button battery cr1620 will soon replace ternary lithium batteries

Earlier this year, the American Fisker Automobile Company released a new solid-state battery technology. It is reported that the energy density of this technology is 2.5 times that of conventional lithium-ion batteries, which can increase the driving range of electric vehicles to more than 500 miles (about 804 kilometers). What’s even more amazing is that its charging time only takes 1 minute, which is even faster than refueling a traditional fuel vehicle.

button battery cr1620 have two very significant advantages. On the one hand, traditional lithium batteries that use organic electrolytes can easily cause the electrolyte to heat up under abnormal conditions such as overcharging and internal short circuits, leading to safety hazards such as spontaneous combustion or even self-explosion. button battery cr1620 are based on the conditions that solid-state materials are non-flammable, non-corrosive, non-volatile, and non-leakable. Their safety factor has inherent advantages over lithium-ion batteries.

Secondly, button battery cr1620 are expected to completely solve the range anxiety of pure electric vehicles in terms of the most critical energy density. Lithium-ion batteries under the current system are close to their ultimate performance. Even the battery pack with Tesla NCA18650 cells has an energy density of 250 Wh/kg, and the energy density of the 21700 cells used in Model 3 reaches 300 Wh/kg. , supports a cruising range of 400 to 500 kilometers, but it still cannot solve the cruising range anxiety.

The electrolyte of button battery cr1620 does not require separators and electrolytes, and there are no problems such as leakage or corrosion. It can simplify the battery casing and cooling system modules, further reduce the weight of the battery module, and achieve energy saving effects. In addition, the new combination of positive and negative electrode materials can make the electrochemical window reach above 5V, fundamentally improving the energy density, which is expected to reach 500 Wh/kg.

From the current point of view, it is obvious that this goal cannot be achieved only by relying on the technological research and development of lithium batteries. In order to ensure the high energy density and safety of power batteries, the research and development progress of button battery cr1620 has brought light to the entire new energy vehicle industry. Therefore, button battery cr1620 are widely considered to be the correct technology research and development direction for the next generation of power batteries.

It usually takes about ten years for a newly developed material to move from the laboratory to the market application level. button battery cr1620 are still in the research and development stage, and you still need to wait patiently to achieve industrialization. Although it is widely believed that button battery cr1620 have the advantages of high safety and high energy density, they are only speculations on forward research and development. Only when their mass-produced products show absolute advantages can they truly replace ternary lithium batteries.

In fact, whether it is ternary or iron-lithium, for now, the most critical thing is to adapt to the needs of the entire market. The main thing is to make users feel at ease and we can rest assured. At this stage, lithium iron phosphate batteries can meet customer requirements and do not burn, catch fire or explode. What else can you refuse?
