Owing to the sustainability, environmental friendliness, and structural diversity of biomass-derived materials, extensive efforts have been devoted to use them as energy storage materials in high-energy rechargeable batteries. A timely and comprehensive review from the structures to mechanisms will significantly widen this research field. Here, it starts with the operation mechanism of batteries, and it aims to summarize the latest advances for biomass-derived carbon to achieve high-energy battery materials, including activation carbon methods and the structural classification of biomass-derived carbon materials from zero dimension, one dimension, two dimension, and three dimension. Each strategy starts with carefully selected examples and then moves to illustrate the underlying transport mechanism of electrons in the structure. In the end, challenges, strategies, and outlooks are pointed out for the future development of biomass-derived carbon materials. Overall, this review will help researchers choose appropriate strategies to design biomass-derived carbon materials, thereby promoting the application of biomass materials in battery design.

“…[ 4–6 ] As can be seen, high‐performance thermoelectric materials need both excellent electrical transport properties (evaluated by the power factor, S 2 σ) and low κ. Additionally, thermoelectric materials need high zT in a wide temperature range, which can be indexed by average zT ( zT ave ) and determines η at the entire applicational temperature range.

Dense point defects can strengthen phonon scattering to reduce the lattice thermal conductivity and induce outstanding thermoelectric performance in GeTe‐based materials. However, extra point defects inevitably enlarge carrier scattering and deteriorate carrier mobility. Herein, it is found that the interstitial Cu in GeTe can result in synergistic effects, which include: 1) strengthened phonon scattering, leading to ultralow lattice thermal conductivity of 0.48 W m−1 K−1 at 623 K; 2) weakened carrier scattering, contributing to high carrier mobility of 80 cm2 V−1 s−1 at 300 K; 3) optimized carrier concentration of 1.22 × 1020 cm−3. Correspondingly, a high figure‐of‐merit of ≈2.3 at 623 K can be obtained in the Ge0.93Ti0.01Bi0.06Te‐0.01Cu, which corresponds to a maximum energy conversion efficiency of ≈10% at a temperature difference of 423 K. This study systematically investigates the doping behavior of the interstitial Cu in GeTe‐based thermoelectric materials for the first time and demonstrates that the localized interstitial Cu is a new strategy to enhance the thermoelectric performance of GeTe‐based thermoelectric materials.

“…[ 15 ] In fact, in addition to conventional bulk thermoelectric materials that are employed in transitional 3D thermoelectric devices, [ 16 ] developing high‐performance thermoelectric solid‐state and flexible thin films is also of significance to broaden their application scenarios, [ 17 ] such as personal thermal management (PTM) and chip thermal management (CTM). [ 18,19 ] Generally, there are mainly three types of thermoelectric thin films, namely all‐inorganic, all‐organic, and inorganic/organic hybrid films. [ 20 ] All‐organic thermoelectric films composed of conducting polymers usually possess high flexibility, [ 21 ] but their low thermoelectric properties with ZT s of <0.5 limit their applications.…”

Realizing high thermoelectric performance in CoSb3 skutterudite‐based thin films and their devices is historically challenging, especially due to the lack of high‐performing thin‐film‐based device working at medium‐to‐high temperatures. Here, a record‐high ZT of 1.1 is achieved at 683 K in an n‐type Ce0.3Ni1.5Co2.5Sb12 thin film, fabricated from a self‐designed target via advanced pulsed laser deposition. Both experimental and computational results confirm that the Ce‐filling and metal‐featured nanoinclusions such as CeSb contribute to high electrical conductivity, while the Ni‐doping and significantly strengthen the energy filtering effect that occurs at the dense interfaces between the Ce0.3Ni1.5Co2.5Sb12 matrix and the nanoinclusions which leads to a large Seebeck coefficient, giving rise to such a high ZT. In addition, a new‐type CoSb3 thin‐film‐based device is successfully fabricated, which exhibits a high output power density of 8.25 mW cm−2 at a temperature difference of 140 K and a cold‐side temperature of 573 K, indicating the potential for application to medium‐to‐high‐temperature power generation scenarios.
