Lithium Battery Customization Tips You Should Know

How to customize the lithium battery pack, what should be paid attention to when customizing the lithium battery? Lithium battery packs are becoming more and more refined in different fields, such as consumer lithium batteries, industrial lithium batteries, communication lithium batteries, power lithium batteries, and energy storage lithium batteries. The needs of the product are different, so the performance of the corresponding lithium battery will also be very different. What are the precautions for the need for a custom lithium battery pack?

Custom lithium battery pack time cycle

We can provide a quick sample service. The entire cycle of custom lithium battery pack process is usually within 15 working days.

The first day: Evaluate and discuss the requirements of the customer, and then make a quotation for the sample. After both parties have negotiated the price, they will customize the product. The second day: the selection of the product cell and the design of the circuit structure. Day Three: Samples will be made long after the design is complete. Day 4: Initial test and debugging of functions are completed. Day 5: Perform the electrical performance and cycle aging test verification of the lithium battery pack. Day 6: Packaging for safety test and launch. The whole process of lithium battery is completed in 15 minutes.

Custom parameters for lithium battery customization

1. Make sure the input and output ports of the lithium battery are somehow.

2. It is necessary to confirm the IP protection level of the lithium battery pack and the fixing method of the battery pack, and also consider how to install the lithium battery pack, which will have a great effect on the design of the lithium battery.

3. The size of the space for the lithium battery. This will affect the capacity of the supporting lithium battery pack. It is best to communicate with the lithium battery manufacturer before ordering the lithium battery, so as not to cause a great difference between the ideal and reality. The situation occurred.

4. What needs to be known in advance is the life expectancy of customized lithium batteries. The life of iron lithium batteries is generally 2,000 cycles.

5. You need to know how long the device will continue to work because it will determine the capacity of the lithium battery pack that needs to be ordered.

6. For devices with similar motors, when supporting lithium batteries, you need to know the instantaneous maximum power when starting these inductive loads.

7. Because the voltage of the lithium battery pack is not a fixed value and has a wide range, it is necessary to ensure that the device can withstand the corresponding voltage value.

8. Determine the size and shape of the battery, so that lithium battery manufacturers can reduce the scope when developing and designing.  Grepow lithium polymer batteries can be designed and manufactured in a variety of shapes depending on the device, including round batteries, curved batteries, ultra-thin batteries and so on. If you ask, I will give you what you want!

Lithium battery customization

1) Custom-made mass-produced products for lithium battery packs are independently developed and designed for different products, so during the customization process, certain costs need to be paid (generally involving mold opening costs, development costs, and product proofing cost Wait).

2) R & D time: The length of the R & D time is directly related to the new time on the product. The general R & D time for custom lithium battery packs is about 30 days, and the fast R & D channel is implemented. Generally, the proofing time of products that do not require mold opening can be reduced to 15 days.

As an emerging industry, lithium batteries have developed rapidly in the past two years, and more and more companies have applied lithium battery packs to their products. A custom lithium battery pack came into being in this environment.

Key Considerations for Custom Curved Batteries You Should Know

Basic properties of a custom curved battery

Basic information on curved battery

What is a curved battery?

The curved battery mainly refers to the polymer curved battery, which is a kind of polymer battery. It has a curved state during the lithium battery manufacturing and molding process, and the finished product is generally seen with the arc. So most people call it a polymer curved battery.

With ultra-thin features

Another characteristic of the curved battery is that it is thinner. It is two-thirds thinner than ordinary polymer lithium batteries. The thickness can be as thin as the thickness of the card battery (Grepow ultra-thin battery can achieve 0.4mm thickness, thinner than the card）but changes in shape.

Application of curved battery

The battery capital thinks that it is the most prominent among common consumer electronics products, like smart bracelets, ultra-thin waterproof bracelets, electronic keys, Bluetooth headsets, curved electronics Most of the above devices are powered by this curved lithium battery.

The basic performance of the custom curved battery

Different types of curved arc batteries can be customized according to requirements.

Curved battery rated voltage: 4.35V.

Charge and discharge voltage: 3.0 ~ 4.4V.

Charging temperature: 0 ° C ~ + 45 ° C.

Discharge temperature: -20 ° C ~ + 60 ° C.

Storage temperature: -10 ° C ~ + 45 ° C.

standard charge: 0.2C, maximum charge: 2C.

Standard charging method: 0.2C CC (constant current) charge to 4.4V, then CV (constant voltage 4.4V) charge until charging current ≤0.05C, maximum discharge current: 2C.

curved battery weight: between about 4g ~ 10g.

If the curved battery is subjected to secondary finished product PACK, then it is necessary to add protection plates, wires, insulation materials, and other methods to the battery to assemble, and 100% finished product testing, so as to ensure that the yield is improved during use. If you can contact us at [email protected], we will tailor your products and ensure the safety and reliability of lithium batteries.

Includes temperature range at temperature -50 ℃~50 ℃ or 20 ℃~80 ℃, capacity, rate, etc. Grepow can provide integrated power solutions according to customer requirements. If you need anything different from this parameter, please send us more details for the evaluation.

The process of a custom curved battery

Customized battery specific requirements

Because the curved battery is also called polymer curved arc lithium battery, because it is made using a polymer solution, the appearance packaging is aluminum plastic film packaging, where to make curved arc lithium batteries, please propose Your specific use of the battery, the use environment, charge and discharge specifications, finished product size requirements, voltage capacity, and other needs, our engineers will evaluate the feasibility of the solution according to your lithium battery customization needs, and then issue the corresponding technical information.

Guess how many degrees does this curved battery bend?

Guess how many degrees the polymer curved battery above is bent. Most people really can’t guess exactly, suggesting that the degree of bending is less than 180 degrees.

The dimensions of the Grepow curved battery as bellow:

Cost of mold

We already have molds for some battery models that can be produced directly. But for the new model, the curved battery needs to be opened during the manufacturing process, which will involve the mold cost. In addition, the arc lithium battery is poor inconsistency during the production process. The yield rate is lower than that of other cylindrical 18650 lithium batteries. In terms of price, it is also higher than ordinary polymer batteries. You must be aware of this. Since portable suitcase energy storage batteries are used more outdoors, we will propose a system usage specification. Please refer to our battery use specifications for correct use.

Apple Smart Ring- Real Life Lord of the Rings!

Apple media Appleinsider reported that Apple may be developing the next wearable device – Apple Smart Ring. It may have some of the features of the smartwatch Apple Watch that can manipulate nearby wireless devices.

The US Patent and Trademark Office certified Apple’s patent, called the “device, method and user interface for wearable electronic rings.” According to patent data, the smart ring consists of a processor, a wireless transceiver, a power supply, and a microphone. It also includes other sensors that replace the user’s gestures, as well as the dial of the Digital Crown of the Apple Watch.

The tactile actuator inside the ring can provide force feedback and “communication direction information” to the user; the motion sensor can sense the writing action; the biosensor can track the health data; the wristband also supports NFC communication, and the identity can be connected via the wireless connection. The information is transmitted to the second device, and some are used to unlock the Mac.

Apple Ring Demo Picture Source: Apple Patent Report

Apple-defined gestures include pointing a finger with a ring to another device for a wireless connection, or a swipe or flick gesture to change the selection in the menu, and rotating the finger to indicate the rotation of the device screen, and so on. When the user touches or taps the surface, it vibrates slightly, giving the user force feedback.

Like the Apple Watch, Apple may also define it as an auxiliary health product. Because the multiple transmitters included in the device allow for more accurate motion detection. In addition, it also has a touch screen that supports text input methods similar to Apple Watch.

Apple submits a large number of patent applications every week. Not all concepts are completely converted into final products, but Appleinsider believes that it does indicate the areas of interest that Apple is researching and developing.

Earlier in 2015, Apple submitted a patent application saying it was developing a wearable smart device smaller than the Apple Watch, called the “Apple Ring.” The user can wear a ring with a touch display on the index finger and intervene with the thumb.

For Apple, the pursuit of smaller and lighter wearable devices is a reasonable trend. Although Apple Watch is considered a successful work, there are still many people who prefer mechanical watches and think it should be embarrassing. Naturally, if a smart ring can achieve the same effect in a more inconspicuous way. However, from the current patent picture, it seems that this ring is not too good-looking – at least similar to the traditional ring.

In addition, it is worth mentioning that Apple is not the only big technology company that is developing smart rings. Amazon recently also launched a smart ring called Echo Loop, which has two microphones that can be activated by pressing a button. When you need to connect to Alexa, you still need to rely on another separate host device for behavior processing and Data Connections.
