Electrochemical Cell Preparation on MEMS Chip Surface Inside Scanning Electron Microscope

This paper reports the preparation process of an electrochemical cell consisting of metallic lithium, lithium titanate, and ionic liquid on a MEMS chip surface. Firstly, the MEMS chip is described and the connectivity test of the used pads is performed using voltage contrast imaging. Then the process of electrode preparation using the FIB-SEM technique is described in detail. Special attention is paid to lithium, its degradation during transport into the SEM chamber, and the behavior during ion beam cutting. Finally, a complete battery system was built. It was possible to measure charging/discharging of the model battery system, nevertheless, the functionality was affected by the redeposition of conductive materials on the MEMS surface and charging by an electron beam.

Luggage Tracking System Using IoT

The luggage tracking system is designed to track the luggage and bags which gets lost or theft from public and other areas. When people travel, there is always the chance of their luggage and bags being stolen, which is where the proposed system comes in. The luggage tracking system is based on an alert system that uses an Arduino Nano board and a GPS module. The alarm is also activated if the bag is stolen and moves outside of a certain range. Furthermore, a map is constructed via which we can monitor the location of the bag as it moves by dropping markers, which in turn informs us the location of the bag as it moves away from the owner. In this, the IOT components are being used like Arduino Board and a GPS Module in order to track the bag and to keep track of things, a frontend or mobile app is constructed. Keywords: IOT components, Arduino board, GPS, GSM model, Battery booster, Buzzer, Bluetooth model.

A heat-melt adhesive-assisted transferable electrode films

This report is the first on heat-assisted transferable battery components, enabling manufacturing batteries on non-planer surfaces such as a curved surface and an edge. The transferrable battery components were composed of two layers: a cathode or an anode and a conductive heal-melt adhesive layer on a silicone-based flexible supporting paper. These mechanically-durable, flexible components enabled conformable adhesion even on curved surfaces and substrate edges. As a model battery, the manganese dioxide-zinc system was constructed on a curved surface using transfer techniques and showed a practical capacity of 1.8 mAh cm−2 per unit electrode area. These transferable electrodes allow arbitrary design of batteries according to the power consumption of IoT devices to be fabricated on unreported geometries where has been considered as a dead space.

Modelling Lithium-Ion Battery Ageing in Electric Vehicle Applications—Calendar and Cycling Ageing Combination Effects

Battery ageing is an important issue in e-mobility applications. The performance degradation of lithium-ion batteries has a strong influence on electric vehicles’ range and cost. Modelling capacity fade of lithium-ion batteries is not simple: many ageing mechanisms can exist and interact. Because calendar and cycling ageings are not additive, a major challenge is to model battery ageing in applications where the combination of cycling and rest periods are variable as, for example, in the electric vehicle application. In this work, an original approach to capacity fade modelling based on the formulation of reaction rate of a two-step reaction is proposed. A simple but effective model is obtained: based on only two differential equations and seven parameters, it can reproduce the capacity evolution of lithium-ion cells subjected to cycling profiles similar to those found in electric vehicle applications.

Design and Construction of Model Battery Charging Control for Stand-alone self-Excited Induction Generator

In this paper, design and construction of model battery charging control for stand-alone wind driven self-excited induction generator SEIG) is present. Apart from an energy transfer function from wind turbine (WT) with stand-alone SEIG, the proposed model battery charging control can also be an active power in linear loads with stand-alone for a three-phase four wire system. Initially, mathematical modeling of the wind turbine with stand-alone SEIG is given. The simulation based on mathematical equations obtained from the model provides electrical characteristics of the wind turbine source that which will be use as the battery charging control input of the inverter. Secondly, the main system has been virtually create in order to actualize the conversion from DC to AC and the main power circuit employs insulated gate bipolar transistors (IGBTs) formed in a three-phase full bridge. Thirdly, the control circuit is discuss and has been design and the control method used is voltage control with microcontroller for stand-alone linear loads that is simple. Finally, the obtained results are discusses in order to verify the correct operation as the system is designed.

Constant Potential, Electrochemically Active Boundary Conditions for Electrochemical Simulation

This manuscript presents a theoretical model for simulating molecular dynamics at electrode-electrolyte interfaces. The novelty of the model is that it combines a method for simulating constant potential electrodes and a method for simulating stochastic interfacial charge transfer. We combine these methods to simulate model electrochemical systems under driven conditions, where charge is flowing across the electrode-electrolyte interface. The manuscript describes the theoretical formalism and applies it to a model battery system. We highlight the ability of the model to support the formation of electrical double-layers and to provide microscopic physical insight the results of potential jump experiments.
