Many equipments will use Lithium ion battery for power supply in future

In future, most of remotes (include: TVset, set-top-box, Air conditioner, etc.), wireless keyboard, wireless mouse, LED flashlight, alarm clock, Electric toys, etc., will use an universal model Lithium polymer battery (The battery's size will be small, maybe the capacity will be less than or equal to 300mAh.) for power supply. Will not use "AAA" or "AA" size battery.
