Electrochemical Flow Cell

While the Li-ion battery has been engineered over the last four decades to improve energy capacity, power density, and device safety, the useful lifetime of this essential energy storage technology has not progressed as much. This is largely due to experimental challenges of studying, characterizing, and understanding the SEI: the battery `component' most vital to ageing and failure. More importantly for the goal of improving Li-ion battery lifetime, researchers have lacked adequate diagnostic tools for studying how the SEI fails. Here we demonstrate a prototype electrochemical flow cell for the specific application of detecting crosstalk reactions in advanced Li-ion battery chemistries. We develop a generator-collector approach to understanding battery crosstalk and leverage finite-element simulations to guide design of this novel reactor. After calibrating the device using a known redox couple, the device is cycled under varying electrode configurations to detect capacity fade induced by the metal dissolution crosstalk mechanism. The path forward will involve adding new product detection capabilities and engineering a reactor environment that replicates a sealed Li-ion battery.

Storage Batteries

In addition to cost and lifetime, important factors in using lithium-ion (Li-ion) batteries as a backup power supply in telecommunication applications are safety and the flatness of discharge voltage to maintain compatibility with existing systems based on lead storage batteries. We have been researching Li-ion batteries using manganese spinel as cathode material from the viewpoints of flat discharge voltage and thermal stability in the event of overcharging or internal short-circuits. The safety of the Li-ion battery was improved by adding a phosphazene flame retardant to the electrolytic solution and cathode of the battery. Then, with the aim of extending battery lifetime, some of the manganese in the cathode was replaced by another metallic element, which showed favorable results.

Self Adaptive

A self-adaptive battery management system (BMS) based on CAN-bus for power Li-ion battery was designed in this paper. It is designed distributed and composed of sampling modules, a master module and some aid devices. The sampling module is used to sampling the voltage of the cells and the temperature in the pack. And it keeps the temperature in safe range by controlling the fans in the pack. The master module receives the information from the sampling modules, samples the current of the main road, estimates the state of charge (SOC), the state of health (SOH), controls the main road relays. The modules communicate with each other by CAN-bus. The fault and temperature management are performed adaptively. It is shown that this self-adaptive BMS extend the battery lifetime and guarantee safe operation. And the self-power consumption is very low.

The aim of this paper is to propose a methodology for managing the Li-ion battery lifetime of a whole fleet with the aim to improve the total cost of ownership of hybrid electric buses. This approach has been addressed from two points of view the bus-to-route and route-to-bus approaches. The bus-to-route optimization is focused on the energy management strategy generation of each bus of the fleet. A techno-economic, route energetic evaluation and battery aging analysis of the fleet have been performed. From the outcome of this analysis, the buses have been grouped, according the state of health of each bus. Based on the analysis and classification, the route-to-bus approach is applied. This technique lies on both, a re-evaluation of the energy management system and/or the re-organization of the buses according to the state of health of each bus. Increases of BT lifetimes up to 10.7% are obtained with the proposed approach.
