Share the difference between lithium batteries and lead-acid batteries for electric vehicles

What are the differences between lithium batteries for electric vehicles and lead-acid batteries? Charging PbO2+Pb+2H2SO4? 2PbSO4+2H2O positive and negative electrolyte discharge positive and negative (1) The structure of the positive plate of the positive plate is that the grid is filled with lead paste, It is an alloy of lead. The main components of the lead paste are α lead dioxide PbO2 and β lead dioxide PbO2 after being formed during processing and after use. (2) Negative plate The structure of the negative plate is also filled with lead paste in the grid. The main component of the lead paste is spongy (fluffy) pure lead Pb after being processed and used. During normal charging and discharging, the materials participating in the electrochemical reaction on the positive and negative plates are collectively referred to as active materials, the positive electrode mainly refers to PbO2 and PbSO4, and the negative electrode mainly refers to pure lead Pb and PbSO4. (3) Separator Separator is an important component of lithium batteries for electric vehicles and is not an active material. The separator itself is a porous insulating material, and the electrolyte can pass through it smoothly. The main purpose of traditional separators is to guard against short-circuiting of the positive and negative plates. Since the appearance of fine glass fiber separators (AGM), the performance of lead-acid batteries has been improved, and they have been widely used to seal valve-controlled batteries. The thin glass fiber separator has the functions of guarding against short-circuiting of the positive and negative plates, absorbing and storing electrolyte, and supplying oxygen channels. (1) Lithium battery: Use metallic lithium as the negative electrode. (2) Lithium battery: use non-aqueous liquid organic electrolyte. (3) Lithium ion polymer battery: use polymer to gel liquid organic solvent, or use all solid electrolyte directly. Lithium batteries generally use graphite-like carbon materials as the negative electrode. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
