I've been reading a lot of battery patents lately, and there are a lot to read. This battery does not appear to all that unique in the context of old patents ... and the story is typical of "science by PR release" which is a common practice these days. It is overhyped for sure.
Using carbon for both anode and cathode (dual carbon) is far from new. There are patents from the 1800s using this approach. However, it is hard to make carbon conductive enough for a large battery. When graphite and CNT came along, the patents for dual graphite followed since fibrous carbon can be made more conductive than soot. The point is that the "lack of details" may be related to lack of patent coverage - and the attempt to keep as a "trade secret" certain details that have been covered in prior art. Carbon and particularly CNT is an excellent battery material, but you can find dozens of advanced batteries using this approach. Has anyone seen any IP from them? I can find nothing under Power Japan. An inventor from Union Carbide was named Ryden, but that does not seem to be the connection. -----Original Message----- From: Chris Zell It's interesting but is it real? I wonder about the lack of details. -----Original Message----- From: Brad Lowe This sounds pretty revolutionary battery technology: Japanese power company, Power Japan Plus has announced the development of a new type of battery intended for use in automobiles and other applications, the Ryden or dual carbon battery. The company claims the battery charges 20 times faster than current lithium ion batteries, doesn't heat up, so it doesn't require cooling and is cost competitive with other current batteries used in cars and trucks. They believe the battery will be a game-changer, leading to a surge in sales of hybrid and all electric vehicles.
