The reason why lithium-ion batteries have become the mainstream in the battery market is inseparable from their own advantages. In particular, the development of lithium phosphate battery materials has further promoted the development and application of lithium-ion batteries. The rapid development of the smart electronic product industry in recent years has also provided a significant boost to the development of lithium-ion batteries. Below, I will list the advantages of lithium-ion batteries in detail.
1. High energy
Among all types of batteries, lithium-ion batteries have a relatively high energy density. Lithium-ion batteries have a high energy density, and the specific energy of lithium-ion batteries on the market can reach 460-600Wh/kg, which is almost 6 to 7 times that of ordinary lead-acid batteries, making them more practical.
2. Lighter and more portable
While the battery requirements vary across industries, lightweight, convenient, and space-saving batteries are consistently more popular. This is a key reason why lithium-ion batteries have become the mainstay of mobile electronic devices. In particular, lithium-ion batteries are significantly lighter than lead-acid batteries; a lead-acid battery of the same volume weighs approximately five to six times more than a lithium-ion battery, and its capacity is also smaller.
3. Longer service life
Lithium-ion batteries generally have a longer lifespan, especially those using ferrous phosphate as the positive electrode. The average lifespan of lithium-ion batteries is longer than that of lead-acid batteries, typically exceeding six years.
4. Low self-discharge rate
Lithium-ion batteries have a low self-discharge rate, which is even lower than that of nickel-metal hydride batteries. Therefore, they are unlikely to lose power even when not in use for a long time, and their self-discharge effect is almost negligible. They have a great advantage over both nickel-metal hydride and lead-acid batteries.
