OneD Battery Sciences of Palo Alto, CA, offers its silicon anode technology SINANODE as a "winning solution" to those challenges. Silicon anodes can store much more charge in LI batteries than graphite can—but
Lithium–silicon batteries are lithium-ion batteries that employ a silicon-based anode, and lithium ions as the charge carriers. [1] Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon. [2] The standard anode material graphite is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC 6.

Silicon anodes can store much more charge in LI batteries than graphite can—but silicon anodes can also undergo significant volumetric fluctuations when charging and discharging.
BTR is a new energy material R & D and manufacturer. The company''s core products are negative electrode materials and positive electrode materials for lithium-ion batteries, and its industry position is prominent.
With rapid development of battery technology, silicon gradually beomes a potential negative electrode material. As early as the 1970s, people discovered the electrochemical reaction between lithium (Li) and elemental silicon (Si). Through processing by grinding mill, eg: ball mill, silicon can be well used in negative elsctrode of battery.

It is understood that, as the first company in China to mass-produce silicon-based anodes, it has entered the supply chain of Panasonic, Tesla, and Samsung. BTR began to research and develop silicon-based anode materials in 2006. The technical route includes silicon-oxygen anode materials and silicon-carbon anode materials.
The performance of the synthesized composite as an active negative electrode material in Li ion battery has been studied. It has been shown through SEM as well as impedance analyses that the enhancement of charge transfer resistance, after 100 cycles, becomes limited due to the presence of CNT network in the Si-decorated CNT composite.
