Nikkei's reporting that Hitachi Maxell, in association with Nagasaki University, NIAIST, and Fuji Heavy Industries, has developed a new kind of lithium ion battery that can supposedly store 20 times the power, but is also cheap and easily mass produced. Apparently this new kind of battery drops cobalt, an expensive staple of the traditional Li-ion recipe, instead making use of nano-infused lithium with manganese. You know how it goes though -- unrealistic and exponential battery developments are all well and good, but until we see it productized, we're not exactly liable to buy into the hype.

Though Hitachi Maxell didn't see fit to dole out any images to accompany its newest duo of products, at least they're pretty self-explanatory. Up first is the Audio Transmitter / Dongle, which plugs into any iPod's dock connector input and enables audio to be "processed with SRS WOW HD audio enhancement before being transmitted via Bluetooth to any BT-enabled headset or speaker accessory." For those who aren't exactly wowed, you can flip off the process with a button on the appendage. Next up is an apparently unnamed Bluetooth 2.0 stereo headset, which doesn't seem to do anything out of the ordinary. Continuing the ambiguous trend, we're also left sans a price or release date -- thanks, Hitachi Maxell.

Good morning, kids. Are you ready for the optical disc format of the day? It's Hitachi Maxell's 1TB stacked volumetric optical disc (SVOD) array, comprised of rather thin DVD-size discswith DVD-size capacities: 9.4GB total storage each on two 92µm thick data layers. Yeah, we know, we promised a terabyte; well, watch and learn. These polycarbonate discs may be too thin to be manufactured from typical plastics, but they can be stacked in an optical array 100 tall, and 6.5 x 13.3 x 16.1cm (2.5 x 5.2 x 6.3-inches) in size. Even though Hitachi Maxell wants to make the terabyte carts relatively cheap at ¥40,000 (about $340 US) and claims there are consumer applications, don't toss that HD DVD player just yet. It's pretty easy to realize why optical arrays are really of only limited utility for the end-user; if these should ever be popularized, we'd imagine it would serve first as data archival medium for businesses before you'd ever outfit your rig with, like, the high def optical disc system, dude.
