Abstract

Solid-state electrolytes are a promising replacement for current organic liquid electrolytes, enabling higher energy densities and improved safety of lithium-ion (Li-ion) batteries. However, a number of setbacks prevent their integration into commercial devices. The main limiting factor is due to nanoscale phenomena occurring at the electrode/electrolyte interfaces, ultimately leading to degradation of battery operation. These key problems are highly challenging to observe and characterize as these batteries contain multiple buried interfaces. One approach for direct observation of interfacial phenomena in thin film batteries is through the fabrication of electrochemically active nanobatteries by a focused ion beam (FIB). As such, a reliable technique to fabricate nanobatteries was developed and demonstrated in recent work. Herein, a detailed protocol with a step-by-step process is presented to enable the reproduction of this nanobattery fabrication process. In particular, this technique was applied to a thin film battery consisting of LiCoO₂/LiPON/a-Si, and has further been previously demonstrated by in situ cycling within a transmission electron microscope.

In Situ STEM-EELS Observation of Nanoscale Interfacial Phenomena in All-Solid-State Batteries

Journal Article Wang, Ziying ; Santhanagopalan, Dhamodaran ; Zhang, Wei ; ... - Nano Letters

Behaviors of functional interfaces are crucial factors in the performance and safety of energy storage and conversion devices. Indeed, solid electrode–solid electrolyte interfacial impedance is now considered the main limiting factor in all-solid-state batteries rather than low ionic conductivity of the solid electrolyte. In this paper, we present a new approach to conducting in situ scanning transmission electron microscopy (STEM) coupled with electron energy loss spectroscopy (EELS) in order to uncover the unique interfacial phenomena related to lithium ion transport and its corresponding charge transfer. Our approach allowed quantitative spectroscopic characterization of a galvanostatically biased electrochemical system under in situmore »« less

Analysis of an all-solid state nanobattery using molecular dynamics simulations under an external electric field

Journal Article Ponce, Victor ; Galvez-Aranda, Diego E. ; Seminario, Jorge M. - Physical Chemistry Chemical Physics. PCCP

Present Li-ion battery (LIB) technology requires strong improvements in performance, energy capacity, charging-time, and cost to expand their application to e-mobility and grid storage. Li-metal is one of the most promising materials to replace commercial anodes such as graphite because of its 10 times higher specific capacity. However, Li-metal has high reactivity with commercial liquid electrolytes; thus, new solid materials are proposed to replace liquid electrolytes when Li-metal anodes are used. We present a theoretical analysis of the charging process in a full nanobattery, containing a LiCoO₂ cathode, a Li₇P2S₈I solid-state electrolyte (SSE), a Li-metal anode as well as Al and Cu collectors for the cathode and anode, respectively. In addition, we added a Li₃P/Li₂S film as a solid electrolyte interphase (SEI) layer between the Li-anode and SSE. Thus, we focus this study on the SEI and SSE. We simulated the charging of the nanobattery with an external voltage by applying an electric field. We estimated temperature profiles within the nanobattery and analyzed Li-ion transport through the SSE and SEI. Here, we observed a slight temperature rise at the SEI due to reactions formingmore »« less

Cryogenic Focused Ion Beam Characterization of Lithium Metal Anodes

Journal Article Lee, Jungwoo Z. ; Wynn, Thomas A. ; Schroeder, Marshall A. ; ... - ACS Energy Letters

Lithium metal is viewed as the ultimate battery anode because of its high theoretical capacity and low electrode potential, but its implementation has been limited by low Coulombic efficiency and dendrite formation above a critical current density. Determining the fundamental properties dictating lithium metal plating–stripping behavior is challenging because characterization techniques are limited by the sensitivity of lithium metal to damage by external probes, which regularly results in altered morphology and chemistry. Motivated by recent application of cryogenic transmission electron microscopy (cryo-TEM) to characterize lithium metal at the atomic scale, we explore the cryogenic focused ion beam (cryo-FIB) method asmore »« less

Stable Supercapacity of Binder-Free TiO₂(B) Epitaxial Electrodes for All-Solid-State Nanobatteries

Journal Article Kim, Dongha ; Jeon, Jingyeong ; Park, Joon Deok ; ... - Nano Letters

Owing to its pseudocapacitive, unidimensional, rapid ion channels, TiO₂(B) is a promising material for application to battery electrodes. In this study, we align these channels by epitaxially growing TiO₂(B) films with the assistance of an isostructural VO₂(B) template layer. In a liquid electrolyte, binder-free TiO₂(B) epitaxial electrodes exhibit a supercapacity near the theoretical value of 335 mA h g^–1 and an excellent charge–discharge reproducibility for ≥200 cycles, which outperform those of other TiO₂(B) nanostructures. For the all-solid-state configuration employing the LiPON solid electrolyte, excellent stability persists. Our findings suggest excellent potential for miniaturizing all-solid-state nanobatteries in self-powered integrated circuits.

High voltage stability of LiCoO2 particles with a nano-scale Lipon coating

Journal Article Kim, Yoongu ; Veith, Gabriel M ; Nanda, Jagjit ; ... - Electrochimica Acta

For high-voltage cycling of rechargeable Li batteries, a nano-scale amorphous Li-ion conductor, lithium phosphorus oxynitride (Lipon), has been coated on surfaces of LiCoO{sub 2} particles by combining a RF-magnetron sputtering technique and mechanical agitation of LiCoO{sub 2} powders. LiCoO{sub 2} particles coated with 0.36 wt% ({approx}1 nm thick) of the amorphous Lipon, retain 90% of their original capacity compared to non-coated cathode materials that retain only 65% of their original capacity after more than 40 cycles in the 3.0-4.4 V range with a standard carbonate electrolyte. The reason for the better high-voltage cycling behavior is attributed to reduction in themore »« less
