项目摘要
Lithium ion batteries currently a $26.1 billion USD market, however they can only achieve a specific energy of approximately 200 mAh g-1. However, replacing the graphite anode with Li metal, the batteries specific energy can be doubled. Lithium metal are very promising because Li has extremely high capacity (3860 mAh g-1), however the formation of Li dendrite have greatly hindered their practical application. GBatteries has developed a pulsed charging methodology which enables fast charge (up to 10x vs conventional) without detriment to cell performance or lifetime. Applying GBatteries charging protocols we propose to suppress dendrite growth using lithium metal based batteries to that can provide greater energy capacity and be safely operated with longer lifetimes. The proposal would bring together diverse and inclusive experts in Science and Engineering from 4 different universities across Canada. The team will develop new materials for use as solid and liquid electrolytes in lithium metal-based batteries as well as perform specialized characterization (during operation) to study the degradation mechanisms of these new materials and provide solutions for optimization of lifetime with high charge density. Canadian companies will be able to use this technology to create new products, thereby increasing revenue and market penetration. Great energy density and increased life span means smaller batteries that don't need to be replaced as often, which also provides additional environmental benefits to this growing e-waste problem. Finally, in addition to improved batteries, the technology can also reduce greenhouse gas emissions by enabling green technologies.
锂离子电池目前的市场规模为261亿美元,但它们只能达到约200 mAh g-1的比能量。然而,用锂金属代替石墨阳极,电池的比能量可以增加一倍。金属锂由于具有极高的容量(3860 mAh g-1)而非常有前途,然而Li枝晶的形成极大地阻碍了它们的实际应用。GBatteries开发了一种脉冲充电方法,可以快速充电(与传统充电方法相比高达10倍),而不会损害电池性能或寿命。应用GBatteries充电协议,我们建议使用锂金属基电池来抑制枝晶生长,以提供更大的能量容量,并以更长的寿命安全地运行。该提案将汇集来自加拿大4所不同大学的科学和工程方面的多元化和包容性专家。该团队将开发新材料,用作锂金属电池的固体和液体电解质,并进行专门的表征(在运行过程中),以研究这些新材料的降解机制,并提供高电荷密度下优化寿命的解决方案。加拿大公司将能够利用这项技术创造新产品,从而增加收入和市场渗透率。更高的能量密度和更长的使用寿命意味着更小的电池不需要经常更换,这也为日益严重的电子垃圾问题提供了额外的环境效益。最后,除了改进电池,该技术还可以通过启用绿色技术来减少温室气体排放。
