The negative electrode in this type of battery is an intermetallic compound that includes nickel. The positive electrode is nickel hydroxide. Because the components are not consumed during discharge, NiMH batteries are rechargeable.

NiMH batteries are more expensive than alkalines. A typical battery gets about 500 charges before reaching end-of-life. Unfortunately, performance degrades with discharge and you notice a definite drop-off in power as time goes by. “The shelf life of (unused) NiMH batteries is typically shorter, around 3 to 5 years, due to their high self-discharge rate." – Battery University. NiMH batteries also take quite a long time to charge.

Ni-Zn Batteries 

Ni-Zn batteries are still relatively less common in the market compared to well-established battery technologies like Li-ion batteries.

Ni-Zn batteries, or Nickel-Zinc batteries combines the benefits of both NiMH and alkaline batteries. They offer a higher voltage than NiMH batteries, typically around 1.6V, which can provide better performance in devices that require a bit more power. Ni-Zn batteries are rechargeable and have a lower environmental impact compared to traditional alkaline batteries. 

“Ni-Zn batteries are specifically designed to discharge the energy very rapidly in the battery. That is what power density does [enable high discharge rates over short periods of time], versus the energy density; high energy density batteries that discharge at lower rates for prolonged periods of time,” said Stave Jennings, a Sr VP Sales & Marketing for a manufacturer of Ni-Zn batteries which means that they’re well-suited for devices that require high power for short periods, for example, flash units in cameras.
