More importantly, compared with the cells using Celgard separator, the cells with MSD-PI separator exhibit superior electrochemical performance, especially long-term cycle performance under high temperature environment, owing to the high thermal conductivity of surface Si3N4 particles. Hence, lithium-ion batteries with MSD-PI separator are capable of improving thermal safety and capacity retention, which demonstrates that magnetron sputtering deposition technique could be regarded as a promising strategy to develop advanced organic/inorganic composite separators for high-temperature lithium-ion batteries.

SiNx is demonstrated to be a compelling anode for LIBs, and with further development and optimization this might become the leading contender for the high capacity anode to possibly succeed current graphitic electrodes.
