Li-ion battery materials: present and future

Ten years left to redesign lithium-ion batteries

“…But they are less efficient at holding charge than cobalt-and nickel-based cathodes (see 'Energy advantage'). Twice as many iron-based cells 8,9 , at nearly twice the cost, are needed to drive the same distance.…”

“…It is produced from sand and stores nearly ten times more lithium ions by mass than graphite does. Combining conversion cathodes with silicon anodes in the next generation of lithium-ion battery cells could allow cells to store more than twice as much energy as the best conventional ones by volume, and more than three times by weight 8,9 . Half as many cells would be required to power electric vehicles, also halving costs, weight and volume.…”

Electrical, Mechanical, and Capacity Percolation Leads to High-Performance MoS2/Nanotube Composite Lithium Ion Battery Electrodes

“…3 A significant problem is that graphite, the dominant anode material used in LIBs, is limited by a relatively low theoretical capacity of 372 mAh/g. 4 As such, the development of the next-generation of LIBs, is expected to see the replacement of graphite-based anodes with alternative materials having higher capacity at similarly low cost. While a range of materials, including silicon, have been envisaged as future LIB anode materials, 4 of particular interest are 2-dimensional (2D) nanomaterials 5 such as graphene 6 and MoS2.…”

Electrical conductivity and porosity in stainless steel 316L scaffolds for electrochemical devices fabricated using selective laser sintering

“…Currently, the development of these devices has become crucial in order to support decarbonisation targets, for example through battery electric vehicles [5,6]. This development faces many challenges, for instance the need to safely improve battery energy density and cycle life, [7,8,9,10]. Researchers have been working over a decade to solve the problems in metal-air batteries such as life cycle limitation, non-uniform zinc dissolution during charge and discharge cycle [11], morphological changes of the zinc electrode [12] and dendritic growth at the zinc anode [13].…”
