There are two reasons for the excessive self-discharge of lithium-ion batteries: physical micro short-circuit and chemical reaction.

1. Types of rechargeable batteries: Nickel-cadmium battery (Ni-Cd), Ni-MH battery (Ni-MH), Lithium ion battery (Li-lon), Li-polymer battery (Li-polymer), Lead-acid battery (Sealed) ...

What are the common positive and negative materials in the lithium-ion battery industry? The main constituent materials of lithium-ion batteries include electrolytes, separator materials, and positive and negative electrodes. Cathode materials and anode materials are one of the key materials that determine the performance of lithium-ion batteries, and are also the main source of lithium ions in current commercial lithium-ion batteries. Their performance and valence have a greater impact on lithium-ion batteries.

The voltage of a lithium ion battery is determined by the electrode potential. Voltage, also known as potential difference, is a physical quantity that measures the energy difference of electric charges in an electrostatic field due to different potentials. The electrode potential of lithium ion is about 3V, and the voltage of lithium ion batteries varies with different materials. For example, a general lithium-ion battery has a rated voltage of 3.7V and a full-charge voltage of 4.2V; while a lithium iron phosphate battery has a rated voltage of 3.2V and a full-charge voltage of 3.65V. In other words, the potential difference between the positive electrode and the negative electrode of a lithium-ion battery in practical use cannot exceed 4.2V, which is an element based on material and use safety.

High-rate polymer lithium-ion battery, let's first understand the concept of rate. How to understand the discharge rate? The discharge rate refers to the current value required by the battery to discharge its rated capacity within a specified time. The data value is equal to the multiple of the battery's rated capacity, usually represented by the letter C. Generally speaking, if the C number is greater than 1, it means a high rate. High rate is a relative concept. The larger the C number of a lithium-ion battery, the higher the rate of the battery.

Due to the wide application of lithium batteries in portable electronic products, coupled with the continuous expansion of the demand for lithium batteries in the electronic product market, many large and small lithium battery manufacturers have been born, and which brand of lithium batteries is good has become an electronic product buyers often have to consider issues, because the quality of lithium battery brands will directly affect the competitiveness and survival cycle of their end products in the market and the space for profit.

After years of development, the lithium battery industry has formed a complete industrial chain with a high degree of specialization. Do you know how the lithium battery is made?

The INRUSH PEAK discharge current and continuous discharge current mainly depend on the battery cell. The overcurrent protection of the protection board only sets a safe discharge current parameter for the battery. If the battery works within this safety parameter, no safety will occur. (but if the discharge current exceeds the load current of the cell allowed, it may also shorten the battery cycle life)

Both the camera drone battery and the mobile phone battery are lithium-ion batteries. The drone battery is the source of power for the device and has higher requirements for its safety performance. However, there is a difference between the two. The drone battery has a significant feature compared to the mobile phone battery --- high rate discharge. The drone battery needs a large current to discharge to meet the requirements of the drone in different environments. For example, in aerial photography, if a strong wind is encountered, the battery must be discharged with a large current to ensure the stability of the drone's position. Because of different requirements, the life of the camera drone battery is relatively short.

Different types of batteries have different internal resistances. For the same type of battery, due to the inconsistent internal chemical characteristics, the internal resistance is also different. The internal resistance of the battery is very small, we generally use milliohm units to mean it. Internal resistance is an important technical indicator to measure battery performance. Under normal circumstances, a battery with a small internal resistance has a strong high-current discharge capability, and a battery with a large internal resistance has a weak discharge capability. In terms of the schematic diagram of the discharge circuit, we can dissect the battery and the internal resistance and divide it into a power supply with no internal resistance connected in series with a small resistance......
