The inventors 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 and discharge cycles thereby slowing capacity fade. This new additive addition process easily integrate with existing manufacturing process and can also be used with sodium ion batteries.
An important goal of the battery industry is extending battery lifetime. Lithium-ion batteries (LIBs) with high energy densities and good cycling performance are highly desired for the widespread usage of portable electronic devices and the emerging market of electric vehicles. The 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 fullﬁl the increasing demand. Very positive test results have been obtained for these new additives and method that provide numerous benefits over current batteries on the market.
