In today’s era of rapid technological development, battery technology, as the core support for numerous fields, attracts much attention with every breakthrough. Recently, long – cycle batteries have become the focus of the industry due to a series of excellent performances, and are expected to open a new chapter in battery technology.
Long – cycle batteries have significant performance advantages. They adopt the lithium iron phosphate system, which endows the batteries with extremely good safety and reduces the possibility of danger during battery use from the source. In terms of energy density, it can reach ≥ 180Wh/kg, meeting the high – energy storage requirements of various devices. Meanwhile, it supports a 15C instantaneous discharge current, which means that long – cycle batteries can perform well in scenarios requiring instant high – current output. More notably, its 0.3C charge – discharge cycle life exceeds 15,000 times, greatly reducing the periodic use cost and significantly improving the cost – effectiveness of the batteries.
In the safety test, the performance of long – cycle cells is remarkable. Taking the lithium iron phosphate – 206Ah cell as an example, in the bullet – shooting battery safety test, after a Type 95 rifle bullet penetrates the cell at a speed of 930m/s and an muzzle energy of 1952J, the battery only smokes, without fire or explosion. The voltage gradually drops to 0V, while the internal structure and pole connections of the battery are intact and there is no obvious deformation. In addition, it has undergone a number of extreme tests such as thermal runaway, overcharging, extrusion, short – circuit, and heating, and has successfully passed all of them, and has obtained many domestic and international authoritative certifications such as GB, IEC, and UL, fully demonstrating its stability and reliability under various complex working conditions.
The emergence of long – cycle batteries has far – reaching significance for industries such as new energy vehicles and energy storage. In the new energy vehicle field, its long cycle life can reduce the battery replacement frequency and lower the user’s cost; high safety provides more reliable protection for drivers and passengers; and high energy density and high – current discharge capacity can improve the vehicle’s driving range and power performance. For the energy storage industry, long – cycle batteries can effectively improve the stability and service life of energy storage systems, promote the large – scale storage and utilization of renewable energy, and contribute to the optimization and upgrading of the energy structure.
Looking to the future, with the continuous improvement and large – scale application of long – cycle battery technology, it will inject strong impetus into the global energy transition and sustainable development. It is believed that in the near future, long – cycle batteries will become the preferred power source for more fields, promoting the development of various industries in a more efficient, safe, and environmentally friendly direction.
