Silica material is synthesized from rice husks (from Tan Tru district, Long An province, Vietnam) according to the process of inert gas calcination and surface activation of the material with KOH. This is a simple, low-cost synthesis process because the entire amount of finished rice husk ash is researched and used as the cathode for Li-ion rechargeable batteries. Based on current research results, silica materials have the potential to completely replace commercial Graphite materials in terms of price and efficiency. Therefore, the application of trial production of rechargeable Li-ion batteries using silica anode materials synthesized from rice husks is very feasible to create Li-ion button batteries used in electronics components (watches, personal computers, etc…) or pocket-sized rechargeable Li-ion batteries (phones, compact electrical devices).
Expected output:
- 03 International scientific articles in prestigious journals under the SCI or SCIE categories, 03 domestic scientific articles.
- Report on the process of producing silica materials from rice husks used as electrodes for Li-ion rechargeable batteries.
Commercial Li-ion button battery products and Li-ion pocket batteries are tested according to industrial battery standards and are suitable for applications in mobile electronic devices.
