Let’s make this one easy to understand. Traditional lithium ion batteries are what keep humanity from creating more incredible technology. Despite that fact, you’ll find lithium ion batteries in smartphones to Teslas and Priuses. The way they work is via shuttling positive lithium ions between microscopically thin sheets of carbon graphite located at each electrode. But as these sheets age, their capacity and discharge performance degrades, and eventually they crack, rendering the battery dead and unless.
University of Southern California have therefore done away with silicon sheets entirely. According to a study published in the journal, Nano Research, a team headed by Viterbi School of Engineering professor Chongwu Zhou instead uses fields of porous silicon nano-tubes to shuffle electrons without wearing down and without losing capacity — thus allowing for extremely timely charges and longer lifespans. A provisional patent indicates that this could hit the market in 2 to 3 years.
That’s right; give another round of applause to science.
