 LITHIUM-ION BATTERY Lithium-ion batteries are secondary rechargeable batteries.  It has an emf that varies from 3.5-4V depending on electrode potential. Construction The 3 primary components of a lithium-ion battery are: The anode is lithiated graphite (graphite in which lithium ions are inserted in between the layer of carbon atoms. The cathode is a mixed metal oxide like LiCoO2,  LiMnO2 or LiFeO2  The electrolyte is a lithium salt (LiPF6, LiBF4, or LiClO4 ) in an organic solvent. This is rechargeable. This is done by applying a higher voltage than the voltage of the battery, across the electrodes. The lithium-ion moves from anode to cathode during discharging and from cathode to anode while charging. Cell reaction Anode : LixC6  --->   6C + x Li+  + x e- Cathode : Li1-x CoO2 + x Li+  + xe ----->   LiCoO2 Overall cell reaction : LixC6 + Li1-x CoO2  ------->   LiCoO2  +6C Characteristics Depending on ...

 STARLINK HAD TAKEN THEIR INITIAL STEP IN INDIA Elon Musk's Starlink had taken its initial step to enter the Indian market. SpaceX had Registered its Indian sub-company named Starlink satellite communication private limited. As a result, star link can now request approval and can start their bank account in India. The 100% shares of  Starlink satellite communication private limited is owned by SpaceX. Star link's Indian Roadmap 1st phase In the first phase, they will provide free Starlink connectivity to 20 schools in Delhi with connectivity to over 80 schools in village areas in Delhi. 2nd phase In the second phase, they take upon 4 villages in the extreme sites in India in a total of 12 district 3rd phase In the third phase, by the end of December 2022, they are targeting 2 lakhs connectivity all over India mostly in remote village areas
