Silicon is the most promising electrode material for next-generation lithium-ion batteries

Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the Nano silicon anode material silicon powder is undoubtedly a good investment opportunity.

Overview of nano silicon anode material silicon powder

Silicon is the most promising electrode material for next-generation lithium-ion batteries, with a specific capacity (3600 mAh/g) about 10 times higher than graphite (372 mAh/g). However, due to the significant expansion (over 300%) of the material under load (lithiation) and the instability of the solid electrolyte interface layer (SEI), its use is severely restricted. The poor mechanical stability and chemical passivation performance of silicon electrodes make the cycle performance of silicon electrodes far unable to meet the requirements of battery systems, and a lot of research and suggestions have been stimulated to circumvent these limitations.

During the lithium insertion process, the volume of silicon changes so much (about 400%) that the silicon cracks and falls off the collector, causing the prototype lithium-silicon battery to lose most of its capacity in less than 10 charge and discharge cycles. The key to the success of large-capacity lithium-ion batteries is to solve the capacity and stability problems of lithium-ion silicon.

Silicon anode materials have shown great potential in improving the efficiency and energy storage capacity of lithium-ion batteries. Until recently, their main disadvantage was surface passivation through oxidation, a process that increases impedance and reduces anode circularity. Our high-purity silicon anode materials can achieve high specific capacity without significantly affecting cycle life.

Nano silicon anode material silicon powder application

Silicon is the most promising anode material in the next generation of lithium-ion batteries. Nano silicon anode materials are used in cylindrical, flexible and aluminum shell batteries. Our silicon anode powder can be dispersed in the battery solvent while preventing agglomeration. They are designed to bond seamlessly with other battery materials and produce uniform and stable coatings. Therefore, they are suitable for a range of applications, including lithium-ion batteries, photovoltaics, semiconductors, and electronics.
