1. A [includes the anode bow material which shows with 2] S AX,
Minute description A is the alkali metal,
Minute description X I, Br, Cl, F and BF [4], BH [4], SO [4], BO [3], PO [4], O, Se, N, P, the As, Sb and PF [6], AsF [6], ClO [4], NO [3], CO [3], CF [3] SO [3], CF [3] COO and N (SO [2] F) [2] and N (CF [3] SO [from 2]) [2] the former solid second which is selectedBattery suspicion anode.
[claim2]
2. There is in a first clause, and the minute description alkali metal is Li or Na,
As for minute description AX the case where A is Li, LiI, LiBr, LiCl, LiF and LiBF [4], LiBH [4], Li [2] SO [4], Li [3] BO [3], Li [3] PO [4], Li [2] O and Li [2] Se and Li [3] N and Li [3] P and Li [3] As and Li [3] Sb and LiPF [6], LiAsF [6], LiClO [4], LiNO [3], Li [2] CO [3], LiCF[3] SO [3], LiCF [3] COO and LiN (SO [2] F) [2] and LiN (CF [3] SO [from 2]) [2] is selected, and the case where A is Na, NaI, NaBr, NaCl, NaF and NaBF [4], NaBH [4], Na [2] SO [4], Na [3] BO [3], Na [3] PO [4], Na [2] O and Na [2] Se and Na [3] N and Na [3] P and Na[3] As and Na [3] Sb and NaPF [6], NaAsF [6], NaClO [4], NaNO [3], Na [2] CO [3], NaCF [3] SO [3], NaCF [3] COO and NaN (SO [2] F) [2] and NaN (CF [3] SO [from 2]) [2] the former solid secondary battery suspicion anode which is selected.
[claim3]
3. There to be in a first clause, minute description A [2] S AX A [2] S and AX 99:1 -20: 80 (molar ratio) at ratio as for under including former solid secondary battery suspicion anode.
[claim4]
4. Is in first clause, in addition, re-defiant becomes accomplished with the carbon material, about minute description anode bow material 100 weight department, at ratio of 0.1-50 weight department as for under including the former solid secondary battery suspicion anode.
[claim5]
5. Before there is in a first clause, and the minute description former solid secondary battery is the enemy layer body of the anode, solid electrolytic layer and the cathode, and the minute description solid electrolytic layer A [2] S M [x] S [y] (as for A first protest justice and is identical, and M is selected from P, Si, Ge, B, the Aluminum and the Ga, and x and as for y according to type of M, the low of providing is the essence) as electrolyte to include a stoichiometry expense, and the minute description anode does not include a minute description electrolyte, the solid secondary battery suspicion anode.
[claim6]
6. With manufacturing method of the anode which is recorded to request port 1, before A [2] S and AX a mechanical milling control accomplishes with A [getting 2] S AX, manufacturing method of the solid secondary battery suspicion anode.
[claim7]
7. There is in a 6th clause, and the minute description mechanical milling control the meteor style uses the wheat see and from, 50-700 former/minutes, 0.1-30 hour, before 1-100kWh/1kg (A [2] S and AX total weighting) becoming accomplished from under condition, manufacturing method of the solid secondary battery suspicion anode.
[claim8]
8. There is in a 6th clause, and the minute description anode in addition includes re-defiant becomes accomplished with the carbon material, and the minute description anode A [with 2] S AX re-defiant accomplishes a mechanical milling control with manufacturing method of the former solid secondary battery suspicion anode which reaches several profits.
[claim9]
9. The anode and A which are recorded to first clause [2] S M [x] S [y] (A minute description and is identical, and M is selected from P, Si, Ge, B, the Aluminum and the Ga, and x and as for y, according to type of M, stoichiometry expense as for under providing is the essence) with the solid electrolytic layer which shows the low of including the former solid secondary battery.
