Disadvantages of 18650 Ni-MH battery
1. Poor energy specific density
The specific energy and energy density of nickel metal hydride still cannot meet the requirements of PHEV and EV; that is to say, the battery storage capacity of the battery is low, and if it is used for a short time, it will run out of power.
2. Compared with lithium batteries, batteries still need to be improved
The rapid development of nickel-metal hydride battery technology is almost mature, and the space for battery performance improvement and cost reduction is very limited.
3. The cost of raw materials is relatively high
The raw material nickel (OH) is expensive, and the cost of producing high-energy batteries may be higher.
