Lithium ion Rechargeable Batteries by Dan Hagopian
Lithium ion rechargeable batteries are by far one of the most important technologies that have been developed over the last 10 years. Lithium based batteries are used in most portable devices from PDAs to laptops to digital cameras. Lithium ion rechargeable batteries are not hazardous when... In some of the lithium batteries at www.BatteryShip.com for example the electrolyte is a gel-like polymer film that allows ion exchange. ... Again let me stress that when sealed and used according to the recommendations of the manufacturer lithium ion rechargeable batteries are not hazardous.

The Battery - Cathodes, Anodes, and Electrodes (Part 2 of 2)! by Dan Hagopian
In part 1 of “The Battery - Cathodes, Anodes, and Electrodes” we discussed how engineers manufacture disequilibrium to create free negative electrons so that the positive atoms will attract the electrons at the positive electrode, thereby creating an electron flow. ... A representative formulation is a solution (1:1 by volume) of ethylene carbonate and propylene carbonate containing a suitable lithium salt such as lithium hexaflourophosphate, LiPF6, which raises the conductivity of the electrolyte.
