Lower energy density compared to lithium-ion batteries: NiMH batteries have a lower energy density than lithium-ion batteries. Energy density refers to the amount of energy stored per unit volume or weight. For instance, lithium-ion batteries can provide up to twice the energy density of NiMH batteries. According to a study by the U.S. Department of Energy in 2021, this difference limits the range and efficiency of vehicles using NiMH technology, making them less attractive for modern electric vehicles (EVs) that require long ranges.
Self-discharge rates are higher: NiMH batteries exhibit a higher self-discharge rate compared to lithium-ion batteries. Self-discharge refers to the loss of charge when the battery is not in use. Research conducted by the American Chemical Society in 2020 indicated that NiMH batteries can lose about 15-30% of their charge per month. This impacts the practical usability of these batteries, especially for vehicles that may not be used frequently.
Temperature sensitivity: NiMH batteries are sensitive to temperature extremes. Their performance can decrease considerably in very hot or cold environments. According to a study from the Journal of Power Sources in 2022, temperatures below freezing can lead to reduced capacity and efficiency. This makes NiMH batteries less reliable in varying climate conditions that modern vehicles may encounter.
Weight and size limitations: NiMH batteries tend to be heavier and bulkier than their lithium-ion counterparts. This additional weight can impact overall vehicle efficiency, particularly in hybrid and electric vehicles where weight reduction is critical. A report from the Automotive Research Center in 2020 noted that the increased weight of NiMH batteries may adversely affect vehicle handling and fuel economy.
Shorter lifespan in some applications: The lifespan of NiMH batteries is often shorter in certain vehicle applications than that of lithium-ion batteries. Although current models can last between 5-10 years, studies have shown that the usable life can diminish under high-stress conditions. A research paper published by the Institute of Electrical and Electronics Engineers (IEEE) in 2021 suggested that efficiency and charge cycles influence lifespan critically.
