Information

The development of electric vehicles is in full swing. As one of the most important parts, the power battery plays a decisive role in the battery life and safety of electric vehicles. Recently, we often hear some terms such as solid-state battery, honeycomb energy jelly battery, NIO car nickel 55 battery, Zhiji car silicon-doped lithium supplement, and CTP/CTC technology. In fact, the fundamental purpose of so many technical directions is to improve the energy density and safety of batteries.

The battery cell consists of three parts, the positive electrode, the negative electrode, and the electrolyte between the positive and negative electrodes. To improve the energy density, we start from these three aspects. Let's look at them one by one.

Positive electrode - nickel 55 single crystal material, the single crystal structure can achieve higher voltage, not only that, but also improve the cycle stability of the ternary material and greatly improve the safety of the battery.
Negative electrode - "silicon-doped lithium supplementation" technology: Through this complex lithium supplementation process, the density of negative electrode materials can be increased. It is not known what kind of technology Zhiji car is, but it is basically a foregone conclusion that Zhiji car will use this high-end lithium battery.

Electrolytes - Solid State Batteries & Jelly Batteries

The jelly battery is a lithium battery using a new type of jelly-like electrolyte. This gel-type electrolyte can better fit the surface of the electrode material, and has the characteristics of self-healing and flame retardant. At the same time prevent thermal diffusion. The jelly battery can be said to be a transition from the development of liquid batteries to solid-state batteries.
