Abstract:
Red phosphorus (RP) has aroused growing concern as a promising anode material for Li-ion and Na-ion batteries due to its high theoretical capacity of 2596 mAhg-1 and appropriately low redox potential of ~0.4 V. However, the poor electronic conductivity of RP and its large volume expansion during lithiation lead to rapid capacity fading after first several cycles [1]. It is known, that threatment of electrodes by irradiation can possitively affect their performances.
In this work, the commercial RP powder with an average particle size 20-30 μm was ball milled until the nano- and mesosize 140 nm - 5 μm. In order to improve the capacity retention, the milled RP particles were coated by carbon black. A water-soluble sodium alginate was used as a binder [2]. The anodes were fabricated using the ratio RP:CB:SA (6:3:1). The electrodes were irradiated by 0,5 MeV proton pulsed beam. To analyze the structure and composition of the investigated XRD, Raman spectroscopy and SEM were carried out before and after irradiation.
The electrochemical tests of the nontreated and treated electrodes were performed in the coin-type 2032 cell, soaked in a few drops of 1M LiPF6 in ethyl, diethyl, ethyl methyl carbonates (EC:DEC:EMC 1/1 by vol.) + 5% fluoroethylene carbonate (FEC) as electrolyte with the Celgard 2400 separator and Li metal as the opposite and reference electrode. The experimental results and characterization details will be discussed at the conference.
