According to Frost and Sullivan, the average power degradation in a lithium ion battery can be approximately 50% of their charging capacity after two years. As most cell phone users notice after a short time of ownership, the battery in their phone does not hold a charge like it did when it was new. They must recharge their phones more and more often and be more conscious of saving power.

MTI Micro’s strategy is to provide Mobion portable power products for use in the multi-billion dollar consumer electronics industry for applications including cell phones, digital cameras, PDAs, MP3 players and other handheld electronic devices. The Company’s Mobion, 100% methanol feed, passive DMFC technology has been demonstrated in fully-functional prototypes and concept models in three primary product directions: external cord-free rechargeable power packs, attached fuel cell power sources and embedded micro fuel cell designs.
