This year, the battery industry celebrates the 25th anniversary of the introduction of the lithium ion rechargeable battery by Sony Corporation. The discovery of the system dates back to earlier work by Asahi Kasei in Japan, which used a combination of lower temperature carbons for the negative electrode to prevent solvent degradation and lithium cobalt dioxide modified somewhat from Goodenough...

The lithium-ion battery (LIB) is a widely used energy storage system with applications spanning from small electronics to automobiles. An important figure of merit for LIBs is specific capacity, typically reported in mAh/g. One way to improve the overall capacity of LIBs is to replace the ubiquitous carbon anode with silicon or tin, which promise specific capacity of 4,000 and 994 mAh/g, respec...

All‐solid‐state battery (ASSB) technology has emerged as a promising solution for developing safe and high‐energy‐density power sources. However, the pronounced interfacial charge transfer resistance between electrode solid electrolyte continues to be central obstacle in contemporary ASSBs. This work demonstrated first approach printing all‐solid‐state batteries by employing aerosol jet technol...

This paper describes the fabrication of novel modified polyethylene (PE) membranes using plasma technology to create high-performance and cost-effective separator membranes for practical applications in lithium-ion polymer batteries. The modified PE membrane via plasma modification process plays a critical role in improving wettability and electrolyte retention, interfacial adhesion between sep...

In this paper, a model based condition monitoring technique is developed for lithium-ion battery condition monitoring. Here a number of lithium-ion batteries are cycled using two separate over discharge test regimes and the resulting shift in battery parameters is recorded. The battery models are constructed using the equivalent circuit methodology. The condition monitoring setup consists of a ...

A flexible and wearable aqueous symmetrical lithium-ion battery is developed using a single LiVPO4 F material as both cathode and anode in a "water-in-salt" gel polymer electrolyte. The symmetric lithium-ion chemistry exhibits high energy and power density and long cycle life, due to the formation of a robust solid electrolyte interphase consisting of Li2 CO3 -LiF, which enables fast Li-ion tra...

Y uegang Zhang is determined to make a better battery. The physicist and materials scientist started his career developing new ways to manufacture and use carbon nanotubes.

He tested a variety of carbon nanomaterials to m...

A sustainable, heat-resistant and flame-retardant cellulose-based composite nonwoven has been successfully fabricated and explored its potential application for promising separator of high-performance lithium ion battery. It was demonstrated that this flame-retardant cellulose-based composite separator possessed good flame retardancy, superior heat tolerance and proper mechanical strength. As c...

A novel sulfur/graphene nanosheet (S/GNS) composite was prepared via a simple ball milling of sulfur with commercial multi-layer graphene nanosheet, followed by a heat treatment. High-resolution transmission and scanning electronic microscopy observations showed the formation of irregularly interlaced nanosheet-like structure consisting of graphene with uniform sulfur coating on its surface.
