NEC LaVie MX: Reflective LCD & Li-Polymer Bat.

NEC LaVie MX: Reflective LCD & Li-Polymer Bat. - PCSTATS
Abstract: While the integration of the Crusoe processor would bring our attention to this notebook regardless, it is actually the screen that makes this notebook stand out among Crusoe-powered portables.

Lithium Polymer Batteries

Next on the list on cutting edge technology crammed into the 1" thick LaVie MX are Lithium Polymer Batteries. The new variant on the Li-ION batteries are rectangular in shape (~6mm in thickness or less), and allow for super-thin notebook integration. The technology does have some drawbacks in that the batteries are supposedly not well suited towards high power consumption notebooks. They are also more expensive then Li-ION batteries. Li-Polymer technology can provide 500+ charge/discharge cycles with no memory effect.

"Li-polymer batteries replace the liquid electrolyte with a polymer in gel or solid form. The polymer electrolyte provides the required electrode stack pressure, so the metal can is no longer required and it becomes possible to enclose the cell in a foil pouch. A laminate of aluminum foil and plastic, the pouch occupies less space and weighs less than the metal can. The foil pouch permits greater room for active material, and it can be readily formed in a shape closely tailored to the space available in the application. Moreover, the foil can reduce the cell weight by 50% or more."

With each of these technologies the NEC LaVie MX has made significant strides towards cutting-edge, high-tech portable computing. Li-polymer batteries are so new to the market that expectations abound towards higher power-densities and lower costs. With more Li-polymer batteries being produced cost will undoubtedly lower for the end-user. Whether the reflective LCD dispaly technology will prove itself in terms of power savings over that of convenience remains to be seen, but then again 11 hours battery life is simply unprecedented, so long as the sun's out!
