Electric Vehicle Power UPS Battery Development Prospects

Electric vehicle power UPS Battery development prospects
Many people know that lithium-ion UPS Battery is mainly by the positive, negative, diaphragm and electrolyte of the four main components. Only when the lithium UPS Battery is a strong impact, the electrode over-voltage loss of heat, to promote the solvent and the negative reaction, the heat released by further heating the UPS Battery to promote the thermal decomposition of the positive reaction occurred, resulting in heat out of control. As the heat out of control, the rate of external heat exchange is less than the heat accumulation rate, the temperature continues to rise, directly to the ignition point temperature, causing combustion and explosion.
In the current production process of electric vehicles, electric vehicles used in the UPS Battery mainly includes lithium iron phosphate battery, lithium titanate UPS Battery and three yuan lithium UPS Battery. The famous brand Tesla electric car is mainly used in the three yuan 18650 lithium UPS Battery, and Tesla in the batteries, pack, UPS Battery management system, etc. have done a very complete security design, so Tesla relative to Said the fire accident is not too high. Therefore, the three yuan lithium UPS Battery is slowly becoming the mainstream of the field of long-distance travel.
Three yuan lithium UPS Battery refers to the use of nickel-cobalt-manganese lithium ternary cathode material lithium battery, ternary composite cathode material precursor products, nickel salt, cobalt salt, manganese salt as raw materials, including nickel cobalt manganese The proportion can be adjusted according to actual needs.
However, due to the safety of ternary lithium UPS Battery has always been electric car manufacturers have been worried about the problem, so lithium iron phosphate battery and lithium titanate UPS Battery competitiveness gradually improved.
Lithium iron phosphate battery battery has the advantage of stable safety performance, high temperature performance, light weight, etc., so many electric buses are still equipped with lithium iron phosphate power UPS Battery. But lithium iron phosphate battery is also a defect, such as low temperature performance, the positive material tap density is small. Although the safety is relatively high compared to the ternary UPS Battery, but there are still the risk of fire burning, real life also occurred in a lot of burning examples, such as JAC, BYD and other models, have appeared such accidents.
The next thing to say is the lithium titanate UPS Battery, this UPS Battery because of the low energy density has been the pursuit of longer life time ignored by the enterprise. Until recently, due to the support of Gree Electric Dong Mingzhu, lithium titanate UPS Battery and then slowly in the new energy automotive market hot up. Dong Mingzhu once said that because the safety requirements of electric vehicles is the first, equipped with lithium titanate UPS Battery electric vehicles have not occurred in the fire burning accident, so it will be from the lithium titanate UPS Battery cut into the field of new energy vehicles The
In addition, the three yuan lithium UPS Battery UPS Battery life is about 2000 times the cycle, while the lithium titanate UPS Battery is 30,000 cycles, and lithium titanate UPS Battery also has low temperature performance, support large magnification Charge and discharge characteristics. For those who seek a higher security performance, the mileage is relatively stable electric bus, the lithium titanate UPS Battery advantage may be relative to the other two have obvious advantages, so most of the electric bus to lithium titanate UPS Battery as the main product.
It can be seen, although the lithium titanate battery UPS is ignored by the market for a long time, but the new energy vehicles in recent years there have been more or less the problem, so we are likely to see three yuan lithium UPS batteries, iron phosphate Lithium UPS batteries and other power UPS Battery competition. In the end who will win, the key depends on who's technology and applicability to enhance the faster, more responsive to the development trend of the times.
