Custom lithium-ion battery packs are designed to your unique specifications and can be built to function to the exact specifications of your project. Custom portable lithium battery packs provide the power and custom solutions your application needs to perform at its fullest.
The main cause of safety hazards such as lithium-ion fire is the imbalance of the cells. In view of the imbalance between the cells in the charging and discharging process of the lithium-ion battery pack, based on the best priority idea, a new balance strategy for lithium-ion battery packs is proposed. .
This strategy analyzes the change law of the two key characteristic factors of lithium battery cell voltage and capacity, based on the best priority idea, determines its comprehensive influence degree, seeks the best path of balance, and realizes the charging, discharging, and shelving of lithium batteries in different states. The balanced adjustment of the lithium-ion battery can achieve the goal of balanced adjustment of the lithium-ion battery pack and provide a guarantee for the reliable energy supply of the lithium-ion battery. Our design implementation strategy can include:
Because of its high energy, high battery voltage, wide operating temperature range, and long storage life, lithium-ion batteries are widely used in energy storage power systems such as water power, thermal power, wind power and solar power plants.
Uninterruptible power supply for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. And with its unique performance advantages, it has been widely used in portable appliances such as laptop computers, cameras, and mobile communications.
As mentioned above, the range of application equipment for custom lithium batteries is very wide.7.4V lithium battery pack is a multi-series and multi-parallel lithium battery pack, which is widely used in notebook batteries, LED flashlights, digital cameras, manufacturers of miner’s lamps, medical equipment, emergency lights, etc., can play a very good role in protecting electrical appliances. high energy density, high voltage, no pollution, no metal lithium, high cycle life, no memory effect, fast charging.

High working voltage
Using carbonaceous lithium intercalation compounds such as graphite or petroleum coke instead of metal lithium as the negative electrode will reduce the battery voltage. However, due to their low lithium intercalation potential, the voltage loss can be minimized. At the same time, selecting a suitable lithium intercalation compound as the positive electrode of the battery and selecting an appropriate electrolyte system (determining the electrochemical window of the lithium ion battery pack) can make the lithium ion battery pack have a higher working voltage (-4V), which is much higher than in aqueous system batteries.
High energy density
Higher operating voltage and volumetric specific capacity determine the higher energy density of secondary lithium-ion batteries. Compared with Ni-Cd batteries and Ni-MH batteries, which are widely used at present, secondary lithium-ion batteries have the highest energy density and still have great development potential.
Good safety performance and long cycle life
The reason why the battery using metal lithium as the anode is unsafe is that the structure of the positive electrode of the lithium ion battery changes and the porous dendrite is formed. It can pierce the separator and cause an internal short circuit, and lithium-ion batteries do not have this problem and are very safe.
Low self-discharge rate
The lithium-ion battery pack adopts a non-aqueous electrolyte system, and the lithium-intercalation carbon material is thermodynamically unstable in the non-aqueous electrolyte system. During the first charge and discharge process, a solid electrolyte interphase (SEI) film will be formed on the surface of the carbon negative electrode due to the reduction of the electrolyte, allowing lithium ions to pass through but not electrons, and allowing the electrode active materials of different charge states to pass through. In a relatively stable state, it has a low self-discharge rate.
Clean and pollution-free
Lithium-ion battery packs do not contain toxic substances such as lead, fortune, mercury, etc. At the same time, because the battery must be well sealed, very little gas is released during use, causing no pollution to the environment.
High current efficiency
Unlike any previous secondary batteries with aqueous systems, lithium-ion batteries do not generate gas during normal charge and discharge processes, and the current efficiency is close to 100%, which is particularly suitable for use as batteries for power storage and conversion.
