بطارية من الزنك والهواء تنتج 1,4 V - 900Ah


(waterman) #1

السلام عليكم

توصل احد المخترعين الى انتاج بطارية جديدة تنتج 1,4 فولت و 120A أمبير بسعه 900 امبير ساعه

تكنولوجيا جديدة وتعتمد على مرور تيار من الهواء بين شرائح البطارية

سواء القطب الموجب او القطب السالب
وبينهم وسيط يحتوى على بودرة الكربون وبعض المواد الاخرة مثل ال Zink/KOH/O2

المزيد من التفاصيل

The Datasheets says:

Zinc-Air Cell (monoblock), rechargeable

Cell Chemistry: Zink/KOH/O2

Cellvoltage open circuit (uncompressed): 1.4 V
Cellvoltage (with load, 0.3 A/cm2) 1.0 V

Current (continuous): 100 A (0.3 A/cm2)

Current (1 minutes, max): 120 A (0.35 A/cm2)

Amp-hours (C/10): 900 Ah

Energy Density (30 A / 100 A): 580 / 450 Wh / kg

Energitthet (30 A / 100 A): 1500 / 1200 Wh / L

Power Density: 50 W / kg

Effekttthet: 135 W / L

Charge Cycles (0.1 C, 100% DOD):> 100
Cathode-area: 340 cm2, Make Electric Fuel (*)

dimensions (mm) (length x width x height): 205 mm x 30 mm x 120 mm

Weight: 2,0 kg

He said on the swedish forum:

The price of 1000 SEK is 70% dependent on the price of air cathode, especially in this prototype cell in which a ready and very expensive version of the Electric Fuel (EF) is used. In the future own cells meaning even air cathode was self-made, with more of a halved the price for it. Customer price at an average volume of production would reach around 1000 SEK per kWh, including profit margins and so on.

This prototype cell, 900 Ah, where 0.824 Ah, is obtained from each gram of zinc.

Cell voltage is 1.4 V and 1.0 V, no load at nominal load of 100 A, max 120 A.

Revolutionary Zinc-Air Battery Developed For EV Use

produce, high energy-density, and actually biodegradable. Moreover, Zinc is among the most abundant and inexpensive metals on earth and therefore Zinc-air batteries are not susceptible to materials shortages or production bottlenecks. But up until now Zinc-Air, arguably the “greenest” high-density battery technology, has had three drawbacks making it unsuitable for EV applications. APET believe that they have now overcome all three:
Weight - The usual materials needed to create a zinc-air battery are relatively heavy, but APETs new ZOE design creates a battery which has twice as many Wh/kg (watt hours/kilogram) as a typical lithium-polymer (Li-Po) solution.
Cost - Existing technology results in batteries which are quite expensive, but the new technology has yielded a phenomenal reduction in price, estimated at one-tenth of a Li-Po solution and one-fifth of a NiMH one.
Rechargeability - with traditional Zinc-air batteries, once the zinc has been exhausted they’re dead and cannot be recharged. Current units are designed to be disposable (and are in fact, biodegradable), but the new ZOE battery is designed to allow the casing to be taken apart and reused with a fresh batch of zinc. No external charging need take place. Moreover, the exhausted Zinc removed from the discharged battery can be reconstituted by the application of extreme heat, then simply placed in a depleted battery casing and re-used. This is about the most environmentally friendly battery technology imaginable, and has functional similarities to cutting edge redox-flow in that “recharge” of an individual unit takes place by simply adding material rather than by plugging in and waiting. This closely resembles the existing petroleum fuel model, and potentially takes “range-anxiety” out of the EV equation.
APET is currently testing a ZOE powered concept car called “The Salamander”, and further refining the technology in an effort to bring it to market. If they are successful in their efforts, a revolutionary new paradigm for EV cost, refueling and infrastructure may alter the way electric vehicles everywhere are going to operate.

there are some chemical formula similar to what you are trying to achieve but the is no details on volatility.

Since KMNO4 is a strong oxidizer there is a chance that when the Acrylic starts to set it might self ignite due to the oxidized accelerating of the chemical reaction.

I have never made the formula you are trying to achieve so I would make a very small sample first, test it for impact ignition, self ignition, and fire ignition, spark ignition. just to play it safe.

KMNO4 and sugar will self ignite if handled improperly. KMNO4 & KOH & Sugar will self ignite whether handled or not. be very careful.

try to keep the solution well ventilated incase there is a gas reaction on top of any other reaction present.
