Processes associated with lithium batteries may produce adverse respiratory, pulmonary and neurological health impacts. Pollution from graphite mining in China has resulted in reports of " graphite rain ", which is significantly impacting local air and water quality.
When electrons move from anodes to cathodes—for instance, to move a vehicle or power a phone to make a call—the chemical energy stored is transformed into electrical energy as ions move out of the anode and into the cathode. When a battery is charging, electrons and ions flow in the opposite direction. As it is generally easier to remove

Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
Electrolyte decomposition limits the lifetime of commercial lithium-ion batteries (LIBs) and slows the adoption of next-generation energy storage technologies. A fundamental understanding of electrolyte degradation is critical to rationally design stable and energy-dense LIBs.
Both battery cycling and time cause battery aging, and battery aging is accelerated by the DOD and frequency of cycles, thermal conditions, and SOC/voltage
Both battery cycling and time cause battery aging, and battery aging is accelerated by the DOD and frequency of cycles, thermal conditions, and SOC/voltage conditions experienced by the battery. Three primary underlying chemical processes occur during lithium battery aging: loss of cyclable lithium; electrode material loss to dissolution; and

Consequently, the safety of a battery system can be improved by firstly avoiding the conditions that lead to heat and gas generation, and secondly, if it does occur, by managing the heat and gas generated to alleviate battery failure. Safety vents and current interruption devices that open in response to pressure increase inside the cell to allow the gases escape
Interface problems can be affected not only by physical properties but also by chemical properties, as the cathode in a battery is usually more oxidized and the lithium anode is more reduced. Therefore, the electrolyte should be highly resistant to oxidation on the side in contact with the cathode and to reduction on the side near the anode, and have high chemical stability

Introduction Understanding battery degradation is critical for cost-effective decarbonisation of both energy grids 1 and transport. 2 However, battery degradation is often presented as complicated and difficult to understand. This perspective aims to distil the knowledge gained by the scientific community to date into a succinct form, highlighting the
The profound environmental impact of batteries can be observed in different applications such as the adoption of batteries in electric vehicles, marine and aviation industries and heating and cooling applications.
However, the contribution of batteries to life cycle emissions hinge on a number of factors that are largely absent from previous analyses, notably the interaction of battery chemistry alternatives and the number of electric vehicle kilometers of travel (e-VKT) delivered by a battery.
Similarly, for batteries to work, electricity must be converted into a chemical potential form before it can be readily stored. Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.
This probabilistic approach to considering life cycle battery performance as a function of chemistry and based on a meta-analysis of battery performance data, shows that the exclusion of production-related emissions for PEVs and realistic operating performance may ignore tradeoffs in production and operation emissions of PEVs.
The presence of batteries in marine and aviation industries has been highlighted. The risks imposed by batteries on human health and the surrounding environment have been discussed. This work showcases the environmental aspects of batteries, focusing on their positive and negative impacts.
Scientists study processes in rechargeable batteries because they do not completely reverse as the battery is charged and discharged. Over time, the lack of a complete reversal can change the chemistry and structure of battery materials, which can reduce battery performance and safety.
