Scientists at Rice University have speeded up the charging time by making one change in the battery. In tests, batteries made using asphalt charged to full power in just minutes. Additionally, the asphalt stopped the formation of deposits that shorten the battery life.
Professor James Tour remarked that this new discovery could potentially bring phones from zero to full charge within five minutes, rather than the typical two hours. According to Tour, the manufacturing process behind this new approach was simpler than earlier techniques. The Rice team has put the batteries through hundreds of cycles of testing to ensure stability.
From a business perspective, because people now keep their phone for quite a while before upgrading, they may not be willing to change their phone or buy a new battery. However, as the demands for the battery become stronger throughout the years, people will see the need clearer.
