About Kesfalo


We are a team consisting of interdisciplinary engineering expertise in materials, chemistry, mechanics and electronics from US, Japan and Taiwan, who started to research what may be brought to disrupt the renewable energy long since 2008. Kesfalo, as a company, is then incorporated in 2013 during the industry development meltdown caused by a major battery startup's disgraceful fallout. Kesfalo team has then set three strategic imperatives as elaborated below, as the immediate objectives, and an achievement update is summarized subsequently. With that, we are now formally entering a company development phase to build our own manufacturing capacity and to expand go-to-market partnership on a global scale.

Strategic Imperative 1. No Compromised User Experiences and only Safer


Batteries are critical components because most modern applications cannot do without them. Their slow improvement in the past compared to other industry developments such as semiconductors, displays and software in an ecosystem, according to batteries’ fair shares, had, too often, forced consumer usability to work around batteries’ limitation. To name one example, modern electric vehicles, unlike their gas-filled counterparts, need to divide users’

charging activities between self-charging at home and charging stations, with the latter asking consumer to allow 30 to 60 minutes for a simple charge, or a 10 times multiple of productivity loss in comparison to gas-filling. With optimizing customers’ ultimate usability in mind, Kesfalo set a very high mark as the technology development objective – Kesfalo’s battery shall be charged to at least 90% full in less than 6 minutes, as Fig 1. illustrates, while the discharge has to be close to 100%, to make possible a better safety protection design for end users.

Strategic Imperative 2. Roadmap of Unfair Advantages against Conventions


The conventional industry wisdom has it since around 2006, by an energy vs power density Regone plot suggested by MITRE Nanosystem Group, as shown in Fig. 2. This projection dictated the battery roadmap during the past decade.

Fig. 2 Energy vs. power Regone plot suggested in 2006

Roughly two camps of industry development emerge in the past decade – one camp aims to push up the maximal energy density of a battery, primarily the lithium-ion based technology. Another camp weighs on the longer term supercapacitor development (Reference: IDTechEx 2016 report), and predicts, by achieving a fraction of battery’s maximal energy density, its total power performance will eventually dominate the market, offsetting its lower energy density disadvantages against batteries. Kesfalo’s aims to do both on our roadmap, by slightly making some room from the top of class lithium-ion process, and integrating what supercapacitor may contribute into a cell unit.

Strategic Imperative 3. DFX (Design For X, X as Manufacturability / Assembly / Testing and, above all, COST)


In addition to an aggressive roadmap, Kesfalo understands, to be competitive in the market, it must be accompanied together a high-yield and low-cost design which requires understanding of material characteristics and process simplification in the very early development stage, after analyzing the fallout of others. The company is incorporated in Taiwan, where all cost effective battery processes are accessible. The team covers feature testing (DFT), manufacturability (DFM) and assembly (DFA) to fit the battery cell design to a standard technology of manufacturing and ensure maximum test coverage. Implementation of this strategic imperative shall eventually prove to bring another critical merit to the end users – COST. A battery of the next generation shall be delivered to be both robust and balanced - including cost to be on the balance.

What Kesfalo has achieved this far


On June 29th, 2016, a new generation of battery, trademarked as HEB (Hybrid Electrode Battery), was given birth by Kesfalo team to take on a Regone plot position as illustrated in Fig.3, upon a fully proven manufacture-able run was conducted.

The following radar chart analysis (Fig. 4) summarizes HEB’s benchmarking data against those of lithium-ion battery according to key attributes. Today,

Kesfalo has delivered the promise and we look forwards to stakeholders’ responses to what we have achieved, and, together, creating a more sustainable ecosystem than what exists today.
