An important goal of the battery industry is extending battery lifetime. Conventional LIBs are primarily based on graphite negative electrodes (NE) and lithium metal oxide (LMO) positive electrodes (PE) and their energy densities are typically 150 ~ 200 Wh kg-1, which struggle to fulfill the increasing demand.
Inventors at University of Wisconsin, Milwaukee (UWM) have created a family of chemical additives to mitigate lithium-ion losses during solid electrolyte interphase (SEI) formation in Lithium-Ion Batteries (LIB) to meet the ever-growing performance requirements. These chemical additives and methods make extra lithium ions available during charge discharge cycles thereby slowing capacity fade. This new additive addition process easily integrates with existing manufacturing processes and can also be used with sodium ion batteries.
