Well, CAT does say that theirs are the “ World’s First Graphene battery on power tools.” But this could just mean the battery cell contact is graphene-coated. Generally, higher conductivity means lower resistance, which means less heat.īut, is this same technology available to other brands? What’s the likelihood that CAT with their nascent cordless power tool line, has access to special tech or Li-ion battery cell tech that other brands are locked out of? It seems there’s some graphene used in the cathode (-) end of the battery cells – at the least. Looking at some scientific paper abstracts that go back to at least 2013, graphene improves electron conductivity of lithium ion battery cathode materials. Graphene’s low resistance keeps cells cooler under heavy load.Graphene polymer is integrated into the cathode of battery cells to get enhanced performance of battery. In this graphic, there’s an asterisk with fine print: Think about diamonds, and how you can have 1 carat jewelry that costs thousands of dollars, or some cheap industrial diamond particle abrasives. Graphene is a special and exotic material, but it can also be rather basic. There is a lot of research going on right now, with things like graphene nanotubes.īut, you can also create graphene by sticking a piece of Scotch tape to a block of graphite (basically pencil lead material) and peeling it off gently. Scientifically, graphene is a single layer of carbon arranged in a hexagonal lattice, and it has some unique properties. (Note, in other places CAT Power Tools says the full charging time is 20 minutes.)īut what’s this graphene stuff all about? High max discharge current service tool betterĪn 18 minute full charge time? That’s not “instant” as they say, but it’s still incredibly impressive. ![]()
