LTO Battery Aluminum Case For EV
The LTO battery aluminum case for EVs is a precision structural component designed specifically for power batteries in new energy vehicles, energy storage systems, and high-reliability lithium battery modules. As a critical element of prismatic lithium batteries, the aluminum alloy casing not only secures the battery cells and provides mechanical protection and environmental isolation but also influences the system's thermal dissipation efficiency, structural stability, and long-term operational reliability. Manufactured using high-performance aluminum alloys and processes such as stamping, deep drawing, precision welding, CNC machining, and surface treatment, the product meets the stringent requirements of global new energy battery manufacturers regarding lightweight design, high consistency, and long-term stability.

Product Introduction
This product consists of an aluminum alloy casing and cover plate assembly designed for prismatic power battery cells. Its typical components include:
Casing (Can): An open-ended rectangular box formed from aluminum sheet via multiple deep-drawing steps; it houses the cell core (wound or stacked) and electrolyte, while containing internal pressure.
Cover Plate (Top Plate/Lid): Integrates terminal posts, an explosion-proof valve (rupture disc), a fill port, and sealing structures; it serves as the critical interface for pressure relief and electrical conduction.
Sealing and Insulation Components: Sealing rings, insulating films, and gaskets; these isolate the terminal posts from the cover plate to prevent surface leakage and electrolyte seepage.
Optional Surface Treatment: Insulating coating or anodized layer on the outer casing wall to meet requirements for module-level lateral insulation and scratch resistance.
The complete assembly is supplied as a matched set based on the customer's cell specifications, ensuring dimensional integrity and preventing interference during the core insertion and sealing processes.
Technical Features for Prismatic Aluminum Case Power Battery
Customized Structure
External dimensions, height, wall thickness, terminal positions, explosion-proof valve location, and electrolyte fill-port layout are all custom-developed to meet specific customer cell specifications.
01
Integrated Cover Assembly
Cover assemblies can be supplied as a complete unit-integrating components such as terminals, explosion-proof valves, and fill-port plugs-thereby reducing the coordination risks associated with multi-source procurement.
02
Explosion-Proof Safety Design
The explosion-proof valve features sensitive activation and reliable sealing, providing a final line of pressure-relief protection during abnormal cell operating conditions.
03
Corrosion-Resistant System
Surface treatment solutions are selected specifically for electrolyte exposure and long-term hot-and-humid operating conditions, effectively inhibiting casing pitting and surface degradation.
04
Lightweight Design
Wall thickness distribution is optimized while maintaining structural safety margins, supporting vehicle-level and battery pack weight-reduction targets.
05
Key Functions and Engineering Value for LiFePo4 Prismatic Battery Aluminum Cells
Structural Support and Safety Protection
The casing withstands internal gas pressure generated by the battery cell, as well as external mechanical impacts and vibration loads. An optimized wall thickness design and reinforcement rib layout ensure sufficient structural rigidity while maintaining a lightweight profile.
Thermal Management Interface
The high thermal conductivity of the aluminum casing enables efficient heat transfer from the cell interior to the external cooling system. The surface quality of the casing directly impacts the interfacial thermal resistance between the casing and the liquid cooling plate or thermal interface material.
Sealing Barrier
The fully sealed structure, formed via laser welding, isolates the cell from external moisture and air while preventing electrolyte leakage. The long-term reliability of this sealing structure is fundamental to maintaining the performance of LTO batteries under demanding operating conditions, such as wide temperature ranges and frequent fast charging.
