Advantages:1 Long life2 Low price3 can discharge large currentDisadvantages:1 Lead pollution2 Low energy density, that is, too heavyAdvantages and disadvantages of lithium-ion batteries and lead-acid batteries for electric vehiclesExcessive life spanThe recycling life of lead-acid batteries is about 200 times, with a maximum of 300 times The recycling life of lithium-ion batteries has reached more than 300 times, and standard charging(5 hours rate) can be used up to 500 times or even more than 1,000 times.

After a period of fermentation and dissemination, Samsung's note 7 battery explosion has developed from technology news to social news, not only affecting the entire battery industry's nerves, mobile phone consumers have also begun to worry about mobile phone safety So would it be better if Samsung were to switch to all-solid batteries? Because all-solid batteries have a prominent advantage, the safety is much higher than that of liquid lithium batteries and it is not easy to explode.

Due to the good Ionic conductivity and electrochemical stability, lithium hexafluorophosphate has become the core material for the production of lithium cell electrolytes Starting from the second half of 2015, benefiting from the rapid growth of the domestic new energy automotive industry, the market's demand for electrolytes, one of the four major materials for powered lithium batteries, has soared and driven its price to rise rapidly.

New energy vehicles with lithium batteries as energy storage devices have now become the mainstream of the market However, with the promotion and application of new energy vehicles, the problem of self-combustion of lithium batteries and the safety of car use have become concerns.

On the 16th, Harbin Wanxin Graphite Valley Science and Technology Industrial Park, with a total investment of 1 billion yuan, laid the foundation for the foundation of Harbin Science and Technology Innovation City on the north bank of the Songjiang River At the same time, the first graphene composite conductive fluid project in the Northeast has also been officially launched in Kazakhstan and put into mass production.

Lithium batteries generally have a life span of about 5 to 6 years, and the warranty period is generally about 3 years This is much more than the average battery's life span of only one year or one and a half years, so there is no need to worry about changing the battery every year.

From MP3 phones to electric cars, making batteries that are safer, have a longer life and have more rechargeable cycles has always been a key technical challenge We have used many years of lithium-ion battery technology has many obvious shortcomings, such as fast power degradation, short life, environmental protection, etc.

The lead-acid battery is a relatively old battery, has been used for 150 years, the performance is good, but it is difficult to support large current deep discharge;Lead-carbon battery is a new type of super battery You can understand it as follows: lead-acid battery and supercapacitor are integrated into a lead-carbon battery.

To detect the empty voltage and load voltage of the battery, the good battery is about 13V empty, and the load is 8-9V The bad battery load voltage will be very low.

The power cell is the core of the development of new energy vehicles Today, the new energy automotive industry is booming.
