Battery energy density

Nick Flaherty looks at strategies to get more power out of battery cells, which brings thermal management challenges. There are many ways to boost the energy density of an e-mobility platform’s powertrain. The materials in a battery cell can be improved to produce more energy, from silicon in the anode to new electrolytes. Solid state

Battery sealing

Nick Flaherty assesses the various materials and processes used to seal and protect a battery pack Sealing a battery pack safely is a key requirement for e-mobility systems. While there may be concerns about the ingress of moisture or dirt, there are also issues over venting gasses and preventing electromagnetic interference. As a result...

All-solid-state sodium batteries closer to practical use

Researchers in Japan have developed a process that produces a sulfide solid electrolyte with the world’s highest sodium ion conductivity, writes Nick Flaherty. The synthesised material, developed at Osaka Metropolitan University, is a key contender for all-solid-state sodium batteries. The solid electrolyte, Na2.88Sb0.88W0.12S4, has a sodium ion conductivity about 10 times higher than required for practical use and a glass electrolyte with high reduction resistance.
