Simple, material-efficient microgranulation methods are disclosed for aggregating precursor particles into larger product particles with improved properties and, in some instances, novel structures. The product particles are useful in applications requiring uniform, smooth, spherical, or rounded particles such as for electrode materials in lithium batteries and other applications.

Polytriacetylene, a unique conjugated polymer with all-carbon main-chains consisting of alternating double bonds and diacetylene units, can self-assemble into ordered structures under moderate pressures, driven by side-chain crystallization. At higher pressure, the polymer undergoes topochemical cross-linking reactions, resulting in insoluble materials with graphyne-like structural and property characteristics.

A method for manufacturing cathode active material includes providing a polycrystalline transition metal precursor; providing a lithium salt composition including a first lithium salt and a second lithium salt having a eutectic melting temperature; creating a first mixture including the polycrystalline transition metal precursor and the lithium salt composition; mixing the first mixture in a mixer to generate inter-frictional force to heat the lithium salt composition above the eutectic melting temperature and to generate a second mixture; and sintering the second mixture to form a spinel-coated single-crystal cathode active material.
