The Laptop Battery – The Lithium Ion Battery System
Applications: Laptop computers, advanced cellular phones, personal data assistants, and military electronics, such as mine detectors, satellites, military radios, and thermal weapon sights. Cathode/Anode/Electrolysis: Lithium Cobalt Oxide/Graphite/Lithium hexaflourophosphate. It should be noted that noted four types of electrolytes are used in Lithium-ion batteries: liquid electrolytes, gel electrolytes, polymer electrolytes and ceramic electrolytes. Lithium hexaflourophosphate, a liquid electrolyte is the most commonly used electrolyte in Lithium-ion battery systems. Chemistry:
LiCoO2 ßà
Li1-xCoO2 + xLi+ + xe- cathode
Distinguishing Characteristics:
Fun Fact: Lithium has the lightest weight, highest voltage, and greatest energy density of all metals. Note: The active materials contained within the Lithium-ion battery, operate by reversibly incorporating lithium into the interstitial space with the host material electrodes. Hence, host materials for the electrodes considered most suitable for the Lithium-ion cell battery system are metal oxide (tunneled structure) cathodes and graphitic (layered structure) anodes. |
