Instead, they ended up inventing a battery that can reportedly last for 400 years. This all happened when they were researching the properties of nanowires that are made of gold and embedded in a specific electrolyte gel.

When they were performing tests, they discovered that the battery had survived 200.000 charge cycles in three months, with no loss of performance. According to Good, this translates to the battery powering a normal smartphone or laptop for 400 years. Essentially, it would be obsolete to ever charge a phone or laptop again.
