Alginate-based copolymers as the solid-state electrolyte for Mg battery

The high theoretical volumetric capacity, abundance of magnesium in the earth’s crust, and the relatively good safety features of Mg metal, have drawn great attention to developing Magnesium batteries as a follow-up to the success of Li-ion battery technology. However, the magnesium metal is incompatible with most electrolyte solvents and salts,...

Analysis of the material composition and ionic conductivity of bismuth fluoride and barium tin fluoride and how these factors affect their application in fluoride-ion batteries

In the coming energy transition, the availability of reliable and affordable energy storage will be of vital importance. Battery storage is a large factor in the energy storage sector, and current battery storage is dominated by lithium-based batteries. However, lately, alternatives to lithium have been given renewed attention, due to the...

Electrolyte design for high-energy density Lithium-ion battery with pure Silicon anode

Silicon anodes can boost the energy density of lithium-ion batteries due to its high theoretical capacity up to ~3600 mAh/g. However, a challenge of the use of silicon anode is 300% swelling/shrink upon lithiation/delithiation, which is a major cause of battery failure. A lithium-ion battery with silicon anode requires the formation of a...

Thermal behaviour of lithium-ion batteries and the implications on submarine system design

Submarines face an ongoing (technical) battle to improve the operational effectiveness by increasing the submerged endurance and range. Installing lithium-ion batteries on new or refitted diesel-electric submarines has become increasingly interesting based on their relatively high energy density and specific energy. The characteristics compared...

Si-air Battery: Alkaline cell modelling in MATLAB (Simscape)

Renewable energy sources (RES) such as Solar and Wind energy rely on the availability of natural resources like sunlight in the case of Solar and wind speed in the case of Wind energy generation which is variable in nature. There are periods where there is excess energy production than needed and periods of energy shortage where not enough...

Study on the effects of Doping Argyrodite with LiCl and LiF: in a Solid State Lithium Ion Battery

Solid state lithium ion batteries are generally safer than liquid electrolytes. Li6PS5Cl is a promising electrolyte with an instability in the active material and electrolyte interphase which causes an increase in impedance and capacity loss. <br/>Doping with stable salts of LiCl and LiF could affect the stability. It is found that doping LiCl...
