36 volt industrial battery

　Industrial lithium batteries in practical applications, may encounter a series of common problems, which are mainly related to the performance, safety, life and other aspects of the battery. Here are some common problems and their brief analysis:

一. Performance problems

Capacity decay:

Description of the problem: With the growth of the use of time, the capacity of lithium batteries will gradually decline, that is, the battery can store less power.

Cause analysis: This may be due to the deactivation of battery materials, damage to the battery structure and the gradual weakening of the chemical reaction within the battery.

Increase in internal resistance:

Problem Description: The internal resistance of a battery is the resistance encountered when current passes through the battery, and an increase in internal resistance will affect the charging and discharging efficiency of the battery.

Cause analysis: The increase of internal resistance is usually related to the aging of the battery, the deterioration of the electrolyte and the decrease of the activity of the electrode material.

二、safety issues

Battery internal short circuit:

Problem description: Direct contact or non-normal conductivity occurs between the positive and negative electrodes inside the battery, resulting in current distortion and energy loss.

Cause analysis: This may be caused by uneven distribution of materials, external metal contamination, poor welding and other reasons. Internal short-circuiting may trigger serious consequences such as heating, smoking or even explosion of the battery.

Electrolyte leakage:

Problem description: Electrolyte is the medium substance for transferring ions between positive and negative electrodes inside the lithium battery, if the electrolyte leaks, it will lead to the decrease of battery capacity, energy loss, and even cause spontaneous combustion and explosion of the battery.

Cause analysis: Electrolyte leakage may be caused by insufficient sealing of the battery, external physical damage and other reasons.

Overheating, overcharging and over-discharging:

Problem description: Industrial lithium batteries generate heat due to redox reaction during long time usage. Poor heat dissipation or improper charging/discharging control may lead to overheating, overcharging or over-discharging of the battery.

Cause analysis: overheating may trigger the acceleration of the internal chemical reaction of the battery, leading to battery damage or even explosion; overcharging and over-discharging may damage the battery structure and shorten the battery life.

三、the life of the problem

Battery aging:

Problem description: With the growth of the use of time, lithium batteries will appear electrochemical performance degradation, such as capacity degradation, internal resistance increase, etc., these are the performance of battery aging.

Cause analysis: Battery aging is due to the aging of battery materials, structural damage and the gradual weakening of the chemical reaction of a variety of factors such as the result of joint action.

Other Problems

High cost:

Description of the problem: Industrial lithium batteries due to the complex manufacturing process, high material costs and other reasons, resulting in its relatively high cost.

Reason analysis: This is mainly due to the lithium battery in the production process requires the use of high-precision, high-demand process and equipment, as well as the use of high-purity, high-reliability materials caused by.

Management is complicated:

Problem description: Industrial lithium batteries need to be monitored and managed in a unified way using a professional battery management system to ensure the safety and life of the battery.

Cause analysis: Battery management system needs to monitor the battery's voltage, current, temperature and other parameters in real time, and adjust the charging/discharging strategy according to these parameters to ensure the safety and performance of the battery. This increases the complexity and cost of the system.
