Gel battery, that is to say, once the tab of the battery cell is completed, a layer of gel approximately 10 µm thick is applied to the surface of positive and negative electrodes.ElectrolyteThe other processes are similar to those of ordinary electrolyte system cells.
The advantage of gel batteries is that they have good safety performance, but their high-rate charging and discharging performance is not good because lithium ions have a limited mobility in the gel electrolyte.
Classification
Lithium polymer batteries can be divided into three categories according to the electrolyte:
1. Lithium-ion battery with gel polymer electrolyte, which is made of solid. Polymer additives are added to the physical electrolyte to increase ionic conductivity, so that the battery can be used at room temperature;
2. Beatie lithium-ion to solid polymer electrolyte, the electrolyte is a mixture of polymer and salt, the ionic conductivity at room temperature Low efficiency, suitable for high temperature use;
3. Lithium-ion batteries with polymer gel composite cathode materials are used as cathode materials, and their specific energy. is three times higher than that of existing lithium-ion batteries. The latest generation of lithium-ion batteries.

The impact of the quality of batteries used in car emergency starting power supplies Power supply brand 12V car emergency start OEM/ODM Manufacturer - Grep Car Battery The influence of the quality of the battery cells used in the emergency start power supply
The car must have enough power to start. To provide sufficient power, the power supplyThe car's emergency starting system must provide emergency starting power. Sufficient current to be able to start the car better. Most of the batteries used in today's portable emergency starting power supplies are lithium batteries, and they are high-rate batteries that can withstand high-current, high-rate discharges. These lithium batteries are mainly divided into high rate lithium polymer batteries and high rate batteries. -lithium iron phosphate batteries. There are two types. Due to the difference in the manufacturing process level and R&D technology level of battery cell manufacturers, the quality of battery cells will be different. Power supply, but also affects the service life. For example, if a poor quality battery cell starts the car several times or after using it for asome time, it will obviously feel weak when starting, that is, it will not be able to provide enough current to support starting the car. will always make people frustrated.
The impact of the quality of electronic components on the circuit board of the car emergency starting power supply
The electronic components of the circuit board of the car emergency start power supply Car emergency start are an important key to protecting the battery core, and they also effectively implement other accessory core functions, so it is also crucial. Due to the voltage difference, capacity difference, internal resistance difference and other factors in the battery core, the balanced adjustment capabilities of the circuit protection and charging protection board and the discharge of the battery core directly affects the life of the bat corerie, i.e. the lifespan of the emergency power supply. Of course, the circuit design has high scientific precision and low power consumption, which is also an important guarantee for the realization of other accessory functions. To sum it up, it's about whether the experience of using the emergency start power supply is good or not.
The internal factors mentioned above determine whether a car's emergency starting power supply is good or not. Below we will do it intuitively. Let's briefly talk about how to choose and buy car emergency starting power according to use experience.
1. The feeling of starting the car is the same when it is fully charged and when it is not fully charged (i.e. when the capacity is 20% or more), i.e. -say the feeling of strong powert the same;
2. The car can be started within a certain wide temperature range, such as -20℃~60℃. The car can be started easily;
3. The average power consumption of the number of starts of the car is almost the same, that is, the current consumed by each start is almost the same;
4. Starting a car uses energy relatively slowly. For example, with the same capacity, the more it can be started, the better;
5. Small self-discharge means that the self-consumption of energy is low when we don't use it, which is generally better;
6. After being used for a while, power consumption accelerates significantly, which is usually the case with the battery. The quality of the core is not good, the capacity is aging, the internal resistance is increased, the energy is consumed quickly, and it is easy to heat;

< h3>How to start a vcar with a magnifying batteryAngjia automobile emergency starting power.
Angjia car emergency starting power supply is lithium polymer batteries are currently a popular automobile emergency starting power source and enjoy a good reputation in all respects. In China, Angjia is one of the first manufacturers to launch 80C continuous discharge lithium polymer batteries. Commodity performance indicators have been achieved. the advanced level at home and abroad.
Key points for purchasing emergency starting power supply:
Battery capacity: It is recommended to choose according to your needs. If it's not a very large car, approx. 10,000 mAh is enough. Some car owners need to integrate it as a mobile power supply, but the capacity is too large and is not suitable. Neckpeak current, starting current: The purpose of backup power is to release a large amount of electricity in an instant to activate the battery. Generally, the more cells there are, the greater the current released. Cars are usually equipped with a 60 Ah battery, and the starting current is usually between over 100 and 300 amps. However, if the motor has a larger displacement, the starting current will be greater. Some products also have a “0 voltage” start function. Simply choose the one that suits your vehicle's engine size and needs. Output voltage and interface: Common output voltages are 5V and 9V, and some products also include 12V DC voltage. The interfaces mainly include USB, Type C and DC interfaces. There are also products that support fast charging protocols. The more interface you haveaces and types, plus it can be used to charge cell phones, laptops or other electronic products. It can even be connected to other 220V electrical appliances via an inverter, making usage scenarios richer. Lifespan: Typically, products are designed for several thousand cycles. Regular household use certainly won't reach this limit, so don't worry too much. Lighting function: It is better to have a lighting function, so you don't have to worry about using it at night or in dark scenes. It's best to have SOS emergency lights. Electric Clamp: Mainly depends on the quality of wire and battery clamp. The wire should preferably be made of soft silicone insulation (AWG). The copper material of the clip must be thick enough to withstand large currents. high temperatures. He musthave certain protective functions.For example, many brands claim eight protections: overload, reverse charge, overcurrent, short circuit, reverse connection, overheat, overvoltage, overload, etc. If the connection is accidentally reversed, a beep or light alarm will sound to prevent damage to the vehicle and the starting power itself. There is also an anti-rollback interface designed to provide more convenience for novices. Operating temperature: Northern friends should focus on the discharge temperature. For example, -20℃ can basically meet the needs of most areas in northern China. Reasonable use within the operating temperature range can better extend the life of the tool. Power Display: Since this type of tool is used less frequently, there will be some loss of power if left idle for a llong period. It will be more clear if you can accurately see the remaining battery power or the working interface. However, the LCD digital display is not necessarily more reliable than the power level, and it is doubtful whether it can operate normally in low temperature environments. Price: The quality of the brand you choose is guaranteed. I looked at the pages of several popular products and they all have relevant certification and quality testing reports. However, each company's molds, chip solutions, battery structures and functions are different, including brand premiums, so you can choose according to your own needs. Others: such as waterproof caps, compasses, etc. It depends if you need it. The battery of some models is a little long, so you need to consider whether the battery cable is longer. Function and sizee: Under normal vehicle conditions, there are relatively few opportunities to use the emergency power supply. Therefore, adding new features can also increase the frequency of use of these products. For example, it can be used to charge tablets and mobile phones, and to ignite motorcycles and even yachts. The most important thing is that the size is small enough while ensuring product safety! It can even be put in women's handbags, making it more versatile!
