Abstract:

LiFePO4 is a commercially available battery material with good theoretical discharge capacity, excellent cycle life and increased safety compared with competing Li-ion chemistries. It has been the focus of considerable experimental and theoretical scrutiny in the past decade, resulting in LiFePO4 cathodes that perform well at high discharge rates. This scrutiny has raised several questions about the behaviour of LiFePO4 material during charge and discharge. In contrast to many other battery chemistries that intercalate homogeneously, LiFePO4 can phase-separate into highly and lowly lithiated p

LiFePO4 is a potential cathode candidate for of secondary lithium batteries due to its low-cost, out-standing thermal stability and innocuity.

LiFePO4 particles produced without any surfactant showed typical morphologies of perfect octahedral with size of ~1μm. For products prepared with addition CTAB, the amount of surfactant controlled the growth of LiFePO4 crystals, with which dif-ferent morphologies of plate, grains and flower-like structures were produced.

During the lithium battery charging process, the occurrence of voltage imbalance will activate the fast balancing mechanism. The expected balancing circuit includes the following features:(1) handling the maximum voltage difference between the odd-numbered and even-numbered battery string without extra energy storage device, thus promoting the working efficiency; (2) requiring only one converter to complete

Abstract:

Lithium iron phosphate (LiFePO4) is a promising cathode material for lithium-ion batteries. In the past few years many improvements have led to consistent cycling capabilities, even at high rates. LiFePO4 is being commercialized as a cathode material in batteries for power tools, and is a serious candidate for the future batteries of hybrid-electric or electric vehicles. It can also be commercialized for other applications requiring a low-cost and safe battery, but its low intrinsic electrical conductivity and low Li-ion diffusion are two major disadvantages. Many groups have shown that batter

An on-line SOH estimation method is proposed in the thesis. It is different from the conventional off-line estimation methods that need to remove battery from the system and connect to other devices. The key component in the proposed SOH estimation procedure is to obtain aging indicators ac
