Lithium Ion Batteries Rely on Microporosity to Transmit the Electric Charge

The positive electrode of lithium ion battery, the Cathode, is made of highly purified lithium oxide, and the negative electrode, the anode, is made of graphite. Both are sandwiched to the conductive surfaces, usually made of aluminum or copper. Structurally the electrode and conductive surface are made to be one unit. The separator, soaked in electrolyte ensures that that short circuit does not take place causing explosion or fire. Actually, the separator does not separate but only rations the ion flow be
