There is an ongoing need for higher energy batteries that operate with the highest abuse tolerance. LiCoPO4 is a 4.8 V cathode material with potentially better abuse tolerance and energy density than the current state of art Li-ion battery chemistries. The intense development of high voltage electrolytes1 and strategies that improve the cycle life2, discharge capacity2 and rate capability3 have increased the interest in this material.
This paper will review our recent efforts on LiCoPO4 electrode development. We will discuss synthesis methods, transport measurements, thermal properties and the improvements in discharge capacity and cycle life that result from substitutions to LiCoPO4.
