Regarding the application of lithium-ion batteries, this is a never-ending study and research. From the numerous application fields in the current market, combined with manufacturing experience, we classify lithium batteries into normal, high-temperature, low-temperature, high rate, and power batteries. 5 categories can be as following: 1. Normal battery.Tablet PC, mobile power supply, digital devices, Bluetooth …
You probaly noticed that lithium batteries becomes popular since ever. Now I write the behind logic for you. The batteries have high voltage and light weight. The average voltage of a single battery can reach 3.7V or 3.2V. It is relatively equal to the series voltage of 2-4 nickel-hydrogen batteries or nickel-isolated ones. If the customer …

Function introduction of the main parts of the protection board R1: Reference power supply resistance; forms a voltage divider circuit with the internal resistance of the IC to control the level inversion of the internal overcharge and overdischarge voltage comparator. Generally the resistance value is 330Ω and 470Ω. When the package form (that is, the …
1. The composition of the protection board of lithium battery Its characteristics determine the reason why lithium battery (rechargeable) needs protection. The lithium battery material itself determines that it is not allowed over-charged, over-discharged, overcurrent, short-circuited. The lithium battery’s ultra-high temperature charging and discharging lithium battery components will always appear with an exquisite protection board …

At present, all types of consumer electronics, mobile power supplies, and new energy vehicles represented by mobile phones use lithium battery devices. Lithium battery is the direction of new energy development in the future. Recently, some electronics factories have caught fires and explosions. The safety of lithium batteries has become the most concerned issue of …
This post will discuss the advantages and disadvantages of the lithium-ion battery. Advantages of lithium-ion battery High voltage: The single battery’s working voltage is as high as 3.7-3.8V (the cell voltage can be up to 4.2V). That is three times that of Ni-Cd and Ni-H batteries. Enormous specific energy: The actual specific power that can …

The lithium battery is a kind of energy storage conversion device. Because of its excellent electrochemical performance, it realizes a different market application scenario. When we talk about lithium batteries, it usually refers to small applications, namely consumer electronics. Its working principle is charging to store energy. And discharging is converted into other energy and …
Today, I will write about the lithium battery aging. Aging is to load and run the product under a certain temperature and/or load. And then check whether the product’s performance indicators meet the technical requirements after a period of time. Lithium-ion battery aging generally refers to the placement of the battery after the first charging …
