What is the important difference between lithium-ion batteries and lead-acid batteries?

1. First of all, in terms of the raw materials for the production of batteries and lithium-ion batteries, the materials used are different. The electrodes used in lead-acid batteries are lead plates, and the electrolyte is inorganic sulfate, which is liquid or colloidal, and lithium-ion batteries are used. It is a lithium alloy, and the electrolyte is mostly organic electrolyte, which is solid, liquid and colloidal. 2. Comparison of battery life and lithium-ion battery life: Lead-acid batteries generally have a memory effect within 300 times of deep charge and deep discharge, and their life span is about two years. And there is acid salt liquid in the lead-acid battery. After a period of consumption, the battery will become hot or the charging time becomes shorter, so you need to replenish the liquid; the lithium ion battery has strong durability, slow consumption, more than 500 times of charging and discharging, and no memory. The general life span is 45 years; 3. Comparison of storage batteries and lithium-ion batteries in terms of volume and quality: Generally, the weight of a single lead-acid battery is 1630 kg, which is relatively large; the lithium-ion battery is generally 2.53 kg, which is relatively small; also That is to say, under the same capacity and power consumption, lithium-ion batteries are much smaller in weight and volume than lead-acid batteries; 4. Comparison of battery and lithium-ion batteries in terms of price and warranty period: the current mainstream battery voltage on the market is 48 volts , Mostly used in electric vehicles, if it is replaced with the same capacity, the lead-acid battery is about 500 yuan, and the warranty period is 1 year; the price of lithium ion batteries is relatively expensive, about 1,000 yuan, but the warranty period is two years; 5. Comparison of battery and lithium-ion batteries in terms of environmental protection: lead-acid batteries are polluted during the production process. If improper recycling can cause pollution and endanger human health; lithium-ion batteries are relatively green and environmentally friendly and have relatively little harm to the environment.
