CityUHK Team Secures Funding to Commercialise Next Generation Lithium Rich Cathode Materials
A research team at City University of Hong Kong has secured government backed funding to accelerate the commercialisation of advanced lithium rich cathode materials, aiming to address one of the most persistent technical barriers in lithium ion battery development. The project focuses on overcoming voltage decay in lithium rich layered oxides, a class of materials widely viewed as a breakthrough candidate for next generation electric vehicle and energy storage batteries.
The funding was awarded under the RAISe Plus Scheme launched by the Hong Kong Special Administrative Region government. Led by Professor Liu Qi from the Department of Physics, the initiative seeks to transition laboratory level advances into large scale industrial production within three years. The team plans to establish a 1000 ton annual production line overseas in Southeast Asia or South Korea, building on an existing 100 ton facility already in operation.
Lithium ion batteries remain central to the global energy transition, powering electric vehicles, renewable energy storage systems and a wide range of smart devices. Market projections indicate continued strong growth in battery demand through the end of the decade, with cathode materials accounting for a substantial share of total battery costs. Improving cathode performance while reducing material expenses is therefore critical for both manufacturers and policymakers.
Lithium rich layered oxides offer high capacity and high operating voltage, along with cost advantages linked to relatively abundant raw materials. However, their commercial deployment has been limited by voltage decay and capacity loss during repeated charge and discharge cycles. These issues reduce battery lifespan and undermine performance stability, making large scale adoption challenging.
The CityUHK team has developed a structural modification strategy that incorporates additional transition metal ions into the cathode material to stabilise its internal honeycomb framework. This approach is designed to suppress oxygen release, cation migration and structural degradation, factors closely associated with voltage decline. Complementing this, advanced surface engineering techniques such as carbon coating layers introduced during calcination are used to reduce surface degradation and electrolyte corrosion, further enhancing long term stability.
The research findings were previously published in a leading peer reviewed energy journal in 2023, laying the groundwork for industrial application. The current project aims to translate those results into two product lines, one tailored for conventional lithium ion batteries and another adapted for solid state battery systems. The team estimates that the improved materials could increase energy density in traditional lithium ion batteries by more than 30 percent while helping to lower overall production costs.
The expansion plan is also expected to create around 100 jobs across research, manufacturing and engineering functions. By linking academic innovation with scalable production capacity, the initiative reflects broader efforts to position Hong Kong within the competitive global battery supply chain and to support the rapidly expanding electric vehicle and renewable energy sectors.
