Our company has produced a lot of battery every year, the high temperature resistance car 18650 battery, cylindrical battery, 1500mAh Li-ion cylindrical battery are our hot sale products. The capacity of high temperature resistance car 18650 battery with large capacity is generally between 1200 MAH and 3600 MAH, while that of general battery is only about 800. if combined 18650 lithium battery to 18650 lithium battery pack, the 18650 lithium battery pack is casually can break through 5000mah. Now let me tell you the advantages are as follow: Long life 18650 lithium battery has a long service life, the cycle life can reach more than 500 times during normal use, which is more than twice that of ordinary batteries. high safety performance 18650 lithium battery has high safety performance, does not explode, does not burn; Non-toxic, pollution-free, ROHS trademark certification; All kinds of safety performance can be completed at one time, and the cycle times are more than 500 times.
High temperature resistance 18650 battery, discharge efficiency up to 100% at 65 degrees. In order to prevent the short circuit of the battery, the anode and cathode of 18650 lithium battery are separated. Therefore, the possibility of short circuit has been reduced to the extreme. A protective plate can be additionally arranged to avoid overcharging and over discharging of the battery, thus prolonging the service life of the battery. The voltage of 18650 lithium batteries with high voltage is generally 3.6V, 3.8V and 4.2V, which is much higher than the voltage of 1.2V of nickel cadmium and nickel hydrogen batteries. Without memory effect, it is not necessary to empty the remaining power before charging, which is convenient to use. Low internal resistance: The internal resistance of polymer battery cells is lower than that of ordinary liquid battery cells. The internal resistance of domestic polymer battery cells can even be below 35mΩ, which greatly reduces the battery's power consumption, prolongs the standby time of mobile phones, and can completely reach the level of international standards. This kind of polymer lithium battery, which supports large discharge current, is an ideal choice for remote control model and is the most promising product to replace nickel-hydrogen battery.
Cylindrical battery is divided into different systems of lithium iron phosphate, lithium cobaltate, lithium manganate, cobalt manganese mixture and ternary materials. The outer shell is divided into two types of steel shell and polymer. The batteries with different material systems have different advantages. At present, the cylinder is mainly made up of cylindrical lithium iron phosphate batteries with steel shells. Lithium iron batteries are characterized by high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, capability of large current discharge, electrochemical stability, safety in use (no combustion or explosion due to improper operation such as overcharge, over discharge and short circuit), wide operating temperature range and environmental friendliness. Widely used in solar lamps, lawn lamps, backup energy, electric tools, toy models.
