What are the important differences between lithium ion batteries and lead-acid batteries

Compared with lead-acid batteries, the low-temperature performance and high-current performance of lithium-ion batteries are weaker, which is absolutely unlucky for the start-up power supply. The discharge function of lead-acid batteries can cope with more severe conditions, and lithium-ion batteries cannot be used in low-temperature areas. In addition to low temperatures, in summer exposure conditions, mobilizing the high temperature of 60 to 70 degrees in the cabin can also make lithium electronics scrapped. In terms of high-current performance, most of the instantaneous current when the car starts is more than 200A, and the performance of the lithium-ion battery will drop rapidly under high magnification. 2. Skill cost is a decisive factor for promotion. Lead-acid batteries are cheaper than lithium-ion batteries. With the same capacity, lead-acid battery technology has matured, and the electrode material, electrolyte, assembly conditions are low, and even the cost is low. The lithium-ion battery process is huge, and dust-proof requirements, relative humidity, and accuracy must be controlled. More than 3 times more expensive than lead-acid batteries. 3. The momentary heat released by the power supply at a peaceful level puts the car in a dangerous field. It is also mentioned in the battery function that lithium-ion batteries are easily scrapped and ignited at high temperatures. Lead-acid batteries have good high-current performance, and their materials are not flammable when they are dangerous. Lithium-ion batteries use graphite as a raw material, so the flammability must be high. 4. Battery life If the lithium-ion battery can safely escape the high temperature in summer and low temperature in winter, but if you want to use the car often, the lithium-ion battery will passively stay in a fully charged state for a long time. The lithium-ion battery itself is not suitable for being in a fully charged state for a long time, otherwise it will affect the battery life. Today we will pay attention to the upcoming changes in the battery industry. At present, there are about 200 million electric bicycles in my country, 90% of which use lead-acid batteries. However, the new national standard stipulates that the weight limit of the vehicle body is within 55kg, which makes the shortcomings of the heavy weight of lead-acid batteries more prominent. At the same time, the new national standard encourages the initiation of replacement of lithium-ion batteries, and this year, the battery industry has been spreading that lead-acid battery companies will be cut and that lithium-ion batteries will usher in a big outbreak.
