Semi Solid State 3.2V 280Ah Prismatic LiFePO4 Battery Cell

Semi Solid State 3.2V 280Ah Prismatic LiFePO4 Battery Cell

Solid-state batteries are a type of battery that uses solid electrolytes. Compared with traditional liquid batteries, they have the following advantages:

1. High safety: solid electrolytes are non-flammable and non-volatile, which can effectively reduce the risk of thermal runaway of batteries and reduce the risk of leakage.

2. High energy density: It can be adapted to high-capacity electrode materials, such as metal lithium negative electrodes, and has a compact internal structure and high space utilization, which can improve the overall energy density of the battery.

3. Good cycle performance: solid electrolytes can inhibit the volume change and side reactions of electrode materials during charging and discharging, and extend the battery cycle life.

4. Low self-discharge rate: solid electrolytes have good chemical stability, which can reduce the self-discharge reaction rate and reduce the power loss of batteries during long-term storage.

5. Wide operating temperature range: In high and low temperature environments, the performance of solid-state batteries is relatively stable, and they can maintain good charging and discharging efficiency at low temperatures, and are not prone to thermal stability problems at high temperatures.

6. High design flexibility: The shape of solid-state batteries can be customized according to needs, which is convenient for integration into equipment with different shapes and space requirements, providing more possibilities for product design.

Key Features

Compared with traditional lithium batteries, solid-state batteries have the following advantages:

• High safety: thermal stability is greatly improved, and it can withstand extreme situations such as puncture and cutting, which can eliminate the risk of thermal runaway. Reduce the risk of short circuit.

• High energy density: solid-state batteries are compatible with positive and negative electrode materials with high specific capacity, up to 400-500Wh/kg, and may even exceed 600Wh/kg in the future. The internal space utilization rate is high, and more dense electrolytes can be stuffed into it, shortening the distance between the positive and negative electrodes, reducing the volume, and increasing the energy density.

• Long cycle life: The solid electrolyte has strong stability, so that the battery life can reach 2000-5000 cycles, while traditional lithium batteries are about 1000-2000 times.

• Fast charging speed: The charging speed is 4-6 times faster than the liquid state, and the goal is to achieve "80% charging in 10 minutes". Its unique electrolyte structure makes the transmission efficiency of electrons and ions higher, which not only speeds up the charging speed, but also reduces the risk of overheating.

• Wide application temperature range: solid electrolytes are difficult to burn even at 200°C, can withstand high temperatures of 150°C, can work normally at low temperatures of -40°C, and can output stably in high and low temperature environments.

• High battery plasticity: All-solid-state batteries have increased flexibility after being made thinner and lighter, and can withstand hundreds to thousands of bends without sacrificing performance. They can be made into different shapes to meet the needs of different devices.
