Fabrication of Three-Dimensional Battery Using Ceramic Electrolyte with Honeycomb Structure by Sol–Gel Process

With the increasing importance of wireless microelectronic devices the need for on-board power supplies is evidently also increasing. Possible candidates for microenergy storage devices are planar all-solid-state Li-ion microbatteries, which are currently under development by several start-up companies. However, to increase the energy density of these microbatteries further and to ensure a high power delivery, three-dimensional (3D) designs are essential. Therefore, several concepts have been proposed for the design of 3D microbatteries and these are reviewed. In addition, an overview is given of the various electrode and electrolyte materials that are suitable for 3D all-solidstate microbatteries. Furthermore, methods are presented to produce fi lms of these materials on a nano-and microscale.www.MaterialsViews.com REVIEW www.advenergymat.de

“…We have succeeded on preparation of ceramics electrolyte with 3DOM structure and proven that the 3DOM electrode is one of the promising structures for all-solid-state battery. 8), 9) Recently, a new family of Li conductive ceramics with a garnet-like structure has been reported by Weppner et al 10), 11) Among them, Li 7 La 3 Zr 2 O 12 (LLZ) 12) is stable against Li metal, implying that the Li metal anode can be applied to the LLZ. Li metal is the best anode material because of high capacity and low redox voltage of ¹3.045 vs. SHE which leads to high operation voltage and high power of battery.…”

2-layered all-solid-state battery, which is made up of 3DOM (3dimensionally ordered macroporous) porous layer and dense layer, is one of the promising structures for all-solid-state Li battery with Li metal anode. In this paper, an influence of precursor powder size of solid electrolyte on formation of 2-layered electrolyte which is a framework of all-solid-state battery was studied using Li 0.35 La 0.55 TiO 3 (LLT) electrolyte. The particle size strongly affected on morphology of prepared 2-layered structure. In the case of mixture of milled powder with below 1 µm diameter and non-milled powder with sub µm in weight ratio = 3:1, completely sintered 2-layered LLT could be obtained. This would be due to high bulk density of the mixture. Li ion conductivities of obtained 2-layered LLT at bulk and grain boundary were 8.0 © 10 ¹4 and 2.6 © 10 ¹5 S cm ¹1, respectively, which were well consistent with reported values. These findings imply the 2-layered structure can be prepared by many kinds of ceramics if size of precursor powder would be controlled properly.

In another study, 3D batteries were fabricated using a honeycomb, LLT electrolyte filled with oxide cathode particles and sol gel precursors (Kotobuki et al 2010c). Good electrolyte-electrode contact was formed via this method, and a battery utilizing an LiMnO 4 cathode displayed low interfacial impedance.…”

From aqueous liquid electrolytes for lithiumair cells to ionic liquid electrolytes that permit continuous, high-rate cycling of secondary batteries comprising metallic lithium anodes, we show that many of the key impediments to progress in developing next-generation batteries with high specific energies can be overcome with cleaver designs of the electrolyte. When these designs are coupled with as cleverly engineered electrode configurations that control chemical interactions between the electrolyte and electrode or by simple additives-based schemes for manipulating physical contact between the electrolyte and electrode, we further show that rechargeable battery configurations can be facilely designed to achieve desirable safety, energy density and cycling performance.
