The Lithium-Ion Miracle
How 1970s chemistry breakthroughs unlocked the portable revolution.
- The Weight Problem
Shedding the Lead
For 150 years, lead-acid batteries were too heavy to carry. To go mobile, science needed the lightest metal on the periodic table.
- Atomic Choice
Why Lithium?
Lithium is the third element on the table, offering a high electrochemical potential with minimal mass. It was the industry's ultimate 'holy grail'.
- Origin Story
The Oil Crisis Spark
In the 1970s, Exxon hired Stanley Whittingham to find energy alternatives to oil. He built the first working lithium battery using titanium disulfide.
