The performance results were equally impressive. When charged at an extremely fast rate – achieving a full charge in just over a minute – the battery retained half the capacity of one charged 25 times more slowly. At an intermediate charging rate, the battery retained over 80 percent of its initial capacity after more than 25,000 charge-discharge cycles. This level of durability far exceeds that of conventional lithium-ion batteries, which typically experience similar capacity degradation after only about 1,000 cycles.

This is impressive re-charging performance. Hopefully we’ll lithium-sulfar batteries in real products in the next ~5 years/

Are they more dangerous though? It’s an exciting gamble these days will this cheap electronic device become a smoking hole in the ground?
