The process of assembling lithium battery cells into groups is called PACK, and it can be a single battery or a series or parallel battery module Under the background of the new national standard, the demand for lithium batteries is increasing, and many lead-acid battery companies have also introduced lithium-ion products.

The so-called lithium iron phosphate battery refers to the lithium ion battery with lithium iron phosphate as the positive electrode material When it comes to lithium iron phosphate batteries, what you see is a series of reliable words such as environmental protection, safety and large capacity.

The expansion of the lithium battery is normal, indicating that the lithium battery is aging and does not store electricity This is normal and there is no safety hazard.

Currently, there are two mainstream designs for the batteries of electric cars One is represented by Tesla, which adopts the battery management system of ternary lithium battery and high IQ ,it is used to give full play to the advantages of large energy density of ternary lithium battery.

"The Tesla battery factory had a faulty manufacturing process and some of the damaged batteries were installed in the car, which musk ignored"Tripp, a former Tesla engineer who was at the center of the Tesla scandal two months ago, took to social media today to expose evidence of flawed manufacturing practices at the company's battery plant.

From mobile MP3 players to electric cars, making rechargeable batteries that are safer, last longer and have more cycles has been a key technical challenge The lithium ion battery technology we have used for many years has many obvious disadvantages, such as fast battery degradation, short life, not environmental protection, and so on.

A few days ago, foreign media published a news one after another, electric car brand Fisker applied for a patent of a solid lithium battery, which has the highest range of 800 kilometers, charging only for one minute Everyone is boiling up, because it is a solution for the two major problems of battery life and fast charge.

The lithium battery is unlike previous Ni-Mh battery activation Lithium battery can be used normally after it is full of electricity.

Most people will certainly be more concerned about the price as well as battery, the most important parts of the electric car, before they buy a car The battery is available in the market of two kinds: lead-acid batteries and lithium battery, which also largely determines the overall price.

1, Nickel metal hydride battery develops early, is already very mature, but its technology seems a bit backward at present The biggest disadvantage is that it has the memory effect, which influences the usage and sustainability;2, the lithium battery development relatively late, but technology developing rapidly, at present most of the research is focused on lithium battery technology, the biggest advantage is no memory effect, and defect is lithium battery cost is relatively high.
