Learn MoreSolid-state batteries with no liquid electrolyte have difficulty accessing the lithium in the interior of large polycrystals, and can thus benefit greatly from single-crystal morphology. Including these two, eight publications have compared both the capacity and rate capability of single crystals and polycrystals.
Unlike regular batteries, where the electrodes are composed of tiny particles up to 50 times smaller than the width of a human hair, the single-crystal design appears to resist the damage typically caused by repeated charging and discharging.
The limited specific energy and safety issues of lithium batteries are challenged by the ever-increasing demand of the EV market, leading to the vigorous pursuit of low-cost, high-capacity and high-safety cathodes to enable a long driving range and high-safety lithium batteries.
The single-crystal battery lasted over 20,000 cycles before reaching the 80% capacity threshold, equivalent to driving 8 million kilometres. In comparison, traditional lithium-ion batteries reached the same threshold after 2,400 cycles, demonstrating the significant potential of this technology.
The crack resistance of single crystals extends to calendering, which, combined with their high bulk density, enables electrode-level densities competitive with LCO and surpassing traditional polycrystalline NMC. While the excellent cycle life of single crystals is not in question, other properties are not so well determined.
The lack of grain voids makes the compacted density rise and also increases the electrode volumetric energy density. All of these are due to the special structure of single crystal gives a remarkable improvement in electrochemical and safety performance, which are the main indicators of consumer interests.
