00:00Why do batteries become more and more exhausted with use?
00:03We will enlarge a lithium-ion battery 100,000 times,
00:07pass through the active and inactive material layers,
00:10and enter polycrystalline particles the size of red blood cells to study its
00:14working principle from the atomic level.
00:16This is the basic element in a lithium-ion battery.
00:20When the battery is charged, lithium atoms break down into electrons
00:25and lithium ions. They move from the cathode to the anode.
00:29The lithium ions first pass through the electrolyte solution.
00:32There is an isolation membrane in the solution that prevents the cathode from
00:36connecting with the anode.
00:38Contact causes an electrical short circuit.
00:41As lithium ions enter the solution, they are attracted by its positive charge
00:46and form a shell. This shell allows the lithium ions to float freely
00:51in the solution. When the lithium ions pass through the electrolyte solution
00:55and reach the anode,
00:57the solvent molecules will interact with the graphite particles.
01:00The outer shell reacts to form a protective film.
01:03This film extends the life of the battery but also consumes 5-10 percent
01:08of the battery's lithium,
01:09which is equivalent to a 5-10 percent reduction in capacity.
01:13Now the lithium ions will pass directly through this layer to the anode
01:18and they will be stored in graphite particles. Since the electrolyte solution
01:22and the isolation film are both insulators for electrons,
01:26the electrons can only reach the anode through the external circuit,
01:29combine with lithium ions and then store them in the form of one lithium atom for
01:34every six carbon atoms until the battery is discharged.
01:38The nickel crystal structure inside the cathode is electronegative
01:42and attracts electrons to separate from the lithium atoms.
01:45The electrons will enter the cathode through the graphite
01:48along the external circuit. The lithium atoms that have lost electrons will
01:52become lithium ions
01:54and then pass through the electrolyte solution and return to the cathode from
01:58the anode as they are discharged.
02:00The circulating electrons and ions of discharge move back and forth between
02:04the cathode and anode.
02:06Some lithium ions are embedded in the graphite particles and cannot be
02:10deintercalated,
02:12resulting in fewer lithium ions that can move freely,
02:15which reduces the battery's discharge capacity. This is why the battery becomes
02:20more and more exhausted as it is used,
