Problems solved by technology

[0003] However, the current manufacturing process of ceramic battery substrates is not perfect, and the particle size and purity of the powder are not controlled during the production of ceramic battery substrates, resulting in low uniformity of the deposition layer of ceramic battery substrates and high surface roughness of ceramic substrates. The conversion rate of the battery substrate is low

Description

technical field [0001] The invention relates to the technical field of battery substrates for new energy, in particular to a method for preparing a battery substrate with high conversion rate for new energy. Background technique [0002] Battery substrates generally use different materials such as glass, plastic, ceramics, graphite, and metal sheets as substrates. Among them, ceramic substrates have good insulation and stability, and the breakdown voltage is as high as 20KV / mm, which can withstand high current and high voltage instantaneously. mutations to ensure the normal operation of devices and systems; and the thermal expansion coefficients of ceramics and chips are close to each other, so that they will not be deformed too much when the temperature difference changes drastically, resulting in problems such as line desoldering and internal stress. The ceramic substrate has higher thermal conductivity and good heat dissipation performance, and can work in harsh environme...
