Development of Lithium Ion Battery Technology With Partially Lithiated Cathode and Anode

(Nanowerk News) Superlattice Power, Inc., a company involved in the development and marketing of next generation of lithium-powered batteries, along with all its current developments, is working towards partnering with a major U.S. company to achieve advanced development of lithium ion battery technology with a partially lithiated anode and cathode technology.
Today’s fully lithiated cathode materials with unlithiated anode material exhibits huge capacity loss after few preliminary cycles. It has been observed that metallic oxide anodes have the potential of higher capacity compared to carbonaceous materials. However, currently investigated metal oxide anodes suffer from large irreversible capacity loss initially due to formation of solid electrolyte interface (SEI) and irreversible lithium oxide in metallic oxide anode. It requires a strong effort and many process steps to reduce formation of lithium oxide. The formation of lithium oxide reduces the reversible capacity due to deficiency of lithium ion present in anode structure.
Dr. Vishal Mahajan and Dr. Surajit Sengupta are actively working closely with a major company specialized in lithium technology toward this advancement.
An introduction of partially lithiated anode and cathode in a lithium ion rechargeable battery system will have the major advantages compared to commercially available lithium ion batteries in terms of cycle life and negligible loss of initial capacity loss during first initial cycles.
