What are the differences between hard-case and soft-case lithium-ion batteries?

Hello, DeVos Lithium Battery will help you answer!

Mainly refers to the material of the lithium battery shell. If there is packaging outside, it is not easy to see the battery body. The weight of steel shell battery will be heavier. than the battery of the same volume, but the aluminum shell It is not easy to distinguish between shells and soft batteries, but soft batteries are softer than aluminum shell batteries and are easily deformed when they are broken by hand (do not try randomly);

Advantages of soft batteries

1. Good safety performance

The soft battery is structurally packaged with aluminum-plastic film. In the event of a safety hazard, the soft battery will only swell and crack, unlike the steel shell and aluminum shell. The battery cells will explode.

2. Light

Lhe flexible batteries are 40% lighter than steel-cased lithium batteries of the same capacity and 20% lighter than aluminum-cased batteries.

3. Large capacity

The capacity of flexible batteries is 10-15% higher than that of steel shell batteries of the same size, and 5-10% higher than that of steel shell batteries of the same size. that of aluminum shell batteries.

4. Small internal resistance

The internal resistance of soft-pack batteries is lower than that of lithium batteries. Currently, the minimum internal resistance of soft-pack battery cells can be achieved. be less than 35 mΩ, which significantly reduces the battery's self-consumption of energy.

5. Flexible design

The shape of the flexible battery can be customized according to customer needs, and new cell models can be developed.

Disadvantages of batsflexible batteries

The existing models of flexible battery cells are few and cannot meet the market demand;

The development cost of new models is high.

It can be used, but it is unlikely to explode.

Because this situation will have no impact on the battery, let alone the risk of explosion. Generally, the battery has overcurrent and overvoltage protection, and there will be no explosion even if it. is used, it will swell, commonly known as It will not explode even if it has a “big belly”? This is because batteries generally have a safety pressure design and will be protected if the internal pressure or temperature exceeds a certain level.

Cell phone batteries are energy storage tools that power cell phones. They consist of three parts: battery cells, circuitryprotection and housings. Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries.

Charging method:

1. Current mobile phone batteries are all lithium-ion batteries (often called lithium batteries in non-standard situations), and the positive electrode material is lithium. cobalt oxide. The standard discharge voltage is 3.7 V, the charging cut-off voltage is 4.2 V, and the discharge cut-off voltage is 2.75 V. The unit of power is Wh (Watt-hour ). Since the standard discharge voltage of mobile phone batteries is uniformly 3.7V, it can also be replaced by mAh (Milliamp-hour). The conversion relationship between these two types of units on cell phone batteries is: Watt-hour = Ampere-hour × 3.7.

2. Overcharging, overdischarging and short circuits inwill seriously damage battery performance and may cause operating hazards. For this reason, cell phone batteries usually have a thin protective circuit board to prevent these risks.

3. Loaders are divided into direct loaders and seat loaders. Direct charging converts 220 AC mains power into 5V DC, feeds it into the mobile phone, and is lowered by the mobile phone's charging circuit to be used by the battery. Generally, delivery will be made when you purchase a mobile phone. The charger is directly connected to the battery and converts the mains power into the required voltage for the battery to use.

4. If you want to use a charger, try to choose original or high-quality products. If the base charging circuit is of poor quality, there will be charging risks.

5. Lith batteriesium-ion do not have a memory effect, but are inert if not used for a long time they can become passivated. They can regain their best performance by rinsing them several times.

6. Lithium batteries do not need to be specially discharged before charging. Some fast chargers only indicate 90% full charge when the light changes, and the charger automatically switches to trickle charging to fully charge the battery. But generally speaking, as long as it shows full, it can be removed.

7. In order not to damage the battery life, it is best to charge slowly when charging; the time should not be too long.

8. There is self-discharge in cell phone batteries because over-discharging will damage the battery. If the cell phone battery is not used for a long time, it is suitableto make sure it is properly charged. certain amount of power.

9. Although our mobile phone is within the network coverage area, our mobile phone is no longer able to receive and make calls when it is turned off and charging. At present, we can use the missed call forwarding function of the mobile phone to transfer the mobile phone to the landline around us to avoid the loss of incoming calls. This method is also applicable when the mobile phone is not within network coverage. area where the signal is weak and cannot be connected temporarily.

10. Do not expose the battery to high temperatures or intense cold. For example, during summer days you should not leave your cell phone in the car to expose it to the scorching sun; Take it to an air-conditioned room and place it where the air conditioner blows directly. During the cHowever, it is normal for the battery to be a little hot, but it should not withstand the “suffering” of high temperatures. To prevent this from happening, it's best to charge at room temperature and not cover the phone with anything.

11. The longer the charging time, the better. For lower quality batteries without protection circuits, charging should be stopped once they are fully charged. If not used for a long time, the battery should be separated from the mobile phone.

12. The newly purchased battery does not need to be charged for 12 hours for the first time, but it is better to complete a full charge and discharge process for 3-5 hours. 100% normally, and full discharge means the mobile phone uses low power when recalled. Because the battery must go through filling, training, chargingand electrolyte discharge, capacity sharing and other processes before leaving the factory, so that the battery is in an activated state. However, after leaving the factory, it takes at least one month. a year before it can reach the user's hands. Because the battery is automatically due to the influence of discharge, the battery material becomes passivated at this time, the battery can be activated by full charge and discharge.

What should be noted when using lithium batteries is that the battery enters a dormant state after being left for a period of time. At that time, the capacity is lower than the normal value and the usage time is also lower. shortcut. However, lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity. Due to the characteristics ofthe lithium battery itself, it has almost no memory effect. Therefore, the user's new mobile phone lithium battery does not require special methods and equipment during the activation process. Not only is this true in theory, but from my own practice, this "natural activation" method of loading using standard methods from the start is the best.
