The common notation for battery packs in parallel or series is XsYp – as in, the battery consists of X cell “stages” in series, where each stage consists of Y cells in parallel.
Conferences > 2014 IEEE International Elect... Large-format Lithium-ion battery packs consist of the series and parallel connection of elemental cells, usually assembled into modules. The required voltage and capacity of the battery pack can be reached by various configurations of the elemental cells or modules.
Battery pack configuration develops toward the series connection due to the high energy density of the individual battery cell and lower management difficulty. Therefore, the accurate and robust estimations of state-of-charge (SOC) and capacity for series-connected battery packs are greatly essential.
This paper proposes a low-complexity SoC estimation method for series-connected battery pack and has three original contributions as follows. Firstly, taking practical applications into account, the capacity and SoC calculation of battery pack is simplified based on the probability theory analysis.
At some point, the 3.6 V of a single lithium ion battery just won't do, and you'll absolutely want to stack LiIon cells in series. When you need high power, you've either got to increase voltage or current, and currents above say 10 A require significantly beefed up components.
The current through each module is identical, which ensures uniform electric capacity throughput across the series configuration. The battery pack capacity is governed by the module with the minimum available discharge capacity () and the module with minimal available charge capacity () . They are respectively defined as: (16) (17)
It is thus worth investigating if different configurations lead to different performance of the battery pack in presence of a mismatch in the cell characteristics. A simulation tool is developed in this work and applied to a battery pack consisting of standard 12 V modules connected with various serial/parallel topologies.

This review concetrated on the emerging technology of DESs leaching for positive electrode materials in spent lithium-ion battery.
The lithium-ion battery was the technology of choice to develop 85.6% of the energy storage systems already in 2015 . Lithium, cobalt, and nickel play a central role in giving batteries greater performance, longevity, and higher energy density.
Research on more efficient pre-treatment technologies for spent lithium-ion batteries is also necessary. Current recycling processes for spent lithium-ion batteries mostly involve mechanical crushing into black powder, which makes the leaching of cathode materials in DESs difficult.
In industrial waste of discarded spent lithium-ion batteries, there are generally other metal impurities present, such as copper and aluminum foils used as current collectors. The aforementioned studies did not consider the leaching of impurities like copper in the current collector.
DESs for Spent lithium Battery recycling have been reported for the leaching of cathode materials as organic extractants and for the removal of Polyvinylidene fluoride (PVDF) binders.

Lithium-ion batteries have the potential to catch fire or explode if not handled, stored, or charged correctly. This can result in property damage, injuries, and even fatalities.
Lithium-ion battery fire hazards are associated with the high energy densities coupled with the flammable organic electrolyte. This creates new challenges for use, storage, and handling.
However, there are risks associated with lithium-ion batteries, and firefighters must be aware of the challenges they present and the measures needed to mitigate these dangers when tackling incidents involving these devices. Overcharging and overheating: Overcharging a lithium-ion battery beyond its designed capacity can lead to overheating.
Lithium battery fires and accidents are on the rise and present risks that can be mitigated if the technology is well understood. This paper provides information to help prevent fire, injury and loss of intellectual and other property. Lithium batteries have higher energy densities than legacy batteries (up to 100 times higher).
Lithium-ion batteries contain volatile electrolytes, and when exposed to high temperatures or physical damage, they can release flammable gases. Batteries can be ejected from a battery pack or casing during an incident thereby spreading the fire or creating a cascading incident with secondary ignitions/fire origins.
Even after extinguishing a lithium-ion battery fire, there is a risk of reignition. This is the chain reaction of uncontrolled heating can lead to fire or explosion. Signs of damage or thermal runaway include: Mechanical damage such as cracking (from abuse or dropping/collision). Bulging. Popping/hissing. Visible gases venting. Rising temperature.
Due to the self-sustaining process of thermal runaway, Lithium-ion battery fires are also difficult to quell. Bigger batteries such as those used in electric vehicles may reignite hours or even days after the event, even after being cooled. Source: Firechief® Global

[PDF Version]Germanium-based materials with extremely high theoretical energy capacities have gained a lot of attention recently as potential anodes for lithium ion batteries.
The germanium oxides as raw material for the manufacturing of negative electrodes of lithium-ion and sodium-ion batteries are likely to take leading positions because they simplify technology of the electrodes' production and reduce their price significantly.
The annual world output of germanium does not exceed 130 t. In spite of the basic limitations, studies of the germanium applying in lithium-ion and sodium-ion batteries are continued on a large scale, which is confirmed, in particular, by the recent publishing of review-articles [25, 26, 37 – 47].
Generally, this corresponds to the phase equilibrium diagrams [2, 3]. Germanium was first mentioned as a negative-electrode material in a traditional low-temperature lithium-ion battery in 2004 and 2008 [4 – 8]. In the quoted papers, the above-given composition of the lithium–germanium intermetallic compounds was largely confirmed.
The preparation of germanium materials into nanoparticles, , nanowires, , nanotubes, , or nanofilms structures can significantly increase their specific surface area and lithium ion diffusion rate, thus improving the electrochemical performance of the battery.
