THINERGY MicroEnergy 4.0v solid state cells

[hopkins]

THINERGY Micro-Energy Cells 4.0volt postage stamp size batteries. 0.7mah rechargeable and
ultra low self discharge.

Lithium cobalt oxide -cathode
Lipon for the electrolyte which is solid state
Lipon = lithium phosphorous oxyous nitride
lithium metal for the anode


from Infinite Power Solutions are ultra-thin, solid-state, rechargeable, energy
storage solutions that serve a variety of vertical markets. Able to operate in

temperatures ranging from -40ºC to +85ºC, the IPS MECs offer extremely low self discharge rates, low cell resistance and high power. An extremely thin form

factor allows for easy integration onto or embedded into PCBs, IC packaging,
multi-chip modules (MCMs), Systems in Package (SIP) or even the structural

material associated with the application itself. Moreover, THINERGY MECs are ideally suited for use with all forms of ambient energy harvesting techniques

for recharging—such as solar, thermal, RF, magnetic and vibration energy
—delivering a safe, reusable and clean power source for today's electronic
devices and systems.

Claims a 1 nano amp leakage current

actual output is just 4.0volt .

Sort of a hybrid storage device with the best qualities
of batteries and super capacitors, claims the mfg.
scaling up to larger maH cell capacity hopefully is in the works.

news story on how this low self discharge technology would allow these cells to recharge themselves from ambient low power sources.

I dunno about you, but I am unimpressed by so much effort into less than 1ma storage device. I would say a solar cell the same size probably puts out as much energy and probably costs less.

Lynx - I agree that one of these is insignificant for driving a flashlight.
But I finally got onto their web site and watched the vids on the development
tools they sell with these cells.

Gave me some ideas like an energy harvesting
device integrated into a flashlight that would keep the Li-ion batteries at full charge until it was needed.

OK, but the solar cell is only good when there's sun shining -- so stick one of these on the back of the solar cell and you get round-the-clock power to keep a CMOS device running.

Regarding how much energy a solar cell puts out -- it puts out 1 million mAh, if it puts out 1mA and you leave it in the light for a million hours. Comparing the power of solar cells and batteries makes sense, comparing the energy doesn't.

Will 4 of these power my M@g 623? :naughty:

It is a very interesting cell. And don't everybody forget, this is just a "beginner" model. Who knows where this will end up?

Here's a link to new energy harvesting ribbon that may be just right
to recharge these thin cells or any other cells eventually.

Of all piezoelectric materials, PZT is the most efficient, able to convert
80 percent of the mechanical energy applied to it into electrical energy.

I immediately thought of this stuff built into shoes and
used to generate a current to recharge batteries.

Interesting stuff.
