Tags: What is a secondary battery? There are many types of secondary batteries, and new types of batteries with high efficiency and durability are continuously being developed successfully. Secondary batteries mainly refer to batteries that can be recycled and have a certain life cycle. Let's compare the characteristics of various secondary batteries: Primary battery, lead-acid battery, nickel-cadmium, nickel-hydrogen battery, lithium-ion battery, fuel cell performance, moderate performance, moderate performance, high power discharge energy density, high energy density, very high energy density, medium difference, good energy density Poor power, good, poor, poor service life, good, good, good, good, good, poor, poor environmental protection, poor, good, good, technical maturity, good, good, poor, poor advantages, mature technology, high cost performance, smart and portable, excellent cost performance, mature technology, and good safety High rate charge and discharge, mature technology, high rate charge and discharge, mature technology, high energy density, no memory effect, long cycle life, low self-discharge, high energy density, high energy conversion efficiency, and low pollution. From the above table, we can see that nickel is actually Cadmium and nickel-metal hydride batteries are relatively better than lead-acid batteries in terms of efficiency and environmental protection, but what is important is the current economic conditions of our country. The price and cost of nickel-cadmium and nickel-metal hydride batteries are relatively high, and enterprises and ordinary people are unwilling to choose. Compared with lithium-ion batteries and nickel-metal hydride batteries, lead-acid batteries still have good economic efficiency, and can still have better technical competitiveness in many fields, whether it is the full life cycle use cost or the initial input cost. This is not only the case for single cells, if the complexity of the battery management system is taken into account, the mature technology of lead-acid batteries has more cost advantages. So far, there is no secondary battery that can truly replace lead-acid batteries.
An increasing dependence on the use of sealed lead acid battery top lead acid battery manufacturers has made numerous changes in the top lead acid battery manufacturers industry over the past decades.
