Abstract Prevention and mitigation of thermal runaway presents one the greatest challenges for safe operation lithium-ion batteries. Here, we demonstrate first time application high-speed synchrotron X-ray computed tomography radiography, in conjunction with imaging, to track evolution internal structural damage behaviour during initiation propagation This diagnostic approach is applied commercial batteries (LG 18650 NMC cells), yielding insights into key degradation modes including...

This paper presents a fast cost-effective technique for the measurement of battery impedance online in an application such as electric or hybrid vehicle. Impedance measurements on lithium-ion batteries between 1 Hz and 2 kHz give information about electrochemical reactions within cell, which relates to state charge (SOC), internal temperature, health (SOH). We concentrate development system that, first time, uses excitation current generated by motor controller. Using simple electronics...
Economically viable electric vehicle lithium-ion battery recycling is increasingly needed; however routes to profitability are still unclear. We present a comprehensive, holistic techno-economic model as framework directly compare locations and processes, providing key tool for cost optimization in an international economy. show that can be economically viable, with cost/profit ranging from (−21.43 - +21.91) $·kWh−1 but strongly depends on transport distances, wages, pack design method....
Predicting lithium-ion battery degradation is worth billions to the global automotive, aviation and energy storage industries, improve performance safety reduce warranty liabilities. However, very few published models of explicitly consider interactions between more than two mechanisms, none do so within a single electrode. In this paper, first attempt directly couple mechanisms in negative electrode reported. The results are used map different pathways through complicated path dependent...
The Lithium-ion battery (LIB) is an important technology for the present and future of energy storage, transport, consumer electronics. However, many LIB types display a tendency to ignite or release gases. Although statistically rare, fires pose hazards which are significantly different other fire in terms initiation route, rate spread, duration, toxicity, suppression. For first time, this paper collects analyses safety challenges faced by industries across sectors, compares them research...
Fast charging of batteries is currently limited, particularly at low temperatures, due to difficulties in understanding lithium plating. Accurate, online quantification plating increases safety, enables speeds closer the electrochemical limit and accelerates charge profile development. This work uses different cell cooling strategies expose how voltage plateaus arising from self-heating concentration gradients during fast can falsely indicate plating, contrary prevalent current assumptions....
Abstract Batteries that extend performance beyond the intrinsic limits of Li-ion batteries are among most important developments required to continue revolution promised by electrochemical devices. Of these next-generation batteries, lithium sulfur (Li–S) chemistry is commercially mature, with cells offering a substantial increase in gravimetric energy density, reduced costs and improved safety prospects. However, there remain outstanding issues advance commercial prospects technology...
The pursuit of low-carbon transport has significantly increased demand for lithium-ion batteries. However, the rapid increase in battery manufacturing, without adequate consideration carbon emissions associated with their production and material demands, poses threat shifting bulk upstream. In this article, a life cycle assessment (LCA) model is developed to account cradle-to-gate footprint batteries across 26 Chinese provinces, 20 North American locations 19 countries Europe Asia. Analysis...
Addressing the economic and environmental sustainability problems of today's road transport requires, inter alia, rapid introduction alternative, low-carbon fuels highly efficient, low-emission powertrains. It is unlikely that transition from oil-based conventional internal combustion engines will occur organically at necessary rate following an optimum path, hence policy intervention required. However, in order to design effective policies it essential potential role alternative...
A picture of the challenges faced by lithium-sulfur technology and activities pursued research community to solve them is synthesized based on 1992 scientific articles. It shown that, against its own advice adopting a balanced approach development, has instead focused work cathode. To help direct future work, key areas neglected are highlighted, including cell operation studies, modelling, anode, electrolyte production methods, as well development goals for real world target applications...
Lithium ion batteries are increasingly important in large scale applications where thermal management is critical for safety and lifetime. Yet, the effect of different boundary conditions on performance lifetime still not fully understood. In this work, a two-dimensional electro-thermal model developed to simulate cell internal states under complex conditions. Attention was paid model, only electrode stack but also non-core components (e.g. tab weld points) boundaries, experiments required...
This paper presents probabilistic estimates of the 2020 and 2030 cost cycle life lithium-ion battery (LiB) packs for off-grid stationary electricity storage made by leading experts from academia industry, insights on role public research development (R&D) funding other drivers in determining these. By 2020, expect developments to arise chiefly through engineering, manufacturing incremental chemistry changes, additional R&D have little impact cost. 2030, indicate that more fundamental changes...
