Future Sony batteries to be 40% greater capacity
 

Sony has been working on a sulphur-based battery technology to achieve a 40% run time increase over the current lithium technology. The expected date to see commercialised batteries of this technology in the market is 2020.

First off, more power in batteries is always better, but I gotta say... Starting with NP-1 batteries 20 years ago that would power a beta cam for a half hour or so - I shot yesterday with a U60 that powered my FS5 for an 8 hour day. Not sure how much more I need, although I gotta say if they came up with one that gave me 40% more at the same weight and cost - I'd switch over!

Sony always have made great batteries, I still have a few original npf 970's from the sony camera's I used to own and they now power some video lights like for ever though I have to say the Panasonic battery from my gh4 never seems to run empty either :)

As far as cameras go I agree with you, but I think battery technology is going to be a critical area for R&D over the near future in two very different areas.

First is micro electronic devices - smartphones being most obvious. At present the battery is a major element of size, weight etc - make a battery 40% smaller with the same capacity and expect it to be popular. Second is the other end of the scale, with huge research going into batteries for electric cars - it's the size, weight, cost of batteries that are probably the main limiting factor on greater electric car uptake.

Make a big breakthrough with battery tech and the rewards could be very high. (Even if not through camera batteries! :-) )

My new phone (Nexus 6) will go from almost empty to almost full in less than an hour. Thanks, USB-C! I don't feel the capacity is needed in phones, but in watches and other nano devices for sure - and the super-fast charging will be the next push IMHO.

Not true! I depends on the model. I love my BPU series batteries and they keep runnning great year after year, but the GL series v-lock batteries are complete garbage. I have five of them that crapped out after about a year, while the 3rd party brand batteries I bought about the same time just keep on going strong year after year.

I wonder what the explosive potential of sulphur batteries will be? Note that the word comes from the Indo-European root meaning, "to burn".

Thinking back to chemistry lessons of many ears ago I remember burning sulphur and my memory is that it burnt quite slowly - far, far less flammable than Lithium! (I also remember being shown a small piece of lithium metal put in water!)
