Twenty years ago when the first cell phones came out, they had NiMH batteries.

Of course, Boeing might be better off choosing a safer, but less powerful NiMH battery.

"It's now apparent that some have a very good prognosis, " said the NIMH's Dr. Insel.
Phones also run several kinds of batteries, ranging from lithium ion to lithium polymer to Nickel Metal Hydride (NiMH).
To be technical they have moved from nickel cadmium (NiCad), through nickel-metal hydride (NiMH) to lithium-ion (Li-ion).
One of the fictional Rats of Nimh was called Justin, a source of some embarrassment during English lessons.
In other words, Li-ion is slowly taking over the hybrid market as NiMH goes the way of the dodo.

The conventional logic has it that Li-ion offers greater storage in a more compact space compared to the less expensive NiMH.

As a continued indication of a trend away from NiMH, full hybrid EVs will bump from 0% Li-ion-powered to 17% over the same interval.

The bottom board is home to four AA batteries (NiMH), a pair of motors and wheels, a power connector and switch plus some infrared sensors.
And the NIMH is testing whether giving Pandas patients injections of plasma from healthy donors, intravenous immunoglobulin (IVIG), can reset their immune systems and for how long.
With all the electronic devices in our lives these days, it makes environmental (and financial) sense to switch to rechargeable nickel metal hydride (NiMH) and lithium ion (Li-Ion) batteries.
Also included in the package are a charger, an antenna and a 1500 mAh NiMH battery that promises up to two hours of talk or 36 hours of standby time.
On that crucial dimension, if lithium-ion batteries are a 3, the next best technology, NiMH is a 2, and a lead acid battery, like the one you use in your car, gets a 1.

The system also features a NiMH rechargeable battery, offering ten hours of music play time (at medium volume), a 3.5mm stereo input for wired devices, and includes a carrying pouch for safekeeping on the go.

The battery cells were fabricated by adapting a process developed by another team at the university which is designed to make it faster to recharge the batteries than lithium ion (Li-on) and nickel metal hydride (NiMH) equivalents.
The Tesla Roadster, which indeed uses Li-ion batteries, stores 56 kWh of electric energy and delivers up to 215 kW of electric power (a NiMH battery pack with the same electric energy would weigh over twice as much).

Plus, according to Andy Chu, vice president of marketing and communications at battery-maker A123, because hybrids do not rely solely on electric, they can afford to sacrifice some energy density and stick with the NiMH without fear of running out of juice.

One alternative is a proposal that the NIMH has been developing for three years, called the Research Domain Criteria, which will move toward funding research that examines core biological features of illness shared by several disorders, such as problems in brain circuitry, rather than the current practice of focusing on symptoms specific to one disorder, according to Dr. Insel.
