At present, the energy density of lithium-ion batteries can reach 300Wh/kg, while the highest energy density of NiMH batteries is only 140Wh/kg. using NiMH batteries as power batteries, new energy vehicles will have a very short driving range. However, the lower energy density makes the safety of NiMH batteries better than that of Li-ion batteries.
NiMH batteries tend to have a higher self-discharge rate than lithium-ion batteries, which can lead to loss of charge when not in use. This is particularly problematic for devices that are used infrequently. 3. Voltage Limitations The nominal voltage of NiMH cells is 1.2V, which can be insufficient for devices designed for 1.5V alkaline batteries.
Compared with nickel-chromium batteries, NiMH batteries have the advantages of low memory effect, good environmental performance and long service life, and the storage capacity is about 30% higher than that of NiCd batteries. However, the cost of NiMH batteries is much more expensive than NiCd batteries.
When compared to other battery types, NiMH batteries have fewer hazardous elements, especially cadmium, which is bad for the environment. They now meet contemporary environmental regulations, making them a more environmentally friendly option. 4. Safety Features
Memory effect was a problem with older NiMH battery generations, where the battery would lose capacity if it wasn't completely depleted before being recharged. Modern NiMH batteries, on the other hand, have greatly mitigated this problem and may be charged whenever needed with little to no capacity loss.
They capture energy when drivers brake or decelerate and supply energy when they accelerate. NiMH battery packs are integrated into the vehicle's powertrain system. Although NiMH batteries tend to have lower energy density compared to lithium-ion batteries, they can still pack enough energy to power a vehicle.
