All‐Solid‐State Lithium‐Ion Microbatteries: A Review of Various Three‐Dimensional Concepts

“…[ 15 ] A second method for the formation of LIPON is pulsed laser deposition, in which also both the nitrogen partial pressure and the laser power infl uence the ionic conductivity. [ 120 ] A third method that was reported to yield ionically conductive LIPON fi lms is ion-beam assisted deposition (IBAD). [ 121 , 122 ] LIPON fi lms have very high ionic conductivities compared to other inorganic solid-state electrolytes: up to 3 ⋅ 10 − 6 S ⋅ cm − 1 of VO 2 (sol-gel coating, [ 85 ] RF sputter deposition, [ 86 ] pulsed laser deposition [ 82 ] and chemical vapor deposition [ 87 ] ).…”

“…At these decreased synthesis temperatures, the low-temperature phase b-Li 10 P 4 N 10 became accessible. After optimization,i tc ould be synthesized according to Equations (1), (2), (3), or (4). For all of these routes,w eu sed a Li 3 Nf lux or self-flux,i no pen Ta crucibles sealed in silica ampoules under argon or nitrogen atmosphere, with different excesses of Li 3 No rL i 7 PN 4 as appropriate.…”

“…[1][2][3][4][5][6] Nitridophosphates are of particular interest due to their structural variability.T he ability to form different linking patterns of corner-and/oredge-sharing PN 4 tetrahedra as primary building units leads to av ariety of complex structures and allows materials to be optimized for many purposes. [7][8][9][10][11] Synthetic approaches to nitridophosphates are somewhat challenging due to the limited thermal stability of the starting materials (e.g.,P 3 N 5 decomposes above 850 8C).…”

“…[22] At ricyclic ring structure of one vierer-ring with two annelated dreier-rings is the characteristic structural motif [P 6 N 16 ] 18À in Li 18 P 6 N 16 , which has hitherto only been accessible under conditions of high temperature and high pressure (1000 8C, 5.5 GPa). [24] aLi 10 P 4 N 10 (720 8C, ambient pressure) consists of adamantane-like [P 4 N 10 ] 10À ions, isoelectronic with [P 4 O 10 ].

“…[29] The conductivities of these lithium nitridophosphates are comparable to those of other lithium nitride compounds of p-block elements.L iPON (1.6 10 À6 W À1 cm À1 at 25 8C, 0.58 eV), for example, has already found applicationa sasolid electrolyte in thinfilm batteries. [4] Differences in the conductivities of these compounds depend on their crystal structures, the coordinationo f the lithiuma toms, and the number of available charge carriers. [24] Trends in knownL i + ion conductors show that a bcc anion framework allows the lowest activation barrier and highest ionic conductivity,b ecause it allows direct Li hops between tetrahedral sites.…”
