Wearable　flexible　devices　require　advanced　lithium-ion　batteries　(LIBs)　for　energy　supply,　thus　promotes　the　development　of　self-assembled,　binder-free,　film-type　anodes　with　the　advantage　of　no　additives,　strong　binding　force　and　low　contact　resistance.　Among　many　potential　candidates,　2H　phase　molybdenum　disulfide　(2H-MoS2)　has　been　attracting　much　attention　due　to　its　high　practical　capacity　and　graphene-like　structure.　However,　few　interests　are　paid　to　the　compactness　design　inside　the　in-situ　grown　MoS2　film　on　bendable　matrices,　leading　to　poor　structure　stability　and　low　volumetric　capacity.　Herein,　film　compactness　is　carefully　modulated　by　controlling　the　sputtering　parameters,　then　the　cross-section　microstructure　and　electrochemical　property　are　systematically　investigated.　Among　them,　the　dendritic-arranged,　middle　porosity　MoS2　(MP-MoS2)　offers　abundant　Li-ion　migration　channels,　delivering　an　enhanced　charge-discharge　capacity　of　1136　and　1157　mAh　center　dot　g(-1)　(similar　to　3.7　Ah.cm(-3))　after　300　cycles　at　1C.　MP-MoS2　(2　h)　with　the　same　structure　and　increased　mass　loading　can　also　stably　operate　for　400　cycles　without　decay.　Notably,　it　remains　stable　cycling　on　titanium　and　stainless-steel　matrices,　but　the　sharp　decay　often　occurs　within　tens　of　cycles　towards　common　copper　foil　due　to　Cu　diffusion　and　film　orientation　alteration,　implying　that　low-melting-point　flexible　matrices　are　not　suitable　for　in-situ　2H-MoS2　assembling　at　high　temperature.　This　work　provides　a　practical　analyzation　strategy　for　designing　film-type　2H-MoS2　anode　material　used　as　flexible　LIBs.
