Is 18650 Ni-MH battery better or 18650 Li-ion battery?

1. It is widely used in various electronic device technology fields: common in high-end glare flashlights, portable power supplies, wireless network data communicators, electric heating thermal underwear, shoes, handheld instrumentation equipment, handheld lighting fixtures, Handheld copiers, industrial processing equipment, medical equipment, etc. 2. Long cycle life The warranty period of 18650 Ni-MH batteries is quite long, and the cycle life can reach about 500 times in normal use, which is about twice that of normal batteries. 3. High safety performance. Good performance in ultra-high temperature resistance, and the discharge efficiency can reach 100% under the condition of 65 degrees. The possibility of short-circuit phenomenon has been reduced to the perfect extreme, and the outermost layer can also be installed with a protective plate. Disadvantages of 18650 Ni-MH battery 1. Relatively low energy density The specific energy and energy density of 18650 Ni-MH battery still cannot meet the requirements of PHEV and EV; it means that the battery storage capacity of the battery is low, if it does not last long once it is used There will be no electricity, which is worse than 18650 lithium-ion batteries. 2. Compared with lithium-ion batteries, the battery needs to be improved. The rapid development of nickel-hydrogen battery technology and technology is almost mature and perfect, and the space for battery performance improvement and cost reduction is very limited. 3. The cost of raw materials is higher. The cost of raw material nickel (OH) is higher. The cost of processing and manufacturing large-energy batteries may be higher.
