R6 Carbon battery

Discussion on the requirements for the classification and development of R6 Carbon battery

The price of lithium batteries is mainly composed of three major components: battery cells, protection boards, and shells. At the same time, due to the power consumption and current of the electrical appliances, the selection of materials for the connecting sheets between the battery cells (conventional nickel sheets, molded nickel sheets, copper-nickel composite sheets, jumper sheets, etc.) will affect the cost. Different connectors (such as special plugs, ranging from a dozen yuan to thousands of yuan) may also have a greater impact on the cost. In addition, different PACK processes will also affect the cost.

The current main market for lithium batteries is the application of portable terminal devices, which has made high capacity the main direction of lithium battery development for a time, but in the context of the full development of electric vehicles and large-scale power storage equipment, the main direction of lithium-ion battery research and development has also shown 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 and used for a long time.

The development of rechargeable batteries for portable terminals is oriented towards high capacity. For this reason, high capacity must be achieved even at the expense of life, and the requirement for life is generally about 2 years. After the advent of the electric vehicle era, the direction of lithium-ion battery research and development has changed. Now electric vehicles mainly include three types: hybrid vehicles, plug-in hybrid vehicles and pure electric vehicles.

For hybrid vehicles, large power exchange is required during acceleration and deceleration, so high-power batteries are more ideal.

On the contrary, pure electric vehicles require more large-capacity support because they only rely on power lithium battery packs to provide electricity, and plug-in hybrid vehicles are between the two. So it can be concluded that in terms of high-power lithium battery requirements, hybrid vehicles> plug-in hybrid vehicles> pure electric vehicles; and in terms of large-capacity lithium battery requirements, it is just the opposite, pure electric vehicles> plug-in hybrid vehicles> hybrid vehicles.

Of course, this is a comparison within different electric vehicles. On the whole, the requirements for capacity and power of lithium batteries for electric vehicles are several times higher than those for portable terminals, and they also require higher life and safety. Otherwise, they cannot enter the industrialization stage.

The performance requirements of large-scale energy storage facilities for fixed installations are also several times higher than those of electric vehicles. From the perspective of safety alone, for building storage systems and household storage systems, they must have "high" safety performance that will not burn in the event of a fire, while lithium batteries for electric vehicles and portable terminals obviously do not have this requirement. Different main demands can also be divided within energy storage facilities for fixed installations.

For peak-period conversion for nighttime storage and daytime discharge, the battery is required to have a large capacity, such as lithium batteries for energy storage facilities for 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 able to solve the fundamental problems, so lithium-ion capacitors that combine the advantages of lithium-ion batteries and traditional double-layer capacitors have emerged, and new technologies for developing new redox flow batteries are also in the simultaneous research and development stage.
