China New Energy Car Brought about by the wave of enthusiasm, is to have the mobile Communicate And mobile audio-visual aspects of a great convenience of lithium Battery Become the most popular one of competition and concerns.
However, when more people in life mileage, battery life and even how to deal with other aspects of used batteries brains, a very important fundamental problem seems to be ignored, that is?? It enough security?
1978 3 months, worked at Exxon Oil The company's chemists (engineer) Stanley? Weitinghanmu invention of lithium, probably did not expect the next 30 years, the invention of technology to human life is changing dramatically, and lithium, the nature of known the lightest metal from becoming more intimate and human together.
Time, Weitinghanmu sulfur compounds to make titanium anode, lithium metal as cathode, made of the world's first prototype of a lithium battery.
It works through the lithium-ion battery positive and negative movement between the current cycle in order to achieve the charge and discharge process. Therefore, it is called lithium ion batteries.
Decades, through continuous improvement of the anode and cathode materials, smaller, more and cheaper energy density lithium-ion batteries were manufactured, the advent of mobile phones, further miniaturization and light weight of its and later spread on micro- Electronic Products, such as music players, today is even considered as a wave of strong Electric Vehicles Natural choice.
However, in recent years, cell phones and music players frequent the explosion seems to be the alarm?? This brings convenience to people's lives, things do not seem to think of as safe. Is a manufacturer of quality management was relaxed? R & D are some elements of the battery was changed? Or are they seriously underestimate the storage capacity and security?
A cell phone lithium battery contains lithium metal less than 5g, a most original electric mini-cars, electric 30kwh if storage for more than its lithium battery contains about 50kg of metal around, cell phone battery will be very scared of the explosion is still a Group mini-cars in case the battery in the event, the consequences would be unimaginable.
China has occurred in the lithium battery installed Electric cars Vehicles on, the park in the garage at night suddenly caught fire, together with the vehicle reduced to ashes along with the situation, a few months ago there have been spontaneous combustion phenomenon of hybrid buses, only to find and dispose of early and great harm was not stuffed. Obviously, contingency planning, is the battery, electric vehicle industry responsibility.
In fact, the lithium battery explosion safety hazards exist, many reasons to be cracked, it is clear that all the elements of their own can not get away.
Usually a lithium battery cathode, anode, separator, electrolyte, monomer packing five major elements. At that time, Sony developed the first commercial lithium batteries, the cathode of lithium compounds from the lithium cobalt oxide is made, but because of cobalt are rare, then use more of manganese, iron, vanadium, nickel and polymer composite materials, even the air as the electrode medium, different cathode materials, energy, security, varying voltage.
