How does Li-ion Battery Manufacturer Ensure Safety in Design & Manufacturing?

2025-05-13

Lithium-ion (Li-ion) battery manufacturers implement multiple safety measures during design and manufacturing to prevent hazards like thermal runaway, fires, or explosions. These measures span material selection, cell design, production processes, and quality control. 


1. Safety in Battery Design

A. Cell-Level Safety

LN Energy Tech cooperate with reliable battery cell factories and supply directly from the original factory to ensure grade A quality.Like Samsung,LG,LISHEN,BAK,EVE,DMEGC;


B. Battery Pack-Level Safety

Protection Circuits (BMS – Battery Management System)Monitors voltage, current, and temperature to prevent overcharge/discharge.Balances cell voltages to avoid uneven stress.


C.Battery Case design-Level Safety

According to different usage scenarios, the battery pack structure and external shell design adopt hard materials and waterproof structures to reduce battery failure problems caused by external collisions and water ingress.


2. Safety in Manufacturing Processes

A. Controlled Production Environment(Temperature and humidity control)

B. Precision Assembly(Use fully automatic and semi-automatic production equipment)

C. Test process control(Seven inspection checkpoints control quality and safety)

D.Aging Tests(100% product aging)
