- Lithium-ion batteries have revolutionised our lives and are used in everything from mobile phones to laptops and electric vehicles
- In the early 1970s, Dr.Whittingham, used lithium’s enormous drive to release its outer electron when he developed the first functional lithium battery
- Goodenough doubled the lithium battery’s potential, creating the right conditions for a vastly more powerful and useful battery.
- Yoshino succeeded in eliminating pure lithium from the battery, instead basing it wholly on lithium ions, which are safer than pure lithium. This made the battery workable in practice.
- The advantage of lithium-ion batteries is that they are not based upon chemical reactions that break down the electrodes, but upon lithium ions flowing back and forth between the anode and cathode.
