Scientific research is sometimes very simple, not as deep as you think What scientists need to do is to find the real academic problems from daily life and 'poke through the window', so as to open a window and see the further scenery.

In order to strengthen the management of the lithium-ion battery industry, standardize the industrial development order, and guide the continuous and healthy development of the lithium-ion battery industry, the Ministry of Industry and Information Technology issued the "Specification Conditions for the Lithium-ion Battery Industry"(hereinafter referred to as the specification conditions) on the official website on December 12 to the public For opinions, the deadline is December 20, 2014.

"Green complex" is the keyword that Zhangtianren, who was elected to the National People's Congress for the second time, described himself As the founder and chairman of the new energy power battery company, Zhangtianren has always regarded "green and environmental protection" as the starting point for corporate development.

"The implementation of the 'double points' management method is about to be implemented The new energy automotive industry is facing problems such as rapid expansion of production capacity, shortage of industrial chains, and lagging recovery and utilization.

With the continuous maturation of science and technology, more and more new technologies and equipment have been applied to the market As far as the battery market is concerned, the emergence of lithium batteries has solved the problems of short life, incomplete charge and discharge, memory effects, and heavy metal pollution of traditional lead-acid batteries.

Lithium batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries The electrolyte of a lithium-ion battery is fluid, so it is more unstable than a Lithium-Polymer battery, hitting an external force, or using a non-standard charger can cause the battery to explode.

As a result of the popularity of lithium battery, a lot of electric cars on the market use lithium battery now, this also makes the accident that lithium battery explosion causes casualty to happen from time to time, the cause of the explosion of the lithium battery is popularized today First, the lithium battery negative capacity is insufficient When the capacity of the negative electrode portion of the positive electrode portion of the lithium battery is insufficient, lithium atoms generated during charging cannot be inserted into the interlayer structure of the negative electrode graphite, and are deposited on the surface of the negative electrode to form crystals.

"How should the power battery develop? In fact, it is closely related to how electric cars develop What kind of battery develops what kind of electric car, not beyond the battery level to dream up the electric car target.
