Veritasium dives into the wild, billion-dollar hunt for the perfect high-energy battery, tracing the journey from the first rechargeable lithium cells to today’s lithium-ion workhorses—and the elusive dream of taming pure lithium metal for even more juice. Along the way we meet the tiny dendrite needles that kill batteries (and make them explode), hear from top scientists and engineers, and witness jaw-dropping demos (yes, including explosions).
Backed by experts from Imperial College and General Motors, this slickly produced video breaks down how batteries work, why power density has soared, and what hurdles remain before we can truly charge our gadgets in seconds and ditch range anxiety forever.
