High Energy Density Li-ion Batteries Designed for Low Temperature Applications, Phase I

Completed Technology Project

Project Introduction

High Energy Density Li-ion Batteries Designed for Low Temperature Applications, Phase I
NEI Corporation proposes to develop a mixed metal oxide nanocomposite cathode that is designed for delivering high energy density with good rate performance at low temperatures (T=0 C). The two-fold innovation in the proposed effort is the simultaneous intrinsic (i.e. defect chemistry) and extrinsic (electrically conductive surface coating) modification to the active material, which itself is a composite of two layered materials. The proposed intrinsic and extrinsic modifications are projected to beneficially impact both ionic and electronic conductivities of the cathode material, and thereby enhance the Li-ion cell performance at low operating temperatures. The target specific capacity of the proposed cathode is more than 300 mAh/g with a nominal working voltage of 3V, and delivering more than 900 Wh/kg specific energy at T=0 C. The objective of the Phase I program is to demonstrate the feasibility of a new high capacity and high voltage cathode material for rechargeable Li-ion batteries. In Phase II, the composition and morphology of the powders will be optimized, and integrated into large format prototype Li-ion batteries by working in partnership with a battery manufacturer(s).
