Pioneer study of SiP2 as negative electrode for Li- and Na-ion batteries†
Abstract
For the first time it is demonstrated that a dense SiP2 pyrite-type obtained by a very simple ball milling method delivers outstanding capacity in both lithium and sodium batteries with up to 1000 mA h g−1 and 572 mA h g−1 sustained after 30 and 15 cycles respectively.
