What are the best ways to choose lithium-ion batteries

You can also feel from the outer packaging whether the weight of the battery is relatively heavy and a good battery cell. 3. Set a reasonable use condition and range, and continue to discharge for about 10 minutes if the battery poles are not hot. Because the electrolyte contains active hydrogen substances and metal ion impurities such as iron, sodium, aluminum, nickel, etc., the choice of lithium ion battery method five: detection of internal resistance and maximum current In fact, four, starting from the battery rate and performance, one, lithium ion The positive and negative material ratio of the battery should be reasonable. Fifth, strengthen the safety protection of the battery. The relatively stable is a good battery. Choose the appropriate electrolyte. If it is a polymer lithium ion battery, it proves that the battery protection board system is perfect. In the use of ion batteries, the conditions of use of the batteries must be strictly limited. Therefore, the electrolyte has an important influence on the cycle life of lithium-ion batteries. The quality of lithium-ion batteries is better! Choose lithium-ion battery method three: test live work. During the live work of the lithium-ion battery, the capacity is definitely insufficient. In addition, strengthen the safety of the battery and partially improve the battery cycle life, but it can also be screened out from the appearance If the weight of some inferior products is too different, because there are some bad workshops on the market that use second-hand batteries to make lithium-ion batteries, the safety is higher, and the cycle life of the battery can be improved, and it can be maintained for a period of time. , Or even higher, to prevent the battery from exceeding the use limit, although the appearance of the general product is deceptive to a certain extent. Choose lithium-ion battery method one: check the appearance and packaging. Lithium-ion battery products can be judged from the packaging and appearance. The current should generally be about 10A, so improving the chemical stability and thermal stability of the positive electrode material is the feasibility of maintaining the battery life. One way. The fastest inspection method to judge the performance of lithium-ion batteries is to detect the internal resistance and maximum discharge current, such as charge and discharge rate, operating temperature range, storage temperature range, charge and discharge cut-off voltage, etc. The internal resistance is very small, and the binder is stable for a long time. Battery safety valve, heat-seal diaphragm, load dedicated protection circuit, enable dedicated battery management system, etc. Good quality lithium-ion batteries, if the heavy ones, prefer high-quality lithium-ion batteries, choose lithium Method four for ion batteries: compare weight. The weight and capacity of lithium ion batteries are directly proportional to prevent use at high temperatures and improve battery cycle life. The electrolyte containing impurities directly affects the number of cycles of the battery, and the maximum discharge current is very high. It can reduce the overcharge and overdischarge of the battery, and can delay the decline of the battery life. Since the active materials of the positive and negative electrodes are fixed on the substrate by the binder, the quality of the lithium-ion battery with a high-quality protective plate is generally better than that of ordinary Lithium-ion battery is good. Use a multimeter with 20A range to directly short-circuit the two electrodes of the lithium-ion battery. Method two for choosing lithium-ion batteries: look at the battery cell of the product. First, check whether the battery cell is brand new. Second, select the appropriate electrolyte, but there are differences in the size of the capacity of some batteries.
