Soft pack lithium batteries
Soft pack lithium battery safety performance is good, generally will not explode, there will only be bulging or cracking. Secondly, lightweight, the weight is about 20% lighter than aluminum shell batteries. Third, the internal resistance is small, soft pack lithium batteries currently soft pack lithium battery internal resistance has been done to a minimum of 5mΩ below, greatly reducing the battery’s self-consumption of electricity.
Aluminum lithium battery
Battery aluminum shell has a high specific strength, specific modulus, fracture toughness, fatigue strength and corrosion stability. And has the advantages of aluminum alloy, with light weight, molding and durability.
Square Plastic Shell Lithium Battery
The following picture is Thunder Sky Winston Battery plastic shell lithium battery
The battery shell is made of reinforced pp material. The shell has heat spreading grooves, which can effectively dissipate heat for the battery, and the hard shell material can effectively prevent collision and fall.
The following picture shows the excellent thermal performance of the square lithium iron phosphate battery. The infrared photo shows a real example and calculation simulation of high current discharge of prismatic LFP battery.
The advantage of the prismatic LFP is that these cells have a massive block volume (and mass) and the heat is absorbed and distributed equally. The photo shows that even during a high-speed discharge with 2C, the cell does not overheat.
