The outstanding performance of lithium batteries: Why They have Become the "darlings" of Modern Energy

In the arena of energy technology, lithium batteries have stood out with multiple core advantages. With an energy density of up to 200-300 Wh/kg, it is several times higher than that of traditional lead-acid batteries, enabling mobile phones and electric vehicles to achieve lightweight design. The extremely low self-discharge rate (about 5-10% per month) enables the backup power supply to remain on standby for a long time. In terms of cycle life, mainstream lithium batteries can still retain over 80% of their capacity after 1,000 charge and discharge cycles, far exceeding the performance of nickel-metal-hydride batteries. What is more worth mentioning is that the working voltage of lithium batteries at 3.7V is three times that of nickel-cadmium batteries, simplifying the circuit design. The feature of no memory effect has completely changed users' usage habits. There is no need to deliberately "drain the battery"; charging at any time can maintain the best performance. These outstanding performances make it an irreplaceable energy choice in fields such as consumer electronics and new energy vehicles.
