Advantages to Nickel Metal Hydride Batteries

Posted on: Monday, March 24th, 2008 in: Reviews

What are the Advantages to Nickel-Metal Hydride?
• 30-40% higher capacity than standard nickel-cadmium. Nickel-metal-hydride has potential for yet higher energy densities.
• Less prone to memory than nickel-cadmium - fewer exercise cycles are required.
• Simple storage and transportation - transport is not subject to regulatory control.
• Environmentally friendly - contains only mild toxins; profitable for recycling.

Nickel-Metal-Hydride Batteries

Posted on: Monday, March 24th, 2008 in: Information

Research on the nickel-metal-hydride system started in the 1970s as a means of storing hydrogen for the nickel hydrogen battery. Today, nickel hydrogen is used mainly for satellite applications. Nickel hydrogen batteries are bulky, require high-pressure steel canisters and cost thousands of dollars per cell.
In the early experimental days of nickel-metal hydride, the metal hydride [...]

• Memory effect - nickel-cadmium must periodically be exercised (discharge/charge) to prevent memory.
• Environmentally unfriendly - nickel-cadmium contains toxic metals. Some countries restrict its use.
• Relatively high self-discharge - needs recharging after storage
