In the next five to ten years, silicon anode batteries' application will become better and better

wallpapers Tech 2020-09-16
Today, lithium battery technology is widely used.

The current lithium battery technology needs to be improved in terms of energy density and single battery cost. Any considerable change in parameters is revolutionary and will revolutionize transportation, power grids and clean energy.
In fact, due to different application scenarios, battery performance requirements are also other. For example, the power battery is used as a mobile power source. Under the premise of safety, the volume (and mass) energy density is as high as possible to achieve a longer-lasting battery life; most energy storage devices do not need to be moved, so energy storage Lithium batteries have no direct requirements for energy density, but other aspects such as power density and cost have different requirements in different energy storage scenarios.

The most important indicator of a battery is energy density, which is the energy that can be stored per unit weight or unit volume. The measurement of battery performance also includes indicators such as unit cost, service life, charging speed, and safety. There is still much room for improvement.

For example, as the charging speed increases, the charging infrastructure needed by the entire society can be eliminated because the construction of charging facilities requires a lot of investment costs. The key to improving these properties is to replace the anode and cathode materials, mainly the anode material.

At present, lithium-ion batteries' mainstream cathode material is a metal oxide, while the mainstream anode material is graphite. This type of battery's weight energy density is generally 250 Wh/kg ~ 300 Wh/kg, but if graphite is replaced with silicon, It can reach 400 watt-hours/kg. For lithium-sulfur, 500 watt-hours per kilogram or even 600-800 watt-hours per kilogram will be possible.

Therefore, in the next five to ten years, silicon anodes will be continuously used, and the more used, the better.
