abstract = {Na metal anode attracts increasing attention as a promising
candidate for Na metal batteries (NMBs) due to the high
specific capacity and low poten-tial. However, similar to
issues faced with the use of Li metal anode, crucial
problems for metallic Na anode remain, including serious
moss-like and den-dritic Na growth, unstable solid
electrolyte interphase formation, and large infinite volume
changes. Here, the rational design of carbon paper (CP) with
N-doped carbon nanotubes (NCNTs) as a 3D host to obtain
Na@CP-NCNTs composites electrodes for NMBs is demonstrated.
In this design, 3D carbon paper plays a role as a skeleton
for Na metal anode while vertical N-doped carbon nanotubes
can effectively decrease the contact angle between CP and
liquid metal Na, which is termed as being “Na-philic.”
In addition, the cross-conductive network characteristic of
CP and NCNTs can decrease the effective local current
density, resulting in uniform Na nucleation. Therefore, the
as-prepared Na@CP-NCNT exhibits stable electrochemical
plating/strip-ping performance in symmetrical cells even
when using a high capacity of 3 mAh cm−2 at high current
density. Furthermore, the 3D skeleton structure is observed
to be intact following electrochemical cycling with minimum
volume change and is dendrite-free in nature.},
