SLAT

Power production has a new standard. Superlattice exhibits power, safety, and environmental concern at a level above anything else. Hybrid Technologies has taken Superlattice from a laboratory scale to industrial scale, and are pioneers in producing nano and submicron materials on a large scale.

Overview 

SLAT (Or Superlattice Power Inc.) has taken a step ahead to pioneer Superlattice Cathode Material for the use in Lithium Ion Rechargeable. HYBT has successfully introduced Superlattice nano and submicron materials from laboratory to industrial scale. 

• Superlattice structure is a hexagonal structure and can accommodate more Lithium and more energy. The elements and specially transition metals have been selected precisely to make Superlattice cathode materials safe, environmentally friendly and less expensive.

 Lithium Ion Batteries

 Lithium Ion Battery is the potential source of rechargeable storage system since it has the capability to provide highest gravimetric (Wh/kg) and volumetric energy density (Wh/L).

 Design

 Cathode materials are the most expensive part of lithium ion batteries. Cathode materials are found in different crystalline structures like layered structure, spinel structure, olivine structure and recently a series of superlattice structures.

 

  

This crystal structure models were examined as [√3X√3] R30°, superlattice. In Figure 3, it can be observed that all transition metal occupy same layer in hexagonal structures and in layered structure they occupy alternative layers. In Superlattice structure some transition metals is substituted by lithium and it enhances the power density significantly. However, superlattice mixed oxide synthesis becomes difficult when starting materials are not mixed homogeneously. An innovative synthesis process is required when large scale production of superlattice cathode material is a major concern.

Development 

Several researchers have investigated high capacity and energy density superlattice structures. However, there is no evidence that it has been produced commercially and in large scale amounts. The critical process optimization required to do so is currently been exhibited by Hybrid Technologies. Hybrid is taking superlattice from a laboratory scale to industrial scale.

The target material is a mixed oxide with a general formulation of Li_1+xMn_aCo_bNi_cTi_dO₂. A series of superlattice cathode materials have been produced under different conditions of time and temperatures.

A process was involved to assure homogeneous mixing of all starting materials. Precursor material was pre-calcined and then subsequently calcined at high temperature ranging 700°C to 900°C.

 

 Project Plan

 

The following is a breakdown of the steps being taken to produce Superlattice technology on a mass scale. This will allow Hybrid Technologies to incorporate the technology into a wide range of products, improving their efficiency.
