Question

Please help me fill in the blanks with the words listed below as option to fill them.

1. has almost twice as great a mass percent Li as__________ .

2. This___________why LiMn2O4cathodes deliver less power on discharging. A Li-ion battery produces power by the migration of_____________, but not all the___________________in the material migrates during a full charge. The greater percentage of Li in the___________________material, the more___________________that migrates and the ____________power can be produced upon discharge.

Li+

cathode

O2

graphite

doesn't explain

less

anode

more

LiMn2O4

LiCoO2

definitely explains

Part D

In a battery that uses a LiCoO2 cathode approximately 50% of the lithium migrates from the cathode to the anode on charging. In a battery that uses a LiMn2O4 cathode what fraction of the lithium in LiMn2O4 would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode?

Express your answer using two significant figures.

Explanation / Answer

1. LiMn2O4 has twice as great a mass percet Li as LiCoO2

2. This doesn't explains why LiMn2O4 delivers less power on discharging. A Li-ion battery produces power by the migration of Li+, but not all the Li+ in the material migrates during a full charge. The greater percentage of Li in the cathode material, the more Li+ that migrates and the more power can be produced upon discharge.

Part D.

In a battery that used LiCoO2 cathode, If 50% of lithium migrates from the cathode to the anode on charging. Then the battery usinf LiMo2O4 cathode that fraction of lithium migration would be almost 90.00 %
