium battery, the lithium ion battery of time is very short, its industrialization and market applications so far, only 10 years of time, but it is one of the fastest growing in the rechargeable battery. At present, lithium ion battery is in continuously improve performance, reduce costs, application field rapidly expanding market share, sharply growth stage, and gradually replaced the nickel metal hydride, nickel cadmium rechargeable battery.

With bluetooth, mobile phones, notebook computers, camcorders, digital cameras, MP3, MP4, PDA and electric tools such as consumption and portable electronic products continued to be strong, the lithium ion battery market demand has remained high growth rate, market, the huge demand for lithium ion batteries, and the massive manpower and material resources, financial resources, guide the lithium ion battery industry gradually strengthened, thus promoting the battery cost, material, security, performance, management systems, battery charger and so on various aspects of development, finally make the lithium-ion batteries in electric bicycle and electric vehicle applications possible.

Luyuan store there is a small of lithium battery electric bicycle, weighs only about 16 kilograms, the battery is the size of a book, only 2.5 kg, can carry on bag, can also be used to recharge my computer, while with the horsepower of lead-acid battery weight at about 15 kg. The electric price is more expensive, however, to more than 2800 yuan." This car on the market only a week, the price is higher, but the sales is better than expected, a week will sell several cars."Luyuan ev zhang, director of introduction, this kind of car USES lithium battery, a charge can run 30 km.

It is understood that the current domestic electric bicycle ownership is controlled in 120 million, Tianjin electric bicycle production last year set a new record of 8.28 million vehicles and widely used at present most of the owners of electric vehicle battery is the battery life is short, short battery life and imperfect recovery link problems, especially in can't use after charging, the hidden danger of environmental pollution by waste lead-acid batteries exist but not recycling a formal channels. And has been in this, South Korea and other places are used widely in electric bicycle lithium battery can to a certain extent "embarrassment" of lead-acid batteries. Earlier, according to the introduction of this kind of product of Tianjin gateway power battery technology personnel, the use and laptop batteries, digital products, after a similar principle of lithium battery power battery electric bicycle after each charge mileage and dynamic performance would increase greatly, and because of the characteristic of the lithium battery has no "memory", the service life of the charging will reach more than doubling of lead-acid batteries. With common on the market at present the average price in 300 yuan compared to the ordinary lead-acid batteries, lithium-ion battery power battery although prices have improved, but the comprehensive use of cost can be reduced by 25%.In addition, the lithium battery because there is no pollution of lead and acid solution, also has the recycling convenience, safety and environmental protection features. The personage inside course of study says, the more environmental protection, lightweight, longer service life of electric bicycle "new energy" as prices falling, will quickly gained popularity.
