26650 lithium battery, refers to the battery diameter of 26mm, the length of 65mm, cylinder-type battery (pictured). Generally used to call lithium batteries, including lithium primary battery and lithium-ion battery. Commonly useful nickel-cobalt-manganese cathode material, lithium iron phosphate material made of lithium battery - INR26650-3.6V-4500mAh, IFR26650-3.2V-3200mAh.
26650 lithium battery, is mainly used to replace the traditional nickel-chromium, nickel-metal hydride batteries for miner's lamp, flashlight, power tools, toys, instrumentation, ups back power, communications equipment, medical equipment and military lighting and other fields. Its advantages, relative to nickel-chromium, nickel-metal hydride batteries, mainly in the following areas:
1, high energy density, low self-discharge
26650 lithium battery capacity is the same quality nickel-metal hydride batteries 1.5 - 2 times the same time, the domestic 26650 lithium battery internal resistance is less than 60mΩ, greatly reducing the battery self-consumption, prolonging the use of time at the same time to extend the battery Of the service life.
2, charge and discharge performance and stability
26650 lithium battery
no memory effect, the case of heat does not break down, high-performance safety, long life cycle.
3, high voltage
26650 lithium battery voltage is generally more than 3.6,3.7V, much higher than nickel-chromium, nickel-metal hydride batteries.
4, can be used in series or parallel combination 18650 lithium battery pack
5, environmental pollution
26650 lithium battery
is able to charge and discharge, is with the cathode on the active lithium-ion movement and carried out. That is: when the battery is charged, the positive electrode of the lithium battery has active lithium ions generated, moved to the negative electrode, embedded in the negative layer structure. Negative electrode material system is graphite, is a layered structure of carbon, it has many pores, when the lithium ion to the negative pole, it will be embedded in micropores, micro-holes embedded in the more lithium-ion, the higher the charge capacity.
