What are the future directions of lithium 3400mah 3.7v 18650 battery research and development?
The current main market for lithium batteries lies in the application of portable terminal equipment. This made high capacity once the main direction of lithium battery development. However, in the context of the full development of electric vehicles and large-scale power storage equipment, the main direction of lithium 3400mah 3.7v 18650 battery research and development has also emerged. There is a trend of diversification.
The traditional mobile terminal market, such as mobile phones and laptops, requires high capacity because they often need to be charged once to be used for a long time. The research and development of rechargeable batteries for portable terminals is aimed at high capacity. To this end, high capacity must be achieved even at the expense of life, and the life requirement is generally about 2 years.
With the arrival of the era of electric vehicles, the direction of lithium 3400mah 3.7v 18650 battery research and development has changed. Today's electric vehicles mainly include three types: hybrid vehicles, plug-in hybrid vehicles and pure electric vehicles. Hybrid vehicles require large power exchanges during acceleration and deceleration, so high-power batteries are ideal. On the contrary, pure electric vehicles only rely on power lithium battery packs to provide electrical energy, so they require more large-capacity support, while plug-in hybrid vehicles are somewhere in between. It can be concluded that in terms of high-power lithium battery requirements, hybrid vehicles > plug-in hybrid vehicles > pure electric vehicles; while in terms of large-capacity lithium battery requirements, just the opposite is true, pure electric vehicles > plug-in hybrid vehicles >Hybrid vehicle. Of course, this is a comparison within different electric vehicles. Overall, the capacity and power requirements of lithium batteries for electric vehicles are several times higher than those of portable terminals. They also require higher lifespan and safety. In addition, It cannot enter the industrialization stage.
The performance requirements of large-scale energy storage facilities for fixed installations are several times higher than that of electric vehicles. In terms of safety alone, building power storage systems and household power storage systems must have high performance that will not burn in the event of a fire. Safety performance, while lithium batteries for electric vehicles and portable terminals obviously do not meet this requirement. Different main requirements can also be distinguished within energy storage facilities for fixed installation purposes. For nighttime power storage to be converted into grid power represented by peak periods of daytime discharge, batteries are required to have large capacity, such as lithium batteries for energy storage facilities in building systems. For photovoltaic power generation and wind power generation, high-power batteries with high tolerance to output power changes must be used, because the output power of these two power generation devices varies greatly due to the great influence of natural factors.
With the transition and transformation of lithium batteries to large-scale applications, lithium batteries themselves are no longer capable of solving fundamental problems. Therefore, lithium-ion capacitors that combine the advantages of lithium-ion batteries and traditional double-layer capacitors have emerged, and there are also efforts to develop new redox flow batteries. New technologies are in the simultaneous research and development stage.
