Tsinghua team develops layered-spinel lithium manganite hydrate for high-capacity and ultrafast lithium storage

Tsinghua University researchers have synthesized a novel layered-spinel lithium manganite hydrate for high capacity and ultrafast lithium storage. A paper on their work is published in the Journal of Power Sources.


The team used a simple one-step hydrothermal lithiation process to create the material.

The layered-spinel coexistence, stable intercalated water, abundant interfaces/defects and mesoporous architectures comprising 2D nanosheets help to shorten the Li-ion transport pathway, promote electronic/ion conductivity, increase Li storage sites and maintain structural stability.

With combined diffusion-controlled and pseudocapacitive reaction mechanisms, the layered-spinel lithium manganite hydrate exhibits superior electrochemical behaviors, showing great potentials for high-capability and ultrafast lithium storage. The comprehensive utilization of multi-phase integration and structural hydration promotes the diversity of material and structure systems, and further paves new way for the design of other high-performance electrode materials.

Could this be the first major step towards future 5-5-5 batteries? If so, can it be mass produced at an affordable price by 2025 or so?


I like the words stable, safe, cheap, fast. Lets see if fast applies getting to market.


Sounds great, when do we get some numbers.
@Harvey, Happy new Year!
I would be happy with 2-2-2 batteries for now, the progress in battery performance is rather slow - it is a very difficult problem, so many variables all have to be managed.
(Energy capacity, Power, Charging rate, Number of charging cycles, weight, volume, safety, cost ...)


@mahonj, and a Happy New Year to you too.

A sunny morning with +2C for the first day of the year in our cold area. Odd temperatures with -20C in November but warmer days in December!

Many new technologies are on the horizon for higher performance mass produced batteries by 2025 or so. Major Chinese manufacturers claim that they can/will mass produce EV batteries at under $100/kWh by 2025 and $50/kWh by 2030/2035.

REs growth rate is getting better every month/year. The new slow turning, much larger 12 megawatt GE Wind Turbines, installed on higher towers in the right places will make a major difference.

Fuel Cell Energy and similar organizations will mass produce containerized transportable storage units with FCs and Electrolisers for 24/7 operations from REs and produce clean H2 for local industries and FCEVs by 2020/2025.

Interesting, but everyone has their own service, I heard a lot of opinions, but some services are fraudsters, I used it many times , I am very pleased with everything quickly and I recommend qualitatively, a large base of high-quality specialists who perform essays.
