Silicon Anode Battery Offers More Energy Density than Graphite and More Stability than Lithium
Silicon anode battery technology is gaining popularity in the battery market. Factors supporting the growth of this market include highest known capacity and relatively low working potential of silicon along with extended battery life, faster charging and long lasting battery. Its high power density due to its high working voltage, excellent chemical makeup and stable non-dissipating environment are some of the driving forces that fuel the silicon battery industry. This is the reason why many industries ranging from automotive industry to medical devices prefer the usage of these batteries over the other existing batteries. One of the most popular types of silicon anode battery is lithium–silicon battery. Silicon-based anodes offer more energy density than graphite and more stability than lithium. Silicon (Si) is a promising material due to its attractive theoretical specific capacity (>3500 mAh for Li-ion system) and low discharge potential ( ∼ 370 mV vs. Li/Li+). Silicon is k
