Description

Technical Field

[0001] This utility model relates to the field of lithium battery packs, specifically a high-temperature resistant lithium battery pack. Background Technology

[0002] A lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. These batteries offer advantages such as high energy density, long lifespan, and low self-discharge, making them widely used in portable electronic devices, electric vehicles, and energy storage systems. The working principle of a lithium-ion battery involves storing and releasing energy through the movement of lithium ions between the positive and negative electrodes. During charging, lithium ions move from the positive electrode to the negative electrode and are stored there; during discharging, lithium ions move from the negative electrode to the positive electrode, releasing energy. Due to its superior performance and broad application prospects, lithium-ion batteries have become an important component of modern battery technology.

[0003] Most existing lithium-ion battery packs are designed and used in applications with open or semi-open structures. This means that when exposed to high temperatures or open flames, the electrolyte and flammable gases inside are prone to leakage and accumulation, increasing the risk of explosion and fire. This design flaw poses a certain safety hazard to lithium-ion battery packs. Utility Model Content
