Lithium-ion battery has a high energy density, its capacity is 1.5 to 2 times that of a nickel-hydrogen battery of the same weight, and it has a very low self-discharge rate. In addition, lithium-ion batteries have almost no "memory effect" and do not contain toxic substances. These advantages of lithium-ion batteries make it widely used in the field of new energy vehicles.
Lithium-ion batteries and lead-acid batteries are currently the two most widely used batteries. So what is the difference between these two batteries and which one is better? The following will focus on the difference between lithium-ion batteries and lead-acid batteries.
For lithium batteries, our focus is often on capacity and energy density. These data can usually directly reflect the length of the battery's cruising range. But what we should note is that most lithium batteries are the products of electrochemistry. Since they are related to chemistry, their performance has a great relationship with temperature.
