Conventional lithium-ion or nickel metal hydride rechargeable batteries contain active material that is placed into a thin film.

传统的锂离子以及金属氢化物镍蓄电池中所含有的活性物质被放置在一个薄膜中。

While far trickier to handle, lithium-ion cells pack twice the punch of their nickel-metal hydride equivalents.

但更为棘手的是，锂电池会是同等的金属氢化镍电池组效能的2倍。

Phones also run several kinds of batteries, ranging from lithium ion to lithium polymer to Nickel Metal Hydride (NiMH).

FORBES: Smarter Phone Charger On Way

Johnson Controls is positioning itself to be a technology leader in hybrid car batteries as the industry shifts to lithium ion batteries from nickel metal hydride batteries used in today's hybrids.

FORBES: Control Freaks

To be technical they have moved from nickel cadmium (NiCad), through nickel-metal hydride (NiMH) to lithium-ion (Li-ion).
