The other new Murata battery - high temperature - has been reviewed by Arrow

And this distributor from Taiwan

Perkylad,
Maybe it is wishfull thinking but I thought it would be good to share these thoughts.
Interesting thoughts TD and good work on your dismantling of the coin cell too. The battery and the capacitor share a striking similarity in that they are both essentially 2 conducting electrodes separated by 'stuff'. I'd never thought of the possibility that they could be combined though till now...
D This would also explain why did didnt needed the line anymore.
Pp1, many thanks !
So many clues towards cr2032 batteries.
I think that Murata figured out that whilst working on the Umal that further integration towards one component should be the next step (hassle free assembly):
A widen the license to batteries.
B Ask cap-xx for 3volt for better fit with the battery.
C start development in 2015. 4 years from idea to mass mfg is based on my experience a realistic timeline.
Since I’m not a specialist in batteries and supercaps, I was wondering if it would be technical feasible to combine those into one ?
Here's another link Tradingdutchman which may help:-

Still struggling with this text in the audited results ended 30 june 2016:
In April 2016, Murata and CAP-XX reached agreement to broaden the existing licence agreement to include battery markets and additional supercapacitor sizes. Following this agreement, Murata announced in late June 16 that it was launching a range of lithium ion batteries. Murata has confirmed that mass production of the new device commenced in June 2016 and that it plans to expand its product line-up to meet future demand for large capacity devices
I also thought that the 3volt was developed on specific request from Murata, but I can’t find this back anymore, does someone still remember this and if so, share a link ?
Thanks for the update Dutch
Received the murata cr2032R coin batteries finally. I opened one and compared it with a normal Grundig cr2032 coin battery.
Both have equal stack built up, so no additional layers/parts present in the murata version. No sign of a seperate thin supercapacitor inside the housing.
So I think the high drain is done by special herbs and spices which still might be cap-xx related, but this is something where I have no idea on how to check this.
Means we need to be patient for at least another week..
I will anyway use the batteries for my car fob :-)
Thanks Tony.
Btw. Still nothing Delivered yet. Track and trace still mentioning today....
Could be the electrolyte, or the separator, or the active materials. These others also cpx IP. Probably the active materials are M's own, who say they have an innovative new casing too. I was looking for those diagrams for you, having seen them a few months ago.
PM is presenting at Sensors Expo again this June.
Nice technical article about murata coin cells (while searching for exploded view drawings):
https://www.onelectrontech.com/cr-sr-lr-micro-batteries-coin-manganese-dioxide-lithium-mercury-free-silver-oxide-alkaline-manganese/
Gives me the impression that the electrolyte herbs have been improved (which is the core of cap-xx ip and competence):
The electrolyte in the core of the battery is a composite made from the molten Lithium salt and an organic solution to promote the high-density power exchange from the core to the exterior interface. These batteries can provide high voltage and high energy density, as well as good performance over a wide working temperature range.
This would mean that when opening the ordered cells, nothing can be seen and still no conclusions can be drawn yet and we simply need to wait and pray a bit longer untill we learn from it by increased royalty results from murata.
Anyway, tracking says the coins will be delivered today, for sure I will open one during the weekend....
Just got the news that the ordered Cr2032R High Drain Murata coin cells are finally in transit to my home adress, so hopefully I can analyse them this weekend :-)
Still waiting for the high drain cr2032 from murata. Just contacted the distributor and they gave me a new date... 23 march... I hope it is simply due to too much demand...
When sinuss called me, they confirmed mid february.
I personally have not got a Scooby-doo however very intrigued.
When are you due to get them Dutch?
yes thats alright from AVX isn't it
dutch, long been curious if laminated type lith batt is updated UMAL. I'll have a dig.
Will do DutchMan, still researching and still keeping the faith.
Court case was updated yesterday.
AVX released earnings yesterday , some quotes from it
"However, we continue to be optimistic that the evolution of new electronic devices and content will create strong demand for our components and interconnect, sensing and control devices and provide growth opportunities in the long-term.” "
"Market demand for certain advanced products remained strong, particularly in the aerospace, defense, and medical markets. "
Nobody ????
Still waiting for my ordered cr3032 high drain batteries for analysing.
I stll couldnt find any technical clues on the internet if cap-xx license is involved.
If anyone has clues, would you mind sharing ?
