Every day, we see news about large items transitioning from fossil fuels to batteries: cars, trucks, boats, trains, etc. It's because new technology is enabling the batteries to add more power and be a more realistic alternative to gas or diesel.  

However there are many breakthroughs in the battery world that also enable products to get smaller and smaller – in this case tiny robots that can deliver targeted drugs to the right part of the body, or robots with sensors that can detect leaks in gas pipelines. 

Whatever the end use is, manufacturers need to understand how to power these new devices they are developing. This is why breakthroughs in battery technology are so important.
