From cleaning our homes to analysing the soil composition of distant planets, robotics has allowed our society to reach farther than ever before. We are still at a point where we are technologically hampered, however, as robotics can only be pushed so far with our current innovations. One of the biggest hurdles for robots and their potential is power - specifically battery power.
Without sufficient energy reserves, robots cannot function. It is a significant limitation but not an impossible barrier to cross, as scientists across the globe push to advance battery technology.
To the outside observing, battery technology seems to develop in ebbs and flows. It has taken us a long time to push beyond the traditional heavy acid batteries that we know - such as car batteries or the humble AA battery. In 2019, the Nobel Prize in Chemistry was awarded to the developers of the lithium-ion battery. Although the research was originally published in the 1970s, it wasn’t until recently that this revolutionary battery technology was brought to the mainstream market.
Today, lithium-ion batteries are ubiquitous - they are used to power our smartphones, laptops and even our electric cars use lithium-ion batteries. They hold a greater charge, last longer and are incredibly lightweight compared to the batteries that were once popular. Even though lithium-ion batteries are incredibly widespread today, scientists are still struggling to unlock their true potential and much remains unknown about them due to their complicated.
