SINGLE-CRYSTALLINE LOW-COBALT TERNARY MATERIAL, METHOD FOR PREPARING SAME, SECONDARY BATTERY, BATTERY PACK, AND POWER CONSUMPTION APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18324592 Titled 'SINGLE-CRYSTALLINE LOW-COBALT TERNARY MATERIAL, METHOD FOR PREPARING SAME, SECONDARY BATTERY, BATTERY PACK, AND POWER CONSUMPTION APPARATUS'
Simplified Explanation
The abstract describes a new type of positive material for batteries, specifically a low-cobalt ternary positive material. The material has a specific chemical formula and a low mole fraction of cobalt. The ratio of cobalt content in the outer layer of the material to the inner core is also specified. This material has improved stability and performance at low temperatures and high voltages, leading to better cycle performance and power output in batteries. The abstract also mentions a method for preparing the material, as well as its potential applications in secondary batteries, battery modules, battery packs, and power consumption devices.
Original Abstract Submitted
A single-crystalline-structured low-cobalt ternary positive material, a chemical formula thereof is Li(NiCoMn)MOA, where a mole fraction of Co element is low. 0.05 ≤ b ≤ 0.14; and in a single particle, a ratio of an average Co content per unit area of an outer layer to an average Co content per unit area of an inner core in a cross section passing through a geometric center of the particle is in a range 1.2-5.0:1, optionally, in a range 1.4-2.0:1 is disclosed. The material has better structural stability and dynamic performance at low temperature and high voltage, which improves cycle performance and power performance of the secondary battery at low temperature and high voltage. A method for preparing the low-cobalt ternary positive material, a secondary battery, a battery module, a battery pack, and a power consumption apparatus including the material is also disclosed
