Advantages and disadvantages of ternary composites for lithium batteries

Ternary materials are considered ideal raw materials for lithium batteries because of their low cost and stability.lithium ion battery VS lead acid battery There are many advantages of lithium batteries with ternary materials as the positive electrode. Next, we will introduce the advantages and disadvantages of ternary lithium batteries in detail to help you better use lithium batteries.

Positive electrode ternary lithium batteries use traditional artificial intelligence synthesis of high-purity graphite and other excellent battery material technology as the negative electrode. Stacked built-in plastic flexible packaging processing production process development makes the battery system internal control current distribution is uniform, heat dissipation performance has good, improve the battery multiplier characteristics.

The invention solves the patent problem of ternary lithium battery diaphragm and improves its own safety performance. Safety evaluation experiments such as drop-in, extrusion molding, sticky pins, hot box, overcharge, etc. have been conducted on single cell batteries and modules.

The unique diaphragm material increases the volume of diaphragm liquid, increases the pore space and reduces the internal resistance of the battery. lithium battery vs lead acid Charging and discharging depth is 80% of DOD when charging with 1x current. After 3,000 cycles, the capacity is still maintained at over 85%.

The weight of 25Ah power lithium battery for energy distribution density is 160Wh/kg, which is more than 30% higher than the weight of lithium iron phosphate battery, which can improve as well as range by reducing the weight of the whole vehicle structure of the enterprise.

In the case of high-current charging, polarization is small, and the temperature rises. Battery can be continuously 3C charging, 4C discharging (instantaneous discharge 10C), with high I/O capacity.

Effective Li-ion battery electrolyte formula and formulation make the Li-ion ternary battery discharge in the range of -20~45C and charge in the range of 0~45C.

The reliability of the battery is also good. This product can be used through a variety of research and invention design patents, powder pretreatment information technology, to ensure that the powder and slurry for mixing uniformity; unique curing process quality assurance of the stability of the ternary lithium battery emulsion.

However, lithium-ion batteries have some disadvantages.

Low safety and low cycle life are the main weaknesses of Li-ion ternary batteries, especially safety, which is a key factor limiting their large-scale assembly and mass integration applications. Test results show that large-capacity Li-ion batteries cannot be tested for safety by pin-prick and overcharge methods, which is why large-capacity Li-ion batteries usually require the introduction of large amounts of manganese, or even mixed lithium manganate batteries. The cycle life of Li-ion battery is 500 times, which belongs to the lower middle level. Therefore, the main application field of Li-ion ternary battery is consumer electronic equipment, such as 3C digital technology.
