What is the operating temperature range of a NiMH battery?
Fig. 1. NiMH battery schematic [ 5 ]. Although NiMH battery is able to operate in a wide temperature range of −20 to 70 °C, several leading eCall system manufacturers have recently demanded an even wider operating temperature range of −40 to 80 °C to cover all extreme weather conditions.
What happens if a NiMH battery reaches a high temperature?
Although NiMH battery can function in a wide temperature range, extreme temperatures cause some operating difficulties. Exposure to elevated temperatures lead to premature NiMH battery material failure. At ultra-low temperature, NiMH battery's alloy anode experiences sluggish bulk reaction and decreased surface reactivity.
What is a NiMH battery?
The Cobasys’ NiMH batteries utilizing these materials are among the most advanced prismatic NiMH batteries on the market today. The NiMH Battery The NiMH battery is termed an alkaline storage battery due to the use of potassium hydroxide (KOH) as the electrolyte. Electrically, NiMH batteries are very similar to nickel cadmium batteries.
How much hydrogen does a NiMH battery hold?
Today’s practical materials for NiMH batteries hold between 1% and 2% hydrogen by weight. (1) Many elemental metal hydride materials exist but were not practical for battery applications due to the high equilibrium pressure exhibited by these materials at room temperature.
How long have NiMH batteries been in development?
NiMH batteries have been in development for well over twenty years, but were mere laboratory curiosities before the development of advanced metal hydride electrodes that were capable of being charged and discharged in a cell environment without failure.
