How do lithium-ion battery stores usually choose lithium-ion batteries? Nowadays, it is easy for manufacturers and designers to think when choosing batteries for new products, but they lack a deep understanding of how to choose the appropriate battery. How to choose the performance of lithium-ion batteries. Lithium ion batteries have high internal resistance because the electrolyte inside the battery is gel rather than aqueous solution. In addition, electrode materials with extremely low water content and stable physical and chemical properties also allow lithium-ion batteries to operate safely over a wide temperature range. A single lithium-ion battery can operate at low temperatures of -55 ℃ and high temperatures of+150 ℃. The rated output voltage of lithium-ion batteries is 2.7-3.6V.

Electrode materials for lithium-ion batteries

Different electrode materials endow lithium-ion batteries with different characteristics, which are important in the following aspects:

● Rated voltage, minimum voltage, maximum voltage;

● Initial discharge current, average discharge current, maximum discharge current;

● Continuous discharge performance and intermittent discharge performance;

● Voltage fluctuations and discharge time (non continuous) when connecting the minimum and maximum loads; Low service life;

● Environmental temperature range;

● Maximum discharge current at the lowest operating temperature;

The minimum time for the voltage to rise to the lower limit value;

● Storage time and conditions;

In general, devices that require short-term high current power supply have relatively low sustained power supply capacity (some even do not), but their short-term power supply demand is often a few amperes, with a duration ranging from a few seconds to 20 minutes. They chose instruments that require a battery life of up to 20 years under harsh conditions.

Lithium ion battery storage reminder: The selection of lithium-ion batteries should be based on the usage scenarios of lithium-ion batteries used in electronic devices or new energy vehicles. Of course, the technical strength of lithium-ion battery manufacturers, lithium-ion battery lifespan, safety indicators, price, and other factors should also be considered in the selection of indicators.
