characteristics of lithium-ion batteries and lead-carbon batteries

　　Lead-carbon batteries have the following characteristics

　　1. The operating temperature of lead-carbon batteries ranges from -23 ° C to 60 ° C

　　2, lead carbon battery discharge depth of 60%, can be recycled for more than 3000 times (the test is not terminated)

　　3, lead carbon battery added carbon, carbon has good thermal conductivity, so lead carbon battery is suitable for high temperature work

　　4. Most lead-carbon batteries are front-end or horizontal. Batteries are wired at the front for easy maintenance. There is no maintenance space between the battery layers, which greatly saves the installation area

　　5. The low temperature discharge performance of lead-carbon battery is higher than that of traditional lead-acid battery. The discharge capacity of conventional lead-acid battery is only 50% at -20℃, while the discharge capacity of lead-carbon battery is 66% at the same temperature. Lead-carbon battery (PSoC) in partially charged state can inhibit the occurrence of negative sulfate, and the battery will not fail due to insufficient charge. (Sulfate crystallization on the negative electrode is one of the causes of failure in common valve-controlled lead-acid batteries.)

　　6, the traditional lead-acid battery can only be charged in the maximum 0.2C (standard electricity is 0.1C). Lead-carbon batteries can accept a maximum charge of 0.6c (standard charge is 0.3C), and the charging current is three times that of traditional lead-acid batteries, which can greatly shorten the charging time, especially suitable for unstable charging solar systems.

　　Second, the characteristics of lithium-ion batteries

　　1, low self-discharge rate, no memory effect

　　2, lithium ion battery has strong adaptability to high and low temperature, can be used in -20℃-60℃. After processing, it can be used at -45℃

　　3, with high power carrying capacity, electric vehicle lithium iron phosphate lithium ion battery can reach 15-30c charge and discharge capacity, convenient for high-intensity start and acceleration

　　4, lithium ion battery high voltage platform: the average voltage of a single battery is 3.7V or 3.2V, about equal to the series voltage of three nickel-cadmium batteries or nickel-metal hydride batteries, easy to form a battery power group

　　5, lithium ion battery has a long service life, the service life can reach more than 6 years. The battery with lithium ferrous phosphate as the positive electrode is charged and discharged with 1cdod, which can be used 1000 times.
