The 48V 200Ah LifePO4 Powerwall Battery products are lithium ion batteries using lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. During the charging process, some of the lithium ions in the lithium iron phosphate are extracted, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction. During the discharge process, lithium ions come out from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy for the outside world.

The 48V 200Ah LifePO4 Powerwall Battery products have the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.

1. Improvement of safety performance
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances like lithium cobaltate, so it has good safety.

2. Improvement of lifespan
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the 48V 200Ah LifePO4 Powerwall Battery products have a cycle life of more than 2,000 times, and can reach 2,000 times with standard charging (5-hour rate).

3. Good high temperature performance
The 48V 200Ah LifePO4 Powerwall Battery products peak electric heat can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

4. Large capacity
Batteries often work under the condition of being fully charged, and the capacity will quickly drop below the rated capacity. This phenomenon is called memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used at any time without having to discharge it before charging.

6. Light weight
The volume of the 48V 200Ah LifePO4 Powerwall Battery products of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.

7. Environmental protection
The 48V 200Ah LifePO4 Powerwall Battery products are generally considered to be free of any heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, and are absolutely green battery certificates. Therefore, the reason why lithium-ion batteries are favored by the industry is mainly environmental protection, and it has become a key project supported and encouraged by the state.
