Solid State Battery Advantages

Solid State Battery Advantages

Advantage 1:

Light - high energy density. After the use of all-solid electrolytes, the applicable material system of lithium-ion batteries will also change, of which the core point is that you do not need to use lithium embedded graphite anode, but directly use lithium metal to do the negative electrode, which can significantly reduce the amount of negative electrode materials, so that the energy density of the entire battery has been significantly improved.

Advantage 2:

Thin -- small in size. In traditional lithium-ion batteries, membranes and electrolytes are used, which together account for nearly 40 percent of the volume and 25 percent of the mass in the battery. And if they are replaced with solid electrolytes (mainly organic and inorganic ceramic materials two systems), the distance between the positive and negative electrodes (traditionally filled by diaphragm electrolyte, now filled by solid electrolyte) can be shortened to even only a few to a dozen microns, so the thickness of the battery can be greatly reduced - so all-solid-state battery technology is battery miniaturization, The only way to film.

Advantage 3:

Flexible outlook. Even brittle ceramic materials are often flexible after a thickness of less than millimeters, and the material becomes flexible. Accordingly, the degree of flexibility of the all-solid-state battery will also be significantly improved after thin and thin, by using the appropriate packaging material (not a rigid shell), the made of the battery can withstand hundreds to thousands of bending to ensure that the performance is basically not attenuated.

Advantage 4:

It's safer. Traditional lithium batteries may have the following dangers: (1) lithium dendrites may appear in the operation of large current, which may puncture the diaphragm and lead to short circuit damage (2) the electrolyte is an organic liquid, and the tendency of side reactions, oxidative decomposition, gas generation, and combustion will be intensified at high temperatures. Using all-solid-state battery technology, the above two problems can be directly solved.
