Flow Battery: Redefining Electric Vehicles
A flow battery is a recyclable battery that exchanges ions by two liquids with opposite charges (electrolytes) and then directly converts the chemical energy into electrical energy.

When it comes to electric vehicles, everyone’s first reaction must be Tesla. Indeed, in many people's minds, Tesla is synonymous with electric cars. But now, there is a car that may have the strength to compete with Tesla - the electric concept car from the Liechtenstein-based nanoFLOWCELL AG - Quant e-Sportlimousine. Not only does it have a beautiful shape, but the car is even more fascinating is its extraordinary "heart" - a new power system with flow battery technology - nanoFLOWCELL.
How powerful is the flow battery? The car has a cruising capacity of 600 kilometers, which is no less than Tesla. At the same time, the power is very strong. In the laboratory, the simulation shows that the acceleration of 100 kilometers is an amazing 2.8 seconds and the top speed is 380 kilometers per hour.
So what exactly is a flow battery? It is a recyclable battery that exchanges ions through two liquids with opposite charges (electrolytes) and then directly converts the chemical energy into electrical energy. The flow battery can generate 0.795 watts per square centimeter of electricity, which is three times that of other thin-film battery design systems and 10 times that of ordinary lithium batteries. In addition, the flow battery has many advantages: it can be idle for a long time without losing the charge, the response time is fast, and the battery can be quickly charged and discharged by replacing the electrolyte.
However, the reason for limiting the development of flow batteries is also obvious: there is usually a film in the battery to separate the electrolytes, and the two liquids are not mixed when they exchange ions. But the problem is that low-cost electrolytes have to erode expensive films, which has led to a significant reduction in battery life. So the best way to extend battery life is to remove the film directly.
The Massachusetts Institute of Technology has made outstanding contributions to the development of flow batteries. In order to keep the two liquids from mixing together, the researchers used a layer flow technique in liquid fluid dynamics to place them in a container. The storage of the electrolyte is separate from the battery itself, and the two tanks are respectively filled with electrolyte. This means that the size of the battery can be easily controlled, and the size of the battery can be changed by changing the size of the slot.
The nanoFLOWCELL system uses a larger battery compartment, which means a higher energy density, with a specific value of 600 watt-hours/kg. At 600V rated voltage and 50A rated current, the system can continuously output a maximum power of 30 kW. Compared to the lithium-ion battery technology that powers today's electric vehicles, the performance is four times higher, which means that its mileage is five times that of conventional components of the same weight. The company also stated that its flow battery can produce no significant memory effects after 10,000 cycles of charge and discharge.
"We don't just want to transform the car, but we also hope to use the flow battery in the fields of shipping, railway, aviation, etc. in the future," said a person from nanoFLOWCELL AG.
Electric dc motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A electric Dc Motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small electric dc motor are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger electric dc motor are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Areas of application: the Electric Dc Motor rotor part of the armature iron core, armature, commutator, such as equipment, electric dc motor is suitable for most electronic products, such as electric screwdriver, laser, smart home, gas valve, etc
Applications:
Method of use: the best stable in horizontal plane, installed on theelectric dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the electric dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Electric dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a electric dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Electric dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
